Step 1

Prepare a grill for high heat. Rinse off any sand and dirt from leeks and pat dry. Arrange directly on grate (no need to oil) and grill, turning every few minutes with tongs, until outsides are completely blackened (leeks should start to soften and may begin to release some juices), 12–16 minutes.

Step 2

Transfer leeks to a cutting board and let rest 10 minutes (the interiors will continue to steam and get even softer as they cool).

Step 3

While the leeks are resting, whisk vinegar and honey in a small bowl until honey dissolves. Set dressing aside.

Step 4

Cut leeks on a diagonal into 1½"–2" pieces. Transfer to a medium bowl and toss with 2 Tbsp. oil; season with salt.

Step 5

Transfer leeks to a platter and spoon reserved dressing over. Drizzle with more oil and season with pepper.
