Savory Tart with Swiss Chard and Butternut Squash
A tender walnut pastry crust provides the foundation for a savory tart filled with sautéed Swiss chard, leeks, butternut squash, seasoned chickpeas tipped over a ricotta goat cheese spread.
I have wanted to make a savory tart since the first signs of spring and it is about time I finally got around to do it. I am not sure why it took me so long, maybe I was just waiting for Swiss chard to come into season. No matter the reason this is a rustic looking savory tart that fits more into the galette category. What I love about informal free-form tarts is you don’t have to worry about having the right size tart pan. It is so frustrating to read a recipe and get excited to make it only to realize you do not have the right pan.
Originally, I wanted to make Joshua McFadden’s Swiss Chard Galette from Six Seasons Cookbook. I have linked to this cookbook many times as it is one of my favorites and provides me with six seasons worth of inspiration. The walnut pie crust for this savory tart comes from his book. However, I decided to make my savory tart using a different style featuring layers of sautéed vegetables over a ricotta cheese and goat cheese spread.
Savory Tart Success
The key to success making savory tarts with lots of vegetables is you must precook all the vegetables. Skipping this step produces a pastry dough with a soggy bottom and partially cooked vegetables. I also believe you need to chop up the vegetables in such a way that they are large enough to not get lost in the pile, but small enough to not weigh down the tart and fall apart. Mixing greens with chopped vegetables help the vegetables stay put as well.
It is the butternut squash that makes the flavors of the savory tart stand out. The concentrated sweetness complements the bitter flavors from the Swiss chard and gives the vegetable filling body. Without it, it is just Swiss chard spread over pie crust, which would taste fine, but won’t be as impressive.
There are two things I love to mix in with butternut squash, sage and smoked or cured pork like pancetta or bacon. These two pairings, either separate or combined, make up one of the best flavor marriages around. If you don’t eat pork, omit it, but the fresh sage is still a nice addition. I did not add a lot of sage or pancetta, so feel free to play around with the amounts. If you do not like sage, substitute it with fresh thyme or rosemary to your liking.
Another optional ingredient is the ricotta and goat cheese spread. I like it because intermittently you will get a creamy pop of goat cheese with your swiss chard, but it is not necessary. Also, spreading the ricotta and goat cheese over the pie crust prevents it from getting soggy while cooking. If you do not want the cheese, baste an egg wash layer over the pastry dough before you add the vegetables. Like the cheese, the egg wash becomes a protective layer between the pie dough and the vegetables.
Savory Pie Crust
The walnut pie dough is the same recipe used in my Tomato Tart with Ricotta and Mediterranean Seasoning. If you do not eat nuts, please substitute it with the pie crust recipe for my Irresistible Onion Tart.
Savory Tart with Swiss Chard with Butternut Squash
I have a thing for savory tarts and this one has a lovely balance of flavors. This tart is more like a galette with its free-form shape and informal attitude. The sweetness of the butternut squash balances out any bitterness of the Swiss chard and gives this tart character. Additionally, I love the butternut squash with sage and pancetta and use them as my main seasonings in this galette. The pancetta is optional but any smoky cured pork is a delicious complement to the butternut squash. The layer of ricotta and goat cheese is subtle. It melts into the pastry and acts as a barrier preventing the pastry from getting a soggy bottom. To make this a dairy-free galette do not add the cheese. Instead, brush a layer of lightly beaten egg over the pastry before you add the vegetables.
Walnut Pastry recipe is from Tomato Tart with Ricotta and Mediterranean Seasonings. If you do not want a pie crust with nuts, use the recipe from the pie crust in my Irresistible Onion Tart.
