🥩 Ingredients

Main Ingredients:

  • 1 lb (450g) ground beef or thinly sliced steak
  • 1 medium onion, chopped
  • 1 green bell pepper, diced
  • 1 red bell pepper, diced (optional, for sweetness and color)
  • 8 oz (225g) mushrooms, sliced
  • 2 cloves garlic, minced
  • Salt and black pepper, to taste
  • 1 tsp Worcestershire sauce
  • 1 tsp Italian seasoning
  • 4 oz (115g) cream cheese, softened
  • 1 cup (240ml) heavy cream or milk
  • 1 ½ cups (170g) shredded provolone or mozzarella cheese (or a mix)
  • 2 eggs
  • 2 cups cooked pasta (elbow, penne, or rotini — optional for a heartier casserole)

👩‍🍳 Instructions

Step 1: Cook the Beef and Veggies

  1. Preheat your oven to 375°F (190°C).
  2. In a large skillet, cook ground beef (or sliced steak) over medium heat until browned. Drain excess fat.
  3. Add onion, bell peppers, mushrooms, and garlic. Cook for about 5–7 minutes, until veggies soften.
  4. Season with salt, pepper, Worcestershire sauce, and Italian seasoning. Stir well.

Step 2: Make the Creamy Base

  1. Reduce heat to low and stir in cream cheese until melted and creamy.
  2. Add heavy cream (or milk) and half of the shredded cheese. Stir until smooth and well combined.
  3. If using pasta, fold it in now until evenly coated.

Step 3: Assemble the Casserole

  1. Transfer the mixture to a greased 9×13-inch (23×33 cm) baking dish.
  2. In a small bowl, whisk the eggs and pour evenly over the beef mixture (this helps it set).
  3. Sprinkle the remaining cheese on top.

Step 4: Bake

  1. Bake uncovered for 20–25 minutes, or until bubbly and golden on top.
  2. Let rest for 5–10 minutes before serving.
