The first time I made this as a half recipe, I put the onion pan too high in the oven and they cooked very rapidly when uncovered. I now use the bottom rack with the smaller amount of onions in a half recipe. My husband loves this dish.
Jumbo Prawns & Balsamic-Orange Onions
From EatingWell: May/June 2008
The arrival of the first sweet onions of the season is an event to be celebrated, and this dish does just that. The onions are slow-cooked in the oven—which brings out even more sweetness—and then combined with both orange zest and juice, plus some balsamic vinegar to balance the flavors. Jumbo shrimp are added here, but sweet scallops would be delicious as well.
