A comforting and flavorful savory pie featuring fresh heirloom tomatoes and creamy Gruyere cheese, wrapped in a flaky crust. Perfect for brunch or casual dinners, this pie balances tangy tomatoes with nutty cheese and fresh herbs.

Ingredients

Scale
  • 1 unbaked 9-inch pie crust (homemade or store-bought)
  • 3 large ripe heirloom tomatoes, sliced about 1/4 inch thick
  • 1 1/2 cups shredded Gruyere cheese
  • 1/2 cup mayonnaise
  • 2 large eggs, room temperature
  • 1 teaspoon Dijon mustard
  • 1 teaspoon fresh thyme leaves, finely chopped
  • Salt and freshly ground black pepper to taste
  • 1 tablespoon olive oil, for drizzling
  • 2 tablespoons breadcrumbs

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Set the pie crust in a 9-inch pie dish and prick the bottom lightly with a fork. Chill in the fridge for 15 minutes.
  3. Slice heirloom tomatoes about 1/4 inch thick. Lay them on paper towels, sprinkle lightly with salt, let sit for 10 minutes to draw out moisture, then blot dry gently.
  4. In a medium bowl, whisk together mayonnaise, eggs, Dijon mustard, fresh thyme, salt, and pepper until smooth and creamy.
  5. Sprinkle breadcrumbs evenly over the chilled pie crust.
  6. Layer Gruyere cheese, then tomato slices, repeating until all ingredients are used, finishing with cheese on top. Drizzle olive oil lightly over the tomatoes.
  7. Pour the custard mixture evenly over the layered pie.
  8. Bake for 40-45 minutes, until the custard is set and the top is golden brown and bubbly. The filling should jiggle slightly but not be liquid.
  9. Cool the pie for 10-15 minutes before slicing to allow it to set.

Notes

Salting and draining the tomato slices is essential to prevent sogginess. Use room temperature eggs and mayonnaise for a smooth custard. Cover crust edges with foil if browning too quickly. Reheat leftovers gently in a 350°F oven to keep crust crisp. Can substitute mayonnaise with Greek yogurt for a lighter version and use gluten-free crust if desired.
