1/4 cup extra-virgin olive oil, plus more for brushing
1/4 cup pine nuts
2 garlic cloves, smashed
1/4 cup freshly grated Parmesan cheese
2 cups (lightly packed) basil leaves
1/2 teaspoon fresh lemon juice
How to Make It
Brush a small skillet with olive oil and heat. Add the pine nuts and toast over moderately high heat, stirring constantly, until golden, about 3 minutes. Transfer to a plate to cool.
In a food processor or blender, pulse the pine nuts with the garlic and Parmesan until finely chopped. Add the basil and pulse until minced, scraping down the side of the bowl. With the machine on, add the 1/4 cup of olive oil in a thin stream and process until smooth. Add the lemon juice and season with salt.
The pesto can be refrigerated overnight; press a piece of plastic wrap directly on the surface to keep the pesto from discoloring.
