Savory Tart with Swiss Chard and Butternut Squash
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.

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.
