1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the pasta shells and cook according to the package instructions until al dente. Drain the cooked pasta and set it aside.

2. Brown the Beef: 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 it’s browned and no longer pink. Drain any excess fat from the skillet.

3. Add Flavor: 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.

4. Create Creaminess: Gradually stir in the heavy cream, mixing well until everything is combined. Allow the creamy beef mixture to simmer on low heat for another 5 minutes, until it thickens slightly.

5. Combine Pasta and Sauce: Gently fold the cooked pasta shells into the creamy beef mixture, making sure each shell is coated in that luscious sauce. Taste and adjust the seasoning with salt and pepper as needed.

6. Serve and Enjoy: Transfer the Creamy Beef and Shells to plates or bowls, and garnish with a sprinkle of extra Italian seasoning, if desired. Serve hot and savor every bite of this comforting, flavor-packed dish!
