Ingredients

Main Ingredients

  • 1 lb (450g) ground beef
  • 1 medium onion, diced
  • 2 cups mushrooms, sliced
  • 2 cloves garlic, minced
  • 1 cup beef broth
  • 1 cup sour cream
  • 1 cup shredded cheddar cheese
  • 1 tablespoon Worcestershire sauce (optional)
  • 1 teaspoon Italian seasoning
  • Salt and pepper to taste

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking the casserole.
  2. Cook Beef: In a large skillet over medium heat, brown the ground beef thoroughly until no longer pink. Drain any excess fat to keep the dish from becoming greasy.
  3. Sauté Vegetables: Add the diced onion, minced garlic, and sliced mushrooms to the skillet with the beef. Cook until the vegetables are tender and fragrant.
  4. Add Liquids and Seasoning: Stir in the beef broth, sour cream, Worcestershire sauce (if using), Italian seasoning, salt, and pepper. Mix everything well to combine the flavors evenly.
  5. Assemble Casserole: Transfer the beef and vegetable mixture into a suitable baking dish. Evenly sprinkle the shredded cheddar cheese on top.
  6. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes, or until the cheese is fully melted, bubbly, and golden.
  7. Serve: Remove from oven and serve hot for a delicious, keto-friendly meal.

Notes

  • You can skip the Worcestershire sauce for a milder flavor or if avoiding added sugars.
  • Use full-fat sour cream for richer taste and better keto macros.
  • For added greens, consider mixing in some chopped spinach or kale before baking.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated well.
  • Make sure to drain the fat from the beef to prevent a greasy casserole.
