Can you reheat this keto breakfast casserole?

Yes, you can reheat this keto breakfast casserole, but we also enjoyed it cold!

To reheat the casserole, you’ll want to let it cool to room temperature and then wrap it up in aluminum foil or plastic wrap.

Then, place it in the refrigerator until you’re ready to reheat it.

Once you’re ready to reheat, you’ll want to place it in an oven at 375˚F for 30 minutes or until the cheese bubbles.

Want to make this Keto Breakfast Casserole ahead of time?

We love making this casserole ahead of time and enjoying it through the week.

Since it doesn’t have potatoes or bread in it, you don’t have to worry about it getting soggy. We typically will bake our casserole the night before and let it cool completely.

Then, we place it in an airtight container or cover it tightly with foil. You can choose to cut it into squares now, or you can leave it in the original baking pan.

To reheat, we place it in the oven or even place a square in the microwave.

What if I want to serve it in a few days?

If you want to make the casserole a few days ahead of time, you can do the same steps as above, but you’ll just want to bake it the day you want to it eat it.

How to Freeze This Keto Breakfast Casserole 

We love freezing leftovers, and this recipe lasts up to 3 months in the freezer!

How to Freeze it Before You Bake It

If you want to freeze the casserole before you bake it, you’ll want to follow the instructions on the recipe card except for baking it.

Instead, you’ll want to cover the casserole with plastic wrap and foil and freeze it.

When you’re ready to enjoy it, we recommend moving it to the refrigerator the night before and letting it sit out for about 30 minutes before baking it as outlined on the recipe card.

How to Freeze it After You Bake It

If you’ve already baked the casserole, you can freeze the leftovers!

You’ll want to follow the recipe card below exactly, and then you’ll want to make sure what you want to freeze is at room temperature before wrapping tightly in plastic and foil and placing it in the freezer.

You can also cut up the leftovers in squares and freeze them in an airtight container separately.
