The rich, savoury flavour of molasses roasted onions complements any meal – meat or vegetable.

This humble vegetable can elevate any meal – meat or vegetable.

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, roasted vegetables 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 burger topper, serve them with stuffed mushrooms and alongside roasted squash or sweet potatoes. Leftovers can go on pizza.

    Where are the recipes you can used with cooking molasses… I only read fancy molasses to used every where… ??

      Hi Gilles, This website is devoted to fancy molasses recipes because that is our molasses product that is available in most grocery stores across Canada. If you enjoy the flavour of cooking molasses then any recipe on this website would be suitable to make with cooking molasses. As a general recommendation, if I’m baking with cooking molasses I choose recipes that call for no more than 1/4 cup of molasses.
