Your Slow Cooker Works Its Magic While You Sleep

Do you love the rich, golden sweetness of perfectly caramelized onions? I sure do! Once I found this method for making caramelized onions easily, my first thought was, “Sign me up!”

Great news! Let your slow cooker do the work of making easy caramelized onions overnight while you sleep. There's no watching and no stirring! More good news! Right now is a great time to buy a slow cooker. Prices are low, and you'll have all winter to take advantage of all the amazing ways to use one!

Better news! You can make a big batch of easy caramelized onions and freeze them for another day! It will speed up weeknight meal preparation without missing out on the magic only they can bring to a dish.

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

Here are just a few things that would be great with caramelized onions added!

Never underestimate how much depth and flavor caramelized onions can bring to your cooking. I'm crazy about what they add to soups, casseroles, burgers, pizzas—you name it. But let’s be honest: traditional caramelizing is a s-l-o-w, hands-on process. It’s a labor of love… and sometimes a real test of my patience, because, you know, I have a jackrabbit brain.

If you’re like me, you don’t always have the time (or want to TAKE the time) to stand over the stove, stirring, stirring, stirring while dinner is waiting. That’s why this shortcut is such a game-changer—you’ll get that same deep, sweet flavor with a fraction of the effort.

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? Of course not!

How To Wake Up To Delicious Easy Caramelized Onions

Vidalia onions are ideal for easy caramelized onions, but any sweet onion will work. Add two tablespoons of brown sugar to the crockpot if you can't get sweet onions. Peel the onions and cut them into thin slices, then cut them into half-moon pieces.

Put the onions, butter, Worcestershire sauce, salt, and pepper in the slow cooker, cover it, and walk away! Stir them a time or two more if you're around, but if you're not, it still works.

After twelve hours and a good night's sleep, the onions transform into sweet, tender, brown ones that add 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 less liquid, but they'll be delicious.

You can use these onions immediately or cool them and refrigerate them for a week. For longer storage, please put them in freezer bags or containers and freeze them for later use. You could also freeze them in silicone ice cube trays so you can pop out a few to add to casseroles, soups, frittatas, pizzas, or omelets!

    1. Thank you! Cook them unitl they are as brown as you like! Since the moisture and sugar content varies in the onions, the cooking time can, too!

  1. I have been doing this for a long time. I love them. I put them in my steak rolls (rouladen) I'm German and mix them in with gravy. I also stuff my chicken breasts with them and carmelized onion cheese (Boar's Head from Publix) wrap a slice of bacon on each put on bed of diced dried beef and covered with sour cream and cream of mushroom soup.. everyone thinks I'm amazing.. how silly. I LOVE YOUR RECIPES AND IDEAS.. YOU'RE THE BOMB 💣 😉
