Total Time


  • 2 cups flour
  • 1/2 teaspoon plus 1 teaspoon salt, divided
  • 1/4 teaspoon black pepper
  • 2 tablespoons (1 1/2 sticks) cold butter, cut into 1/2-inch cubes
  • 1 5.3-oz package of Le Gruyère cheese, shredded and divided
  • 1/4 cup ice cold water
  • 2-3 heirloom tomatoes (about 1 1/2 pounds total), sliced 1/4-inch thick
  • 2 tablespoons olive oil
  • 1 egg


  1. In large bowl, whisk together flour, 1/2 teaspoon salt and pepper. Add the butter and 1/2 cup grated cheese. Working quickly, using your fingers or a pastry cutter, mix the butter and cheese into the flour until mixture is crumbly. Add water and mix until just incorporated. Turn out onto a work surface and shape into a ball. Wrap in plastic wrap and flatten into a disk. Refrigerate for at least 1 hour.
  2. Meanwhile, prepare the roasted tomatoes. Heat oven to 350F. Line a rimmed baking sheet with parchment paper. Arrange tomato slices in a single layer with at least 1 inch between slices (use an additional baking sheet if necessary). Drizzle with olive oil and sprinkle with 1 teaspoon salt. Bake 30-45 minutes, until tomatoes have started to wrinkle and any excess moisture in the pan is gone.
  3. On a floured work surface, roll out dough to about 1/8 thick. Gently transfer to a tart pan (10 or 11 inches in diameter). Press dough into pan with your fingers and trim excess dough around the edges. Layer tomato slices over the dough. Sprinkle tomatoes with remaining cheese. Whisk egg in small bowl and brush over the edges of the dough. Bake 50 minutes. Crust should be golden brown and center should be gently bubbling. Allow to cool completely before cutting and serving.
