CrockPot Sweet and Sour Caramelized Onions

Sweet and Sour Caramelized Onions. I like to make a big batch of this for a side dish for our Holiday table. Tastes super fancy, but is easy-peasy.
Day 300.

It is the 300th day of the year, and the day my youngest turns 4. If it wasn't for writing the day of the year each morning, I'd have no idea that every leap year her birthday falls on the 300th day. That's kind of neat.

She was awake at 5:51 this morning, hopping on her bed. Thankfully her older sister continued to sleep. She and Adam are in the living room playing with her birthday request: a toy barbecue. It has wheels, a little rotisserie complete with plastic chicken, and 'realistic' cooking sounds.

She couldn't be happier.

I made these onions last night on a whim because I had found this recipe in one of the Cooking Light magazines my mom brought over, and I liked the picture. They tasted fantastic and would be great paired with a nice juicy steak.


The Ingredients.

adapted from Jan. 2008 edition of Cooking Light, page 164
Ingredients
  • 2 pounds tiny onions (sometimes called boiler or pearl onions)
  • 1/2 cup raisins (one box)
  • 1 tablespoon butter
  • 2 tablespoons balsamic vinegar
  • 1 tablespoon sugar
  • 1/4 teaspoon kosher salt
  • 1/4 teaspoon black pepper
  • 1/4 cup pine nuts


The Directions.

I used a 6 quart crockpot, but anything 4 quarts and up will work.

Cut the top and bottom off of all of the onions and peel away the skin. If you get some of the onion and peel that off an outer layer, that's okay. It takes a while to peel the onions; make sure you're in a good mood.

Put the onions in the crockpot and toss with balsamic vinegar, salt, and pepper. Add the pat of butter and the raisins. Toss in the pine nuts.

Cover and cook on high for 2-4 hours, stirring every 45 minutes or so. I cooked ours for a bit more than 3 hours, and stirred 3 times. I wanted the onions to get brown and caramely on all sides.

Sweet and Sour Caramelized onions in the crockpot slow cooker. Great recipe for your Holiday table.


The Verdict.

Adam and I liked this a lot. This would be a great accompaniment to a holiday meal, or to bring as an addition to a potluck dinner.

It looks fancy, and tastes fancy, but is easy to throw together. The raisins plumped and took on the vinegar flavor, and the pine nuts added a bit of crunch and some smokiness.

I'm off to eat a plastic chicken. I can't wait.

    I'm so impressed that you peeled all those onions... wonder if it would work with the frozen ones? (I refuse to peel that many, myself! lol!)

    damsel, i used the frozen ones in the crockpot when i made pot roast in there and was elated because i know how aggravating and time consuming peeling them myself is. however, the onions tastes very dry and i didnt not enjoy eating them as i usually do. i honestly wont buy them again. as much as i hate to peel them, i wont bother eating the frozen ones again.

  6. This reminds me of a french onion soup for some reason. Wonder what that would be like to add some beef stock?

    Either way, it sounds REALLY good!

    OK, while this recipe holds no appeal for me, I wanted to comment.

    I just stumbled across your site (literally, using StumbleUpon). I currently have some chicken and cream of chicken soup in the crockpot right now. In about an hour I'll be adding frozen veggies, and half an hour later, spooning this mixture over biscuits.

    Anyway, I'm in love with crockpot food and I am now in love with your site.

    Are you going to be doing it again next year?

    Happy birthday to your daughter (and to you, of course....) My twins asked for paper and clipboards for their birthday (they're 6! now), and it felt a little like child abuse to actually get them what they asked for.... but I also got them the clicker-color change pens.... enough about that. If peeling the onions is a pain, I've found boiling the tiny onions for about 2 minutes allows one to cut off an end and squeeze them out of the peel (I bbq the pearl onions all summer). This looks so good!

  13. When Vidalia onions are in season, I buy 10 or 15 pounds and slice them up and toss with a little olvie oil. Throw in my 6 qt crockpot on low overnight with the lid ajar. In the morning, I have perfect carmelized onions. I pack in 2 cup portions for quick French onion soup or to use in other recipes.

    Love your site. Made the crockpot lasagna this weekend. Big hit at my house!

  14. Does this totally stink up your house? I love onions but the smell of them cooking just takes over my house and doesn't go away for days!

  15. Hi Cheryl!
    The onions smelled good while they were cooking, but I did still smell them in the air the next morning, and opened the windows to air out the house. I do that a lot, though---I am bothered by food smells more than the rest of the family. I've never made onions in the oven, so I don't know how the smell compares. This wasn't unpleasant, but it was there. eek. I'm not being very helpful, I'm sorry!

  17. I made this for a First Thanksgiving feast, used regular-sized onions, and cooked all night on low, and then turned them over in the morning, and cooked them until about 12 on low! Worked great.

    Thanks for this recipe, I just got a new crockpot, so will try this one.

    My mother used to use these onions to make pickled onions. She poured boiling water over the onions and let them sit for about 10 minutes. Makes the onions easy to peel.

  20. Thanks for this great, easy, and delicious recipe. I love onions and balsamic so was eager to try this. Made for Thanksgiving and was really pleased with the result, was yummy with the turkey and am struggling to leave the leftovers for tomorrow.

    Hi, I was wondering how many people this would serve as a side dish?

  22. I love the smell of onions baking, so I'm afraid if I were to put these in the crock pot overnight, it would keep me awake, drooling! :o/
    Sounds delicious. I, too, plan to use this as one of my sides for Thanksgiving this year. Thanks for sharing!
