Crustless Spanakopita Quiche Recipe With Summer Squash Is Fantastic

I was looking for a way to use the zucchini and yellow squash I had in my fridge when I was inspired by a recipe for a crustless quiche. I wasn't convinced that I was onboard for a quiche with no crust, but this is so good we didn't miss the crust at all. Truth be told, we ate the whole thing in only two days and for three different meals!

I am absolutely going to add this delicious crustless quiche recipe to our regular dinner and lunch rotation – and special events starting with a bridal shower I'm hosting soon! This spanakopita quiche recipe is a keeper!

To make this easy spanakopita and squash quiche you will need the following ingredients: zucchini and/or yellow squash, red onion, olive oil, garlic powder, onion powder, crushed red pepper flakes, eggs, feta, Parmesan, mozzarella, fresh mint, dried oregano, baby spinach, fresh dill and panko breadcrumbs. Serve this amazing vegetable quiche with a side salad for lunch or dinner, or with fresh fruit for breakfast

This quiche is great warm, at room temperature and even cold. To make this recipe gluten-free, use gluten-free panko breadcrumbs.

  • I used two zucchini and one yellow squash for this quiche recipe.
  • You can use regular or gluten-free panko breadcrumbs.

Here's how to make it:

  3. While the vegetables cook, mix eggs, eggs, feta, Parmesan, mint, oregano or Italian spices, spinach, dill, breadcrumbs, salt and pepper in a large bowl.
  4. When the vegetables are out of the oven fold them into the egg and cheese mixture to coat.
