Ingredients
Main Ingredients
- 1 lb (450 g) ground beef (or shaved steak)
- 1 tbsp olive oil
- 1 medium onion, diced
- 1 green bell pepper, diced
- 1 red bell pepper, diced
- 8 oz (225 g) white mushrooms, sliced
- 2 cloves garlic, minced
- 1 tsp salt (adjust to taste)
- ½ tsp black pepper
- 1 tsp Worcestershire sauce
- 8 oz (225 g) cream cheese, softened
- ½ cup (120 ml) beef broth
- 1 cup (115 g) shredded mozzarella cheese
- 1 cup (115 g) shredded provolone cheese
- ½ tsp dried oregano
Optional Garnish
- Chopped parsley
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
- Cook Meat: In a large skillet over medium-high heat, add olive oil and cook the ground beef until browned, breaking it apart as it cooks. Drain excess fat if necessary to avoid greasiness.
- Sauté Vegetables: Add diced onion, green and red bell peppers, and sliced mushrooms to the skillet. Sauté the vegetables for 5 to 6 minutes until they soften. Stir in the minced garlic and cook for an additional minute to develop flavor.
- Season & Combine: Stir in salt, black pepper, Worcestershire sauce, and beef broth. Allow the mixture to simmer for 2 to 3 minutes so the flavors meld together.
- Make It Creamy: Lower the heat and stir in the softened cream cheese until it fully melts and combines smoothly with the meat and vegetables, creating a creamy filling.
- Assemble Casserole: Transfer the creamy beef and vegetable mixture into a lightly greased 9×13-inch baking dish. Evenly sprinkle shredded mozzarella, provolone, and dried oregano on top.
- Bake: Place the casserole in the preheated oven and bake uncovered for 15 to 20 minutes, until the cheese on top is melted, bubbly, and slightly golden.
- Serve: Garnish the casserole with chopped parsley if desired. Serve hot alongside crusty bread, over cooked rice, or paired with a fresh side salad for a complete meal.
Notes
- For a lower-fat version, use lean ground beef or substitute with ground turkey or chicken.
- You can add sliced provolone or mozzarella on top before serving for extra cheesiness.
- This casserole can be prepared a day ahead, refrigerated, and baked right before serving.
- Adjust salt and Worcestershire sauce according to your taste preference.
- For a gluten-free option, ensure Worcestershire sauce is gluten-free and serve with gluten-free sides.
