Surprizingly good--even my husband, who is a french onion soup snob, liked it. I was surprized that a french onion soup could be this good from a crockpot. I used a quality brand beef stock, I added some fresh ground pepper when I sauteed the onions/garlic and I made my own homemade croutons. Next time, I think I would use all sweets and maybe add one more onion but that's honestly a personal preferance, not a reflection of the recipe. I'd make this again.

This was tasty! It was definitely easier than making onion soup the traditional way...I did feel that it was a bit on the thin side, though. I only used sweet onion and more than called for. The flavor was nice! This won't replace my usual onion soup recipe, but for quickness and ease, this was great! I may even try to use this method w/ my usual recipe, b/c the concept is just great. I made my own 'croutons', using sliced baguette that I toasted on each side and then rubbed w/ a clove of fresh garlic, and I used swiss just b/c that's what I always use when I make onion soup. All in all this was good and I would def make it again, with a few minor adjustments! Thanks for sharing. :)
