Instructions

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil.
Add pasta and cook until al dente according to package instructions.
Drain and set aside.

Step 2: Sauté the Beef and Veggies

Heat olive oil in a large skillet over medium-high heat.
Add sliced beef and sear for 2-3 minutes until browned but not overcooked. Remove and set aside.
In the same skillet, add onions and bell peppers. Cook for 4-5 minutes until softened.
Stir in garlic, Italian seasoning, salt, and pepper. Cook for another 1-2 minutes.
Return beef to the skillet, mix well, and remove from heat.

Step 3: Make the Cheese Sauce

In a saucepan, melt butter over medium heat.
Whisk in flour and cook for 1 minute to form a roux.
Slowly whisk in milk and beef broth. Bring to a gentle simmer and cook until slightly thickened, about 3-4 minutes.
Stir in provolone, mozzarella, and Parmesan until melted and smooth.

Step 4: Assemble the Pasta Bake

Preheat oven to 375°F (190°C).
In a large mixing bowl, combine cooked pasta, beef and vegetable mixture, and cheese sauce. Mix well.
Transfer mixture to a greased 9×13 inch baking dish.
Sprinkle the remaining provolone and mozzarella on top.

Step 5: Bake and Serve

Bake uncovered for 20-25 minutes, or until bubbly and golden on top.
Let rest for 5 minutes before serving.
Garnish with chopped parsley if desired.

Notes

Use Good Quality Beef – Thinly sliced sirloin gives the best texture and flavor.
Don’t Overcook the Beef – It will continue cooking in the oven, so sear quickly.
Balance the Sauce – If the sauce is too thick, thin it with a little extra milk.
Let It Rest – Resting before serving helps everything set and makes it easier to slice.
Add Crunch – Top with a sprinkle of breadcrumbs mixed with melted butter for a crispy topping.
