This flavorful crustless spinach quiche is perfect for breakfast, lunch, or meatless dinner.

I bake two at a time to ensure I have yummy leftovers! They're excellent reheated; you can even enjoy them cold straight out of the fridge.

Crustless quiches are awesome. As much as I like a flaky crust, most of the flavor is in the filling. I enjoy crustless vegetable quiche, crustless broccoli quiche, and crustless quiche Lorraine.

I especially like this crustless spinach quiche. It's easy to make and, just as important, delicious. The combination of spinach, garlic, and parmesan is delightful. It's like eating creamed spinach in a pie form! It's so very flavorful.

Ingredients

Crustless Spinach Quiche - Healthy Recipes Blog (2)

You'll only need a few simple ingredients to make this quiche. The exact measurements are included in the recipe card below. Here's an overview of what you'll need:

  • Frozen chopped spinach: I use it because it's so convenient. I always have a package or two of frozen spinach in my freezer.
  • Eggs: I use large eggs in most of my recipes, this one included.
  • Sour cream: You can use whole milk Greek yogurt instead, but sour cream is richer and better.
  • To season: Kosher salt, black pepper, garlic powder, onion powder, and dried thyme.
  • Grated Parmesan: Using finely grated cheese is best, not coarsely shredded.

Variations

  • You can use whole-milk Greek yogurt instead of sour cream, although sour cream is better. I don't recommend using low-fat yogurt.
  • Add ¼ cup of chopped sun-dried tomatoes.
  • Add ¼ cup of chopped cooked bacon or ham cubes.
  • Before baking, you can sprinkle the quiche with ¼ cup of shredded white cheddar.

Instructions

Making this crustless spinach quiche is easy! Scroll down to the recipe card for detailed instructions. Here are the basic steps:

Place the spinach in a microwave-safe bowl. Cover and microwave until thawed, about 4 minutes. Allow it to cool slightly, then place the thawed spinach in a colander and press on it repeatedly with the back of a large spoon to drain it.

Expert Tip

The only somewhat challenging part of this recipe is ensuring that the defrosted spinach is as dry as possible. But it's important. You'll need to really squeeze out as much water as you possibly can to ensure a firm, non-watery quiche.

Recipe FAQs

Should I cook the spinach before adding it to the quiche?

You should lightly cook it to defrost it and then squeeze out as much liquid as possible.

Why is my quiche watery?

This happens when you don't squeeze out enough of the liquids. Next time, make sure to work hard at getting the spinach as dry as possible.

What's the difference between a crustless quiche and a frittata?

They're similar, but the ratio of ingredients is slightly different. A frittata relies mainly on eggs, while a quiche also has creamy dairy ingredients such as sour or heavy cream.

Traditionally, you would also cook a frittata in a skillet and bake a quiche in a pie dish.

Serving Suggestions

This crustless spinach quiche is perfect for brunch or a light dinner. It tastes great warm or at room temperature.

I've been known to sneak a slice straight from the fridge! It's delicious even when cold.

I also like to serve it for dinner. It's substantial and filling enough. I pair it with a simple tomato salad or arugula salad for a quick and easy meatless dinner.

Storing Leftovers

I usually bake two quiches. We have one for dinner; the second is my lunch for the next few days.

This quiche keeps beautifully in the fridge, in an airtight container, for up to 4 days. You can also slice it into individual slices and freeze the slices.
