Did you know that quiche actually originated in Germany, not France? The word itself comes from “kuchen,” meaning cake in German.

However, crustless quiche has become increasingly popular for those looking for a healthier, gluten-free option without sacrificing flavor.
Not only is this quiche easy to prepare, but it’s also incredibly versatile. You can enjoy it warm or cold, serve it as a main dish or side, and even customize it with different cheeses and veggies. No matter how you make it, one thing’s for sure—it’s always a crowd-pleaser!

Helpful Tips to Perfect This Recipe
Preheat & Prep Ingredients: First, always preheat your oven to 375°F and prepare all your ingredients ahead of time. This step is essential because it ensures that the fresh spinach, earthy mushrooms, and tangy feta cheese blend perfectly for a balanced and delicious crustless quiche experience.
Sauté Aromatics Thoroughly: Next, make sure to sauté the onions, garlic, and mushrooms until they are soft and aromatic. By doing so, you allow the natural flavors to develop and meld together beautifully, resulting in a rich and flavorful quiche that is both savory and satisfying.
Bake & Rest for Perfection: Finally, bake the quiche until it is set and lightly golden, then allow it to cool slightly before serving. This resting period helps the custard firm up and the flavors to settle, ensuring a perfectly textured and irresistibly delicious dish every time.
