Recipe FAQs

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 foiltowards the end of the baking time.
For the best flavor,use a cheese that has a strong flavorlike 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 canbefore 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.
