Author Notes
I assemble this tomato and gruyere cheese galette by sprinkling shredded gruyere cheese and sweet basil into the center of a cornmeal pastry and top with ripe heirloom tomato slices. Simply fold up the pastry edges to make a free-form tart. There will be streaks of butter when you roll out the pastry but no need to worry. In the oven, those streaks of butter help to create light, flaky, buttery layers. The sweetly salty gruyère melts and the heirloom tomatoes perfectly roast all while nestled within the sides of the golden pastry. This galette is easier to make than a traditional tart and offers a crispier crust. —Kiss the Cook
Ingredients
- Cornmeal Galette Pastry
-
1-1/4 cups all-purpose flour
-
1/3 cup finely ground cornmeal
-
1 teaspoon light brown sugar
-
1 teaspoon salt
-
6 tablespoons unsalted cold butter, cut into 1/2-inch pieces
-
3 tablespoons extra-virgin olive oil
-
1/4 cup ice water
- Galette Filling
-
1 large or 2 medium (about 3/4 pounds) ripe heirloom tomatoes
-
sea salt
-
1 cup shredded Gruyere cheese
-
1/4 fresh basil leaves, chopped
-
2 teaspoons extra-virgin olive oil for brushing
-
freshly ground black pepper
-
1 large egg white, for egg wash
Directions
- Cornmeal Galette Pastry
-
In a medium bowl, mix together the flour, cornmeal, sugar, and salt. Cut in the chilled butter using a stand mixer, a food processor, or a pastry blender until it’s evenly distributed but still in large, visible pieces. Add the olive oil and ice water and mix until the pastry begins to come together. Gather the pastry with your hands and shape it into flattened round. Shape into 2 flattened rounds for 2 small galettes or 1 flattened round for 1 large galette. Wrap the pastry in plastic wrap and refrigerate for 1 hour. If refrigerated longer, let pastry soften slightly before rolling. Can be made ahead and refrigerated up to 3 days.
- Galette Filling
-
While pastry firms in refrigerator, slice the tomatoes about 1/4-inch thick, lightly salt and spread on paper towels to drain. Let set and blot off excess moisture.
-
Place oven rack to the center position and preheat the oven to 375°F.
-
On a large piece of parchment paper which as been lightly sprinkled with cornmeal, roll the dough into a 15-inch round. Place the parchment paper with dough onto a baking sheet. If your baking sheet has sides, flip it over and use the back so that all sides of galette will brown. Trim off excess parchment paper that hangs past the sides of the baking sheet. Lift the sides of the dough with a metal spatula to make sure it’s not sticking.
-
Sprinkle gruyere cheese over the dough, leaving a 2-inch border without filling. Sprinkle basil over cheese. Arrange the tomato slices in a single layer over cheese and basil. Brush the tomatoes with a little olive oil and season with freshly ground black pepper. Fold the flaps of extra dough inward over the tomatoes, pleating as you go, to form a folded-over border. Pinch together any tears in the dough. Brush exposed crust with egg whites.
-
Bake until the crust is golden brown about 35 to 45 min. Slide the galette off the parchment and onto a cooling rack. Let cool for 10 minutes. Cut the tomato gruyere galette into wedges and serve warm or at room temperature.
