Take your burgers from average to awesome on Father’s Day.

Caramelized onions are the easiest way to elevate just about any meal. When cooked for a long time, molasses roasted onions develop a rich, savoury sweetness that complements meats, cheeses and anything spicy. The recipe calls for a little balsamic vinegar (or cider vinegar) which balances the sweet and gives the flavour a bright edge.

Try these molasses roasted onions as a topper on beef, chicken or even salmon burgers. Leftovers can go on pizza.
