This combines the flavors of creamy casseroles with the flavors of chicken parmesan. It is one of our favorite easy dinners. Give my Keto Pizza Casserole a try. I’m sure your family will love it too! 

My family loves casseroles, and they are so easy. When we ate this for dinner, I got a couple of “Mom, this is good!” and “Can I have seconds?”

Ingredients

You only need five ingredients to make this easy keto pizza casserole.

• Cooked Chicken – Use leftover chicken, shredded chicken, or a store-bought rotisserie chicken to save time.
• Cream Cheese – Creates the creamy layer that makes this casserole so delicious.
• Garlic – Adds flavor to the cream cheese mixture.
• Marinara Sauce – Choose your favorite sugar-free marinara sauce.
• Mozzarella Cheese – Shredded mozzarella melts into that ooey-gooey cheese topping.

See recipe card for quantities.

How To Make Keto Pizza Casserole

Step One: Add the cooked chicken to the bottom of a casserole dish. Mix the cream cheese and garlic, then spread the mixture over the chicken. Top with marinara sauce.

Step Two: Cover with shredded mozzarella cheese.

Step Three: Bake until the cheese is golden and bubbly. Serve and enjoy!

Substitutions

• Chicken – If you don’t have precooked chicken already, feel free to cook up boneless chicken how you like. I have made Instant Pot Shredded Chicken and just saved some back to use for this recipe later. Or hit up your local store for a rotisserie chicken that you can shred and use.
• Ground Meat – You can substitute ground turkey, ground chicken, or even ground beef. Just cook up the meat until fully cooked, lay it in the bottom of the dish, then add in your layers and bake. I would season the ground meat with a little salt and pepper for added flavor.
• Marinara Sauce – You can use any of your favorite brands of marinara sauce or make your own Keto Marinara Sauce. Just look for a sauce that doesn’t have added sugar. You could even buy a vodka sauce to use in place of marinara sauce.

I generally buy what is on sale for the week. So feel free to purchase your favorite low carb marinara sauce.

Variations

I really wanted to keep this basic and simple, but of course, you can add your favorite pizza toppings!

• Add Veggies: If you want to add in some diced onions, peppers, mushrooms, or olives, just lay them over the chicken. Then follow up with the cream cheese layer and marinara. Then bake like normal.
• Add Pepperoni: I like to put the pepperoni on top and then sprinkle a tiny bit of the cheese over it to hold it on.
• Add Sausage: Just add some browned ground Italian sausage on top of the chicken before adding the sauce and cheese.

Equipment

All you need is a casserole dish, a mixing bowl, and a spoon or spatula for spreading the cream cheese mixture.

Storage

Store leftover keto pizza casserole in an airtight container in the refrigerator for up to 3-4 days.

I will either toss it in the microwave for a quick reheat, or if we are doing this for leftovers the next night, I will take the leftovers and cover them with aluminum foil and heat them in the oven. That way it tastes like the first night.

This also is great for prepping meals for the week. Whether you take your lunch each day to work or want quick dinners to reheat, this low carb casserole heats nicely. I use this often for ready-to-reheat meals on busy weekdays when I don’t have time to cook a full lunch.

Freezing: Because of the cream cheese layer, it could curdle during the thawing of the dish. If you do freeze this casserole, note that it most likely will change in texture.

If you do opt to freeze it, place it in a freezer-friendly container and store for up to three months. Thaw in the fridge the night before and then warm up in the oven until heated all the way through.

Common Questions

Can I Make Pizza Casserole Ahead of Time?

Yes! You can prep your low carb pizza casserole the morning of the day you want to bake it. Just prep in the morning, cover and place in the fridge until you are ready to cook it. Only allow a bit more time during the cooking process as the pan will be chilled from the refrigerator.

What Should I Serve with Keto Pizza Casserole?

Most of the time I pair this with a chopped salad or green vegetables. I served it with frozen steam-in-bag broccoli. You could also do a cloud bread with some herbs sprinkled over the top to give it an Italian flair.

This recipe is so simple to make, and I think you all will enjoy it if you like the ingredients used. Next time you are craving something a bit different for dinner, give this casserole a try!
