Ingredients
For the Dough
- 2 1/2 cups flour
- 1 teaspoon salt
- 1 teaspoon sugar
- 1 stick cold butter, cut into 8 pieces
- 1/2 to 2/3 cup ice-cold water
- 1 egg, beaten, for browning crust
For the Filling
- 1 tablespoon olive oil
- 3 cloves garlic
- 1 small red onion, thinly sliced
- 2/3 cup corn (frozen or fresh)
- 2 teaspoons salt, divided
- 2 cups mixed cherry tomatoes, halved
- 1 ball buffalo mozzarella
Instructions
- Prepare the dough: Combine flour, salt, and sugar in a food processor. Add cold butter pieces and pulse until the butter is broken into small pieces integrated throughout the flour mixture.
- Add water cautiously: Slowly add the ice-cold water while pulsing the food processor. Use only as much water as needed to bring the dough together without overworking it; do not pulse longer than 20 seconds at a time.
- Chill the dough: When the dough forms a ball, remove it, divide into two equal balls, cover with plastic wrap, and refrigerate for at least one hour to firm up.
- Preheat oven: Set your oven to 425°F (220°C) to get it ready for baking.
- Sauté aromatics: In a frying pan, heat olive oil over medium heat. Add chopped garlic and sauté briefly for 30 seconds until fragrant.
- Cook onions and corn: Add thinly sliced onions to the pan and cook for about 5 minutes until browned. Stir in corn and 1 teaspoon of salt, cooking for an additional 3 minutes until heated through.
- Prepare tomato mixture: In a medium bowl, combine the sautéed corn and onion mixture with the halved cherry tomatoes. Sprinkle with the remaining teaspoon of salt and gently toss to mix.
- Roll out dough: Remove chilled dough from the refrigerator. On a floured surface, roll it out into a circle about 1/4 inch thick.
- Assemble on baking sheet: Place the rolled dough on parchment paper on a cookie sheet or baking tray.
- Add cheese and filling: Tear the buffalo mozzarella into small pieces and evenly distribute them over the dough, leaving a border. Spoon the tomato and corn mixture on top of the cheese, again leaving about 1.5-inch edges around the dough.
- Fold edges and glaze: Fold the edges of the dough up over the filling, pleating as needed to contain the filling. Brush the exposed crust edges with the beaten egg to ensure a glossy, golden finish.
- Bake the galette: Bake in the preheated oven for 25 minutes until the crust is golden brown and cooked through.
- Cool and serve: Remove from the oven and let the galette cool for about 10 minutes before slicing and serving.
Notes
- You can substitute frozen corn with fresh corn kernels when in season.
- Be careful not to overwork the dough to keep the crust tender and flaky.
- Use a sharp knife to slice the galette once cooled to maintain the shape.
- For a richer flavor, drizzle a little balsamic reduction over the finished galette before serving.
- The recipe can be doubled easily; freeze the second dough ball for later use.
