Instructions
Preparation
- Heat the oven to 375°F and lightly grease a 9x13 baking dish.
- Warm the olive oil in a large skillet over medium-high heat. Add the onion and peppers, cooking until softened and fragrant, about 6 to 8 minutes.
- Stir in the mushrooms and cook for an additional 3 minutes. Add garlic for the last 30 seconds of cooking to avoid burning it.
- Push the vegetables to the edges of the skillet, add the beef in a single layer, and sprinkle with salt, pepper, paprika, and Italian seasoning. Sear for 1-2 minutes per side until pink fades.
- In a bowl, whisk together milk and cornstarch until smooth, then stir in cream cheese until creamy.
- Pour the milk mixture over the steak and vegetables in the skillet; it will thicken while baking.
- If desired, fold in cooked noodles or rice, then taste and adjust seasoning.
- Transfer the mixture into the prepared baking dish, top with provolone and cheddar cheese.
- Bake for 15-18 minutes until the cheese is bubbling and golden at the edges. Let rest for 5 minutes before slicing.
- Garnish with fresh parsley before serving.

Note
Thinly slice the beef for best results. Avoid overcooking to keep it tender. Resting the casserole before serving helps it set for cleaner slices.
