Creating One Pot Creamy Tomato Pasta is simple if you follow these steps:

1. Sauté Onions and Garlic: In a large pot, heat a drizzle of olive oil over medium heat. Add the chopped onion and sauté until translucent, about 3-4 minutes. Add the minced garlic and cook for an additional 1-2 minutes until fragrant.

2. Add Tomatoes and Broth: Stir in the diced tomatoes (with juice), vegetable or chicken broth, and the dried herbs. Bring the mixture to a simmer.

3. Incorporate Pasta: Add the pasta to the pot, ensuring it is submerged in the liquid. Stir occasionally to prevent sticking.

4. Cook Pasta: Cover the pot and cook the pasta according to the package instructions, usually around 10-12 minutes, until al dente. Stir occasionally to ensure even cooking.

5. Stir in Cream: Once the pasta is cooked, reduce the heat to low. Stir in the heavy cream and grated Parmesan cheese until the sauce is creamy and smooth.

6. Season to Taste: Add salt, pepper, and red pepper flakes (if using) to taste. Stir well to combine all flavors.

7. Garnish and Serve: Remove from heat and garnish with fresh basil leaves and additional Parmesan cheese if desired.

8. Enjoy: Serve immediately and enjoy the rich, creamy goodness of your One Pot Creamy Tomato Pasta.