Serves 4 to 6
- 1 recipe for Walnut Pie Crust
- 3 TB extra virgin olive oil, divided plus more for the chickpeas
- 2.5 oz (65 g) pancetta chopped in ¼ inch (.5 cm) pieces (optional)
- 1 leek sliced into ¼ inch slices white and light green parts only
- 5-6 oz (150 g) butternut squash, about half of a small butternut squash
- 3 garlic cloves minced
- 1 bunch (12 oz / 350 g) Swiss chard Cleaned
- A few rounds of freshly ground black pepper
- 4 sage leaves minced
- 3 oz (75 g) whole milk ricotta cheese
- 2-3 oz (50-75 g) creamy goat cheese
- ½ cup (3 oz / 84 g) chickpeas, rinsed, dried and skins removed
- ¼ tsp paprika
- Small pinch of dried ground garlic
Walnut Pie Crust
- ½ cup (2 oz/ 58 g) 58 g toasted walnuts
- 1 2/3 cups (7.25 oz / 208 g) all-purpose flour
- 4 oz (113 g) chilled unsalted butter, one stick cut into pieces and kept cold until mixing
- 1 TB (12 g) sugar
- ½ tsp Kosher salt
- 2 TB (30 ml) ice cold water plus more if needed
Walnut pie crust
Place the walnuts in a food processor and pulse until a fine and even crumble. Be careful to not over-process the nuts into walnut butter. Pour the walnuts into a mixing bowl and add the flour, sugar and Kosher salt. Mix the ingredients together with a wire whisk until evenly combined. Add the cold butter pieces to the flour mixture and toss to coat the butter with flour. Smush the butter with your fingers with the flour until you get a pebbly mixture of all different sizes. Add 2 TB of ice water and using your hands briefly toss to mix and form a ball. If the dough seems dry add more ice water, one tablespoon at a time.
Lightly dust your clean work surface with flour and tip the dough ball on the surface. Starting at the upper edge of your dough ball, use the heel of your hand to press down and smear the dough away from you. Continue to smear the dough away from you into a pile until you have worked your way through the ball of dough, about 4-5 smears. Gather the dough and form a round disk. Cover with plastic wrap and refrigerate for at least 30 minutes or up to 2 days. The dough will keep in the freezer for 3 months.
Prep the vegetables
Meanwhile, peel and chop the butternut squash into ½ inch (1 cm) cubes.
Trim the stems off the swiss chard by slicing along both sides of the seam where the stem meets the leafy greens. Make a pile of the leaves and slice across the width in 2-inch strips. Repeat until all the leaves are sliced. Set aside.
Chop the stems into ½ inch (1 cm) pieces.
While you prep the vegetables, If using, brown the pancetta. Add 1 tablespoon of extra virgin olive oil to a hot pan then add the chopped pancetta. Turn down the heat to medium-low and brown the pancetta until the fat has rendered and the pancetta is brown and crispy. When done, remove the pancetta from the skillet with a slotted spoon and place on a plate lined with paper towels. Set aside.
Cook the vegetables
In a Dutch oven or large sauté pan (12 inches / 30.5 cm) add the remaining 2 TB of extra virgin olive oil and heat over medium-high heat. Add the sliced leeks, butternut squash, and a ½ tsp of Kosher salt to the pan then stir so the vegetables get an even coating of olive oil. Cook for 2 minutes then add about a ¼ cup (60 ml) of water to the pan, then cover with a tight-fitting lid. Turn down the heat to medium and cook until the butternut squash just begins to get tender but not fully cooked, about 7 minutes.
Remove the lid and add the swiss chard, in batches. Cover the pan and cook until the swiss chard is wilted and soft about 3-4 minutes. Remove the lid and continue to cook until all liquid (if any) evaporates. Taste and add more Kosher salt if needed and a few rounds of fresh black pepper. Turn off the heat, add the minced sage and stir to mix. Tip the cooked vegetables onto a sheet pan to cool. Set aside.
Prepare the savory tart
Mix together the ricotta and goat cheese in a small bowl until smooth. Set aside.
Mix together the chickpeas, 1 teaspoon extra virgin olive oil, paprika, and granulated garlic until evenly combined. Set aside.
One hour before you plan on baking the galette, preheat the oven to 400°F (200°C) with the oven rack in the middle position. If you have a baking stone or steel, place it on top of the oven rack in the middle.
Place a piece of parchment paper on a large sheet pan, about 12 x 18 inches (30 x 45.5 cm). Set aside.
When you are ready to bake, take the tart dough out of the refrigerator and allow it to rest for 10 minutes. Once rested, sprinkle your counter surface with flour and place the dough in the center. Whack the dough with a lightly floured rolling pin. Whack the dough moving from left to right to flatten it out. Turn the dough a quarter turn and whack 4 more times moving across the disk from left to right. Turn the dough over and repeat 2 more times. This process helps the dough start a nice circle shape. Roll out the dough with your rolling pin starting at the center and roll away from you. Turn the dough a quarter turn and roll across the dough beginning in the center. Repeat. Turn the dough over and roll out the dough until you have a 12-inch (30.5 cm) circle and the dough is about ¼-inch (.5 cm) thick. Dust the countertop with flour as needed to prevent the dough from sticking.
