Main Ingredients

  • 1 pound ground beef Use lean for less splatter; 80/20 works for richer flavor.
  • 1 cup beef pepperoni slices
  • 2 cups cauliflower rice Store-bought or homemade.
  • 2 cups shredded mozzarella cheese 1 cup for mixing, 1 cup for topping.
  • 1 cup marinara sauce Pick a no-sugar-added brand for lower carbs.
  • 1 teaspoon Italian seasoning
  • Salt To taste.
  • Black pepper To taste.

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C).
  • Heat a large skillet over medium. Add the ground beef and cook, breaking it apart, until fully browned.
  • Drain excess fat from the skillet. Return to heat and stir in the marinara sauce and Italian seasoning. Season with salt and black pepper to taste.
  • Add the cauliflower rice to the saucy beef and stir until evenly combined. Fold in half of the shredded mozzarella so it starts to melt into the mix.
  • Transfer the mixture into a lightly oiled 9x9-inch (similar) baking dish and spread it into an even layer.
  • Sprinkle the remaining mozzarella over the top, then arrange the beef pepperoni slices evenly.

Baking

  • Bake for 25–30 minutes, until the cheese is bubbly and edges are golden.
  • Let the casserole rest for 5 minutes before cutting and serving—this helps it set so portions hold together.

Notes

For a lighter protein, you can swap ground beef for ground turkey or chicken. Also, for a dairy-free option, try shredded dairy-free cheese and omit or replace mozzarella with a creamy cashew sauce.
