Ingredients:

  • packed cups (60g) fresh basil leaves, stems removed
  • /2 cup (60g) raw walnuts
  • /4 cup (25g) freshly grated Parmesan cheese
  • medium garlic cloves
  • /4 cup (60g) plain Greek yogurt (2% or 5% fat)
  • tablespoons (30ml) extra virgin olive oil
  • tablespoon (15ml) fresh lemon juice
  • /2 teaspoon lemon zest
  • /2 teaspoon kosher salt (or to taste)
  • /4 teaspoon freshly ground black pepper (or to taste)
  • tablespoons ice water (optional, for thinning)

Instructions:

  1. Heat a small, dry skillet over medium heat. Add walnuts and toast, stirring frequently, until fragrant (about 3-5 minutes). Immediately transfer to a plate to cool completely.
  2. Add the cooled toasted walnuts and garlic cloves to the food processor bowl. Pulse several times until coarsely chopped.
  3. Add the packed basil leaves and Parmesan cheese to the processor. Pulse until the basil is finely chopped and incorporated with the nuts. Scrape down the sides.
  4. Add the Greek yogurt, olive oil, lemon juice, and lemon zest. Pulse until the mixture begins to come together into a thick paste.
  5. Add salt and pepper. Pulse briefly once more.
  6. If the pesto is too thick, slowly drizzle in 1 tablespoon of ice water while pulsing, until the desired, slightly looser consistency is reached. Do not add too much liquid.
  7. Taste and adjust seasoning if necessary (more salt, more lemon). Use immediately or store airtight in the fridge.
