How to Make Low Carb Pizza Casserole
Preheat Oven: Set your oven to 375 °F (190 °C). While it s heating up, grease a 9 13-inch baking dish to prevent sticking and prepare your ingredients.
Brown the Meat: In a skillet over medium-high heat, brown the ground beef until it s fully cooked and no longer pink. Remember to break it up into small pieces as it cooks. Drain any excess fat for a leaner dish.
Saut Vegetables: Add diced onion and bell peppers to the skillet with the beef. Saut for about 5-7 minutes, just until they re softened and fragrant. This step really builds flavor!
Add Mushrooms and Garlic: Stir in the sliced mushrooms and cook for another 5-8 minutes until they re nicely browned. Then, throw in the minced garlic, cooking for an additional minute until it becomes fragrant.
Mix in the Sauce: Combine the cooked beef and vegetable mixture with crushed tomatoes, low-carb marinara sauce, tomato paste, and all the seasoning (oregano, basil, onion powder, garlic powder, red pepper flakes, and Italian seasoning). Let this simmer for 5-10 minutes for the flavors to meld.
Layer Meat Mixture: In the greased baking dish, layer half of the meat mixture evenly across the bottom, followed by half of the shredded mozzarella and Parmesan cheese.
Repeat Layers: Layer the remaining meat mixture over the cheese and top with the rest of the mozzarella, Parmesan, pepperoni, and black olives for extra flavor.
Bake Covered: Cover the baking dish with aluminum foil and bake for 20 minutes. After that, remove the foil and continue baking for an additional 15-20 minutes until the top is golden brown and bubbling.
Rest and Garnish: Once baked, allow the casserole to rest for 10-15 minutes. This resting period helps it set, making it easier to cut. Just before serving, sprinkle freshly chopped parsley or basil for a lovely touch!
Optional: Serve with a light salad to balance the richness of the casserole.
