This keto pizza casserole has all the best parts of a pizza baked together, creating the ultimate low-carb comfort food. It’s cheesy, meaty, and made with five ingredients.
We love all things low-carb pizza! Hello keto pizza, pizza bowls, and, more recently, keto pizza casserole. Rather than piling our toppings on a keto pizza crust, everything’s layered on a bed of low-carb pasta or cauliflower and baked until the cheese is bubbly and golden brown.
It’s one of my favorite dishes to make when we’re hosting since it’s full of delicious flavors everyone will love, yet it’s deceptively low in carbs.

★★★★★ REVIEW
“I’ve tried this with cauliflower and your low-carb pasta, and it is delicious. Even my non-keto family are huge fans of it“.- Sabrina
Key Ingredients
- Cauliflower OR keto pasta. I’ve tested this recipe with seasoned steamed cauliflower and homemade keto pasta. Both work well, but it depends on how much time you want to put to this. The carbs aren’t all that different either!
- Pizza sauce. Homemade keto pizza sauce, not any store-bought ones full of sugar and unnecessary carbs! You can also use my pomodoro sauce or sugo.
- Parmesan and mozzarella cheese. A combination of both kinds of cheese yields stretchy and melted cheese.
- Pepperoni. Simple and classic pizza topping.

Pizza casserole variations
- Lower the carbs. Use half the pasta and double up on the sauce.
- Add more protein. For a heartier casserole, add shredded chicken, bacon, or diced ham.
- Add more low-carb veggies. Like sliced green bell peppers, mushrooms, diced tomatoes, black olives, or spinach.
- Make it spicy. If you can handle the heat, add a few dashes of red pepper flakes to the sauce.
- Make a creamy red sauce. When I really want to go the extra mile, I’ll fold in ½ cup of cream cheese for a more decadent sauce.
