Preheat oven to 400 degrees.
Brush a rimmed baking sheet with 1 tablespoon extra-virgin olive oil.
Place 1 medium head green cabbage, cut into 1-inch-thick rounds, in a single layer on sheet and brush with 2 EVOO tablespoons.
Season with coarse salt and ground pepper and sprinkle with 1 teaspoon caraway or fennel seeds.
Roast until cabbage is tender and edges are golden, 40 to 45 minutes.
