Method

step 1

Heat the oven to 200C/180C fan/gas 4. Peel the onions and slice them in half across the circumference. Put them cut-side up in a small baking dish and drizzle with 2 tbsp of the olive oil, then season with salt and pepper. Roast for 30 mins. Meanwhile heat the stock and add the miso and maple syrup. Grate the cheese into a separate bowl, then mix in the breadcrumbs and chopped sage.
step 2

After the onions have had their 30 mins, pour the stock around them and roast for another 20-40 mins, basting occasionally. The onions should be very soft, and the liquid reduced; how long this will take depends on the type of dish you use. Test after 20 mins then keep cooking if you need to.
step 3

Sprinkle the cheese mix evenly over the top of the hot onions, drizzle with 1 tbsp oil and return to the oven (or use the grill) for 3-4 mins until the cheese is bubbling. Spoon the glaze from the base of the dish on top of the onions as you serve them.
