Step 1

Combine basil leaves, pine nuts, Parmesan cheese, garlic, and lemon juice in a bowl of a food processor. Pulse until finely minced. Scrape down the sides with a spoon or small rubber spatula.

Step 2

While the food processor is running, slowly add the olive oil in a steady small stream. Scrape down the sides as needed. Season with salt and pepper to taste. Use immediately or refrigerate for up to 1 week. See notes for freezer instructions.
