The Easy Overnight Way In Your Crockpot No Watching No Stirring

Never underestimate the depth of flavor caramelized onions can add to many dishes. However, no one can deny that the process takes time. It’s a labor of love. It’s not something you can rush, so it’s not something impatient people like me want to do when mealtime looms. I wouldn’t say I like standing around and stirring, stirring. Maybe you do.

When onions caramelize through long, slow cooking, their natural sugars come out, and the onions transform into beautiful, sweet, brown, tender shreds of deliciousness. We don’t want to miss out on that, do we?

Great news! Let your crockpot do the work overnight while you sleep. There’s no watching and no stirring! Better news! You can make a big batch and freeze them to use for another day! It will speed up weeknight meal preparation without missing out on the magic only caramelized onions can bring to a dish.

If you don’t know how fabulous caramelized onions taste or wonder what to do with them, here’s a great article from the onion people themselves, The National Onion Association, “NOA,” Seven Ways To Use Caramelized Onions.

How To Wake Up To A Crockpot Full Of Delicious Caramelized Onions

Vidalia onions are ideal for caramelized onions, but any sweet onion will work. If you can’t get sweet onions, add about two tablespoons of brown sugar to the crockpot.

Peel the onions and cut them into thin wedges to make half-moon pieces.

Stir them a time or two again if you’re around, but if you don’t, it still works. After twelve hours, the onions transform into sweet, tender, brown onions that add a special kind of magic to almost any dish.

You are still golden if you let them cook for up to fourteen hours. They will be a little darker, and there will be less liquid, but they’ll be delicious.

You can use these onions immediately or cool them and keep them in the refrigerator for a week. For longer storage, please put them in freezer bags or containers and freeze them to use later. Ree Drummond, The Pioneer Woman, suggests freezing them in silicone ice cube trays so you can pop out a few to add to casseroles, soups, frittatas, pizzas, or omelets! That sounds like a great idea!

I love it when I find a time and labor-saving method for doing things in the kitchen. We are all in a hurry and try to pack so much into every day of our life. That’s what’s great about an idea like this. You can spend a few minutes while you prepare dinner or tidy up the kitchen and create something that will enhance the flavor of several upcoming meals. That’s a kitchen win!
