Step 1

Arrange a rack in the middle of the oven and heat to 450°F.

Step 2

Cut the cabbage through the core into 8 wedges. Lay the wedges cut-side down on a large roasting pan or baking sheet and drizzle very lightly with oil. Season generously with salt and pepper.

Step 3

Roast for 15 minutes. Meanwhile, make the vinaigrette: Whisk all the ingredients together in a small bowl until combined; set aside.

Step 4

Flip the cabbage wedges and roast until browned at the edges, about 15 minutes more. If the edges aren't browned enough for your taste, put the cabbage back in for 5-minute increments until they are. Drizzle with the vinaigrette and serve immediately.
