25 Delicious Low-Carb Casseroles That Make Keto Easier

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.

The toasted parmesan layer on top also gives this casserole that authentic mac and cheese feel despite the lack of carbs and empty calories.

#2: Keto Tuna Mornay

Thanks to a creamy keto cheese layer on top, the tuna takes a backseat when it comes to flavor. So you get all the benefits of healthy fats without even tasting where they’re coming from (i.e., the tuna).

Brussels sprouts are loaded with healthy fiber so they make an excellent addition to any meal when you’re talking about nutrition. 

This cheesy bacon Brussels sprouts casserole can be whipped up in under 15 minutes and only takes about 30 minutes to cook.

One serving is 14.2g of protein, 27.3g of fat, and only 6g of net carbs so it’s pretty filling and satisfying for a side dish.

#2: Loaded Creamy Cauliflower Casserole

This loaded cauliflower casserole uses sour cream and cheddar cheese as the last recipe, but it also throws in half a cup of mascarpone cheese for an extra layer of creamy goodness.

By adding mascarpone, you’ll have a much closer-to-the-real-thing texture which is as smooth and delicious as creamy mashed potatoes.

#3: Bacon Green Bean Casserole

Say goodbye to the old soppy green bean casseroles of your childhood and say hello to this low-carb bacon green bean version that improves upon the original.

This recipe is a serious upgrade to the wet, soupy casseroles of your past because it adds crunchy pork rinds to replace those supposed-to-be crispy fried onions.
