    Barbara, I know that some slow cookers get much hotter than others. But sorry this did not work out for you. Maybe click through to Mountain Mama Cooks and ask the blogger who created the recipe. She might be able to clarify more about how she made it work.

    I’m not sure what may have gone wrong with this recipe. For the first two hours I tried to caramelize the onions to a golden brown with the lid on the slow cooker and all I got was soft onions and onion juice. Then I thought maybe I should have had the lid off, so for another two and a half hours I had the lid off. No difference. I gave up and just added the broth and other ingredients. Not sure how you can caramelize and make onions golden in a slow cooker.

    Shirley doesn't it look good! I recently had lunch with two of my sisters in a very nice restaurant in SLC. They both had French Onion Soup and of course I was trying to diet and had a salad. When the soup came I regretted so much not ordering it, so maybe I need to make my own!

    That looks terrific! I really miss French Onion soup. It's a rarity to be able to get it gluten free when eating out. It's easy to serve this gluten free, just by using gf bread. And I happen to have some gf baguettes on hand. 😉

    Thanks, Kalyn and Kelley!
