Crock Pot French Onion Soup Recipe Notes
- This recipe calls for 3 cups of onions sliced. I had 3 medium to large onions and that easily made 3 cups. I loved using my food processor to slice the onions VERY quickly. Little known fact about me… I used to HATE food processors. THIS one totally made me change my tune. I love how easy it is to use.
- I crocked this up in my Cuisinart Multi-Cooker which has a browning setting that allowed me to sauté my onions in the until before switching it over to slow cook.
- If you don’t have a multi-cooker you can just cook your onions in a skillet and then transfer to any 4-6 quart slow cooker.

I have prepared this recipe. I didn’t care for the addition of the sugar. Yes, the addition of sugar helps to carmelize the onions, but I prefer the soup without the sugar.
Hi Virginia- Thanks for the feedback. We used sweet onions in our soup so the added sugar really didn’t bother us, but this is very good to know for folks who would prefer not to add the sugar.
There are so many types of onions…what types do you suggest to use or does it not matter? Do some produce a stronger flavor?
Hi Claudia-
We used sweet yellow onions. I would imagine that different onions will likely bring out different flavors.
Enjoy!
I always have canned chopped green chilies, canned tomatoes, canned mushroom soup.
Can you cook this on low for up to 8 hours? Or is it best to cook it on high?
Soup had a good flavor even though I didn’t add sherry since I didn’t have any. I wish I read the comments before making the soup. It tasted a little too sweet for me. it doesn’t need the sugar. Next time I will make it without. Very easy to make. Thank you ?
