Preheat the oven to 350°F. Toast the walnuts on a rimmed baking sheet in the oven for approximately 8 minutes. After they turn slightly golden, take them out of the oven to cool.
Chop the garlic in the food processor for several pulses.
Place the basil, nutritional yeast, lemon juice, sea salt, and walnuts in the bowl of the food processor. Pulse several times until mixed. Scrape down the sides as needed.
Add olive oil in a steady stream and continue pulsing until it is combined. Serve immediately. See notes for storage instructions.
Notes
1 serving is approximately 2 tablespoons.
Add water, a tablespoon at a time, for a thinner consistency.
I love nutritional yeast and add a generous amount; feel free to reduce the amount by half or omit it. It will still be delicious.
Store in an airtight glass container and refrigerate for up to 5 days.
To freeze, spoon it in an ice cube tray. Once frozen, place the cubes in a Ziploc bag and store them in the freezer for up to 4 months.
