WW Friendly Skinny Slow Cooker Beefy French Onion Soup Recipe
Here’s a hearty, full-flavored soup with beef, onions, and mushrooms in a rich beef broth that is as easy as it is tasty.
Delicious when topped with cheesy toasted French bread, this Easy Beefy French Onion Soup was a big hit when I served it for dinner last night.

I love using my crock-pot (affiliate link) to make hearty main dish soups like this slow cooker beefy french onion soup.
Just a few minutes of work early in the day allows us to enjoy a quick and easy dinner that’s ready-and-waiting when we are.
Recipe Notes
Softening the onions and browning the meat and mushrooms in a skillet before tossing it into your crock pot adds a lot of extra color and flavor.
But, if it seems like too much effort, skip it and this skinny beefy french onion soup will still taste great.

Enjoying French onion soup at home became so much easier when I learned the secret to no more burnt hands trying to maneuver bowls of hot soup in and out of the broiler.
Make the cheese croutons for this French onion soup by separately by toasting the cheese-topped bread under the broiler and then float it on top of the soup, instead of attempting to broil it all together in the oven!
