Here’s what you’ll need to make this delicious keto pizza casserole:

Base Layer:

1 lb ground Italian sausage
1 lb ground beef
1 small onion, diced
2 cloves garlic, minced

For the Casserole:

1 ½ cups sugar-free marinara sauce (like Rao’s or homemade)
1 ½ cups shredded mozzarella cheese
1 cup shredded cheddar cheese
½ cup sliced pepperoni
½ cup sliced mushrooms
½ cup diced bell peppers
¼ cup black olives, sliced (optional)
1 tsp Italian seasoning
¼ tsp red pepper flakes (optional, for heat)

Instructions

Preheat the Oven

Preheat your oven to 375°F (190°C). Grease a 9×13-inch casserole dish or line it with parchment paper for easy cleanup.

Cook the Meat

Heat a large skillet over medium heat. Add the ground sausage, ground beef, and diced onion.
Cook until the meat is browned and the onion is softened, about 7–10 minutes. Drain any excess grease.
Add the minced garlic and cook for another 1–2 minutes until fragrant.

Assemble the Casserole

Spread the cooked meat mixture evenly in the bottom of the prepared casserole dish.
Pour the sugar-free marinara sauce over the meat and spread it evenly.
Sprinkle half of the shredded mozzarella and cheddar cheese over the sauce.

Add Toppings

Layer the sliced pepperoni, mushrooms, bell peppers, and olives on top of the cheese.
Sprinkle the remaining mozzarella and cheddar cheese over the toppings.
Add Italian seasoning and red pepper flakes (if using) for extra flavor.

Bake

Bake in the preheated oven for 20–25 minutes, or until the cheese is melted and bubbly.

Step 6: Serve and Enjoy

Let the casserole cool for 5 minutes before serving. Slice into portions and enjoy with your favorite keto sides or salads.

Tips for Success

Choose Quality Marinara: Look for a sugar-free marinara sauce to keep the carb count low.
Pre-Cook Veggies: If you like your vegetables softer, sauté them for a few minutes before adding them to the casserole.
Experiment with Toppings: Add cooked bacon, spinach, or jalapeños for a personalized touch.
