The most bland soup I’ve ever encountered. No way this recipe won a contest. We LOVE French Onion soup and I’m always looking to find the best recipe. This , sadly, is not it. Don’t waste your time.

I added about 1/2 cup of red wine and extra Worcestershire and 2 cloves of minced garlic.

I found this soup to be very tasteless. Maybe if the onion had been super caramelized as another reviewer suggested that would've helped. I even added 3 extra beef boullion cubes to the mix after tasting. It still needed something so I tried a touch of thyme and a couple of tsp of cider vinegar but neither of those did much either. Onions really burn my eyes so this was a double disappointment after the burning eyes from the onions. Will try another recipe as Jason's Deli has removed their onion soup from their line-up and it was so good!

Boring, bland, flavorless. Used regular beef broth, not reduced sodium but it was still so blah. Won't make this again.

This is an excellent recipe for French onion soup. I have made it as written and it is great. I have also followed another reviewers advice and carmelized the onions in the crockpot overnight and finished it the next day with a bit of red wine. Delicious! Joyce Moynihan, Volunteer Field Editor

To the people complaining it's not vegetarian, use Vegetable broth!

I also carmelized the onions. I made the rest of the recipe as stated and it will now be my "go to" recipe.

I cut it down because it is just two of us. I didn't chop the onions but sliced them then cut then slices in half. I liked the flavor of the onions. I like the flavor the Parmesan cheese gave to it as well.

I use the slow cooker to caramelize the onions first in the slow cooker, then do the rest of the recipe so it takes me a full day to do this soup. I put the onions on overnight, add the rest in the morning and prepare as above. Sometimes I add thyme also. I want to try the idea mentioned of using cider. I'll use apple juice instead since I always have it on hand and see how it is. Sounds really unique and tasty.
