Nutrition and Calories in Caramelized Onions

Not all sautéed onions are made the same way. Most often they are packed with butter or oil and so much white wine your wine glass is crying.

Skip the wine and use Worcestershire sauce… it’s a more traditional way to make these sticky sweet onions, and you won’t be adding 100’s of calories as you would with wine.

We used Olive oil spray in place of butter or loads of oil. It allows us to use a find mist of oil, as apposed to a large drizzle. And these onions let off enough liquid that they don’t need so much oil.
