Ingredients Equipment Method Notes

Ingredients
  

  • 2 lbs ground beef 80/20 recommended
  • 1/2 cup chopped onion
  • 4 oz cream cheese softened
  • 1.5 cups sugar-free marinara sauce divided
  • 2 cloves garlic minced
  • 1 tsp dried oregano
  • 1/2 tsp dried basil
  • 1/2 tsp salt or to taste
  • 1/4 tsp black pepper
  • 2 cups shredded mozzarella cheese
  • 1/2 cup pepperoni slices

Equipment

  • 1 9x13 inch baking dish
  • 1 Large Skillet

Method
 

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
  2. In a large skillet over medium-high heat, cook the ground beef and chopped onion until the beef is fully browned. Drain all excess grease from the skillet.
  3. Reduce the heat to low. Add the minced garlic, softened cream cheese, 1/2 cup of the marinara sauce, oregano, basil, salt, and pepper to the skillet. Stir continuously until the cream cheese has melted completely and the sauce is creamy.
  4. Transfer the meat mixture to the prepared baking dish and spread it into an even layer. Pour the remaining 1 cup of marinara sauce over the top.
  5. Sprinkle the shredded mozzarella cheese evenly over the sauce. Arrange the pepperoni slices on top. Bake for 20-25 minutes, until the cheese is melted and bubbly. For crispier pepperoni, broil for 1-2 minutes at the end, watching carefully.
  6. Let the casserole rest for 5-10 minutes before serving. This allows it to set and makes for cleaner slices.

Notes

Tip 1: For the best flavor and melt, use a block of whole milk mozzarella and shred it yourself.
Tip 2: Ensure you are using a sugar-free marinara sauce to keep the recipe keto-friendly. Check the nutrition label for hidden sugars.
Tip 3: Feel free to add other low-carb pizza toppings like cooked mushrooms, black olives, or bell peppers.
