Spaghetti Aglio e Olio

Step 1: Bring large pot of salted water to a boil. Cook spaghetti according to package directions, reserve about 1 cup pasta water, then drain.

Step 2: While pasta is cooking, in a large skillet over medium heat, combine oil, garlic and red pepper flakes, cook, stirring often, until just beginning to turn golden, 2-3 minutes. Be careful not to let garlic burn.

Step 3: Add drained spaghetti to skillet, and toss to evenly coat. Add reserved pasta water a little at a time, stirring until desired consistency is reached.

Step 4: Season with salt and pepper, to taste. Stir in parsley and lemon zest.

Step 5: Serve immediately, topped with cheese, if desired. Refrigerate any leftovers.
