Bring 4 cups of salted water to a boil. Cook the pasta Al dente per package instructions.
Heat a saucepan over medium heat. Once hot, add olive oil and swirl to coat the bottom of the pan. This is done to prevent anything burning or sticking to the pan.
Reserve ½ cup pasta water. Drain the pasta and rinse under cold water. Set aside. The starch in the pasta water helps thicken the pasta sauce.
Stir and lower heat to a simmer. Cover. Cook for 10 minutes. Only remove the lid to stir every 3-4 minutes.
Add the pasta to the sauce and toss to coat. Keep over heat for 1-2 minutes to allow the pasta to absorb some of the liquid.
