I guess this post should really have been entitled "Sugar Roasted Leeks, Onions, and Shallots" but that doesn't have the same ring to it. I'm not giving exact amount for this recipe as I do different amounts each time based on the vegetables I have to hand.
Leeks, peeled and chopped into inch long pieces
Onions, peeled and quartered
Red Onions, peeled and quartered
Shallots, just peeled
Place the vegetables in a roasting tin. Drizzle with the olive oil and then sprinkle a generous amount of demerara sugar over all the vegetables.
Place the roasting tin in an oven at 200C (400F) for 35 to 40 minutes. Be careful when serving as the oil and sugar in the base of the pan gets very hot.
