Arugula pesto is a quick, 5-minute sauce that’s nutty, peppery, bright, and spoon-worthy. This easy arugula pesto recipe with walnuts is perfect on pasta, bread, or veggies.
Add the ARUGULA, WALNUTS, PARMESAN CHEESE, OLIVE OIL, LEMON JUICE, LEMON ZEST, GARLIC, SALT, and PEPPER to a food processor fitted with the chopping blade.
Blend until mostly smooth, scraping down the sides as needed.
Add COLD WATER, 1 tablespoon at a time, until the pesto reaches your desired consistency.
Transfer to an airtight container and refrigerate for up to 5 days or freeze for up to 3 months.

Notes
Always use fresh arugula with crisp, green leaves. Add even more nutty flavor by toasting the walnuts in a dry skillet over medium heat for 3–5 minutes. Swap in a bit of spinach, kale, or basil if you want to mellow the pepperiness. The flavor deepens by day two, making it great for make-ahead meals.
