Ingredients
Method
- Set a large pot of salted water to boil. Combine basil, pine nuts, garlic, Parmesan, salt, and pepper in a blender. Pulse, then drizzle in olive oil with the motor running and blend until almost smooth, about 30 seconds.
- Scrape the sides, add heavy cream and lemon juice, and pulse until silky, about 10 seconds. Do not over-blend.
- Cook pasta al dente, reserve 1 cup starchy water, then drain. Return pasta to low heat, add pesto, and toss 1 to 2 minutes with splashes of reserved water until glossy. Serve hot with extra Parmesan.
Notes
For the smoothest sauce, make sure the cream is at room temperature before blending. If you are serving later, toss the pasta with just a little oil first and store the sauce separately, combining them when reheating.
