Preheat oven to 400°F (200°C). Line a baking sheet with parchment or foil. Drizzle the oil on the baking sheet evenly.
1 tablespoon oil
Cut two sides of the cabbage so that there is a flat surface on each end. Slice cabbage into four or five 2 cm to 2.5 cm steaks, leaving the stem mostly intact to hold them together.
1 cabbage
Cut each steak in half so that they are easier to fit on the baking sheet.
Place on the baking sheet, spaced evenly.
Peel and mince the garlic and ginger. Slice the green onions into 1”/2.5cm long pieces.
2 cloves garlic, 1 tablespoon ginger, 3 green onions
In a small bowl, combine the minced garlic and ginger, the miso paste, gochujang, soy sauce, and maple syrup. Stir until smooth.
2 tablespoons gochujang, 4 tablespoons soy sauce, 2 tablespoons maple syrup, 1 tablespoon miso paste
Drizzle or brush mixture on to each cabbage steak, spreading to coat evenly and get in all the cracks.
Sprinkle with sesame seeds and scatter the sliced green onion over the top and around the pieces.
2 tablespoons sesame seeds
Bake for 25-30 minutes until cabbage is tender enough to be pierced with a fork and onions are starting to brown.
Serve over rice with additional onion and sesame seeds as desired. Can be stored covered in the fridge and reheated in the oven for 10 minutes.
