Cook the Pasta: Begin by boiling a large pot of salted water. Once boiling, add 1 lb rigatoni or penne pasta and cook according to package instructions until al dente. Once cooked, drain and set aside.
Cook the Steak: In a large skillet, heat 2 tbsp olive oil over medium-high heat. Season 1 lb thinly sliced steak with salt and black pepper to taste. Add the steak to the skillet and sear for about 2-3 minutes until browned. Remove the steak from the skillet and set aside.
Cook the Veggies: In the same skillet, add an additional 1 tbsp olive oil if needed. Sauté 1 sliced medium onion and 1 sliced green bell pepper and 1 sliced red bell pepper for about 4-5 minutes until softened. Add 2 minced garlic cloves and cook for another 1-2 minutes until fragrant.
Make the Sauce: Return the cooked steak to the skillet. Add 1 tsp Worcestershire sauce and 1 cup beef broth, stirring to combine. Pour in 1 cup heavy cream and let the mixture simmer for 3-4 minutes until thickened slightly, stirring occasionally.
Combine with Pasta and Cheese: Add the cooked pasta to the skillet and gently mix to coat it in the sauce. Once well combined, stir in 2 cups shredded provolone cheese and 1/2 cup shredded mozzarella cheese until melted and creamy. Adjust seasoning with salt and black pepper as needed.
