Prep: In a large, oven-safe skillet, cook ground beef until no longer pink, breaking it up as it cooks.
Meanwhile, cook the pasta according to package directions. Drain and set aside.
Dice the bell peppers, chop the onion, and mince the garlic while the beef and pasta cook.
Assemble: Add bell peppers, onions, and garlic to the ground beef and sauté until softened, about 10 minutes.
Pour in the beef broth, heavy cream, Worcestershire sauce, and all the seasonings.
Bring to a gentle simmer then reduce heat to low and add provolone cheese. Stir continuously until the cheese is fully melted.
Spoon pasta into the sauce, stirring as you go.
Broil: Turn your oven broil setting to high.
Top the pasta with the mozzarella cheese and broil the whole dish for 2-3 minutes, until the cheese is fully melted. Sprinkle fresh parsley on top and serve. Enjoy!
