Creating Garlic Butter Pasta is simpler than you think. Follow these step-by-step instructions:

1. Cook the Pasta: In a large pot, bring salted water to a boil. Cook the pasta according to the package instructions until al dente.
2. Drain the Pasta: Once cooked, reserve about a cup of pasta water, then drain the rest and set the pasta aside.
3. Melt the Butter: In a large skillet over medium heat, melt the unsalted butter until it foams and starts to turn golden.
4. Sauté the Garlic: Add minced garlic to the skillet and sauté for about 1-2 minutes, just until fragrant. Be careful not to let it burn.
5. Add Red Pepper Flakes: Stir in the red pepper flakes and cook for an additional 30 seconds.
6. Combine: Toss the cooked pasta into the skillet, mixing well with the garlic butter.
7. Add Parmesan Cheese: Slowly add the grated Parmesan cheese, stirring to combine thoroughly.
8. Adjust Consistency: If the pasta seems dry, slowly add reserved pasta water to achieve your desired consistency.
9. Season: Taste and season with salt, pepper, and more red pepper flakes if desired.
10. Finish with Parsley: Lastly, garnish with chopped fresh parsley for a burst of freshness.
