Ingredients
Scale
Meat and Vegetables
- 1 tablespoon olive oil
- 1 pound thinly sliced beef sirloin
- 1 green bell pepper, sliced
- 1 red bell pepper, sliced
- 1 medium onion, sliced
- 3 cloves garlic, minced
Dairy and Liquids
- 4 ounces cream cheese, softened
- 1/2 cup beef broth
- 6 slices provolone cheese
- 1 cup shredded mozzarella cheese
Seasonings
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
Instructions
- Preheat and prepare dish: Preheat your oven to 375°F (190°C) and lightly grease a 9×13 inch baking dish to prevent sticking and ensure even baking.
- Sauté vegetables: Heat the olive oil in a large skillet over medium heat. Add the sliced onion and bell peppers, cooking for about 5 to 6 minutes until they become soft and slightly caramelized, enhancing their natural sweetness.
- Add garlic: Stir in the minced garlic and cook for an additional 30 seconds or until fragrant, careful not to burn it. Then remove the vegetables from the skillet and set them aside.
- Cook beef: In the same skillet, add the thinly sliced beef sirloin, sprinkle with salt and black pepper, and cook for 4 to 5 minutes until the beef is browned and cooked through, stirring occasionally to break up any clumps.
- Create creamy filling: Return the cooked vegetables to the skillet with the beef. Stir in the softened cream cheese and beef broth, stirring continuously until the mixture is creamy and well combined, forming the savory base for the casserole.
- Assemble casserole: Transfer the beef and vegetable mixture into the prepared baking dish, spreading it out evenly to form the first layer.
- Add cheese layers: Layer the provolone cheese slices evenly over the beef mixture, then sprinkle the shredded mozzarella cheese on top for a gooey, melty finish.
- Bake: Place the casserole in the preheated oven and bake for 15 to 18 minutes, or until the cheeses are completely melted, bubbly, and golden around the edges.
- Rest and serve: Remove the casserole from the oven and let it rest for 5 minutes before serving. This allows the flavors to meld and the dish to set slightly for easier serving.
Notes
- For a spicier version, add sliced jalapeños or a dash of red pepper flakes with the vegetables.
- You can substitute beef sirloin with ribeye or ground beef for different textures.
- If you prefer a creamier casserole, add an extra ounce of cream cheese or a splash of heavy cream.
- This casserole reheats well and can be stored in the refrigerator for up to 3 days.
- Serve with a side of crusty bread or a fresh green salad for a complete meal.
