The Best Crustless Spinach Quiche

Quick and easy brunch recipes are what my weekends are all about! The brunch recipes that I like to make must have minimal prep and come together pretty quickly so that I can make the most of family time. This Crustless Spinach Quiche recipe is so fast and simple, and on top of that, it tastes amazing! It’s also perfect for meal prep as the leftovers can be eaten cold or reheated easily throughout the week.

I based this spinach quiche off a french version opting for butter and heavy cream to create a rich quiche. I also chose fresh spinach over frozen. Frozen spinach would make the quiche too watery and thawing, squeezing out the water was just one extra step. I always opt for fresh when I have it!

This recipe is also great for people practicing low carb diets. I love throwing in vegetables where I can and it was pretty easy to toss a few low-carb ones into this Crustless Spinach Quiche recipe.

Ingredients

  • Butter: I sauté the onion in butter instead of oil. It gives it so much more flavor, richness and tastes amazing.
  • Onion: Is added for flavor. If you don’t have onion on hand substitute with onion powder.
  • Garlic: Garlic brings an amazing aroma to this crustless spinach quiche recipe!
  • Spinach: I prefer to use fresh spinach in this recipe however if you only have frozen spinach make sure to thaw first and squeeze out as much liquid as possible. After it’s thawed and the liquid has been removed measure out 10 ounces of frozen spinach.
  • Cream: Heavy cream makes this quiche rich and filling! It tastes so luxurious! Whole milk can be used in a pinch.
  • Eggs: One of the main ingredients in any quiche recipe is eggs. They bind all of the other ingredients together and also rise a little while baking, becoming fluffy and lighter.
  • Cheese: I added in Monterey Jack cheese which has a slightly sweet, subtle flavor, however, other cheeses would be great in this crustless quiche recipe as well! Havarti, Gouda, Gruyere, Cheddar, or Muenster are all great options.

How to make Crustless Spinach Quiche

  1. Begin by preheating the oven to 350°F and grease a 9-inch pie pan with nonstick cooking spray. Heat butter in a large skillet over medium-high heat and then add the onion. Cook for 3-4 minutes or until the onion is tender and slightly browned.

Storage & Reheating Instructions

  • Store this Crustless Spinach Quiche in an airtight container in the fridge for up to 4 days. You can eat the leftovers cold or reheat them.
  • Make ahead: Make this quiche a day ahead of time, store it in the fridge (covered with a lid or plastic wrap), and then bake it just before you’re ready to eat!
  • Reheat in the microwave or oven until heated through. If you’re heating it in the oven, you can also cover it with aluminum foil to retain the moisture.

Tips for making a Crustless Spinach Quiche

  • Add some meat! I kept this quiche recipe vegetarian for ease, however, you could easily add in some crispy bacon, diced ham, or a sliced sausage like chorizo to add a little extra protein and flavor.
  • Eat it hot or cold. If you’re in a hurry on a busy morning, you can eat the leftovers straight from the fridge! It’s still delicious, healthy, and filling too.
  • Make it ahead of time! Whether you’re making this quiche for meal prep or a special day like Mother’s Day or Easter, you can make the filling, load it up into the pie dish and keep it in the fridge until you are ready to eat. Then all you have to do is take it out of the fridge and bake it!

Frequently Asked Questions

  • Why is my spinach quiche watery? Spinach can be a little watery when it’s cooked, so make sure when you sauté the spinach, keep cooking it until most of the moisture evaporates.
  • Do you cover a quiche when baking? It’s not necessary to cover this crustless spinach quiche when baking, however, if you’re making a quiche with a crust, it’s a good idea to cover it with aluminum foil to prevent the crust from burning.
