In a food processor or blender, combine basil and about 2 tablespoons of the extra virgin olive oil, blend into a paste. Add pine nuts, Parmesan cheese, garlic, and remaining oil and pulse until smooth. Season with salt and pepper to taste.
Notes
Makes about 1 ½ cups.
Basil Pesto can be made up to three days in advance. Refrigerate it in a sealed container.
If you cannot find pine nuts, you can substitute them with a variety of other items such as walnuts, almonds, sunflower seeds, or pistachios.
If you prefer your basil pesto to be a little thinner, simply drizzle in more olive oil until you reach the desired consistency.
