📝 About This Recipe

Transport your palate to the sun-drenched groves of Bronte, Sicily, with this luxurious twist on the classic Genovese sauce. Unlike traditional pine nut versions, this pesto offers a sophisticated, buttery depth and a vibrant green hue that feels truly celebratory. It is a harmonious balance of roasted nutty notes, the sharp bite of aged Pecorino, and the aromatic lift of fresh citrus zest.

🥗 Ingredients

The Nut Base

  • 1 1/2 cups Shelled Pistachios (unsalted, raw or lightly roasted with skins removed)

Fresh Herbs and Aromatics

  • 2 cups Fresh Basil Leaves (packed, washed and thoroughly dried)
  • 1/4 cup Fresh Mint Leaves (adds a bright, Sicilian flair)
  • 2 pieces Garlic Cloves (medium sized, germ removed for a milder flavor)
  • 1 teaspoon Lemon Zest (finely grated from an organic lemon)

Cheeses and Oils

  • 1/2 cup Pecorino Romano (freshly grated)
  • 1/4 cup Parmigiano Reggiano (freshly grated)
  • 3/4 cup Extra Virgin Olive Oil (high quality, cold-pressed)

Seasoning

  • 1/2 teaspoon Sea Salt (adjust to taste)
  • 1/4 teaspoon Freshly Cracked Black Pepper (optional)
  • 1-2 tablespoons Ice Water (to maintain vibrant green color)

👨‍🍳 Instructions

  1. 1

    If your pistachios are raw, lightly toast them in a dry skillet over medium heat for 3-5 minutes until fragrant. Be careful not to brown them too deeply, as this will dull the green color.

  2. 2

    Place the toasted pistachios in a clean kitchen towel and rub them together vigorously to remove any loose papery skins. Discard the skins and let the nuts cool completely.

  3. 3

    In a food processor or high-speed blender, add the cooled pistachios and the garlic cloves.

  4. 4

    Pulse the nuts and garlic about 5-8 times until they reach a coarse, sand-like consistency. Do not over-process into a paste yet.

  5. 5

    Add the fresh basil and mint leaves to the processor. Tip: Ensure the herbs are bone-dry to prevent the pesto from becoming watery.

  6. 6

    Add the lemon zest, sea salt, and black pepper to the herb mixture.

  7. 7

    Pulse again several times until the herbs are finely chopped and incorporated with the nuts.

  8. 8

    With the processor running on low speed, slowly drizzle in the extra virgin olive oil in a thin, steady stream. This creates a beautiful emulsion.

  9. 9

    Stop the processor and scrape down the sides with a rubber spatula to ensure everything is evenly mixed.

  10. 10

    Add the grated Pecorino Romano and Parmigiano Reggiano. Pulse only 2-3 times just to combine; over-mixing the cheese can make the texture gummy.

  11. 11

    If the pesto feels too thick, add 1 tablespoon of ice-cold water and pulse once. The cold water helps emulsify the oil and keeps the basil from oxidizing.

  12. 12

    Taste the pesto. Depending on the saltiness of your cheese, you may want to add a pinch more salt or a squeeze of lemon juice for acidity.

  13. 13

    Transfer the pesto to a glass jar. If not using immediately, pour a thin layer of olive oil over the top to seal out air and prevent browning.

💡 Chef's Tips

Use the brightest green pistachios you can find (often labeled 'Bronte' or 'Grown in Sicily') for the most stunning visual result. Avoid using a high-speed blender on the highest setting, as the heat from the blades can 'cook' the basil and turn it brown. If you prefer a rustic texture, use a large mortar and pestle to grind the ingredients by hand starting with the garlic and nuts. Always grate your cheese fresh; pre-grated cheeses are coated in cellulose which prevents the pesto from reaching a creamy consistency. To store, keep in the refrigerator for up to 5 days or freeze in ice cube trays for easy portioning later.

🍽️ Serving Suggestions

Toss with al dente Trofie or Linguine pasta and a splash of starchy pasta water for a silky coating. Dollop over grilled swordfish or roasted salmon to add a rich, nutty crust. Spread onto toasted sourdough crostini topped with a slice of fresh burrata and a drizzle of honey. Use as a vibrant base sauce for a white pizza topped with mozzarella and mortadella. Thin it out with a little more oil and lemon juice to create a decadent dressing for a heirloom tomato salad.
