2ouncesspaghettior use your favorite pasta. (Two ounces of dried spaghetti is about the width of a quarter when bunched. For shapes like penne or ziti, use ⅔ cup to equal 2 ounces.)
Bring a medium pot of water to a rolling boil. Cook the pasta according to the package instructions. Before draining, reserve 1/4 cup of the pasta water. Drain the pasta and transfer it to a bowl.
Add the pesto and 1 to 2 tablespoons of the reserved pasta water. Toss to coat the pasta evenly. Add more water if needed for a smoother sauce.
Stir in 2 tablespoons of shredded Parmesan. Taste and add a pinch of salt if needed.
Top with an extra tablespoon of Parmesan and serve.
Notes
Don’t mix the pesto on the stove. Transfer the hot pasta to a bowl, then add the pesto. The pasta’s heat is enough to warm the sauce.
A squeeze of lemon before serving adds a bright, fresh flavor.
Pesto pasta can be made ahead and stored in the fridge for up to 3 days.
Homemade pesto is usually brighter green than store-bought.
