Ingredients
Method
- Bring a large pot of heavily salted water to a boil. Cook the pasta until al dente, about 10 to 12 minutes. Reserve 1 cup of pasta water, then drain.
- In a food processor, pulse the pistachios and garlic until finely chopped. Add the basil, lemon juice, salt, and Parmesan. With the machine running, slowly pour in the olive oil and blend until a thick paste forms.
- Toss the drained pasta with the pesto, adding splashes of reserved pasta water as needed to loosen the sauce. Serve with extra Parmesan, crushed pistachios, and a drizzle of olive oil.
Notes
Be careful not to rinse the pasta after draining; the starch helps the pesto stick. For a creamier pesto, add a few tablespoons of the reserved pasta water directly to the food processor and blend briefly before tossing.
