Give me all the easy breakfasts, please and thank you. Especially as school is starting back up and mornings get a little crazier than they are in the summer, a simple breakfast can go a LONG way. Can I get an amen? Enter this delicious and simple crustless spinach quiche.

Packed with spinach, cheese, onion, garlic, and eggs, it’s got all kinds of nutrients and yummy flavors to fill you up right at the start of the day. (Or if you’re more of a breakfast-for-dinner crew, this is a perfect option to end the day, too!) I love that it’s low-maintenance, but there’s also plenty of room to improvise.

Step #4. Bake 30 minutes or until the eggs are set. Let cool 10 minutes then serve.

Is a frittata the same as a crustless quiche?

The main difference between a frittata and crustless quiche is that frittatas have no or very little milk or cream, while quiche do have milk or cream. Plus, frittatas are first cooked on the stove, while quiche is normally completely baked in the oven once you add the eggs to the pan.

How long does crustless quiche last in the fridge?

Quiche lasts for up to 3 to 4 days if stored covered in the fridge. In the freezer, it’ll keep for up to 3 to 4 months.

How do you reheat crustless quiche?

If you want to just reheat a slice of crustless quiche, a simple 45-second zap in the microwave should do the trick (but make sure you cover it with a paper towel). To reheat a larger portion, set your oven to 350 degrees F., cover the quiche with foil, and bake for about 20 minutes, or until heated through.

Can I prep a quiche the night before?

Yes! This is a great dish to bring to a brunch gathering or to have ready for a busy morning. Just cook it the night before, let it cool completely, cover it tightly, and refrigerate overnight. Reheat it in the morning or whenever you’re ready to serve.

Expert Tips

  • If the top starts to brown too quickly (before the eggs are fully cooked), cover it loosely with foil towards the end of the baking time.
  • For the best flavor, use a cheese that has a strong flavor like sharp cheddar, Swiss, or parmesan.
  • You can divide the quiche mixture into a greased muffin tin, bake, and freeze for an easy “grab and go” meal.
  • Squeeze as much of the moisture out of the frozen spinach as you can before adding it to the skillet. The rest will cook out there.

How to Freeze Crustless Spinach Quiche

  • Cool the quiche completely, then wrap it in plastic wrap, and then wrap it again in aluminum foil. You can freeze it for up to two months that way. Thaw it overnight in the refrigerator before reheating.

    Easy and good…..

  2. Rachel >> Strangers on a Plain says:

    This looks so good. I’m trying to break up with my quiche crust but we are dairy free due to allergies. Do you think this would still work without the cheese in it?

    1. Melissa says:

      Yep, I make it really often without the cheese. If you’d like something else in it, like bacon or ham, feel free to add it too!
