Pistachio pesto is a Sicilian version of classic basil pesto. The pistachios create a buttery flavor and subtle sweetness. Made with pistachios, basil, garlic, lemon, and olive oil, this recipe can be tossed with pasta, spread on sandwiches, or spooned on roasted vegetables. or served with bread.
Toast the Pistachios: Start by toasting the pistachios in a dry skillet for 3-4 minutes. This step will deepen their flavor.
Blend the Base: In a food processor, pulse pistachios and garlic until they are roughly chopped. Add basil, lemon zest, and lemon juice. Pulse again.
Stream in the Olive Oil: With the processor running, slowly add olive oil until the pesto smoothens, but still textured. If you want a creamier texture, continue to add olive oil in small increments until you achieve your desired consistency.
Fold in the Cheese: Add Parmesan and pulse just once or twice. Taste and adjust salt to your taste. Note: You want it slightly looser than you think — it will thicken in the fridge.
