Ingredients:
3 cups packed fresh basil leaves
¾ cup grated Parmesan cheese
½ cup olive oil
¼ cup pine nuts or walnuts
4 cloves garlic, or to taste
2 teaspoons lemon juice, or more to taste (optional)
Directions:
Combine basil, Parmesan cheese, olive oil, pine nuts, and garlic in the bowl of a food processor or blender. Blend to a smooth paste. Add lemon juice, if desired, and quickly pulse to combine.
To store, add a bit more olive oil on top of the pesto while its in your container. It freezes pretty well.
