French onion soup is a classic. Burgers are a classic. Put them together, and you’ve got one incredible slow cooker meal.

These burger steaks capture everything you love about French onion soup—sweet caramelized onions, rich beefy gravy, and melty cheese vibes—layered over juicy ground beef patties. The slow cooker does all the heavy lifting, turning simple ingredients into a dish that tastes like it came straight from a cozy bistro.

Best of all? You don’t need to spend an hour caramelizing onions on the stovetop. The slow cooker takes care of that too, slowly transforming sliced onions into jammy, golden perfection while the patties soak in savory French onion gravy.
