Footnotes

  • Cook's Notes:
  • Substitute butter with olive oil, if desired.
  • After 10 hours of cooking, reserved liquid can be strained and used to make soup or sauce.
  • Onions can be cooked longer for a deeper brown and more concentrated flavor, if desired. To reduce further, leave the liquid in and cook, stirring occasionally, until the onions are darker brown and the liquid is almost completely cooked off, 4 to 5 hours.
  • Easy Cleanup
  • Try using a liner in your slow cooker for easier cleanup

This was the easiest way to make carmelized onions I've ever tried. The up side was that they were perfect and tasted fantastic. The down side is that it takes 10 - 14 hours to completely carmel...

Great and easy to make. I used them in the slow cooker french onion soup recipe on this site. Started the evening before hitting the sack and in the a.m. added the rest for the soup. I would su...

I made this and the only thing is, I did it overnight and so the edges of the slow cooker got sort of black. Other than that, the onions were wonderful. I would do it again but during the day ...

Onions turned out great. Doubled the recipe and used my bigger pot on low for 10 hours. Cooked outside on deck so house wouldn't get smelly.

Update: 3 lb (not 5 lb) onions yields about 4 cups cooked.

filled my 5 quart cooker with home grown onions and they were delicious! Put them over a roast beef, on a sandwich (heated them in microwave for 30 seconds) and plan on freezing the rest for ot...
