Keto Low Carb Pizza Casserole: Ultimate Deep Dish Bake (6 Net Carbs!)

Instructions:

1. Preheat the oven to 375°F (190°C). Lightly grease the 9x13 inch casserole dish.
2. Heat the olive oil in the large skillet over medium-high heat. Add the ground beef and Italian sausage. Break up the meat and cook until fully browned (about 8 minutes).
3. Season the meat generously with salt, pepper, oregano, and garlic powder. Cook for 1 minute more. Crucially, drain off any excess fat into a heatproof container.
4. Press the seasoned meat mixture firmly and evenly into the bottom of the prepared casserole dish. This acts as your 'crust'.
5. Return the same skillet to medium heat. Add the diced onion, mushrooms, and bell pepper. Sauté for 5-7 minutes until the vegetables have softened slightly and released some moisture.
6. Pour 1 cup (240 ml) of the low-carb marinara sauce evenly over the meat base layer in the dish.
7. Spoon the sautéed vegetables over the sauce layer.
8. Drizzle the remaining 1 cup (240 ml) of marinara sauce evenly over the vegetables, ensuring everything is lightly coated. Sprinkle with dried basil.
9. Sprinkle 2 cups of the shredded mozzarella evenly over the sauced vegetables.
10. Place the casserole dish in the preheated oven. Bake for 20 minutes, or until the sauce is bubbly around the edges and the cheese is melted.
11. Remove the casserole from the oven. Arrange the pepperoni slices on top. Sprinkle with the remaining 1/2 cup of mozzarella, the Parmesan cheese, and a pinch of red pepper flakes (if using).
12. Return the dish to the oven and bake for another 10–15 minutes, or until the cheese is golden brown and deeply bubbly.
13. Remove the casserole from the oven and let it rest for 10 minutes. This is essential for the layers to settle.
14. Slice into 6 squares and serve hot.
