On the river, Chef Andrae Bopp wraps whole sweet Walla Walla onions in foil and tosses them into the coals of the campfire to roast and caramelize; here we’ve adapted his recipe for your home grill. Don’t skip the zippy honey-vinegar drizzle—it coaxes out even more flavor from the sweet onions and balances the blue cheese.

Ingredients

  • 2 large Walla Walla or sweet onions, each cut into 4 wedges (root end left intact)

  • 2 tablespoons plus 2 teaspoons aged sherry vinegar, divided

  • 4 teaspoons extra-virgin olive oil

  • 1 teaspoon fine sea salt

  • 1/2 teaspoon ground black pepper

  • 10 ounces blue cheese, softened (about 2 1/2 cups)

  • 1 baguette, sliced and grilled or toasted

  • 1/4 cup honey

  • 1/2 cup toasted pine nuts

  • Fresh thyme leaves, for garnish

Directions

  1. Place onion wedges, cut sides up, on a rimmed baking sheet. Drizzle evenly with 2 tablespoons vinegar and oil; sprinkle evenly with salt and pepper.

  2. Preheat a gas grill to medium (350°F to 400°F) on one side, or push hot coals to one side of a charcoal grill. Place onion wedges, cut sides up, on oiled grates over unlit side of grill. Grill, covered, 20 minutes. Turn onions onto one cut side; grill, covered, until grill marks form, about 10 minutes. Turn onions onto remaining cut side; grill, covered, until tender, about 10 minutes. Remove from heat.

  3. Let onions cool slightly; discard any outer charred pieces. Finely chop 2 onion wedges; stir together with softened blue cheese in a medium bowl until combined. Cut remaining onion wedges lengthwise into thinner wedges, and separate into petals. Spread blue cheese mixture evenly over baguette slices; top with onion petals. Whisk together honey and remaining 2 teaspoons vinegar; drizzle over crostini. Sprinkle with pine nuts; garnish with thyme leaves.
