Slow Cooker Caramelized Onions

    Mmmmm. There is something about sweet, soft caramelized onions.  This is a great base for a french onion soup.  You can pile them up on a juicy burger and melt a little cheese over them.  They would be great on an artisan pizza.  You could pile some up on a nice steak, or fold them into pasta or stir them into a dip. Oooooh or put them on hunks of crusty baguette and cover with cheese and broil for a minute.  French onion bruschetta anyone?!  Oh my goodness, that would be good!  I may just have to do that!!

    They are easy enough to make.  Slice the onions, Cook them nice and slow so the sugars have a chance to develop.  They get a nice brown color without getting the black scorched flavor.  It can take an hour to do it properly on the stove.  I knew I wanted some nice caramelized onions for something I was making tomorrow... so why not employ the ultimate tool for slow cooking?!  Watch out everyone... I'm busting out the slow cooker.  We'll have tasty onions ready by morning!

Slow Cooker Caramelized Onions


3 lbs yellow onions
1-2 T olive oil
1 T butter
1 T salt

  1. This feels silly to type... so feel free to roll your eyes, or skip down or whatever you have to do to not give up on me!  Cut the onions in half, cutting through the root and stem ends, not across the equator.  Remove the ends and peel off the top couple of layers.  Slice the onions going that same direction, from the root to stem, not across the grain.  This will help the slices maintain their integrity as they cook. 
  2. Place the onions in slow cooker.  I used my 6 qt insert, but a 4 qt would have been plenty.  Add the oil, butter and salt.
  3. My slow cooker seems to run a bit hot, so I set it on low.  After 1 hour, I stirred everything to make sure the oil was coating the onions and nothing was sticking. I went ahead and gave it another stir before I went to bed.  Then I let it go overnight.  About 10 hours after I started, voila!  yummy caramelized onions! 


  1. Wow! This is awesome! I love caramelized onions and I love that this is a low maintenance recipe!

  2. Hi Carlee, I'm going to have to give this a try. I would never Have thought to caramelize onions in the slow cooker, my worry would be that the slow cooker would crack as there is no liquid. I bet they taste better than pan made and how good will they taste in a hotdog or on a burger!


    1. You definitely have to give it a try! With a little salt and heat the onions give off a fair amount of liquid. Do it on a day where you can keep an eye on it if you are worried, but I've never had an issue with a crock breaking. I hope it works beautifully for you!
