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.

Stuffed Pastry with Swiss Chard and Feta
It appears that many cultures have a traditional stuffed pastry snack, at least in the Mediterranean. In Greece, Spanakopita is a popular appetizer made with phyllo dough, spinach and feta cheese. I also just learned about an Israeli stuffed pastry, Bureka, pronounced börek. Like spanakopita, it originated from Greece and Turkey but landed in Israel. Essentially, Burekas are individual stuffed pastry made with puff pastry or phyllo dough and filled with a savory filling of meats, cheese or vegetables.
Earlier this week I really wanted to bake, but I was in the mood for something savory. Unfortunately, I do not have a lot of savory baking recipes in my memory box, so I looked to a new cookbook I borrowed from the library, Breaking Breads by Uri Scheft. Uri Scheft is a baker from Israel and owns bakeries in Tel Aviv and New York City. His cookbook focuses on Israeli bread baking. This is a wonderful cookbook with clearly written instructions along with photographs featuring each step. Reading this cookbook is like having Uri Scheft standing at your side and calmly teaching you how to bake bread.
Savory Stuffed Pastry
I did not have the time to bake bread and go through the different proofing stages so I decided to bake one of the burekas recipes featured in his cookbook. The photograph of the Swiss Chard bureka was so appealing and I could clearly visualize a group of friends sitting around a table, having drinks, eating burekas with tahini, olives and pickles. It was an all are welcome greeting with a large platter of delicious bites.
At the time, there were three things that attracted me to the recipe: the photograph as mentioned earlier, Swiss chard, and store-bought pastry dough. As Uri points out, puff pastry is very difficult for the average home baker to make, so buying puff pastry is a great time-saving alternative. I like to make a lot of food from scratch, but now puff pastry dough is out of my league. Buying it saves me a lot of time and worry.
I love braised Swiss chard. This leafy green is not as soft and mild as spinach, or bitter and tough like kale. It stands between the two in flavors and texture. I also love the vivid yellow and purple stems in rainbow chard. Swiss chard has a great balance of body and flavor that is not too bitter. With a sprinkle of lemon zest over Swiss chard and this bitter green vegetable really brightens up.

Uri Scheft’s recipe had all my favorite ingredients with the convenience of store-bought puff pastry dough and I was eager to try it. This is not a difficult recipe to make, but working with puff pastry has its challenges. Each time I bake with it I get a different outcome. So clearly, there is more I should learn. However, listed here are a few key considerations when baking with puff pastry.
Good to know tips working with stuffed pastry
Look for good quality puff pastry made with all butter. The butter helps the laminating process of the pastry and creates the flakes.
My purchased puff pastry came in a one pound box with 2 sheets. The recipe calls for 5 strips of pastry cut at least 4 inches wide and about 12 inches long. How you figure the placement and division of the strips is up to you. I pinched the two pieces together and rolled out the pastry to the dimensions I needed. Unfortunately, I did not achieve a lot of puff. This could be for many reasons, one being the pastry dough is made with vegetable oil and not butter. Or, the dough was too warm. I often find the layers stick together. Here is a great article from Bon Appetit about working with puff pastry dough.
Remove as much of the liquid from the cooked vegetables drained out. Excess liquid will make the pastry soggy and weigh it down. Gently press on the vegetables in a fine mesh strainer with the back of a wooden spoon. Be careful not to mush the vegetables.
Make sure the prepared filled pastries are cold before you put them in a preheated oven. Either place in the freezer for twenty minutes or refrigerate for one hour. Don’t skip this step. The butter in the pastry dough must be cold to create a nice flaky pastry.
Advance preparation: Make the bureka and place them on a rimmed baking sheet in the freezer. Once they are frozen, put the burekas in a freezer bag and keep in the freezer for up to a month. When you are ready to bake, paint the egg wash over the frozen burekas and place them directly on a hot baking stone or an upside rimmed baking sheet in the preheated oven. Bake until golden brown.
For the Love of New Discoveries
I am sure by now you know how much I love learning about new foods and techniques. Cooking and baking is always a process of discovery, whether I made the dish for many years or just for the first time. New discoveries energize me and make me more curious. I was thrilled to learn about this savory stuffed pastry and hope to perfect my technique as I continue to make them. Happy cooking.

