4. Season the Mixture
Sprinkle salt, pepper, paprika, and Italian seasoning over the beef and vegetable mixture. Mix thoroughly to combine all the flavors.
5. Prepare the Cheese Sauce
In a small saucepan over medium heat, melt the butter. Stir in the flour and cook for 1–2 minutes to form a roux. Gradually whisk in the milk until the sauce thickens, about 3–4 minutes. Remove from heat and stir in ½ cup of shredded cheddar cheese until melted.
6. Combine Pasta and Beef
In a large mixing bowl, combine the cooked pasta and beef-vegetable mixture. Pour the cheese sauce over the top and stir until everything is evenly coated.
7. Assemble the Casserole
Transfer the mixture into your prepared baking dish. Sprinkle the remaining shredded cheese and Parmesan evenly over the top for a golden, bubbly crust.
8. Bake to Perfection
Place the casserole in the preheated oven and bake for 20–25 minutes, or until the cheese is melted and slightly browned. For extra crispiness, broil the top for 1–2 minutes at the end.
9. Serve and Enjoy
Let the casserole cool for 5 minutes before serving. This allows the flavors to meld together and makes it easier to slice. Pair with a fresh green salad or garlic bread for a complete meal.
