The ultimate guide to the best keto casseroles is here! I’m sharing 15 keto casserole recipes, plus a full guide and tips on how to make low carb casseroles the whole family will love. It’s everything you need to make keto friendly casseroles all winter long… or anytime of year.
How To Make Keto Friendly Casseroles
No matter what kind of easy keto casseroles you want to make, here is a general guide for how to make a low carb casserole:
- Pre-cook the meat. This step ensures that you don’t end up with mushy keto friendly casseroles! It’s also important to make sure that the meat is cooked to a proper and safe temperature.
- Pre-cook the veggies. You also want to cook the veggies before compiling your keto casserole recipes, to avoid a watery result or uncooked veggies in your casseroles.
- Choose the sauce or seasoning. Once you know what type of easy keto casserole recipe you’re making, you can choose your sauce! Some that I love are marinara, cheese sauce, pesto sauce, and alfredo sauce. Other recipes won’t have a sauce, but will add in flavor through seasonings.
- Assemble the low carb casserole. Next up, your casserole needs to be assembled. I often layer mine – and this will vary a bit – but alternating meat, veggies, and sauce layers will ensure a cheesy casserole that melds together.
Tips For Making Low Carb Casseroles
I have a few simple tips for easy ways to turn your favorite casseroles into keto casseroles. Obviously recipes will vary, but these are the main components that usually need tweaking:
- Replace starchy fillers with vegetables. Cauliflower is the most popular replacement for pasta, rice and potatoes in keto casseroles, but you can use just about any veggie you can think of.
- Always pre-cook vegetables. While you may be able to get away with putting uncooked pasta or rice into certain casseroles, this won’t work well when you replace them with low carb veggies. Vegetables release a lot of moisture, so if you put them in raw, either they will remain raw, your keto friendly casserole will be watery, or even both. Always cook them first.
- Be wary of sauces. Almost every casserole needs sauce to prevent it from being dry. Avoid anything with sugar added, and be careful with store bought sauces that can use flour as a thickener. Tomato-based sauces can be keto friendly, but keep the amount low to moderate, as the carbs in there can add up as well. Conversely, cheesy or cream-based sauces will be lower in carbs provided that they are not thickened with flour.
- Skip or replace breadcrumbs. Since breadcrumbs are not low carb, you’ll need to either avoid them or use a keto friendly alternative. Pork rinds make the crispiest carb-free breadcrumb topping for keto casseroles, but almond flour crumbled with some kind of oil would also work.

How To Make Keto Casseroles Ahead
Easy keto dinner casseroles can be easily made ahead, in fact it’s smart to do so! There are a few different ways you can tackle this:
- Prepare ingredients. Chop any vegetables or ingredients that need to be chopped. This simple step can make things go much quicker when it’s time to assemble your casserole.
- Pre-cook ingredients that need to be cooked before assembling the casserole. Some recipes will call for cooking meat or roasting veggies. Do this ahead, and they’ll be ready to use when it’s time to assemble the dish.
- Assemble entire casserole. Assemble the casserole as directed, but before you bake or slow cook it, cover with foil and refrigerate.
- Leftovers. Low carb casserole recipes like this one are easily re-heated. Simply heat in the microwave or 350 degree F oven until heated through.
How To Freeze Low Carb Casserole Recipes
Most keto friendly casseroles freeze really well, which makes them an excellent choice for busy nights.
You can make and assemble the casseroles, but before baking, cover with foil and freeze. When you’re ready-to-bake, thaw overnight in the refrigerator and then bake according to the instructions.
You can also usually bake right from frozen if you prefer, but it will take a long time to heat through, at least half an hour, or longer if it’s also not fully cooked.