Stuffed Pastry with Swiss Chard and Feta
Stuffed pastry with Swiss chard and feta cheese makes a great appetizer or serve for any meal of the day. This recipe is an adaption of a traditional Israeli snack called Bureka. Serve with yogurt tahini spread, olives, and hard-boiled eggs, to create the perfect al fresco meal. Please don't be discouraged by the long prep time. Most of the prep time is waiting for the dough to chill, or the vegetables to cool. With the cooling and chilling time in mind, just make sure you have plenty of time to make these savory stuffed pastries. This stuffed pastry recipe can be made in advance and frozen for up to one month for your convenience. This recipe is slightly adapted from Breaking Breads by Uri Scheft.
Swiss Chard Filling
- 12 oz 342 g Swiss chard
- 5 oz 142 g spinach, tough stems removed
- 1 TB 100 g olive oil
- 1/2 yellow onion finely minced
- 2 celery stalks and leaves thinly sliced
- 1/2 tomato seeds removed and chopped
- 2 cloves garlic minced
- Juice and zest from 1/2 a lemon
- 1/8 tsp red pepper flakes
- 1/2 tsp Kosher salt
- Fresh ground pepper to taste
- 1 lb 455 g store-bought puff pastry - thawed if frozen
- All-purpose flour for rolling the pastry dough
- 1 1/4 cups 150 g feta cheese, crumbled
- 1 large egg
- 1 TB water
- For Garnishing
- Garnish with sesame seeds poppy seeds, everything bagel mixture, or dried herbs and spices
Swiss Chard Filling
Clean the Swiss Chard and remove the stems from the leaves. Cut the stems into 1/4 inch (.5 cm) chunks and set aside. Stack the chard leaves on top of each other and slice across the width into 1 inch (3 cm) ribbons. Then cut the ribbons in half across the width. Set aside.
Prepare the spinach the same as the Swiss Chard, but discard the stems. If you are using baby spinach there is no need to chop the leaves. However, remove any long stems from the baby spinach.
Turn the heat to medium and heat the olive oil in a large 10-inch skillet. Add the minced onion, celery and Swiss chard stems and 1/4 tsp of Kosher salt to the skillet and cook until softened, about 5-8 minutes. Stir occasionally to prevent browning.
Add the chopped tomato, garlic, lemon zest, red pepper flakes, and a couple of grinds of fresh black pepper. Cook the vegetables until the tomatoes break down about 2 - 3 minutes. Stir the vegetables frequently while they are cooking.
Add half of the Swiss chard greens and 1/4 tsp Kosher salt, and stir and cook until the leaves have wilted. Once the first batch cooks down, add the remaining Swiss Chard and cook until it is all wilted.
Scrape in the spinach leaves in the skillet with the vegetables in two batches. Once the spinach is heated and wilted, add the lemon juice. Stir and taste for seasoning. Add more salt and other seasonings if needed. Remember, the cheese in the filling will add a lot of salt to the bureka, so keep that in mind when you are tasting the vegetables.
Transfer the filling to a bowl and cool completely. The cooked vegetables can be made in advance and kept in the refrigerator for several hours.
Once cooled, place the vegetables in a fine mesh strainer and drain out any excess water. Gently press down on the vegetables without squishing them.
Prepare the Puff Pastry
Make the egg wash. In a small bowl beat the egg, water and a pinch of salt until completely combined. Set aside.
Prepare two large rimmed baking sheets and line with parchment paper.
Lightly flour your work surface and rolling pin. Set the puff pastry on the floured surface, long side facing you, and lightly flour the top of the pastry. Gently roll the pastry into a rectangle about 20 inches (51 cm) by 12 inches (30.5 cm) and 1/16 inch thick. When you roll out the pastry dough, roll the pin in one direction beginning from about 1/3 of the way up from the side closest to you. Switch directions and roll the pin across the width in one direction. And switch again. Turn the pastry over and roll in one direction from each side. Repeat this until you have an even shaped rectangle about 1/16 inch thick. Rolling the pin back and forth confuses the dough and you do not get an even stretch. Be careful not to overwork the dough because it could get too warm. If the dough gets sticky and hard to work with, place on a rimmed baking sheet, cover with plastic wrap and refrigerate for 20 minutes.
Assembly, Chill and Bake
Divide the dough into 5 strips across the width of the pastry dough, about 4 inches (10 cm) wide and 12 inches (30.5 cm) long. Brush each strip with the egg wash. Reserve the egg wash for later.
Divide the sautéed vegetables into 5 equal portions about 1/2 cup (120 ml). Spread the Swiss chard mixture evenly down the middle of each strip. Add about a shy 1/4 cup (60 ml) of feta cheese crumbles on top of the vegetables. (If the dough is difficult to work with, chill it in the refrigerator for 15 minutes.)
Fold the right side of the pastry strip over the filling and even with the left side of the pastry, like closing a book from the back to the front. Press on the edges and seal. Turn the filled pastry seam side down.
Twist each pastry into a spiral and make them into a U shape. Place each pastry on the prepared baking sheets. Place in the refrigerator and chill for one hour. Or place in the freezer and chill for 20 minutes.
Preheat the oven for at least 30 minutes to 400°F (200°C / Gas Mark 6). If you have baking stones add them on the oven racks when you turn the oven on. Or turn a rimmed baking sheet large enough for two or three bureka to fit, upside down on an oven rack. The stones or the baking sheet will get good and hot and help create a crisp crust. If you only have one stone bake the burekas in batches.
Brush the burekas with the egg wash and garnish with sesame seeds, poppy seeds, sea salt, or herbs and spices of your liking. Bake until the burekas are golden brown 30 - 35 minutes. Serve warm or room temperature.
Burekas are best eaten the same day they are made. Store any leftovers covered in the refrigerator for up to 24 hours.
