Sunday Slow Cooker:  French Onion Soup

It’s funny how you forget about food you really love sometimes. It sneaks off into some far expanse of your brain and until you see it, or in this case smell it, you forget about it entirely. This is what happened to me with French Onion soup until a few days ago when I smelled it emanating from a neighbor’s apartment, and then it all came back – the deep and rich onion flavor, crunchy bread, and melty cheese. Yum. I needed some immediately. However instead of immediately, I settled for about 8 hours later with this delicious crockpot version that’s perfect for a cold night.

    This was AMAZING!!!! I hadn’t really tried it before, but now am hooked. Doubled recipe as I have a large crock pot, and no fresh thyme (used 1.5 tsp dried) or balsamic (used apple cider vinegar) but turned out great. So….delicious…..!

    This was amazing! Cut the recipe in half just to make sure that I would like it and oh yeah, I will be making the full recipe this week. Thank you for a terrific recipe! Delicious!

    I would love to make this for my family. Can I leave out the Worcester sauce since I’m gluten free? I can’t find it gluten free. Thank you.

      Definitely – it should still taste great.
