  • 1/4 cup (60 ml) cold water

For the Filling

  • 1 tablespoon (15 ml) olive oil
  • 3 cups (about 450 grams) cherry or grape tomatoes
  • 1 ear corn, cut from the cob (about 1 cup)
  • 1 small (8 ounces or 225 grams) zucchini or summer squash, sliced or diced
  • 1 bundle (3 to 4 ounces or 85 to 115 grams) scallions, thinly sliced
  • Kosher salt
  • Freshly ground black pepper
  • 1/2 cup (2 ounces or 55 grams) grated parmesan

For the Glaze

  • 1 egg yolk beaten with 1 teaspoon water

Step-by-Step Instructions

Make the Dough

  1. Whisk the flour and salt together in a large bowl.
  2. Sprinkle bits of butter over the flour and use a pastry blender or your fingertips to work it into the flour until the mixture resembles coarse meal, with the biggest pieces of butter the size of tiny peas.
  3. Add sour cream, lemon juice, and water to the butter-flour mixture and combine with a flexible spatula or spoon until large clumps form.
  4. Pat the lumps into a ball, wrap with plastic or a large piece of parchment paper, and refrigerate for 1 to 2 hours, until firm, or up to 4 days if planning ahead.

Prepare the Filling

  1. Heat a sauté pan with a lid over high heat. Add olive oil, tomatoes, 1 teaspoon salt, and a pinch of red pepper flakes.
  2. Cover the pan and cook, rolling the tomatoes around occasionally for even cooking. After a few minutes, you’ll hear popping sounds as the tomatoes burst.
  3. Once most tomatoes have burst, remove the lid, turn the heat down to medium, and add zucchini chunks. Sauté for two minutes until they begin to soften.
  4. Add corn and cook for one more minute. Stir in scallions, then turn off the heat.
  5. Adjust seasonings—add freshly ground black pepper and more salt as needed.
  6. Transfer the mixture to a large plate and spread it out to cool faster. The filling should be at least lukewarm before assembling the galette.

Assemble the Galette

  1. Preheat the oven to 400°F (200°C).
  2. On a floured counter, roll the dough out into a 12-inch round—no need for it to be perfectly round.
  3. Transfer the dough to a parchment-lined baking sheet. Fold the dough gently, without creasing, in quarters, then unfold it onto the baking pan.
  4. Sprinkle half of the parmesan over the cooled filling and spoon the mixture into the center of the dough, leaving a 2-inch border.
  5. If any liquid has puddled on the plate, try to leave it there as you spoon.
  6. Sprinkle almost all of the remaining parmesan over the filling, leaving a pinch or two for the crust.
  7. Fold the border over the filling, pleating the edge to make it fit. The center will be open.
  8. Brush the crust with the egg yolk glaze and sprinkle the last pinches of parmesan over the crust.

Bake the Galette

  1. Bake for 30 to 40 minutes, or until the crust is puffed and golden brown.
  2. Remove from the oven and let stand for 5 minutes, then slide the galette onto a serving plate.
  3. Cut into wedges and serve hot, warm, or at room temperature.

Make-Ahead Tips

  • The baked galette keeps in the fridge for 4 to 5 days. Reheat on a baking sheet in a 350°F (175°C) oven for about 15 minutes.
  • The dough can be made up to 4 days in advance and stored in the refrigerator.
  • The filling can be prepared a few hours ahead and cooled before assembling.

Customization Ideas

  • Add fresh herbs like basil, thyme, or oregano for extra flavor.
  • Swap in other summer vegetables like bell peppers or eggplant.
  • Use different cheeses such as mozzarella or feta for a unique twist.
  • For a vegan version, omit the cheese and use a plant-based yogurt in the dough.
