Ingredients
- 1 large heads of radicchio, well rinsed, outer leaves removed
- 1 large yellow onion, sliced into 1/2” intact discs
- Extra-virgin olive oil
- Sea salt or kosher salt and freshly ground black pepper
- Sherry vinegar, optional
Directions
-
Preheat a grill pan over medium-high heat.
-
Cut the radicchio into quarters taking care to leave the root end intact so that the quarters stay together. Brush olive oil liberally onto all sides of the vegetables. Sprinkle with plenty of coarse salt and pepper. Also coat the onion slices with oil, salt and pepper.
-
Grill (cut sides down first on the radicchio) until the vegetables just begin to wilt and get brown on the edges, about 1 to 2 minutes. Turn to the other cut side and grill for 1 minute longer. Lastly, grill the outside leaves of the radicchio for a moment to get attractive grill marks. Transfer these to a serving platter and serve, warm or at room temperature. You may drizzle with a little sherry wine vinegar right before serving if desired.
