Creating Creamy Garlic Parmesan Spaghetti is straightforward. Just follow these step-by-step instructions:

1. Cook the Spaghetti: In a large pot, bring salted water to a boil. Add the spaghetti and cook according to package instructions until al dente. Reserve 1 cup of pasta water before draining.
2. Melt the Butter: In a large skillet, melt the butter over medium heat.
3. Sauté Garlic: Add the minced garlic to the melted butter and sauté for about 1-2 minutes, or until fragrant. Be careful not to burn the garlic.
4. Add Heavy Cream: Slowly pour in the heavy cream, stirring constantly to combine with the garlic and butter.
5. Incorporate Parmesan Cheese: Gradually whisk in the grated Parmesan cheese until the sauce is smooth and creamy.
6. Season: Season with salt and pepper to taste. For added flavor, you may add red pepper flakes if desired.
7. Combine Pasta and Sauce: Add the drained spaghetti to the sauce in the skillet. Toss until the pasta is well coated. If the sauce is too thick, add reserved pasta water a little at a time until desired consistency is reached.
8. Serve: Remove from heat and garnish with freshly chopped parsley before serving.
