Boil the Pasta: Bring a large pot of salted water to a boil. Add dried pasta noodles and cook until al dente, about 8-10 minutes. Reserve 3/4 cup of pasta cooking water before draining.

Prepare the Garlic Butter Sauce: In a non-stick skillet, melt butter over low heat. Add minced garlic and sauté for 1-2 minutes until fragrant.

Combine Pasta and Sauce: Add drained pasta to the skillet, tossing to coat. Incorporate grated Parmesan until melted and combined.

Adjust with Pasta Water: Slowly add reserved pasta water until desired sauce consistency is reached. Add remaining tablespoon of butter if needed.

Season and Serve: Season with salt and pepper, toss to combine, and serve immediately with extra Parmesan and parsley on top.
