Cook the penne pasta according to package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the ground beef and cook until browned, breaking it apart with a spoon, about 5-7 minutes. Drain excess fat if necessary.
Add the minced garlic to the skillet and sauté for 1-2 minutes until fragrant.
Pour in the heavy cream and beef broth, stirring to combine. Bring the mixture to a simmer.
Stir in the grated Parmesan cheese and Italian seasoning. Continue to simmer for 3-5 minutes until the sauce thickens slightly.
Season with salt and pepper to taste.
Add the cooked penne pasta to the skillet, tossing to coat the pasta evenly with the sauce.
Serve hot, garnished with fresh parsley.
