01 - Bring a large pot of salted water to a rolling boil.
02 - In a food processor, combine basil, pine nuts, garlic, and Parmesan. Pulse until finely chopped.
03 - With the motor running, slowly drizzle in the olive oil until the mixture is smooth and creamy. Season with salt, pepper, and lemon juice. Taste and adjust seasoning as needed.
