Ingredients

Scale

Meat and Vegetables

  • 1 lb ground beef
  • 1 medium onion, diced
  • 2 cloves garlic, minced
  • 1 cup bell peppers, diced (or other low-carb vegetables)

Sauce and Seasoning

  • 1 cup tomato sauce (no sugar added)
  • 1 teaspoon Italian seasoning

Cheese

  • 1 to 1 ½ cups shredded mozzarella or cheddar cheese

Instructions

  1. Brown the Ground Beef: In a large skillet over medium heat, cook the ground beef, diced onion, and minced garlic until the beef is browned and the onions are translucent, about 7-10 minutes. Drain any excess fat.
  2. Add Vegetables and Sauce: Stir in the diced bell peppers and tomato sauce along with the Italian seasoning. Simmer the mixture on low heat until the sauce thickens slightly, about 5-7 minutes, stirring occasionally.
  3. Prepare the Casserole: Preheat your oven to 375°F (190°C). Spread the beef and vegetable mixture evenly in a casserole dish.
  4. Top with Cheese: Generously sprinkle shredded mozzarella or cheddar cheese over the top of the beef mixture.
  5. Bake to Finish: Place the casserole dish in the preheated oven and bake for 15-20 minutes, or until the cheese is fully melted, bubbly, and slightly golden on top.
  6. Serve: Remove from the oven and let cool for a few minutes before serving. Enjoy your keto-friendly, cheesy ground beef casserole!

Notes

  • You can substitute bell peppers with other keto-friendly vegetables like zucchini or mushrooms.

  • For added flavor, sprinkle some crushed red pepper flakes or additional herbs when cooking.
  • Leftovers store well in the refrigerator for up to 3 days and reheat easily.
  • Make sure to drain excess fat from the ground beef to keep the casserole from becoming greasy.
