Grilled Radicchio Pesto
Preheat grill to medium.Advertisement
Brush radicchio halves on all sides with 1 tablespoon oil. Grill the radicchio, turning once, until lightly charred and softened, 3 to 4 minutes per side. When cool enough to handle, remove the core and coarsely chop the leaves.
Place the chopped radicchio, cheese, anchovies, garlic, vinegar and pepper in a food processor. Pulse until coarsely chopped, scraping down the sides once or twice. With the motor running, add the remaining 1/3 cup oil and continue to process until well combined, scraping down the sides once or twice.
Make Ahead Tip: Cover and refrigerate for up to 3 days or freeze in an ice cube tray. Transfer frozen cubes to a sealable plastic bag. Defrost as needed.
