How to Make Crock Pot Low Carb Pizza Casserole Recipe
Step 1: Brown the Meats
Start by heating a skillet over medium heat and browning both the ground beef and Italian sausage. This step develops deep, savory flavors and ensures your meats are perfectly cooked before going into the crock pot.
Step 2: Drain Excess Fat and Transfer
Once browned, carefully drain any excess fat to keep your casserole from becoming too greasy. Then, transfer the meat mixture into your crock pot to set the foundation for your casserole.
Step 3: Add the Fresh and Flavorful Veggies
Next, toss in your pepperoni slices, diced bell peppers, and onions along with the rich low-carb pizza sauce. These ingredients add layers of texture and taste that keep each bite exciting.
Step 4: Season and Stir
Sprinkle in the Italian seasoning, salt, and pepper, then stir everything together well. This distributes the flavors evenly so each mouthful bursts with that classic pizza vibe.
Step 5: Top with Mozzarella Cheese
Generously cover the casserole with shredded mozzarella cheese. This will melt beautifully during cooking, creating a bubbly, irresistible golden layer on top.
Step 6: Slow Cook to Perfection
Cover your crock pot and cook on low for 4-6 hours. The slow cooking allows all the flavors to marry, melding into a hearty, comforting dish you’ll want to savor slowly.
Step 7: Serve and Enjoy
When done, give the casserole a gentle stir, serve it hot, and enjoy the ultimate combination of pizza flavors without the carb overload.
