Caramelized Onions - cooked until richly browned, it's a simple way to pull all the rich flavor from a humble ingredient

I think that a lot of cooks would agree that onions are the best flavor enhancing ingredient that we have for so many dishes.. From light and crispy onion straws to the onions that virtually disappear in soups, they have a way of making food just taste better. And Caramelized Onions are no exception. The caramelizing process leaves the onions tender and sweet, with some crisp edges here and there with an aroma that will make your mouth water. Pile them high on sandwiches, steaks or serve as a side dish. Either way, they are incredibly delicious.

Making Caramelized Onions is easy, but they do take a little bit of time. For red onions like these, I allow about 30 minutes of cooking time.. If you are using yellow or white onions, allow an extra 10 minutes for the onions to fully brown. The caramelizing onions need to be stirred every 3-5 minutes  so plan on staying in the kitchen for the full cooking time. I don’t know about you, but I can always use some extra time to take care of little things around the kitchen that I never seem to get to, like cleaning out the coffee maker or clearing a junk drawer.

How to make Caramelized Onions

  1. Slice the onions into 1/4 inch thick rings. 
  2. Over medium heat, melt the butter in a skillet on the stove.
  3. Add the onions, separating into rings. Stir to coat every ring with butter.
  4. The onions will start to reduce in volume right away and will be about a 1/4 of the original volume when they are done.
  5. Continue to cook over medium heat, stirring every 3-5 minutes until they are tender and starting to brown. Add the liquid to de-glaze the pan, using a spatula to scrape all of the crispy bits from the bottom of the pan.
  6. When the onions are browned, they are done. Remove the onions from the skillet so they stop cooking.
