1. Cook the Spaghetti:
   • Bring a large pot of salted water to a boil.
   • Add the spaghetti and cook according to package instructions until al dente.
   • Reserve 1/2 cup of the pasta cooking water, then drain the spaghetti.
2. Prepare the Sauce:
   • While the spaghetti is cooking, heat the olive oil in a large skillet over medium heat.
   • Add the sliced garlic and red pepper flakes. Cook, stirring frequently, until the garlic is golden brown (about 2-3 minutes). Be careful not to burn the garlic.
3. Combine Pasta and Sauce:
   • Add the cooked spaghetti to the skillet with the garlic and oil.
   • Toss to combine, adding a little of the reserved pasta water to create a silky sauce.
   • Season with salt and freshly ground black pepper to taste.
4. Serve:
   • Divide the pasta among plates.
   • Sprinkle with chopped parsley and grated Parmesan cheese, if using.
   • Serve immediately.

Enjoy your quick and tasty meal!
