Preheat 450F. Spray 2 heavy large baking sheets with vegetable oil spray. Arrange onions in single layer on prepared sheets. Dot onions with 4 tablespoons butter, dividing equally. Season with salt and pepper. Bake until onions are dark brown on bottom, about 35 mins.
Meanwhile, boil broth in heavy large skilet over high heat until reduced to 1/2 cup, about 6 mins. Ad sugar and vinegar and whisk until sugar dissolves and mixture comes to a boil.
