Instructions

Step 1: In a large deep skillet or wide saucepan, combine 12 oz spaghetti, 5 cups water, 1 tsp salt, 1/4 cup extra virgin olive oil, 6 thinly sliced garlic cloves, and 1 tsp red chili flakes. Bring to a boil over high heat.
Step 2: Reduce heat to medium and simmer, stirring frequently, for 9-11 minutes until the spaghetti is al dente and most of the water has evaporated, leaving a silky sauce that coats the pasta.
Step 3: Remove from heat and stir in 1/4 cup chopped fresh flat-leaf parsley and 1/2 cup grated Parmesan cheese. Season with black pepper to taste and toss well before serving immediately.
