Preheat an oven to 375 degrees. Spread the olive oil across a sheet tray. Slice whole cabbage steaks from the center of a cabbage head, each one weighing 4 oz (about ½-inch thick). Lay the cabbage steaks flat in the oil and season with the salt, pepper, red pepper, garlic, and onion powder.
Step 2
In a small bowl, whisk together the remaining ingredients. Drizzle the sticky sauce over the cabbage steaks as pictured.
Step 3
Bake the tray for 35 minutes on a center rack in the oven. Serve with a spatula to keep the steaks whole, or mix the cabbage shreds with their sticky sauce before serving.
