Equipment

Ingredients

  • 4 tablespoons butter
  • 2 large onions sliced thin
  • 1 zucchini sliced into thin rounds
  • 2 cups grape tomatoes
  • ¼ cup Parmesan cheese
  • 1 cup Mozzarella cheese
  • 1 tablespoons fresh chopped basil
  • 1 tablespoons fresh chopped parsley
  • 1 egg mixed with a little milk
  • 1 1 pie dough homemade or refrigerated

Instructions

Prepare the Pie Crust

  • Roll out the pie dough and fit it into an rectangle baking tray that's been lined with parchment paper; place it in the refrigerator while you prepare the zucchini

Prepare the Zucchini

  • Using a mandoline slicer, slice the zucchini into rounds.
  • Slice the grape tomatoes in half; lengthwise.
  • Set the vegetables aside while you prepare the onions.
  • Heat the butter in a heavy skillet.
  • Add the sliced onions and cook until they are soft and golden brown; about 20 minutes.
  • Spread the mozzarella cheese on top of the pie dough.
  • Add the cooked onions on top of the cheese.
  • Arrange the sliced zucchini and then the tomatoes on top.
  • Sprinkle the Parmesan cheese on top of the vegetables and then the basil and parsley.
  • Brush the beaten egg and milk mixture over the entire pie crust.
  • Bake in a preheated 425°F oven for about 20 minutes or until the crust is golden brown.

Notes

Tips

  • Slice zucchini thin and even so it bakes quickly and looks uniform.
  • Use a mandoline or sharp knife for best results.
  • Let onions cook slowly until golden for maximum flavor.
Storage & Make Ahead
  • Store leftovers in the refrigerator for up to 3 days.
  • Reheat in a 350°F oven for 10–12 minutes to crisp the crust again.
  • Tart is best enjoyed fresh; freezing is not recommended.
