We ADORE caramelized onions in our household. But it takes a bit of work and a LOT of time to make them the traditional way. So when I came across a way to make them in the Crock*Pot I pinned the method right away. You can find the site I originally found this method at HERE. This week I decided to make it my mission to make them because I haven't done a Crock*Pot recipe in awhile, and onions were on sale. I got 4lbs of sweet onions (about 10 medium onions) for $1.98. So this was easy, cheap, and we have a mess of caramelized onions to use on steak sandwiches, in french onion soup, or to make a tart with. Yum!
***Note - I use a mandolin to slice my onions. This is the easiest and fastest way to do this job.
***Secondary Note - The fumes that come off this many onions when prepping can be brutal. I was crying like no ones business, but that's to be expected. However, we have a brand new kitten and I had no idea the fumes would affect him, but they did. The poor little guy was crying and we had to move him outside for a while. So I recommend that if you have pets and/or kids, you prep your onions in a well ventilated area, with doors and/or windows open. Or have them stay in another room while prepping.
Crock*Pot Caramelized Onions
Spray inside of slow cooker with cooking spray. Place in sliced onions. Drizzle with butter (or olive oil). Sprinkle on salt. Turn slow cooker to the low setting. After 4 hours, stir in sugar. After 8 hours, stir again. Onions will be perfectly sweet, soft, and caramelized at 12 hours. ***This seems like a lot of time But if you do the first 4 hours before you go to bed and then let them cook the remaining 8 while you're sleeping, it's pretty efficient.
