If just thinking about casseroles brings your mother’s famous green bean or tuna noodle creations to mind, you should know these one-dish wonders have come a long way since then.
Casseroles are no longer an excuse to clean out the fridge and somehow pull together an easy, tasty meal in under an hour.
With this roundup of low-carb casseroles, you won’t have to waste time reworking your old recipes to fit your new keto meal plan.
Why You Should Make at Least One Low-Carb Casserole Every Week
Casseroles are a dream if you have a busy lifestyle and still want to stick to a ketogenic diet.
Why? Because they’re so incredibly easy to make. Even if you lack cooking skills and are just starting out with low-carb cooking, you can make a casserole.
Simply preheat your oven, take a bunch of healthy ingredients, pop them into a casserole dish, and then bake away while delicious aromas fill your home.
Like Crockpot and Instant Pot recipes, casseroles take zero practice to get them right. You can even have your kids help to make things easier and cut prep time in half.
Casseroles are also ideal for keto meal prep. They’re so easy and fast, you can whip up a few different casseroles in one day and have your whole week’s worth of meals ready to go without repeating flavors.
Casseroles can be used for breakfast, lunch, dinner, and even as a low-carb side dish. You can make one for any meal of the day and to suit all sorts of picky palates. Plus, you can sneak lots of healthy ingredients in every bite.
While your old casserole recipes and store-bought options have way more carbs, hidden sugars, and questionable ingredients, every recipe on this list of low-carb casseroles uses whole-foods ingredients to help you stay on track with your ketogenic diet and maybe even improve your health.
