If you love pizza but follow a low‑carb or keto lifestyle, this Low Carb Crock Pot Pizza Casserole makes a satisfying weeknight dinner. It’s loaded with savory sausage, plenty of cheese, and classic pizza toppings—without a traditional crust. Made in a casserole‑style slow cooker, it’s convenient, hands‑off, and family friendly.

This recipe was inspired by a crustless pizza casserole cooked in a casserole crock pot.

Using the crock pot keeps the house cool compared with baking in the oven—handy in warm weather.

Crustless Pizza Casserole Ingredients

I like combining ground pork and beef for extra flavor and richness, and I often double the meat for a heartier family meal.

Key components for a flavorful low‑carb pizza casserole:

• Sausage and beef: Ground pork plus ground beef give a great base for a sausage‑style pizza casserole.
• Pizza seasoning: A good pizza or Italian seasoning blend brings classic pizza flavor.
• Pepperoni: Pork or turkey pepperoni works; omit if you prefer.
• Veggies: Onions, peppers, mushrooms, and olives are great additions—use what your family likes.
• Sauce: Low‑carb pizza sauce or unsweetened tomato paste/sauce; season plain sauce if needed.
• Cheese: Plenty of shredded mozzarella or Italian blend—don’t skimp.

How to Make Low‑Carb Pizza in the Casserole Crock Pot

Brown the ground pork and ground beef in a skillet over medium heat, seasoning with pizza seasoning as it cooks. Add diced onions and peppers (or other chosen veggies) to the meat and cook 2–3 minutes to release moisture. Stir in a drained can of diced tomatoes, then transfer the mixture to a casserole crock pot and spread it evenly.

Spoon pizza sauce over the meat, sprinkle shredded mozzarella across the top, and add pepperoni slices. Cover and cook on high for about 2 hours or low for 3–4 hours, until heated through and the cheese is melted and bubbly.

To keep picky eaters happy, place toppings like mushrooms on only part of the casserole rather than mixing them throughout. Kids who help assemble the dish are often more excited to try it.

Tips for Making Crock Pot Low‑Carb Pizza Casserole

• Use the pizza toppings you enjoy—build layers the way you would on a pizza (meat, veggies, sauce, cheese).
• Pre‑cook vegetables to reduce excess liquid during slow cooking.
• If following strict keto, check seasonings and sauces for added sugars.
• Look for ground pork near fresh pork cuts in the grocery meat case if your store doesn’t have it with other ground meats.

How to Store and Reheat

• Storage: Refrigerate leftovers in an airtight container for up to 4 days.
• Reheating: Reheat individual portions in the microwave or warm in an oven set to 350°F until heated through.

This casserole freezes well: cool completely, wrap tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
