Add basil, pine nuts, garlic, Parmesan, lemon juice, salt, and black pepper to a food processor. Pulse until finely chopped.

With the processor running, slowly drizzle in the olive oil until the pesto is smooth and creamy. Scrape down the sides as needed.

Taste and adjust seasoning with more salt, pepper, or lemon juice if desired.

Use immediately or store in an airtight container in the refrigerator. To keep it bright green, pour a thin layer of olive oil over the top before storing.

Enjoy!
