Slow Cooker Caramelized Onions

  • Cooking Time:

    12–14 hours
  • Servings:



3 lb. Vidalia or oth­er sweet onions, peeled and sliced
1 stick of but­ter

Dust off that small crock to make these deca­dent Slow Cook­er Caramelized Onions; if you have a lot of onions on hand, this recipe is eas­i­ly dou­bled and can be frozen for future use!

  1. Place the onions and but­ter in the insert of the slow cook­er, cov­er, and cook on LOW for 12 to 14 hours, until the onions are deep brown and very soft.
  2. It’s almost impos­si­ble to over­cook these; make sure to let the onions cook until they are mahogany col­ored.
  3. Drain onions, but reserve liq­uid.  Use onions to top steak, burg­ers, or add to soups or stews, or freeze.

NOTE:  Reserved onion-fla­vored but­ter is great to use for saute­ing oth­er veg­eta­bles, or adding to pota­to dish­es!

Hap­py Crock­ing!

I have a lot of onions in the gar­den that I will have to use up soon. Thanks for this!! Pin­ning it!


I’m just curi­ous: what do you do with the reserved liq­uid? If I was going to freeze them, would I put some liq­uid into the bags?
