This beautiful free-form galette is the perfect way to celebrate fresh, seasonal summer vegetables!
I remember the days when I was still buying ready-made frozen pie crust from the store, mainly for quiches and chicken pot pie. But ever since purchasing my food processor and my trusty pastry blender, those days are long gone.
If you’ve never made your own pastry crust, I’m here to tell you, you can do it. That all-butter, flaky, delicious crust is, with a little practice, achievable! And since then, I’ve experimented with shortening, butter and shortening, and olive oil.
For me, the crust of the galette is as important as what you put in it. So, I say take the time to make your own. You’ll be so happy you did. For step-by-step instructions take a look at this Cooking Lesson:
I love the rustic, free-form look of a galette. They are so beautiful and versatile. Make it sweet or savory, and use seasonal produce to change it up! No matter what, you’re sure to get lots of ohhs and ahhs if serving this at your next party or gathering.
Summer Vegetable Galette with Pesto
For the crust:
1 1/4 cups all-purpose flour
3/4 teaspoon sea salt
1 stick (1/2 cup) very cold unsalted butter; cubed
1/4 cup ice cold water
1 egg yolk + ½ teaspoon water; slightly beaten (for egg wash)
For the pesto:
1 cup packed fresh basil leaves
1 1/2 cups packed fresh arugula
2 to 3 cloves fresh garlic
1/4 cup pine nuts
1 cup extra virgin olive oil
Kosher salt and freshly ground black pepper, to taste
1/2 cup freshly grated Pecorino cheese
For the galette filling:
1 teaspoon extra virgin olive oil + more for drizzling
1 medium sized yellow summer squash, sliced thin crosswise
1 medium to large sized zucchini, sliced thin crosswise
2 small tomatoes, sliced thin crosswise
Freshly grated pecorino cheese
To make the crust: Combine the flour, salt and cold, cubed butter in the bowl of a food processor, and process for about 5 seconds. Sprinkle the ice water over the flour mixture and pulse until the pastry just begins to come together, for about 10 seconds; you should still see small pieces of butter in it.
Transfer the pastry dough to a lightly floured work surface, gather it together to form a disk or mound, wrap with plastic wrap and refrigerate for at least 30 minutes.
(For step-by-step instructions, see How To Make a Pie from Start to Finish; the pie crust can be made several days ahead and kept refrigerated until ready to make the galette.)
To make the pesto: Clean out the food processor and then combine the basil, arugula, garlic, and pine nuts in the bowl. Pulse until the ingredients are coarsely chopped. With the food processor running, slowly pour the olive oil into the bowl through the feed tube, and process until the pesto is thoroughly pureed. Season with salt and pepper and pulse a few more times. Add the Pecorino cheese and puree until the cheese is thoroughly combined. Transfer the pesto to a jar with a lid or covered bowl until ready to use. The pesto can be made several days ahead and kept refrigerated.
To assemble the galette: Preheat the oven to 375°F and line a baking sheet with parchment paper or a Silpat. Remove the disk of pie dough from the refrigerator and place it on a lightly-floured work surface. Dust some flour on the rolling pin, and roll out the dough to a large circle, about 12 inches in diameter. (If your dough was refrigerated for more than a half an hour, wait about 20 minutes before rolling.)
Using your rolling pin and starting on one end of the dough, loosely roll up your pie crust around the rolling pin. Transfer it to the prepared baking sheet and roll the dough back out flat.
Spread about 1/3 cup of pesto in the center of the dough, leaving about a 1 1/2- to 2-inch border all around the edge. Lightly drizzle on just a touch of extra-virgin olive oil over the pesto. Arrange your sliced summer squash, zucchini and tomatoes in a single layer over the top, arranging them however you want.
Gently fold the pastry border over the vegetables, overlapping the edges as much as possible and creating pleats all around the edges. Brush the folded edges of the crust with the egg wash.
Bake for 35 to 40 minutes, or until the crust is golden brown. Let the galette cool for at least 5 to 10 minutes before serving, and garnish with freshly grated pecorino cheese. Serve the galette with the leftover pesto if desired.
Make-Ahead: You can easily make the pesto and the all-butter dough the day or two before and refrigerate both. For the pesto, make sure you cover your pesto with a thin layer of extra virgin olive oil and cover with plastic wrap or store in a jar with a tight lid. When ready to use the both the dough and the pesto, take out of the fridge and leave on the counter for about 20 minutes.
For the crust: I recommend using a food processor which saves time, but if you don't have one, simply use a pastry blender to break up and combine the cold butter with the flour. This method will take longer.
For the pesto: if you don't like arugula, you can simply use all basil leaves or try basil + baby spinach. Pesto is so versatile, experiment and see what you like.
- I used my mandolin slicer to quickly slice the yellow summer squash and zucchini; this also ensures that the vegetables are the same thickness.
