Ingredients

  • 2 cups fresh basil leaves, packed
  • 3 cloves garlic, peeled
  • 1/3 cup pine nuts (or walnuts for a budget-friendly alternative)
  • 1/2 cup extra virgin olive oil
  • 1/2 cup grated Parmesan cheese (optional for vegan version)
  • 1-2 fresh red chili peppers, seeded and chopped (adjust to taste)
  • 1/2 teaspoon crushed red pepper flakes
  • Juice of half a lemon
  • Salt and freshly ground black pepper, to taste

Equipment

  • Food processor or high-speed blender
  • Measuring cups and spoons
  • Spatula
  • Knife and cutting board
  • Glass jar or airtight container for storage

Instructions

  1. Prepare the ingredients. Wash the fresh basil leaves thoroughly and pat dry. Peel the garlic cloves and chop the fresh red chili peppers, removing seeds if you prefer less heat.
  2. Toast the pine nuts. In a dry skillet over medium heat, toast the pine nuts for 2-3 minutes, stirring frequently, until golden and fragrant. This step enhances their nutty flavor.
  3. Add basil, garlic, pine nuts, and chilies to the food processor. Pulse a few times to break down the ingredients.
  4. Slowly pour in the olive oil. With the processor running, drizzle the olive oil gradually until the mixture becomes a smooth paste.
  5. Incorporate the Parmesan cheese (if using), lemon juice, and crushed red pepper flakes. Pulse again until everything is well combined.
  6. Season with salt and freshly ground black pepper. Taste and adjust seasoning or spice level as needed. You can add more chili flakes or fresh chili for extra heat.
  7. Transfer the pesto to a jar. Cover with a thin layer of olive oil to prevent oxidation and store in the refrigerator. It will keep well for up to one week.

Tips & Variations

“For a vegan version, simply omit the Parmesan cheese or substitute with nutritional yeast for that cheesy flavor without dairy.”

If you’re looking to experiment, consider these ideas:

  • Nut alternatives: Swap pine nuts with almonds, cashews, or walnuts depending on your preference or budget.
  • Heat levels: Adjust the number of fresh chilies or red pepper flakes to suit your spice tolerance.
  • Herb blends: Mix in fresh parsley or cilantro for a different herbal profile.
  • Lemon zest: Add a teaspoon of lemon zest for an extra citrusy brightness.
  • Roasted garlic: Use roasted garlic instead of raw for a milder, sweeter garlic flavor.