Once you have completed rolling out your dough, place your rolling pin across the middle and lift your pie dough then drape it over the rolling pin towards you. Lift your pie dough draped rolling pin and place it across the center of your prepared sheet pan. Start at the end closest to you and roll the pin away from you while the pie dough eases into place. The edges should overlap up the sides of the rim.
Spread the ricotta and goat cheese over the pastry dough in a smooth and even layer, leaving a border of 1 ½-inches (3.5 cm). Tip the cooled vegetables on the pastry and spread in an even layer over the cheeses.
Top off with the seasoned chickpeas.
Fold over the pastry border up the sides of the vegetables. Pleat the pastry as you go around the circle to keep its shape. You do not need to make fancy pleats or edges. Refrigerate for 30 minutes or freeze for 15 minutes.
If the pastry dough is fragile and starts to break when you lift it up you have two options. 1) Refrigerate the tart for 30 minutes ( or freeze it for 15) until the pastry dough chills and solidifies. 2) I found lifting the edge of the parchment paper at the area where I needed to lift the pastry dough over the vegetables, was an easy way to fold over the pastry dough. Then by moving around the circle, using the parchment paper to lift and guide the dough, until done. Peel away the parchment paper from the dough so that it rests back down on the sheet pan.
Mix the egg with a fork until the whites and yolk are combined. Baste the pastry border with the egg wash in an even layer. Add flakey sea salt, or toasted sesame seeds, or leave plain.
Place the galette in the oven and bake for 45 -55 minutes. The galette is done when the pastry has a deep golden brown color and is flaky.
Remove from the oven and cool for 15 minutes before serving. Best eaten warm and the day it is made.

Tomato Tart with Ricotta and Mediterranean Seasoning
Sometimes when I begin a new cooking project, I need to forge ahead with blind faith and fingers crossed. Lingering in the back of my conscious is a belief that everything will work. The last thing I want to worry about is my latest “masterpiece” ending up in the trash can. This tomato tart recipe is a perfect example of my latest cooking adventure starting with confidence from blind faith.
I have always wanted to make a tomato tart. Every time I see a photograph of one, I drool over the pictures and imagine tomatoes roasting in the oven, cradled in a buttery pastry crust. Unfortunately, I don’t always believe photographs of tomato tarts show any real likeness to a real-life fully cooked one. Tomatoes consist mostly of water and a tart baked with a lot of tomatoes could easily become a soggy mess. So, I often wondered what I was seeing in the tempting photographs was accurate. None the less, I never made a savory tomato pastry, so I can’t say for certain how they look in real life.
Taking inspiration from a cookbook I am reading, Six Seasons, A New Way with Vegetables by Joshua McFadden, I finally managed to motivate myself and make a tomato tart. I also needed to use up some leftover ingredients.. Often some of my best meals are the result of needing to use up the leftover ingredients from a former meal. If you haven’t noticed already, a regular statement of mine is, “I created … because I had leftover… Now … is a family favorite”.
There are two recipes in “Six Seasons” cookbook that create the foundation for my tomato tart recipe: Israeli-Spiced Tomatoes, Yogurt Sauce and Chickpeas, and a recipe for Pecan Pie Dough. The Israeli-spiced tomatoes have a bright flavor that compliments the natural sweetness in fresh summer tomatoes. It is a delicious salad with the yogurt sauce and chickpeas. This recipe gave me the idea of making a tomato tart using the same seasoning and preparation technique for marinating the tomatoes. I also had two ripe heirloom tomatoes on my window sill giving me the use or lose stare-down.
I also wanted to make the nut pie pastry crust, and Joshua McFadden has an alluring recipe using pecans. A tomato tart seemed like the perfect recipe to use a nut pie crust. Plus, and I am always open for any excuse to bake. For my recipe, I substituted the pecans with walnuts and reduced the amount of sugar to one tablespoon.

The biggest challenge when baking tomatoes and pastry dough, is keeping the crust from getting a soggy bottom. If you know the challenges ahead, taking the necessary steps to prevent them, will guarantee a beautiful flaky pie crust. With the two foundation recipes set, I went about making the tart and using a few necessary steps to create a tomato tart with a nutty and flaky crust that was anything but soggy.
For my first step, I par-baked the pie crust. Par-baking a pie crust is a technique used for many types of pies and tarts, like a lemon meringue pie. Partially baking a pie crust before adding the filling helps produce a dry and flaky pie crust. It might take longer to finish the pie, but this technique really works.
