S. sent me this link; what a great idea!?!? Why didn’t I think of it? We love slow cooked onions in our house but they take SO long and you need to watch them…yadayada….I had a bag of large onions from Costco I needed to use; the timing was perfect.
Slice several pounds of large onions; my 6 quart crock pot held 6-7 pounds of sliced onions.
I bought the inexpensive Progressive mandolin some time ago and LOVE it. It makes things like this a breeze…….a bit teary but almost fun as it whizzes through the onions to make nicely even slices.
Load the onions into your crock pot. Stuff them in. Put a cube of unsalted butter on top.
Lay the lid on top, tilted slightly.
Cook for 3-4 hours; now put the lid on properly. Stir as you have a mind to.
And after many more hours–eight in my case–this is what you have:
Beautiful, golden “grilled” onions–decant into jars–my crock made two full quarts–and use at will on everything from burgers to soups.
