Preheat oven to 425 F (218 C) and line a large baking sheet with parchment paper (use more baking sheets if making a larger batch).
Add thinly sliced cabbage to the prepared baking sheet, drizzle with oil, and toss to evenly coat. Arrange in a single layer, sprinkle with a healthy pinch each sea salt and black pepper (optional), and with curry powder (optional). If using curry powder, toss once more to evenly coat cabbage with spices.
Bake for 16-20 minutes or until golden brown and tender. The time it takes will depend on how thinly the cabbage is sliced. Toss at the halfway point to encourage even browning.
Taste test and add more salt if desired. Enjoy as a simple side dish or in bowls, salads, soups, and more.
Best when fresh. Leftovers will keep for 2-3 days in a sealed container in the refrigerator. Not freezer friendly.
