Pasta aglio y olio (with garlic and oil)

I adapted this from Ina Garten's recipe which calls for WAY more garlic. I've made it that way and, even for me, it's WAY too much garlic. 

Ingredients
Kosher salt
1 pound dried spaghetti
1/3 cup good olive oil
5 large garlic cloves, minced
1/2 teaspoon crushed red pepper flakes (not heaping)
1/2 cup minced fresh parsley
1 cup freshly grated Parmesan cheese, plus extra for serving

Directions
Bring a large pot of water to a boil. Add 2 tablespoons of salt and the pasta and cook according to the directions on the package. Set aside 1 1/2 cups of the pasta cooking water before you drain the pasta.

Meanwhile, heat the olive oil over medium heat in a pot large enough to hold the pasta, such as a 12-inch saute pan or a large, shallow pot. Add the garlic and cook for 2 minutes, stirring frequently, until it just begins to turn golden on the edges-don't overcook it! Add the red pepper flakes and cook for 30 seconds more. Carefully add the reserved pasta-cooking water to the garlic and oil and bring to a boil. Lower the heat, add 1 teaspoon of salt, and simmer for about 5 minutes, until the liquid is reduced by about a third.

If using angel hair, run a bit of cold water over it to make it less sticky, or add just a bit of olive oil for the same purpose. Add the drained pasta to the garlic sauce and toss. Off the heat, add the parsley and Parmesan and toss well. Allow the pasta to rest off the heat for 5 minutes for the sauce to be absorbed. Taste for seasoning and serve warm with extra Parmesan on the side.
