Slow-Cooker French Onion Soup

My husband and I both really love French Onion Soup. We’ve tried a few recipes and none could quite compare to the wonderful concoction at Maspero’s in New Orleans. I found this recipe on the Food Network website and decided to give it a try. For a side dish, we made BLT sandwiches with sliced avocado. Interested? Read on!

Slow Cooker French Onion Soup


5 small yellow onions, thinly sliced
2 cans Swanson’s low sodium beef broth
2 cans Campbell’s Beef Consomme
1 packet Lipton’s Beefy Onion Soup Mix
1 loaf pumpernickel bread, cut into slices
sliced aged swiss cheese
shredded parmesan cheese
3 tablespoons butter
3 tablespoons white wine


In a large nonstick pan, saute onions in butter. When almost soft, add wine and cook for a few more minutes. Dump into a crockpot sprayed with cooking spray. Add the broths, consomme and soup mix. Cook on HIGH for 4 hours or LOW for 8 hours. When ready to serve, put soup in an oven-safe bowl and place a slice of bread and both of the cheeses on top and put under the broiler until the cheese melts.

French Onion Soup

The Verdict: Fantastic!! While it still does not compare to Maspero’s French Onion soup, this is the best I’ve had at home so far. James says it’s much better than the canned variety, less salty tasting. Be sure not to get red onions because they will make your soup sweet, which is a mistake we have made in the past. We will definitely be making this again. Soon!
