Variety

  • use different vegetables – Swap 1 to 1.5 cups sliced ​​mushrooms or 5-6 ounces of fresh or frozen spinach for 1 zucchini. (If using frozen spinach, thaw out the water first. You can fry it if you like.)
  • add crust – Use your favorite delicious pie crust and bake it first.I like Almond Flour Pie Crust or Coconut Flour Pie Crust, but any type you like will do. You will need to slightly reduce the amount of eggs and cream to get the filling to fit.

Storage Instructions

  • Shop: Store leftovers in an airtight container in the refrigerator for 3 to 4 days.
  • Meal preparation: Sauté all vegetables ahead of time, then assemble when ready to bake.
  • Reheat: You can heat individual slices in the microwave or reheat the entire quiche in a 350°F oven until hot.
