This section explains how to choose the best ingredients for a zucchini quiche, what each ingredient does in the recipe, and substitution options. See recipe card below for measurements.
- olive oil – Use your favorite extra virgin oil or any neutral cooking oil.
- onion – Yellow or white onions work best in this recipe.
- zucchini -Obviously it has to be called a zucchini quiche, but yellow squash would work the same way.
- dried basil – you can also use dried oregano, or store bought or homemade Italian seasoning. If you want to use fresh herbs, substitute one tablespoon of fresh for each teaspoon of dried.
- garlic – Fresh garlic will taste the best, but you can also use canned garlic For convenience.

How to Make Crustless Zucchini Quiche
This section describes how to make a skinless zucchini quiche, with step-by-step photos and details on the technique. See the recipe card below for full instructions.
- Fried onions. Heat oil in a large saucepan over medium heat, then add the onions. Cook until translucent.
- Cook the zucchini. Add zucchini and season with basil. Increase heat and cook, stirring occasionally, until squash is tender and beginning to brown.


- Add garlic. Make a well in the center of the vegetable and add the garlic (and more oil if needed). Saute until fragrant, then stir in zucchini and onions.
- transfer. Add half of the zucchini mixture to a 9-inch pie pan. Spread half of the cheese on top. Spread a layer over the remaining zucchini, then the remaining cheese.
Tip: Don’t have a pie plate?
You can also bake this quiche in an 8×8 inch square pan. The cooking time will remain the same.


- brush. In a large bowl, whisk together eggs, cream, salt and pepper. Pour the egg mixture over the zucchini in the pan.
- bake. Bake the zucchini quiche until the eggs are set.


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.
Can you freeze zucchini quiche?
Zucchini Quiche Recipe can be frozen for 2-3 months. Just cool completely, wrap tightly, and freeze. Thaw overnight in the refrigerator, then reheat as directed above.
