A classic genovese pesto with a twist of pistachios instead of pine nuts. Pistachio pesto is a delicious and creamy pesto perfect for pastas and sandwiches.
Combine basil, garlic, salt, lemon juice, and pistachios in a food processor. Process until completely processed.
Turn the processor on low speed and slowly drizzle the olive oil into the pesto until it reaches the desired texture. ½ cup of olive oil will make a creamy and thicker pesto. Add more olive oil and lemon juice for a thinner pesto.
Mix in the parmigiana. Serve with pasta or on sandwiches!
Notes
Buy already peeled pistachios. It's much easier than trying to peel all of the shell off of a pistachio.
If you are looking to thin out the pesto, make sure to add olive oil as well as a little more lemon juice to even out the flavor. Keep in mind, if you're making with pasta, you can always add a little pasta water to thin out the pesto.
