The Best Keto Casserole Recipes for Meal Prep & Families

Whether it’s an informal gathering or kid-friendly, family dinner, sometimes we just need easy meal ideas! And, these Low Carb Keto Casserole recipes fit the bill. Most of these dishes require just a few ingredients and minimal prep, making them perfect for those who don’t want to (or can’t) spend all day cooking. 

Why make keto casseroles?

If you’re cooking for a crowd, or you just had a busy week, casseroles are a great time saver, especially for those who tend to do keto meal prep planning. For the most part, you can make a casserole in one pan and there is usually more than enough to have dinner for at least two days. 

Besides being great for saving time, they are also great freezer meals. Since casseroles have meat, veggies, and a good amount of other things like cheese to hold them together, you can always freeze these and reheat them without worrying about taste and flavor. 

What to serve with these low carb casseroles recipes:

Since keto casseroles are usually quite rich, all you need to do is pair them with a salad. I tend to gather up my favorite lettuce and top them with any of these low-carb salad dressing recipes. 

You might also add any of these low carb side dishes to your plate. Just make sure you find a nice balance of carbs, fat, and protein.
