The components in a good Keto casserole typically include a protein, a vegetable and plenty of healthy fat! For the protein, there are so many that we can enjoy on a Ketogenic diet, including beef, chicken, pork, turkey, seafood and more!

Add in your low carb veggies like cauliflower, spinach, broccoli, spaghetti squash or zucchini.  You can even add in small amounts of onion, garlic or peppers for extra flavor.  

Most low carb casserole recipes will have some type of sauce, typically made from healthy Keto fats like heavy cream, cream cheese, sour cream, mayonnaise, mascarpone and a variety of cheeses.  

Add in herbs or spices for added flavor (without added carbs), mix together, then pour into your casserole baking dish and you have a whole meal that was super easy to put together!

And who said casseroles are just for lunch or dinner? A Keto breakfast casserole is a great way to start the weekend or to feed a crowd. And leftovers make a quick and easy breakfast during the week.

How to Freeze Casseroles

• Freezing temperatures can cause the material some containers are made of to crack, so always make sure you use freezer safe containers when freezing your leftovers.

• To help prevent freezer burn, allow your casserole to completely cool before moving it to the freezer.

• Be sure to use a permanent marker to label the outside of the casserole packaging to include the date you cooked it and the contents of the package.

• If you’re making entrées to freeze, you can use disposable tin pans. This frees up your nicer casserole dishes and makes it easier to carry for potlucks, you can just take it and leave it!

• To thaw, leave your frozen casserole in the refrigerator overnight. If it’s still slightly frozen, cook on a lower temperature, covered. A good rule of thumb is 350F for half the time you originally baked it.

• Though most casseroles freeze very well, you should check for signs of freezer burn before reheating.

• If you have boiled chicken for your casserole, save the broth! You can freeze it and use it in soups.

I hope these easy Keto Casserole Recipes have inspired you!
