- Pre-heat oven to 200 degrees.
- Peel onions and cut into 8 pieces, leaving root intact, so each onion is still in one piece.
- Arrange onions onto an oiled baking tray, pour a little oil over them and season with salt and pepper.
- Bake onions until they have opened like flowers, approx. 20 min.
- Add some balsamico or sherry vinegar and and spoon over some of the oil which has collected in the tray.
- Grill for another 15 minutes.
Supposed to be good with steak, but I had rucola salad with mozzarella.
