A very flavorful crustless spinach quiche is perfect for breakfast, lunch, or meatless dinner. I bake two at a time, to ensure I have yummy leftovers!
Crustless quiches are awesome. I do love a flaky crust – who doesn’t! But as good as the crust is, I no longer feel it’s worth the extra carbs. After all, most of the flavor is in the filling.
I especially like this crustless spinach quiche. It’s very easy to make, and – just as important – it’s very tasty. The combination of spinach, garlic, and Parmesan is wonderful.
The ingredients you’ll need
You’ll only need a few simple ingredients to make this tasty quiche. The exact measurements are included in the recipe card below. Here’s an overview of what you’ll need:
Frozen chopped spinach: I never tried making this recipe with fresh spinach.
Eggs: I use large eggs in most of my recipes, this one included.
Plain Greek yogurt: Sour cream should also work.
Kosher salt and black pepper: If using fine salt, you might want to reduce the amount you use.
Garlic powder and onion powder: Make sure they are fresh. A stale spice can easily ruin a dish.
Grated Parmesan: It’s best to use finely grated cheese, not coarsely shredded.
How to make a crustless spinach quiche
It’s so easy! Scroll down to the recipe card for the detailed instructions. Here are the basic steps:
1. Your first step is to defrost the spinach. To do that, you place the spinach in a microwave-safe bowl. Add 1/2 cup water. Cover and microwave until thawed, about 4 minutes.
2. Now, squeeze the spinach dry. Allow it to slightly cool, then place the thawed spinach in a clean kitchen towel and squeeze it hard to get rid of excess liquid. This is an important step that prevents the quiche from being soggy.
3. In a large bowl, whisk together the eggs, yogurt, kosher salt, pepper, garlic powder, onion powder, and parmesan. Then stir in the defrosted spinach.
4. Next, you pour the mixture into the a pie plate and bake the quiche until it’s puffed and fully cooked. This should take 30-40 minutes in a 350°F oven.
5. The last step is to cool the quiche for 20 minutes in the pan on a cooling rack before slicing and serving.
The only somewhat challenging part of this recipe is ensuring that the defrosted spinach is as dry as possible. You’ll need to really squeeze out as much water as you possibly can.
How to serve this quiche
This crustless spinach quiche is perfect for brunch or for a light dinner. It tastes great warm or at room temperature.
I’ve been known to sneak a slice straight from the fridge! It tastes great even when cold.
Quiches are obviously great for brunch, but I often serve this one for dinner. It’s substantial and filling enough. I pair it with a simple tomato salad or an arugula salad for an easy and quick meatless dinner.
What about leftovers?
I usually bake two quiches. We have one for dinner, and the second is my lunch for the next four (or two!) days.
This crustless spinach 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.
