1 tbsp butter (or another tablespoon extra virgin olive oil)
1 tbsp extra virgin olive oil
salt and pepper
Heat oven to 425 degrees.
Trim the bottom and core from the cabbage. Cut the cabbage in half, crosswise. Then cut each half into three thick slices, for a total of six slices. Lay the cabbage slices in a 9x13 baking dish; it's ok if they overlap a bit.
Melt the butter in the microwave in a small dish. Stir the olive oil into the butter. With a pastry brush or a spoon, brush the cabbage with the butter and oil. Sprinkle each slice generously with salt and pepper.
Roast until the edges of the cabbage slices are brown and crispy, about 35-40 minutes.
