Ingredients Equipment Method Notes

Ingredients
  

  • 1 lb ground Italian sausage mild or hot
  • 4 oz cream cheese softened
  • 1 cup low-carb marinara sauce no sugar added
  • 1 tsp garlic powder
  • 1/2 tsp onion powder
  • 1 tsp dried oregano
  • 2 cups shredded mozzarella cheese whole-milk
  • 1/2 cup pepperoni slices

Equipment

  • 1 9x9 inch baking dish
  • 1 Large Skillet

Method
 

  1. Preheat your oven to 375°F (190°C). Grease a 9x9 inch baking dish.
  2. In a large skillet over medium-high heat, cook the Italian sausage until browned. Drain off any excess grease.
  3. Reduce heat to low. Stir in the softened cream cheese, marinara sauce, garlic powder, onion powder, and dried oregano until the cream cheese is fully melted and the sauce is smooth.
  4. Pour the sausage mixture into the prepared baking dish and spread evenly.
  5. Top with the shredded mozzarella cheese and arrange the pepperoni slices on top.
  6. Bake for 20-25 minutes, until the cheese is melted and bubbly.
  7. Let the casserole rest for 5-10 minutes before slicing and serving.

Notes

Tip 1: For a non-watery casserole, it's crucial to drain the sausage well and sauté any high-moisture vegetables (like mushrooms) before adding them.
Tip 2: Use full-fat, block mozzarella that you shred yourself for the best melting results. Pre-shredded cheeses often contain anti-caking agents that can affect the texture.
