Creating One Pot Creamy Garlic Pasta is straightforward when following these steps:

1. Heat Oil: In a large pot, heat the olive oil over medium heat.
2. Sauté Garlic: Add the minced garlic and sauté for 1-2 minutes until fragrant, but be careful not to burn it.
3. Add Broth and Pasta: Pour in the vegetable or chicken broth, followed by the uncooked fettuccine or spaghetti. Stir to combine.
4. Season the Mixture: Add garlic powder, Italian seasoning, salt, and pepper. Stir well to ensure that the pasta is evenly coated with the broth and spices.
5. Bring to a Boil: Increase the heat to high, bringing the mixture to a gentle boil.
6. Reduce Heat and Simmer: Once boiling, lower the heat to medium-low and cover the pot. Let the pasta simmer, stirring occasionally, until it becomes cooked through and most of the liquid is absorbed, which will take about 10-12 minutes.
7. Add Cream and Parmesan: Once the pasta is cooked, stir in the heavy cream and grated Parmesan cheese. Mix until the cheese has melted and the sauce becomes creamy and well combined.
8. Taste and Adjust: Check for seasoning, and adjust with more salt or pepper if needed.
9. Serve: Remove from heat. Garnish with fresh parsley if desired, and serve immediately.
