Ingredients

Scale
  • 1 3/4 cups (230g) all-purpose flour
  • 1/2 tsp salt
  • 1/2 cup (120g) cold butter
  • 1 medium egg
  • 12 tbsp cold milk
  • 7 oz (200g) sour cream
  • 2 medium eggs
  • 1.8 oz (50g) Parmesan, finely grated
  • 23 stalks thyme
  • Salt and pepper, to taste
  • Some oil for frying (e.g. avocado oil)
  • 2 small eggplants
  • 1 medium zucchini
  • 34 medium tomatoes
  • 23 red onions

Instructions

  1. In a bowl, mix flour and salt. Add cold butter and rub into the flour until crumbly.
  2. Add the egg and 1 tbsp of cold milk. Mix and knead briefly until a dough forms. Add more milk if needed.
  3. Wrap the dough in plastic wrap and chill for 30 minutes.
  4. Preheat the oven to 375°F (190°C). Roll out the dough and press it into a tart pan. Prick the bottom with a fork.
  5. Pre-bake the crust for about 10 minutes. Remove from oven and let cool slightly.
  6. In a bowl, whisk sour cream, eggs, Parmesan, thyme leaves, salt, and pepper until smooth.
  7. Pour the filling into the pre-baked crust.
  8. Slice eggplants, zucchini, tomatoes, and red onions thinly. Lightly fry them in oil until slightly softened. Season with salt and pepper.
  9. Arrange the sautéed vegetables in a circular pattern over the filling.
  10. Bake the tart for 30–35 minutes, or until the filling is set and the top is lightly golden.
  11. Let cool slightly before slicing and serving.

Notes

  • Use a mandoline for evenly sliced vegetables.
  • Customize with other herbs like oregano or basil.
  • Tastes great warm or at room temperature.
