Preheat oven to 375 degrees.
Spread pine nuts on a cookie sheet and bake for 8 1/2 minutes or until golden brown.
In a blender or food processor, pulse the basil, pine nuts, garlic, 1/2 teaspoon salt, and 1/4 teaspoon pepper until finely chopped.
With the machine running, gradually add the oil until the mixture is smooth and thick.
Add the cheese and pulse until just incorporated.
Season with additional salt and pepper, to taste if desired.
