Pistachio Pesto

This homemade pistachio pesto is creamy, nutty, and full of fresh flavor from basil, garlic, olive oil, Parmigiano, and Pecorino. It’s quick to make and delicious tossed with pasta, spread on crostini, or used to add flavor to simple Italian meals.

 

This pistachio pesto is the kind of recipe that feels fancy but takes less than 20 minutes in your food processor. It is a Sicilian-inspired twist on classic basil pesto, swapping pine nuts for shelled pistachios, which give the sauce a creamier texture and a deeper, nuttier flavor.

It is one of those recipes that proves pesto is more of a method than a single recipe. Once you have made this one, it is worth playing around with arugula pesto, asparagus pesto, and zucchini pesto too, since each one brings its own seasonal personality to the table.

Ingredient Notes

• Shelled pistachios: Use unsalted shelled pistachios so you can control the seasoning yourself. A quick boil makes the skins easy to rub off, which gives the pesto a smoother texture and that bright green color.
• Fresh basil: Just a few leaves do the trick here. The basil adds a hint of freshness without taking over, so the pistachios stay the star.
• Garlic: One clove is plenty. It adds a savory backbone without competing with the pistachios.
• Olive oil: Add the extra virgin olive oil in stages as you blend. If the pesto feels too thick, stream in a little more oil or a splash of water until it reaches the consistency you want.
• Parmigiano and Pecorino: Using both cheeses gives the pesto a nice balance of nutty, salty, and sharp. Grate them fresh, since pre-grated cheese does not blend in as smoothly.
• Salt and black pepper: Start with a pinch of salt, then taste and adjust at the end. A dash or two of black pepper is optional if you want a little extra warmth.

How to Make Pistachio Pesto

Bring a pot of water to a boil and drop in the shelled pistachios for a few minutes. Drain them, then rub them with a clean kitchen towel to slip off the papery skins.

This is what gives pistachio pesto that vibrant green color instead of a muddy brownish one, so it is worth the extra few minutes.

Add the peeled pistachios, basil, garlic, salt, and half the olive oil to your food processor. Pulse in short bursts rather than running it continuously. This keeps the motor from overheating and stops the pesto from turning into a paste before you are ready.

Stream in the remaining olive oil, then add the Parmigiano and Pecorino. Keep pulsing until the pesto is creamy with just a little texture. You want it slightly grainy, not perfectly smooth. That little bit of bite is what makes it taste homemade.

If it feels too thick, add another tablespoon of olive oil or a splash of water and pulse again. Taste it, then add more salt if it needs it.

Ways to use Pistachio Pesto

This pistachio pesto is the kind of sauce that does not need much to shine. Toss it with hot pasta and a splash of the cooking water, and you have dinner in the time it takes to boil the noodles.

Long shapes like homemade pasta or short ridgy pasta such as rigatoni let the sauce cling to every strand, or try it stirred into shrimp pasta for something a little more special.

It is also delicious spread on pesto pizza instead of tomato sauce or spooned over grilled chicken and fish. Stir a spoonful into ricotta for a quick dip, or swirl it into minestrone or tomato soup for a nutty, herby finish.

This Pistachio Pesto is a delicious twist on classic pesto, combining the rich, nutty flavor of pistachios with fresh herbs and Parmesan for a smooth and versatile sauce. Whether tossed with pasta, spread on crostini, or spooned over grilled meats and vegetables, it’s an easy way to bring a touch of Italian flavor to any meal. Buon Appetito!
