Begin by rinsing the garlic scapes under cool, running water to remove any dirt or debris. Trim off the woody ends and any seedy pods.

In a food processor, combine the prepared garlic scapes and pulse them for about 30 seconds until a coarse paste forms. Scrape down the sides to ensure even blending.

Add olive oil, walnuts, grated Parmesan cheese, lemon juice, fresh basil, salt, and cracked black pepper. Blend on high for 30 to 60 seconds until smooth.

Taste your Garlic Scape Pesto and adjust flavors by adding more Parmesan or walnuts if desired. Blend again for a few seconds to harmonize the ingredients.

Use a cookie scoop to divide the pesto into small balls, freeze until solid, then transfer to airtight bags, or store in an airtight container in the fridge for up to a week.
