Ingredients You’ll Need
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
Here’s everything required to bring this crustless quiche to life:
- 1 teaspoon extra-virgin olive oil or butter, for greasing your pan
- 4 large eggs
- 2 cups milk (whole, 2%, or your preferred type)
- ¾ cup all-purpose flour (whole wheat flour also works)
- 1 teaspoon baking powder
- 1 teaspoon kosher salt
- ¼ teaspoon black pepper
- 1 small onion, finely diced
- 16 oz frozen spinach, completely thawed and squeezed dry
- 8 oz feta cheese, crumbled
- 1 pint cherry tomatoes, halved (or ½-inch tomato slices)
Each ingredient adds something special—spinach for earthiness, tomatoes for freshness, feta for salty tang, and a simple egg-and-flour base for structure and richness.
Let’s Get Started
1. Prepare the Pan
Preheat your oven to 375°F (190°C). Lightly grease a 9-inch pie dish or similar baking dish with olive oil or butter. This helps prevent sticking and ensures smooth slicing later.
2. Mix the Egg Base
In a large bowl, whisk together the eggs and milk until smooth. In a separate small bowl, combine the flour, baking powder, salt, and black pepper. Add the dry mixture to the egg mixture, whisking until no lumps remain. The batter should be silky and pourable.
3. Add the Veggies and Cheese
Fold in the diced onion, well-drained spinach, and crumbled feta. Be sure your spinach is squeezed as dry as possible—excess water can make the quiche watery.
4. Add Tomatoes
Gently fold in half the tomatoes. Reserve the rest to arrange on top for a beautiful finish.
5. Pour and Arrange
Pour the mixture into your greased baking dish. Scatter the remaining tomato halves on top, cut side up for the prettiest presentation.
6. Bake
Bake for 45–55 minutes, or until the quiche is set in the center and lightly golden around the edges. A knife inserted into the middle should come out clean.
7. Rest and Serve
Let the quiche cool for at least 10 minutes before slicing. This allows the custard to set fully and makes slicing easier.

FAQs
Can I use fresh spinach instead of frozen?
Yes! Use about 10 ounces of fresh spinach, sauté until wilted, and remove as much moisture as possible.
Why does a crustless quiche need flour?
The small amount of flour helps give structure so it slices cleanly without a crust. It also creates a light, almost souffle-like texture.
Can I make this dairy-free?
Absolutely. Use plant-based milk and vegan feta. The texture will still be tender and delicious.
Why did my quiche turn out watery?
This usually happens when the spinach isn’t squeezed well or too many high-moisture vegetables are added. Make sure your spinach is completely dry.
Can I bake this in a different dish?
Yes—an 8×8 casserole dish or a deeper pie plate works well. Just adjust baking time as needed.
