Low Carb Meat Lovers Pizza Casserole Instructions
The complete, printable recipe follows in the recipe card below. In summary:
- Preheat the oven to 400°F (200°C).
- In a medium skillet, brown the ground sausage until fully cooked; set aside.
- Dice the precooked Canadian bacon and set aside with the pepperoni.
- Cut the cauliflower into small florets or pulse in a food processor for a finer texture. Place the cauliflower in a deep casserole dish, drizzle with olive oil, and season with salt, pepper, oregano, onion powder, garlic powder, and rosemary.
- Bake the cauliflower for about 20 minutes, or until tender. Cooking time varies with the size of the pieces.
- Whisk the egg into the marinara sauce to thicken it slightly; this helps the casserole hold together as it bakes.
- Pour the warm cauliflower with the sauce mixture, then sprinkle with half of the shredded mozzarella. Top with the cooked sausage, diced Canadian bacon, and pepperoni. Finish with the remaining mozzarella.
- Bake 10–15 minutes more, until the cheese is melted and lightly browned.
- Remove from the oven and serve warm.
