Original recipe makes 6



Pour bouillon in crockpot; cover and set on high. Cook onions slowly in large skillet in margarine; cover and let cook for about 15 minutes. Uncover and add salt, sugar and flour. Stir well. Add to stock in crockpot. Cover and cook on low for 6-8 hours. Add sherry anytime during the last 2-3 hours of cooking. NOTE: The sugar aids the browning process. Place a slice of french bread in each serving dish. Place a slice of jack, mozzarella or similar cheese over the bread. Pour hot soup over this combination. The result is wonderful!!!!

I used a little less sugar and paired it with homemade French bread! This was wonderful!

This recipe came out in both colored text, very nicely. For my palate it was too sweet. You may want to adjust sweetness to your own taste.

Great. Even better if you top with a thin slice of french bread, add a little mozzarella cheese, add a dash of parmesan cheese and broil until golden brown and bubbly. Also subbed Pinot for the sherry and served the soup with the wine. I liked the level of sweetness, but then again some of my favorite onion soup is sweet Maui onion soup so maybe it just reminds me of that.

This came out great!!! I read the reviews prior to making it so I used less sugar, that seemed to be the theme of the reviews. The only thing I'll do different is cut the onion thicker so it has that restaurant quality.

I made this according to the recipe and the comments below with less sugar. I added the sherry. I added a couple of cloves of crushed garlic part way through. I like the idea of the bread and cheese at the bottom of the bowl

I agree with it being a little too sweet, so i'll just try 2 T. sugar next time. I love my french onion soup with a slice of swiss cheese.

It turned out to be a little sweet, but not too much. Otherwise, a very good recipe.

Make sure to let it stay in the crockpot for the entire specified time. I tried to rush it the second time and it didn't come out as good.
