How to Make Low Carb Cauliflower Pizza Casserole
Start by preheating your oven to 375°F (190°C) and lightly greasing a baking dish.
Steam or boil the cauliflower florets for about 5 minutes until they are slightly tender. Drain well and set aside.
In a skillet over medium heat, cook the ground beef or sausage with the diced onion until the meat is browned and fully cooked. Drain any excess grease.
Add the diced bell peppers, garlic powder, Italian seasoning, salt, and black pepper to the skillet and cook for another 2–3 minutes.
Spread the cooked cauliflower evenly in the baking dish.
Pour the meat mixture over the cauliflower and spread it evenly.
Add the pizza sauce over the meat layer and gently spread it.
Sprinkle the mozzarella and cheddar cheese evenly on top.
Bake for 20–25 minutes, or until the cheese is melted and bubbly with a light golden color.
Let the casserole rest for about 5 minutes before serving.
