Directions

1 Place Reynolds™ Slow Cooker Liners inside a 5- to 6 1/2 -qt slow cooker bowl. Make sure that liner fits snugly against the bottom and sides of bowl and pull the top of the liner over rim of bowl.
2 In lined slow cooker, mix onions and margarine.
3 Cover and cook on high heat setting 30 to 35 minutes or until onions begin to slightly brown around edges.
4 Mix flour, Worcestershire sauce, sugar and pepper. Stir flour mixture and broth into onions. Cover and cook on low heat setting 7 to 9 hours (or high heat setting 3 to 4 hours) or until onions are very tender.
5 Prepare Cheesy Broiled French Bread. Place 1 slice bread on top of each bowl of soup. Serve immediately.

EXPERT TIPS

Expert Tips

Serve food directly from the lined slow cooker. Once your slow cooker cools, remove the liner and throw away for easy clean up.

Here's some "broth math" to help you if don't have any ready-to-serve beef broth on hand. You can use three 10 1/2-ounce cans of condensed beef broth with 2 1/2 soup cans of water or 7 cups of your homemade beef broth. Or add 7 cups of water with 7 beef bouillon cubes or 2 heaping tablespoons of beef bouillon granules.

Vegetarians in your family? Use 4 cans of ready-to-serve vegetable broth instead of the beef broth. The color will not be a rich, deep brown, though, so Golden French Onion Soup may be a more appropriate name!

I decided to try the version where the onions were caramelized overnight in the crockpot. I ended up with very blackened and burnt onions. I think I will try this again but use only the low heat and less time. Evidently my crockkpot runs on the hot side. Something to consider if anyone else tries this method.

I am so impressed! I was doubtful that such a simple recipe could yield such good results. I used low sodium beef broth. I caramelized the onions in a fry pan before adding to the broth. I did not use flour (just not necessary). Added gruyere cheese atop toast rounds to the individual portions and it was excellent!Thanks for a great simple recipe!

I happen to have the downloaded Betty Crocker soups booklet. Here are the instructions in that booklet for the Cheesy Broiler French Bread: Set oven control to broil. Place bread slices on ungreased cookie sheet. Sprinkle with cheeses. Broil with tops 5 to 6 inches from heat 1 to 2 minutes or until cheeses are melted. Then you proceed to put them on top of the soup bowls.