Even a par-baked crust needs a layer of protection between the crust and the filling. For this recipe, I decided to baste a thin layer of Dijon mustard across the bottom of the pre-baked crust. The mustard adds some tang and will mix well with the ricotta cheese. If you do not like Dijon mustard, baste a layer of egg wash over the bottom of the par-baked crust. It does the same job as the mustard without adding any additional flavor.

Spread over the mustard, I added a layer of ricotta cheese. Good quality fresh ricotta is so creamy it is worth the higher price. If you can find some at your grocery store, I recommend it. In this tart, the ricotta cheese layer absorbs any of the juices from the tomatoes which helps keep the ricotta from drying out and the crust dry. A lot of tomato tart recipes do not call for ricotta cheese. I added it because it was another leftover ingredient I needed to use up before it expired. The ricotta’s creamy flavor is a nice contrast to the roasted tomatoes. Also, adding the ricotta makes the tart more substantial as a main course for lunch or a light supper.
For the final step, I seasoned the tomatoes and let them marinate for an hour. The salt with the spices causes the tomatoes to release some of their liquid. Later, before I arranged the tomatoes around the tart, I used a paper towel to blot the tomato slices and dry them up a bit. The tomatoes marinate while the crust par-bakes, so no additional time is added to the whole process.
It might seem like a lot of steps, but they all add up and work. The result is a tomato tart with a nutty and flaky crust, with a creamy ricotta and roasted tomato filling. I started making this tomato tart with blind faith and fingers crossed. Fortunately, after thinking ahead I came up with solutions to solve any challenges along the way. With inspiration from creative chefs as guidance, I made a tomato tart that I am proud of. There is no false advertising with these photos. What you see is what you get.

- 4 oz 113 g cold unsalted butter, cut into small pieces (1 stick)
- 2 TB ice cold water more if needed
Walnut Pie Dough - Makes enough for one 9-inch (cm ) single crust pie or galette
Place the walnuts in a food processor and pulse until a fine and even crumble. Be careful to not over-process the nuts into walnut butter. Pour the walnuts into a mixing bowl and add the flour, sugar and Kosher salt. Mix the ingredients together with a wire whisk until evenly combined. Add the cold butter pieces to the flour mixture and toss to coat the butter with flour. Smush the butter with your fingers into the flour until you get a pebbly mixture of all different sizes. Add 2 TB of ice water and using your hands briefly toss to mix and form a ball. If the dough seems dry add more ice water, one tablespoon at a time.
Lightly dust a clean work surface with flour and place the dough ball on the surface. Starting at the upper edge of your dough, use the heel of your hand to press down and smear a portion of the dough away from you. Use only one motion per part. Continue to smear a portion of the dough away from you until you have worked your way through the ball of dough, about 4-5 smears. Gather the dough and form a disk. Cover with plastic wrap and refrigerate for at least 30 minutes or up to 2 days. The dough will keep in the freezer for 3 months.
When you are ready to bake, take the tart dough out of the refrigerator and allow it to rest for 10 minutes. This is also a good time to pre-heat your oven to 400°F (204°C). If you have a baking stone place it on a rack in the middle of the oven. Once rested, sprinkle your counter surface with flour and place the dough in the center. Whack the dough with a lightly floured rolling pin. Whack the dough moving from left to right to flatten it out. Turn the dough a quarter turn and whack 4 more times, moving across the disk from left to right. Turn the dough over and repeat 2 more times. Turn the dough over again and repeat. This process helps the dough to form a circle shape.
Roll out the dough with your rolling pin. Always starting at the center of the dough, place your rolling pin in the center and roll away from you. Turn the dough a quarter turn and roll across the dough beginning in the center and roll out. Repeat. Turn the dough over and roll out the dough until you have a 12-inch (30 cm) circle and the dough is about 1/4-inch (6 mm) thick. Dust the countertop with flour as needed to prevent the dough from sticking.
Once you have completed rolling out your dough, place your rolling pin across the middle and lift and drape the dough in half over the rolling pin and towards you. Lift your pastry draped rolling pin across the center of a 9-inch (23 cm) tart pan with removable bottom, and unfold the dough over the pan. Lift the dough edges and ease the dough into place, carefully pressing the dough into the corners without stretching it. Trim the edge of the dough and fold over, into the tart pan to form a thicker tart side. Press the sides of the dough up against the side of the tart pan and even out the edge. Fix any cracks. You want the sides of the tart pastry to be even all around and not too thick. Loosely cover with plastic wrap and refrigerate for 30 minutes.
