Cook the pasta according to package instructions until al dente. Drain and set aside.
In a large skillet, heat olive oil over medium-high heat. Add the sliced ribeye and season with salt and pepper. Sear until browned, about 2-3 minutes.
Add the sliced onions and bell pepper to the skillet. Sauté for 4-5 minutes until softened.
Stir in the minced garlic and cook for another minute until fragrant.
Pour in the beef broth, stirring to deglaze the pan, scraping up any browned bits. Let simmer for 3-4 minutes.
Reduce the heat to low and add the heavy cream, stirring until combined.
Gradually add the shredded provolone cheese, stirring until melted and smooth.
Toss the cooked pasta in the sauce, mixing thoroughly to coat.
Taste and adjust seasoning with additional salt and pepper, if needed.
Serve immediately, garnishing with additional cheese or chopped parsley if desired.
