To start with, gather your ingredients. For a basic spinach and mushroom crustless quiche, you’ll need:

  • 1 tablespoon olive oil
  • 1 small onion, finely chopped
  • 2 cups fresh spinach, chopped
  • 1 cup sliced mushrooms
  • 6 large eggs
  • 1 cup milk or heavy cream (for a richer quiche)
  • 1 cup shredded cheese (cheddar, mozzarella, or your favorite melting cheese)
  • Salt and pepper to taste
  • Optional: herbs like thyme or parsley for added flavor

Here’s how to prepare it:

  1. Preheat your oven to 350°F (175°C) and grease a 9-inch pie dish or a similar baking dish.
  2. Sauté the vegetables: Heat olive oil in a skillet over medium heat. Add the chopped onion and cook until softened, about 3-4 minutes. Add the sliced mushrooms and cook for another 3-4 minutes until they are tender and any moisture has evaporated. Stir in the chopped spinach and cook until wilted. Remove from heat and let it cool slightly.
  3. Prepare the egg mixture: In a large bowl, whisk together the eggs and milk (or cream) until well combined. Season with salt and pepper to taste. Stir in the shredded cheese and cooked vegetables. Add any optional herbs if desired.
  4. Assemble and bake: Pour the egg mixture into the prepared pie dish. Spread it evenly with a spatula. Bake in the preheated oven for 35-40 minutes, or until the top is golden brown and the center is set. To check if it’s done, insert a knife or toothpick into the center; it should come out clean.
  5. Serve: Remove from the oven and let it cool for a few minutes before slicing and serving. Crustless quiche can be served warm or at room temperature. It also reheats well, making it perfect for meal prep throughout the week.

Variations: This crustless quiche recipe is highly adaptable. You can swap spinach and mushrooms for other vegetables like bell peppers, zucchini, or broccoli. You can also add cooked bacon, ham, or sausage for a meaty version. Experiment with different cheeses or add spices like paprika or red pepper flakes for extra flavor.

Crustless quiche is not only delicious but also a great way to pack in nutrients from vegetables and protein from eggs and cheese. Whether you enjoy it fresh out of the oven or reheated later, this dish is sure to become a staple in your kitchen for its simplicity and versatility.

Crustless quiche is indeed a versatile and practical dish, especially when accommodating various dietary preferences and avoiding the hassle of making a crust. The spinach and mushroom base recipe you mentioned sounds delicious and nutritious, catering perfectly to both vegetarians and those who need to avoid gluten. It’s wonderful how adaptable it is—you can easily switch up the ingredients to suit different tastes and seasons.

For instance, adding broccoli, cheddar, and diced ham can create a hearty and savory version, perfect for a satisfying meal. On the other hand, incorporating tomatoes, roasted red peppers, and feta brings a burst of summer flavors and a Mediterranean twist. Your idea of using leftover roasted vegetables is brilliant, ensuring nothing goes to waste while transforming them into a delightful quiche.

The beauty of crustless quiche lies in its simplicity and flexibility. Without the crust, you still get all the flavors and textures of a traditional quiche, but with less effort and fewer concerns about dietary restrictions.
