Step 1

Adjust oven rack to upper-middle position and heat oven to 500 degrees. Quarter cabbage through core and cut each quarter into 2 wedges, leaving core intact. Arrange wedges, 1 flat side down, on rimmed baking sheet. Brush 1½ tablespoons oil on exposed cut sides of wedges and sprinkle with ½ teaspoon salt. Flip wedges so oiled sides are flush with sheet. Brush second cut sides with remaining 1½ tablespoons oil and sprinkle with pepper and remaining ½ teaspoon salt. Cover sheet tightly with aluminum foil and roast for 20 minutes.

Step 2

Remove foil (be careful of escaping steam) and continue to cook until cabbage wedges begin to brown on underside, 5 to 10 minutes. Using tongs and thin metal spatula, flip each wedge. Roast until edges are very well browned and some leaves have crisped, 5 to 10 minutes. Transfer to serving platter, season with salt and pepper to taste, and serve.
