Ingredients

  • 2 cups fresh basil leaves (packed, washed and dried)
  • 2 cloves garlic (minced)
  • 2 tablespoons pine nuts (lightly toasted)
  • 2 tablespoons nutritional yeast (for cheesy flavor)
  • 1 tablespoon lemon juice (freshly squeezed)
  • 3 tablespoons water (or adjust for desired consistency)
  • 1 tablespoon extra virgin olive oil (optional, for smoothness)
  • Salt and pepper (to taste)

Equipment

  • Food processor or blender
  • Measuring spoons
  • Spatula
  • Small bowl (for toasting pine nuts)
  • Citrus juicer (optional, for lemon juice)

Instructions

  1. Toast the pine nuts: Heat a dry skillet over medium heat. Add the pine nuts and toast for 2-3 minutes until golden and fragrant, stirring frequently to prevent burning. Remove from heat and let cool.
  2. Prepare basil and garlic: Wash and dry fresh basil leaves thoroughly to avoid water diluting the sauce. Peel and mince the garlic cloves finely.
  3. Combine ingredients: In your food processor or blender, add the basil leaves, toasted pine nuts, minced garlic, and nutritional yeast.
  4. Add liquids: Pour in the lemon juice and 2 tablespoons of water. Add the olive oil if using, to enhance smoothness and richness.
  5. Blend the mixture: Pulse the ingredients until they start to come together. Scrape down the sides with a spatula as needed to ensure even blending.
  6. Adjust consistency: Add the remaining tablespoon of water slowly while blending until you reach your desired sauce consistency. It should be creamy but not too runny.
  7. Season to taste: Add salt and freshly cracked black pepper according to your preference. Give it one last blend to mix.
  8. Store or serve: Transfer the pesto to a clean jar or container. Use immediately or refrigerate for up to 5 days. If refrigerated, bring to room temperature and stir before serving.

Tips & Variations

“For an even lighter twist, swap pine nuts with shelled pumpkin seeds or walnuts. These nuts add texture and nutrition while keeping calories low.”

  • Use fresh herbs: While basil is traditional, try mixing in some fresh parsley or arugula for a different flavor profile.
  • Make it nut-free: Replace pine nuts with sunflower seeds to accommodate nut allergies.
  • Boost flavor: Add a small pinch of red pepper flakes for a mild kick or a teaspoon of capers for briny tang.
  • Cheese-free option: Nutritional yeast is a great vegan alternative to Parmesan, but if you want to add cheese without too many calories, use a small amount of grated Pecorino Romano.
  • Storage tip: To keep your pesto bright green, drizzle a thin layer of olive oil on the surface before storing.
