Add the fresh basil leaves, grated parmesan cheese, garlic cloves, lemon zest and juice, and toasted pine nuts to a food processor or blender. Blend or pulse until the ingredients are all combined.
Next, as the food processor or blender is running, stream in the olive oil until all the ingredients are emulsified and you have a thick creamy consistency.
If the consistency is too thick add a little more lemon juice or olive oil. Season to taste and voila!
Notes
In this video we used a mini food processor and combined all the ingredients at once. Our results were great, but traditionally you would slowly stream in the olive oil to reach the consistency you desire. Have fun with it and do whichever you’d like.
