It's a versatile and delicious pesto alternative that brings a nutty twist to classic basil pesto.

  • Total Time: 10 minutes
  • Yield: 1 serving (approximately ½ cup pesto)

Ingredients

For the Pesto

  • 4 ounces fresh basil (about 2 cups packed leaves)
  • ¼ cup walnut halves or pieces
  • 1 garlic clove, peeled and smashed
  • 1 teaspoon lemon juice
  • ¼ cup + 2 tablespoons extra-virgin olive oil or avocado oil
  • Sea salt to taste
  • Fresh ground black pepper to taste

Instructions

  1. Prepare Ingredients: Gather fresh basil leaves, walnuts, garlic, lemon juice, and oil. Measure out the quantities carefully to balance flavors.
  2. Pulse Basil, Walnuts, Garlic, and Lemon Juice: Add the basil, walnuts, garlic clove, lemon juice, and ¼ cup of the oil into the bowl of a food processor or high-speed blender. Pulse the ingredients until they are finely chopped and begin to form a smooth but slightly textured mixture.
  3. Incorporate Remaining Oil: With the food processor motor running, slowly add the remaining 2 tablespoons of oil through the chute in the lid to emulsify and smooth the pesto to your desired consistency.
  4. Season to Taste: Stop the processor and taste the pesto. Add sea salt and freshly ground black pepper as needed, then pulse briefly to combine the seasoning evenly.
  5. Serve or Store: Use immediately as a sauce or spread, or transfer to an airtight container and refrigerate for up to 3 days to maintain freshness.

Notes

  • Use fresh, young basil leaves for the best flavor and bright color.
  • Walnuts add a rich, earthy taste; you can toast them lightly for extra depth.
  • Adjust the amount of garlic and lemon juice to suit your taste preferences.
  • This pesto can be frozen in ice cube trays for easy portioning and longer storage.
  • Substitute avocado oil if you prefer a milder flavor or have olive oil sensitivity.
