Why You’ll Love This Crustless Spinach Quiche Recipe
Ingredient Notes
- Eggs — To get the perfect custard-like texture, you need the right ratio of egg to dairy. Be sure to use large eggs.
- Spinach — Give it a good rough chop and remove any long stems that may still be attached.
- Sweet onion and garlic — The base for any tasty dish, these add loads of flavor to the greens.
- Milk and sour cream — I prefer whole milk, but either light or full fat versions will work for this recipe. For extra creaminess, add a splash of heavy cream. You could also replace the sour cream with plain or Greek yogurt.
- Cheese — Shredded mozzarella melts like a dream and makes this dish extra creamy, but feta cheese is the true star. Buy a package of crumbles or break apart a fresh block by hand.
- Toppings — Before baking my crustless spinach quiche, I like to sprinkle it with freshly grated Parmesan and smoked paprika. It adds a little extra flavor and a touch of color.
How to Make Crustless Spinach Quiche with Feta Cheese
Beating the eggs well incorporates air into the quiche filling to give this dish a little extra lift.
STEP 1 | Cook the vegetables
Sauté the onion slices in olive oil in a large skillet until tender. Then, stir in the garlic and cook until fragrant.
Add handfuls of chopped spinach to the pan and cook until wilted. Once all of the moisture has evaporated, remove from heat.
STEP 2 | Make the egg mixture
Whisk together the eggs with the sour cream, milk. Season with salt and freshly ground black pepper, then stir in the cheese.
STEP 3 | Combine
Scrape the cooled spinach mixture into the egg mixture. Gently stir until everything is well incorporated.
STEP 4 | Add topping
Pour the mixture into a greased 9-inch pie plate. Sprinkle grated Parmesan and smoked paprika evenly over the top.
STEP 5 | Bake
Place the pie dish on the center rack in the preheated oven. Bake until the center of the quiche is no longer jiggly and the top is golden brown.
Let it rest for 5-10 minutes to finish setting, then slice and serve warm.

Variations and Substitutions
- Frozen spinach may be used in this recipe, but be sure to thaw first and squeeze out any excess moisture.

Storage and Reheating Tips
- To reheat leftovers, remove the dish from the refrigerator, letting it sit on the counter while you preheat the oven. Bake at 350 degrees for about 20 minutes or until warmed through.

Frequently asked questions
With or without a crust, quiches are baked in a pie pan from start to finish and all of the filling ingredients are mixed together.
Frittata, on the other hand, is prepared in a skillet on the stove and often just finished in the oven. It’s more similar to an omelet, where the veggies and meat are cooked first; then the eggs are poured over the top. It also tends to have a higher ratio of eggs to dairy, if milk or cream is even used at all.
First, always let your quiche rest for at least 10 minutes after baking. It will finish setting up as it cools, allowing each slice to hold its shape.
Be sure to cool the vegetables until all of the moisture evaporates as well. Any extra liquid will affect the overall texture.
If the center is still runny or watery, it’s possible that the ratio of dairy to eggs was off. Be sure to use large eggs so the mixture will set properly.

Notes
- Start checking your crustless spinach quiche during the last 5-10 minutes of baking. Every oven is different, so baking time can vary.
- Not all pie plates bake the same! Metal will heat much too quickly and can cause the outer layer to burn. Ceramic will bake evenly and consistently, but glass is fine for this recipe as well.
- You can place your pie plate on a rimmed baking sheet so it’s easier to transfer in and out of the oven.
- To reheat the quiche, remove the dish from the refrigerator, letting it sit on the counter while you preheat the oven. Bake at 350 degrees for about 20 minutes or until warmed through. You can also reheat individual servings in the microwave or air fryer if you prefer.

My go-to frittata. It’s in the oven again right now. I only tweak slightly by adding another clove of garlic and less cheese (just about a 1/2 cup of freshly shredded parm). The paprika is a great touch!
Question for Crustless Spinach Quiche: Do I need to drain the spinach mixture after I cook it before adding it in the other ingredients?
Mattie, no need to drain the spinach. Just cook it until most of the moisture evaporates, then cool slightly before adding to the egg mixture.
