Preparation: Make sure the pistachios are shelled and the basil is clean and dry.
Mixing: Place the basil, pistachios, Parmesan cheese, garlic, lemon zest, and juice in a food processor. Add the olive oil.
Blending: Blend until you have a coarse pesto. Add a small splash of water if the mixture is too thick to blend.
Seasoning: Season with pepper and salt and mix briefly again.
Tips
Use unsalted pistachio nuts for better control over the taste.
Store the pesto in a well -sealed jar in the fridge (maximum 1 week) or freeze it in small portions for longer shelf life.
Also try this pesto as a topping on grilled vegetables or as a seasoning in a sandwich.
