Slow Cooker French Onion Soup
Need some inspiration for a mid-week meal? We’ve got a classic favorite that you will love once you see how easy it is to prepare. Our slow cooker French onion soup is simple and delicious!
While you prepare this recipe, don’t be intimidated by the onions practically overflowing from the slow cooker. They will cook down to 20 percent of their volume over the course of 8-9 hours. The slow cooker will caramelize the onions so the finished product will be beefy and sweet, not oniony.
One of the best parts of this soup is the top. Don’t leave the kitchen for last step when the soup is under the broiler. The cheese will become melted and bubbly–but should only take 30 seconds, so don’t take your eyes off the prize! Enjoy!
Serve this soup recipe in a fancy homemade bread bowl!
