1. Cook the Steak & Veggies
Preheat oven to 375°F (190°C).
Heat oil in a skillet over high heat. Sear steak in batches until browned (2 mins per side), then set aside.
In the same pan, sauté peppers, onions, mushrooms (if using), and garlic until caramelized (8-10 mins).
Stir in Worcestershire sauce, paprika, salt, and pepper.
2. Assemble the Casserole
In a greased 9x13-inch baking dish, layer:
Cooked pasta
Steak & veggie mixture
Provolone + mozzarella
3. Bake to Bubbly Perfection
Bake 15-20 minutes until cheese melts.
Broil 2-3 minutes for a golden top (watch closely!).
4. Serve & Devour!
Garnish with parsley and serve with crusty bread or a side salad.
