Ingredients

  • 1 cup walnuts (preferably raw)
  • 2 cups fresh basil leaves, packed
  • 3 cloves garlic, peeled
  • 1/4 cup nutritional yeast (adds cheesy flavor)
  • 1/2 cup extra-virgin olive oil
  • 2 tablespoons fresh lemon juice
  • 1/4 teaspoon salt (adjust to taste)
  • Freshly ground black pepper, to taste
  • Optional: 1-2 tablespoons water (to thin the pesto if needed)

Equipment

  • Food processor or high-speed blender – for blending the pesto ingredients smoothly
  • Measuring cups and spoons – to get the ingredient amounts just right
  • Spatula – to scrape down the sides and mix
  • Jar or airtight container – for storing leftover pesto

Instructions

  1. Toast the walnuts: Place the walnuts in a dry skillet over medium heat. Toast for 5-7 minutes, stirring frequently, until fragrant and lightly browned. This step enhances their nutty flavor. Allow to cool slightly.
  2. Prepare the basil: Rinse the fresh basil leaves and pat dry with a paper towel to remove excess moisture.
  3. Add ingredients to the food processor: Combine the toasted walnuts, basil leaves, garlic cloves, nutritional yeast, lemon juice, salt, and pepper in the bowl of your food processor.
  4. Pulse to combine: Pulse the mixture several times to roughly chop and mix the ingredients.
  5. Stream in olive oil: While the processor is running, slowly drizzle in the olive oil. Continue processing until the pesto reaches your desired consistency. If it’s too thick, add 1 tablespoon of water at a time to thin it out.
  6. Taste and adjust: Sample the pesto and adjust salt, pepper, or lemon juice as needed for balance.
  7. Store or serve: Transfer your walnut pesto to a jar or airtight container. It can be used immediately or refrigerated for up to 5 days. For longer storage, freeze in small portions.

Tips & Variations

“Freshness is key when making pesto—always use fresh basil and freshly toasted walnuts for the best flavor!”

  • Nut alternatives: While walnuts are the star here, you can experiment with pecans or almonds for a different but equally delicious twist.
  • Herb swaps: Try mixing basil with fresh parsley or spinach for a milder flavor and extra nutrients.
  • Garlic intensity: Adjust the garlic amount to your preference; roasting the garlic beforehand can mellow its bite.
  • Cheesy flavor: Nutritional yeast is essential for that cheesy undertone, but vegan parmesan can be used if preferred.
  • Make it spicy: Add a pinch of red pepper flakes for a subtle kick.
  • Storage tip: Pour a thin layer of olive oil on top of the pesto in the jar to prevent oxidation and keep it fresh longer.
