Creating the perfect Creamy Beef and Shells is straightforward if you follow these simple steps:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Add the pasta shells and cook according to package instructions until al dente. Drain and set aside.

2. Cook the Beef: In a large skillet, heat olive oil over medium heat. Add the diced onions and minced garlic, cooking until fragrant and soft, about 2-3 minutes.

3. Brown the Beef: Add the ground beef to the skillet. Break it apart with a spatula and cook until no longer pink, about 5-7 minutes. Drain excess fat, if necessary.

4. Prepare the Sauce: Lower the heat and stir in the beef broth and cream cheese. Keep stirring until the cream cheese is fully melted and creamy.

5. Season: Add Italian seasoning, salt, and black pepper to taste. Mix well to combine and let simmer for about 5 minutes.

6. Combine with Pasta: Gently fold in the cooked pasta shells until they are well coated with the creamy mixture.

7. Add Cheese: Sprinkle in the shredded cheddar cheese and stir until melted and evenly distributed.

8. Serve: Remove from heat and allow to cool for a few minutes. Garnish with fresh parsley, if desired.