Par-bake the walnut pie dough. Once the dough in the tart pan has chilled for 30 minutes, cover the dough with aluminum foil and make a well. The foil should be wider than the tart pan to lift the sides and remove it filled with the pie weights. Fill the interior of the foil well with pie weights or dried beans. Spread them out so they evenly cover the surface of the tart bottom. Place the tart pan on a sheet pan then place the whole thing on the middle rack or baking stone. Bake for 15 minutes then remove the aluminum foil with the pie weights off the tart shell and remove. Turn the heat down to 325°F (162°C) and continue baking for 20 minutes. You want to dry out the crust, but not let it get too brown. Reduce the heat to 300°F (149°C) if the crust edges start to get too dark. Remove from the oven and cool on a cooling rack for 15-20 minutes. Turn the oven temperature up to 375°F (190°C)
Meanwhile, while the dough is chilling for the first time (before you roll it out), mix together the minced garlic, sumac, ground colander, ground cumin, Kosher salt, and red pepper flakes into a small bowl.
Slice the tomatoes into thick slices across the middle about 1/4-inch (6 mm) thick. Set the tomato slices on a sheet pan in one layer. Sprinkle the seasoning evenly over the tomatoes and let it marinate for one hour.
In a small mixing bowl, stir until smooth and creamy the ricotta cheese, lemon zest, minced lemon thyme, and basil. Taste the ricotta. If your fresh ricotta is salty leave it alone. If you think it needs salt, add about 1/4 tsp Kosher salt and stir to combine. Set aside or refrigerate until needed.
While the par-baked tart shell is cooling, line a couple of plates with paper towels. Place the seasoned tomato slices on the paper towel lined plates, seasoned side facing up. Pour any tomato juices and seasoning into the bowl with the ricotta cheese and stir.
Once cooled baste a thin layer of Dijon mustard across the bottom of the tart pastry. If you are not a fan of mustard, baste a lightly beaten egg across the bottom of the tart.
Spread the ricotta cheese evenly over the mustard in the tart.
If using, sprinkle a light layer, about 1-2 TB, of Pecorino Romano cheese over the ricotta cheese.
Layer the tomato slices, seasoned side up, evenly around the tart in a decorative fashion. You will need to overlap each slice because they will shrink while baking. If you have large heirloom tomatoes, you might need to cut them in half to fit as many tomatoes as you can in the tart pan. Any leftover tomato slices you can eat for lunch or a delicious snack.
If using, lightly sprinkle Pecornio Romano cheese over the tomatoes, then drizzle extra virgin olive oil over the tomatoes.
Place the assembled tart on a sheet pan, then place in the oven. Bake for 30 minutes, then check to see if the crust is browning too dark. If the crust edge is browning too quickly, cover the rim with aluminum foil, but careful not to cover the tart filling. Continue baking, checking the tart every 10 minutes or less, when you get closer to the end. It could take around 50 minutes total time. The tart is done when the juices throughout the tart bubble, the tomatoes are shriveled, and the Romano cheese begins to brown on top. Also, when the crust has a nice golden-brown color.
Remove the tart from the oven and cool on a cooling rack for 20 minutes.
Remove the tart pan rim. Carefully place the tart on top of a large can of tomatoes or other can or bowl with a secure flat top. Carefully hold the pan rim and slide it down off the tart. Place the tart on a cooling rack and continue to cool. When cool use a wide spatula to help slide the tart off the bottom portion of the tart pan. (Or you can leave it alone if you don't want to take any chances). Garnish right before serving with fresh lemon thyme and born fresh basil leaves.
Serve warm or at room temperature. Best eaten the day it is made.
Sumac is the ground berries from a Sumac bush. It has a slightly bitter taste and a popular seasoning in Mediterranean cuisine. There is no great substitute to resemble it. If you do not have it, or cannot get it. Sprinkle finely grated lemon zest over the tomatoes when it is done baking.
If you do not own a tart pan, you can make this tart a galette. However, there are some changes in the preparation and baking. There is no need to par-bake the dough. After rolling out the dough, Move the dough to a sheet pan covered with parchment paper. Arrange the tart ingredients over the pastry dough in the same order as in the instructions, leaving a 2-inch border. Fold the rim of the dough over the ingredients and pleat to seal. Refrigerate the galette for 30 minutes. Brush the dough with melted butter, olive oil, or egg wash and bake, following the instructions above.
