1 teaspoon extra-virgin olive oil or butter, for greasing the pan
4 large eggs
2 cups milk
¾ cup all-purpose flour (whole wheat flour also works)
1 teaspoon baking powder

Tip: You’ll find the full list of ingredients and measurements in the recipe card below.

Let’s Get Started

Begin by preheating the oven to 375°F (190°C). Lightly grease a 9-inch pie dish or similar baking dish with olive oil or butter, ensuring the bottom and sides are well coated.

In a large mixing bowl, whisk the eggs until smooth and lightly frothy. Add the milk and continue whisking until fully combined. In a separate bowl, stir together the flour, baking powder, salt, and black pepper. Gradually add the dry ingredients to the egg mixture, whisking continuously to prevent lumps. The batter should be smooth and pourable.

Next, fold in the finely diced onion and the spinach. It’s important that the spinach is thoroughly squeezed dry, as excess moisture can prevent the quiche from setting properly. Gently stir in the crumbled feta cheese, distributing it evenly throughout the batter.

Pour the mixture into the prepared baking dish. Arrange the halved cherry tomatoes evenly over the top, pressing them lightly into the batter so they settle slightly while baking.

Transfer the dish to the oven and bake for 45–50 minutes, or until the quiche is set in the center and lightly golden on top. A knife inserted into the middle should come out mostly clean. Allow the quiche to cool for at least 10 minutes before slicing to help it hold its shape.

Servings and Pairing Variations

This crustless quiche serves 4 to 6 people, depending on portion size. It pairs well with a variety of sides, making it easy to adapt to different meals.

For breakfast or brunch, serve slices alongside fresh fruit, yogurt, or toasted bread. For lunch, a simple green salad with lemon vinaigrette complements the richness of the quiche. At dinner, roasted potatoes, sautéed mushrooms, or a grain salad add heartiness without overwhelming the dish.

Ingredient variations are also easy. Swap feta for goat cheese, add fresh herbs like dill or parsley, or include sautéed mushrooms or bell peppers for extra depth. The base recipe remains flexible while maintaining its structure.

Storage Tips

Crustless Spinach, Tomato and Feta Quiche stores exceptionally well. Once completely cooled, cover the dish tightly or transfer slices to an airtight container. Store in the refrigerator for up to 4 days.

To reheat, warm individual slices in the microwave for 30–60 seconds or reheat in a 325°F (165°C) oven until heated through. The quiche can also be enjoyed cold, making it a convenient grab-and-go option.

For longer storage, slices can be frozen for up to 2 months. Wrap each piece tightly and thaw overnight in the refrigerator before reheating.

FAQs

Can I make this quiche ahead of time?

Yes. The quiche can be baked a day in advance and refrigerated. Allow it to cool completely before storing, then reheat or serve cold as needed.

Why is my quiche watery?

Excess moisture usually comes from spinach that hasn’t been fully drained or tomatoes that release too much liquid. Squeezing the spinach very dry helps prevent this.

Can I use fresh spinach instead of frozen?

Fresh spinach works well. Sauté it briefly, then drain and cool before adding to the batter.

Does this quiche work without flour?

Flour helps give structure. Omitting it will result in a softer, more custard-like texture.

Final Thoughts

Crustless Spinach, Tomato and Feta Quiche is a dependable recipe that combines ease, nutrition, and flavor in one dish. Its no-crust design simplifies preparation while allowing the vibrant ingredients to shine. Whether served fresh from the oven or enjoyed as leftovers, this quiche offers comfort and versatility without extra effort.
