In a large pot, bring salted water to a boil. Add the pasta and cook according to package directions until al dente. Reserve 1 cup of the pasta water and then drain the rest.
In a large skillet, melt the butter over medium heat. Add the minced garlic and sauté for 2-3 minutes until it becomes fragrant and golden.
Add the cooked pasta directly into the skillet with the garlic butter. Toss to coat the pasta evenly.
Stir in the red pepper flakes, reserved pasta water (a little at a time until desired consistency), lemon zest, and half of the parsley. Season with salt and pepper to taste.
Remove from heat and sprinkle in the grated Parmesan cheese. Toss until everything is well combined and the cheese has melted into the pasta.
Portion the pasta into serving bowls and garnish with remaining parsley and fresh basil leaves. Finish with additional Parmesan cheese on top if desired.
Notes
Feel free to adjust the amount of red pepper flakes for desired heat.
