Grilled Radicchio with Lemon-Hazelnut Dressing

Ingredients

• 1/4 cup plus 2 tablespoons hazelnuts
• 1/4 cup fresh lemon juice
• 1/4 cup extra-virgin olive oil, plus more for brushing
• 2 tablespoons freshly grated Parmigiano-Reggiano cheese
• Kosher salt
• Freshly ground pepper
• Three 6-ounce heads of radicchio, halved through the core

Steps

1. In a skillet, toast the hazelnuts over moderate heat, shaking the pan, until fragrant, 5 minutes. Transfer the nuts to a clean towel and rub off the skins. Coarsely chop 1/4 cup of the hazelnuts; finely grind the remaining 2 tablespoons of hazelnuts.
2. In a medium bowl, whisk the lemon juice with the 1/4 cup of olive oil, the cheese and the 2 tablespoons of finely ground hazelnuts. Season the dressing with salt and pepper.
3. Light a grill. Brush the radicchio halves with oil and season with salt and pepper. Grill over moderately high heat, turning, until the edges are lightly charred, 4 minutes. Transfer to a platter and let cool slightly. Spoon the dressing on top, sprinkle with the chopped hazelnuts and serve.
