In a small pan over medium heat, toast the nuts until fragrant, about 3 minutes. Allow to cool.

In a food processor or blender, add the basil, garlic, salt and pepper, parmesan, and nuts. Blend until well combined, pushing down with a spatula if needed.

With the processor running, slowly add the olive oil until everything is combined and reaches a more creamy consistency.

Serve with pasta, grilled chicken, veggies, or anything else you'd like. Store in an airtight container in the fridge.
