Zucchini Quiche Ingredients
- 1 pound zucchini (about 2 medium)
- 1 tablespoon extra-virgin olive oil
- 1 ½ cups sliced leeks (about 2 medium)

- ¾ cup half-and-half

How to Make Zucchini Quiche
- Preheat your oven to 350°F (175°C) and lightly grease a 9-inch glass pie pan with cooking spray.
- Very thinly slice the zucchini using a mandoline or sharp knife to yield about 4 cups. Set aside the remaining zucchini slices for decoration.
- Heat olive oil in a skillet over medium-high heat. Add the leeks, 3 cups of zucchini slices, and 1/8 teaspoon of salt. Cook, stirring often, until softened, about 4-5 minutes. Let cool slightly.
- In a medium bowl, whisk together the eggs, half-and-half, 3 tablespoons of chives, and the remaining 1/8 teaspoon of salt.
- Layer half of the cooked vegetable mixture into the prepared pie pan. Sprinkle with 1/4 cup feta and 1/2 cup fontina. Repeat with the remaining vegetable mixture and fontina.
- Slowly pour the egg mixture evenly over the top. Decoratively layer the reserved zucchini slices on top in a circular pattern, then sprinkle with the remaining 1/4 cup feta.
- Place the pie pan on a rimmed baking sheet and bake in the preheated oven for 35-40 minutes, or until puffed and set in the center.
- Sprinkle with the remaining tablespoon of chives and let cool slightly before slicing. Serve warm or at room temperature for the best flavor.

Zucchini Quiche FAQs
Can I freeze this quiche?
Yes, you can! Allow the quiche to cool completely, wrap it tightly in plastic wrap, then freeze for up to 3 months. For best results, reheat in the oven directly from frozen at 350°F.
How can I make this a dairy-free recipe?
Replace the feta and fontina cheeses with plant-based cheese alternatives and use a dairy-free cream substitute in place of half-and-half.
What can I substitute for leeks?
Onions or shallots make excellent substitutes if you don’t have leeks on hand. Use the same quantity as listed in the recipe.
Can I serve this quiche cold?
Absolutely! It tastes just as delicious chilled, making it a great option for meal prepping or picnics.
Why is my quiche watery?
Excess moisture from the zucchini can lead to a watery quiche. Pat the zucchini dry before cooking and make sure to cook off any excess liquid when sautéing the vegetables.
