I like to make a batch of this overnight to use in whatever I'm cooking the next day. The smell of the onions slowly caramelizing overnight lends to very sweet dreams!

I made these exactly as listed and they were fantastic. I squished them down into an ice tray that I sprayed with oil and froze them, popped them out and stored them in a freezer bag. They thawed out perfectly every time I used them. Thanks Mirj!

Inturned this recipe into soup, after the onions were carmelized I added 4 cans of beef broth, some thyme and a little bit of dry sherry. Served with the usual crouton and swiss melted on the top, it was fantastic.

You cannot get any easier than this for carmelized onions. I was worried at first, I put them in the old fashioned tall crockpot. You need the surface for them to carmelize properly. I did finally turn it up on high in the am and with 3 hours PERFECT carmelized onions. I mixed them in with garlic mashed potatoes to serve with BBQ ribs. The rest will be turned in French Onion Soup. Thanks Mirj for the great recipe!!!
