Preheat your oven to 425°F. Line a baking sheet with parchment paper for easy cleanup.
Arrange the cabbage wedges on the prepared baking sheet.
Brush each wedge with olive oil, coating both sides.
Season generously with salt and black pepper.
Roast for 12 to 15 minutes. Flip each wedge, then continue roasting for another 10 to 12 minutes until the edges are crispy and browned and the centers are tender.
Serve hot as a side with your favorite main course.
