Creating One-Pot Creamy Chicken Tomato Pasta is as easy as following these simple steps:

1. Heat the Oil: In a large pot or skillet over medium heat, add the olive oil.

2. Cook the Chicken: Season the chicken pieces with salt, pepper, and Italian seasoning. Add the chicken to the pot and cook until browned, approximately 5-7 minutes.

3. Add Garlic: Once the chicken is cooked through, stir in the minced garlic and cook for an additional 1 minute until fragrant.

4. Combine Tomatoes and Broth: Pour in the diced tomatoes (with their juices) and chicken broth. Stir well to combine.

5. Add Pasta: Bring the mixture to a rolling boil, then add the penne pasta. Stir occasionally to prevent sticking.

6. Simmer: Reduce the heat to medium-low and cover the pot. Allow the pasta to cook for about 12-15 minutes or until al dente, stirring occasionally.

7. Add Cream: Once the pasta is cooked, stir in the heavy cream and bring the mixture back to a gentle simmer.

8. Add Cheese: Remove the pot from the heat and mix in the grated Parmesan cheese until melted and creamy.

9. Taste and Adjust: Taste the dish and adjust the seasoning as necessary, adding more salt and pepper if desired.

10. Serve: Plate the pasta warm and garnish with freshly chopped basil leaves for a burst of flavor.
