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!
Top Tip💡
This recipe takes about five minutes to prep. It is a go-to recipe for those perfect fall days when my family and I want to be outdoors enjoying the season instead of being inside.
Having cooked chicken ready to go is what makes this recipe so quick. I like to cook extra chicken ahead of time and save some for easy casseroles like this one.
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!

How much of the casserole is one serving. This is where I get confused. Don’t want to eat too much . Thanks
1/6th
for the Macros, I need to bring the protein amount down, any suggestions, I have trouble in that area.
I would replace some of the chicken with low carb vegetables as a filler. Cauliflower, broccoli, etc. would be good in this.
I made this today, and did the cream cheese with Italian cheese in the skillet. I then put it over the rotisserie chicken. I added pepperoni and bacon as additional toppings. Do you think it will turn out ok by melting the cream cheese in a skillet to get a sauce type consistency?
Yup! Enjoy 🙂
I’m having a hard time finding a pasta or pizza
sauce with no sugar added. Suggestions?
Classico Roasted Garlic, Raos, and the fancy Walmart Italian brand (it’s their label) are all added sugar free last time I checked. They have natural sugars from the tomatoes but do not add sugar.
I found one at Aldi’s too.
Or make your own! We ended up making so much from a cauliflower pizza recipe we tried, so I am continuously finding recipes that call for sauce. 😂
I love making casseroles. With just two of us there is always enough for dinner for at least two nights – score! This was so easy and quick to fix and tasted great. My husband said it is a keeper. Taryn – seriously – you asked at the beginning of your post ‘who puts chicken on pizza’? BBQ chicken pizza is one of my all time favorites! I’m thinking that this would also be great with a low-carb BBQ sauce in place of the pizza sauce and a few pieces of red onion (standard on BBQ chicken pizza in my area).
Oh yeah!!! BBQ chicken pizza was the first thing that popped into my head when I saw this recipe 👍
Where can I find the recipe for the vodka sauce?
I don’t have a recipe for vodka sauce on my blog but most jarred vodka sauces are low carb.
Can you make this with raw chicken breasts like your Easy Cheesy Bacon Chicken? If so, would it be the same cooking temp and time as that recipe, assuming you cut it thin?
Yes, but I would parcook the chicken and drain the cooking liquid before adding the other ingredients so the sauce isn’t too thin.
I noticed you do not have the amount per serving listed. How does one know how many servings can be eaten in a meal without going over your macros?
The number of servings per recipe is at the top of every recipe card. The nutrition is always for one serving. Here is an example:
Wow! Five ingredients and no breading or pasta! An Italian-ish dish that is lower in carbs! Must make this soon!
This recipe was great. I added green peppers and red onion. I used the vodka sauce. I was worried the marinara sauce my husband would think too tomatoe-y. It was sooooooo good. The only thing I’d change was more red onions and cut the chicken it to much smaller pieces.
This was so quick & easy. It’s super delicious! I threw green peppers, mushrooms, onions and pepperoni on top of the chicken!
This is great! If it were up to my kids they would eat pizza every single night! This is a perfect guiltless meal to add to my meal plan that my whole family will enjoy.
Did you cook your chicken before?
Carrie I’m glad you asked this question. When I first read your question I thought “How silly, if it was pre
cooked chicken the recipe would definitely state that” But it doesn’t. Then looking at the prep photos it is clear that the chicken is precooked. I was ready to make it when I noticed your question. Thanks again for posting.
Sorry for the confusion! When I switched to a new recipe card there was a typo. This does call for cooked chicken.
Yum!! Pizza is my absolute favorite and it’s what I miss the most eating low carb. Can’t wait to make this!
I’m eating low-carb to get ready for a vacation and this recipe is going on my must try list! It sounds so so good!!
Looks good cant wait to try it.
