Why Choose Low-Carb Casseroles?

These keto casseroles do what all-in-one dishes do best: get all of the good stuff in there! Most of these recipes are filled with veggies and packed with protein and fat, making them a well-rounded choice for any low-carb meal. Casseroles are amazing because they usually only require one pan, and they’re perfect for meal prepping!

Ingredients for Low-Carb Casseroles

Here are some common ingredients and substitutions for low-carb casseroles:

Crunchy Topping: Most commonly, pork rinds are used as they’re extremely low in carbs and add a perfect crunch.
Thickening Agent: Traditional casseroles often call for flour to thicken the casserole’s sauce. Instead, xanthan gum is often used!
Creaminess: Traditional recipes often use milk or other high-carb dairy products. Heavy cream can be a good alternative.
Protein: These low-carb casseroles can all be made meatless or with various proteins added in.

Meal Prepping with Casseroles

Plan ahead with airtight containers so you can separate leftovers out into portions for easy, ready-to-eat meals! Store in the fridge or freezer, then thaw and reheat in the oven or toaster oven for a healthy, filling meal on the run!

Italian Chicken Meal Prep Casserole

This Italian Chicken Meal Prep Casserole is made with tender chicken, juicy tomatoes, spinach, and Italian seasoning for a family-friendly, low-carb, keto-friendly, and gluten-free meal.

Ingredient Notes

Using white meat is generally a healthier choice for this Italian chicken recipe. This Italian chicken meal prep casserole is a great use for leftover chicken or rotisserie chicken.

Preparation Instructions

Preheat oven to 350F and oil casserole dish/meal prep container.
Toss chicken in sour cream or mayo. Mix in Italian seasoning.
Next, layer zucchini and spinach at the bottom of the casserole dish. Save extra spinach for top.
Lastly, spoon diced tomatoes on top of the chicken. If desired, add grated Parmesan to top of casserole.
Bake at 350F for 25-30 minutes or until top is golden brown.

Ingredient Selection

Cooked chicken: Any pre-cooked chicken will work here.
Heavy whipping cream: As long as you use heavy cream, you don’t need flour or cream cheese to thicken the sauce.
Parmesan: Parmesan gives the cream sauce a pungent bite and makes it more like a traditional Alfredo.

Cooking Instructions

Sauté the broccoli: Melt some of the butter in an oven-safe skillet, and then sauté the broccoli until bright green and just tender. Remove the broccoli to a bowl.
Make the sauce: Melt more butter in the pan then sauté the garlic until fragrant. Add the cream and bring to a simmer, then cook until reduced and thickened, 3 to 5 minutes.
Add the cheese: Stir in 1/3 cup of the mozzarella and all of the Parmesan until melted. Season with salt and pepper to taste.
Stir in the broccoli and the chicken and top with the remaining 1 cup of mozzarella cheese.
Preheat the broiler and broil until cheese is melted and browned.

Tips and Variations

Use an ovenproof skillet: This is a recipe that goes straight from stovetop to oven, so that you don’t have to transfer the mixture to a casserole dish.
Use plenty of broccoli: Put in a full 16 ounces, which is closer to 3 cups chopped.
Subbing frozen broccoli: If you want to use frozen broccoli, you won’t even need to cook it. Let it thaw completely, then skip to Step 2 and make the sauce.
What kind of chicken works best? Use cooked boneless, skinless chicken for this casserole. I like to use chicken thighs for their richer flavor, but breasts work as well. If using rotisserie chicken, remove the skin and bones.

Storage Information

Store any leftovers in a covered container in the fridge for up to 5 days. It reheats well in the microwave or in the oven.
