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:

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 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.
