A savory, layered pie featuring flaky crust, nutty Gruyere cheese, fresh thyme, and juicy heirloom tomatoes, perfect for summer gatherings and easy to prepare in under an hour.

Ingredients

Scale
  • 1 9-inch pie crust (homemade or store-bought)
  • 4 cups sliced heirloom tomatoes (about 600g or 1.3 lbs)
  • 1 ½ cups shredded Gruyere cheese (about 150g or 5.3 oz)
  • 2 tablespoons finely chopped fresh thyme
  • ½ cup mayonnaise (120ml or 4 fl oz)
  • 2 large eggs, room temperature
  • ¼ cup grated Parmesan cheese (about 25g or 0.9 oz)
  • 1 clove garlic, minced
  • Salt and pepper to taste
  • 1 tablespoon olive oil

Instructions

  1. Slice heirloom tomatoes about ¼ inch thick. Lay them on paper towels and sprinkle lightly with salt. Let sit for 15 minutes to draw out moisture.
  2. If using homemade crust, roll it out on a floured surface to fit a 9-inch pie dish. Press into dish with about ½ inch overhang. Chill in fridge for 10 minutes.
  3. In a large bowl, whisk together mayonnaise, eggs, minced garlic, chopped thyme, Gruyere, Parmesan, black pepper (about ¼ teaspoon), and a pinch of salt.
  4. After tomatoes have rested, gently pat them dry with paper towels to remove excess moisture.
  5. Preheat oven to 375°F (190°C). Layer half the tomatoes in the chilled crust, slightly overlapping. Pour half the cheese and mayo mixture over tomatoes and spread gently. Repeat with remaining tomatoes and topping mixture.
  6. Fold crust edges over filling or crimp decoratively. Brush crust edges with olive oil. Place pie on a baking sheet to catch drips.
  7. Bake for 40-45 minutes until crust is golden and filling is set (knife inserted near center should come out clean).
  8. Let pie cool for at least 10 minutes before slicing and serving.

Notes

Salting and resting tomatoes to draw out moisture is crucial to avoid soggy crust. Use a sharp knife for even tomato slices. If crust edges brown too fast, cover with foil halfway through baking. Let pie rest after baking for easier slicing and better flavor melding. For dairy-free or vegan versions, substitute Gruyere with plant-based cheese and use vegan mayo and crust.
