Tried this yesterday…Took about four more hours and I recommend taking the lid off the last 4 hours so the liquid evaporates. But tastes amazing….
I use a similar recipe to make French Onion soup in the crock pot and the onions do sometimes burn. I think it helps to stir in the butter once it’s melted. Also, put a paper towel or two just under the lid to absorb some of the juices and really get a browning effect.
so if i were to make these 2 days ahead of when needed to top dogs after i cooked i would put in the fridge but then how do i heat them back up ?
Hi Melinda! You could just pop them in the microwave or stove top for a couple mins. I hope you love them!
Ooo my 5 big onions are in the slow cooker as we speak, it’s the 8th hour, the house smells delicious, the Chihuahua is going nuts, the husband is smacking his lips.. I followed Sara’s advice and at the 7th hour put a bar cloth under the lid to start absorbing liquids (also to keep juices from sputtering out and all over my kitchen counter) and soon I will take the lid off to let them saute and brown to the wonderful finish. Also stirred frequently, per Sara, and that seems to help with even browning. They are already nice and dark golden colored, and a taste test has earned four thumbs up, even at this stage. I am so pleased at how easy this was! I plan to freeze half of them, will put in ice cube tray, am curious of other experiences with freezing and how that turns out, etc. Thank you so much for this brilliant eye opening recipe! Love it!
Thank you so much for sharing Byama!
