Bring a large pot of water (salted) to the boil and add the linguine (or pasta shape of your choice) Cook the pasta per package instructions for al dente. While the pasta cooks, start making the olive oil pasta sauce. When you drain the linguine, make sure to reserve ½ cup of pasta water
Add the olive oil to a large skillet over medium to medium-low heat.
When the oil is hot add the chopped garlic and red pepper flakes and saute for 1-2 minutes until the garlic is fragrant. *Don't let the garlic turn brown or burn, it should be a pale golden color. Add two tablespoons of the chopped parsley to the pan and continue to cook for 30-60 seconds.Set the pan aside until the linguine is cooked. Add the cooked pasta to the frying pan, and mix using tongs, coating the pasta with the garlic oil mixture.
Add the pasta water to the linguine, using as much as you feel necessary to get the desired consistency. The starchy pasta water will add flavor and combine with the oil to make a silky smooth garlic sauce
Add the remaining parsley, black pepper, and salt to the linguine, seasoning to taste.
Toss the pasta and heat for one minute over medium high heat or until the pasta and sauce is hot
Serve the pasta with grated cheese, crushed red pepper, and additional olive oil for drizzling over the pasta.
Store any leftover pasta in an airtight container in the fridge and reheat in a frying pan over medium heat, adding additional olive oil or water to the pan.
