Creating One Pot Creamy Pesto Chicken Pasta can be straightforward if you follow these simple steps:

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

5. Incorporate Cream and Pesto: Remove the pot from heat and stir in the heavy cream and basil pesto until well combined.
6. Add Tomatoes: Gently fold in the cherry tomatoes, allowing them to warm through.
7. Adjust Seasoning: Taste and adjust the seasoning with additional salt and pepper if needed.
8. Serve: Garnish with fresh basil leaves and serve with grated Parmesan cheese if desired.
