1. Begin by bringing a large pot of salted water to a boil. Add the pasta shells and cook according to the package instructions until they’re al dente. Drain the pasta and set it aside.

2. In a large skillet over medium heat, add the ground beef, chopped onion, and minced garlic. Cook, breaking up the beef with a spatula, until the meat is browned and no longer pink. Drain any excess fat from the skillet.

3. Pour the beef broth into the skillet and stir in the Italian seasoning. Let the mixture simmer for about 5 minutes, allowing the flavors to meld together.

4. Stir in the heavy cream, ensuring that all the ingredients are well combined. Allow the sauce to simmer on low heat for an additional 5 minutes, or until it thickens slightly.

5. Gently fold the cooked pasta shells into the creamy beef mixture, making sure each shell is coated in the luscious sauce. Adjust the seasoning with salt and pepper as needed.

6. Transfer the Creamy Beef and Shells to plates or bowls, and garnish with a sprinkle of extra Italian seasoning if desired. Serve the dish hot and savor every bite.
