  • 1/2 cup chopped onion
  • 2 cloves garlic, minced
  • 1 (15 ounce) can marinara sauce, low carb and sugar-free check labels!
  • 1/4 cup heavy cream
  • 1/2 teaspoon dried oregano
  • 1/2 teaspoon dried basil
  • Salt and freshly ground black pepper to taste
  • 4 cups shredded mozzarella cheese divided
  • 1/4 cup grated Parmesan cheese
Optional Toppings

Equipment

  • Large oven-safe skillet or 9x13 inch baking dish

Method
 

  1. Preheat your oven to 375°F (190°C). Find a large oven-safe skillet, preferably cast iron, or a 9x13 inch baking dish.
  2. In your oven-safe skillet over medium-high heat, add the ground Italian sausage. Cook, breaking it up with a spoon, until it's browned and cooked through. Drain off any excess grease.

  3. Add the chopped onion to the skillet with the browned sausage. Cook until the onion is softened and translucent, about 5-7 minutes. Stir in the minced garlic and cook for another minute until fragrant.

  4. Pour in the low-carb marinara sauce. Stir in the heavy cream, dried oregano, and dried basil. Season with salt and freshly ground black pepper to your taste.

  5. Bring the mixture to a gentle simmer. Let it cook for about 5 minutes, allowing the flavors to meld together.
  6. Reduce the heat to low. Stir in 2 cups of the shredded mozzarella cheese and the grated Parmesan cheese until the cheese is melted and well incorporated into the sauce. This creates a rich, creamy base for your Low Carb Keto Crustless Pizza Casserole.

  9. Place the skillet (or transfer the mixture to your baking dish if you didn't use an oven-safe skillet) into the preheated oven.
  10. Bake for 15-20 minutes, or until the cheese on top is melted, bubbly, and lightly golden brown.
  11. Let the Low Carb Keto Crustless Pizza Casserole sit for about 5-10 minutes before serving. This allows it to set up slightly, making it easier to scoop. Serve hot and enjoy your delicious, guilt-free pizza experience!
