There are so many ways to make caramelized onions but this is our favourite. You can make a big batch and freeze them in 1/2 cup portions so that you always have some on hand. They are a great addition to pizzas, grilled cheese sandwiches, on top of steaks or even meatloaf, as a garnish on soups, in omelets or quiche and lots more.
Makes about 2 cups
Heat oil in a large deep skillet. Cook onions until wilted and starting to brown. Stir occasionally.¬†Add sugar, vinegar, salt and pepper. Cook gently 15 to 25 minutes until richly caramelized. Cool.
