Spaghetti Aglio et Olio

This is my new go to dinner when I need to throw something together last minute and don't have much in the fridge.  Since I nearly always have a box of spaghetti, some garlic and olive oil, I pretty much always have the ingredients on hand.  Since I happened to have a bunch of fresh parsley, I added that to the spaghetti, but even without the herbs, this is still delicious.

Ingredients:
4-5 cloves of fresh garlic peeled and sliced
1/3 cup good olive oil
pinch of red pepper flakes (if you want more spice add two pinches, less spice add less)
salt to taste
2/3 box of spaghetti
1/2 cup of pasta cooking water
fresh parsley (if desired)
fresh parmesan (if desired)

Directions:
Bring a pot of water to a boil and cook pasta according to box instructions for al dente.  While pasta is cooking heat olive oil in a large skillet over med-low heat.  Add garlic and pepper flakes. When garlic begins to turn light gold, remove from heat and set aside.  Once pasta is cooked to al dente, reserve one cup of the pasta water and add the pasta to the skillet with the olive oil. Toss well and add reserved pasta as needed to loosen the pasta. Add pinch of salt and top with fresh parsley and parmesan cheese.
