Method
- Add the cashews, garlic, and Parmesan to the bowl of a small food processor. Pulse several times until the mixture resembles coarse crumbs.
- Add the fresh basil and pulse again until the leaves are broken down and incorporated.
- Pour in the olive oil and add salt. Blend until smooth and creamy, scraping down the sides as needed.
- Adjust consistency with more olive oil if you'd like it looser.
- Serve immediately or transfer to an airtight jar.
Notes
- Nut variations: Almonds, walnuts, pecans, and hazelnuts all work as substitutes at a 1:1 ratio by weight. See the comparison section in the post for flavor differences.
- No nuts: Omit entirely and increase Parmesan slightly for a lighter pesto.
- Toasting: Toast cashews in a dry pan for 3-4 minutes before blending for deeper flavor.
- Storage: Refrigerate in an airtight jar up to 5 days. Drizzle olive oil over the surface to prevent browning.
- Freezing: Freeze in an ice cube tray, transfer cubes to a freezer bag. Keeps up to 3 months.
