Preheat the oven. Set oven to 400°F (200°C) and line a baking sheet with parchment or foil. Drizzle lightly with oil.
1 tablespoon neutral oil
Slice the cabbage. Trim two sides so the cabbage sits flat. Cut into four or five thick steaks (about ¾–1 inch), keeping the core intact to hold them together.
1 medium cabbagem about 1500 grams
Make the sauce. In a small bowl, stir together gochujang, soy sauce (or tamari), maple syrup, garlic, and ginger until smooth.
2 tablespoon gochujang*, 4 tablespoon soy sauce, 2 tablespoon maple syrup, 1 ” piece fresh ginger, 2 cloves garlic
Season the steaks. Place cabbage steaks on the baking sheet with space between them. Brush or spoon sauce over each piece, making sure it gets into the layers.
Top it off. Sprinkle sesame seeds and scatter green onions over the cabbage.
2 tablespoon toasted sesame seeds, 3 medium green onions
Roast the cabbage. Bake for 25–30 minutes until the centers are tender and the edges are browned.
Serve. Dish up hot over rice with extra sesame seeds and onions if you like.
