Creating One Pot Creamy Pesto Sauce Pasta is straightforward and enjoyable. Follow these simple steps:

1. Boil Water: In a large pot, bring 4 cups of water to a boil. Add a pinch of salt for flavor.
2. Cook Pasta: Add the pasta to the boiling water and cook according to package instructions, usually around 8-10 minutes, until al dente. Stir occasionally to prevent sticking.
3. Drain and Reserve Water: Once the pasta is cooked, reserve about a cup of pasta water and then drain the rest.
4. Combine Ingredients: In the same pot, return the drained pasta and pour in the heavy cream. Stir until combined.
5. Add Pesto Sauce: Mix in the pesto sauce, and stir well until the pasta is fully coated.
6. Incorporate Cheese: Add the grated Parmesan cheese to the pot. Stir continuously until it melts into a creamy sauce.
7. Adjust Consistency: If the sauce is too thick, gradually add the reserved pasta water until you reach your desired creaminess.
8. Season: Season with salt and pepper to taste, mixing thoroughly.
9. Serve Immediately: Serve hot, garnished with extra Parmesan or fresh basil if desired.
