Ingredients
  

Ingredients
  • 1 pound ground beef
  • 1 cup pepperoni slices
  • 2 cups cauliflower rice (fresh or frozen, thawed and squeezed dry)
  • 1 cup shredded mozzarella cheese, divided
  • 1 cup marinara sauce (no sugar added)
  • 1 teaspoon Italian seasoning
  • Salt to taste
  • Black pepper to taste

Equipment

  • 9x9 inch baking dish
  • Large skillet

Method
 

Instructions
  1. Preheat your oven to 350°F (175°C). Lightly grease a 9x9 inch or similar-sized baking dish.
  2. In a large skillet, cook the ground beef over medium-high heat until it's nicely browned. Use a spoon to break it apart as it cooks.
  3. Carefully drain off any excess fat from the skillet. Return it to the heat and stir in the marinara sauce, Italian seasoning, salt, and pepper. Let it simmer for a couple of minutes for the flavors to meld.
  4. Turn off the heat and stir in the cauliflower rice and half of the shredded mozzarella cheese. Mix until everything is well combined.
  5. Spread the mixture evenly into your prepared baking dish.
  6. Top the casserole with the remaining mozzarella cheese, spreading it to the edges. Arrange the pepperoni slices over the cheese.
  7. Bake for 25-30 minutes, or until the cheese is completely melted, bubbly, and starting to turn golden brown on top.
  8. Let the casserole cool for about 5-10 minutes before serving. This helps it set up, making it easier to slice and serve.

Notes

To prevent a watery casserole, squeeze as much excess moisture from the cauliflower rice as possible. For a perfect golden-brown topping, use whole-milk mozzarella shredded from a block and consider broiling for the final 1-2 minutes (watch carefully). Season the meat mixture generously to compensate for the mildness of the cauliflower.
