Ingredients

Scale

Ground Beef Mixture

  • 1 lb ground beef
  • 1 medium onion, diced
  • 2 cloves garlic, minced
  • 1 cup bell peppers, diced (or other low-carb veggies)
  • 1 cup tomato sauce
  • 1 tsp Italian seasoning

Topping

  • 1 to 1 1/2 cups shredded mozzarella or cheddar cheese

Instructions

  1. Brown the Ground Beef: In a large skillet over medium heat, cook the ground beef along with diced onion and minced garlic. Stir occasionally until the beef is fully browned and the onions are translucent, about 6-8 minutes. Drain any excess fat.
  2. Add Vegetables and Tomato Sauce: Stir in the diced bell peppers (or other low-carb vegetables), tomato sauce, and Italian seasoning. Reduce the heat and let the mixture simmer gently until the sauce thickens slightly and the vegetables soften, about 8-10 minutes.
  3. Assemble the Casserole: Preheat the oven to 375°F (190°C). Transfer the meat and vegetable mixture evenly into a casserole dish. Spread it out to form an even layer.
  4. Add Cheese Topping and Bake: Sprinkle the shredded mozzarella or cheddar cheese evenly over the top of the mixture. Place the casserole in the preheated oven and bake until the cheese is melted, bubbly, and slightly golden, about 15-20 minutes.
  5. Serve: Remove from the oven and let the casserole rest for 5 minutes before serving. Enjoy this keto-friendly casserole warm for a comforting low-carb meal.

Notes

  • You can substitute bell peppers with other keto-friendly vegetables like zucchini or mushrooms.
  • Using full-fat cheese helps keep the dish creamy and adds richness.
  • Make sure to drain excess grease after browning the beef for a less greasy casserole.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
  • For extra spice, add red pepper flakes when cooking the beef.
