French Onion Beef Sloppy Joes combine the rich, savory flavors of French onion soup with classic Sloppy Joe comfort. Sweet caramelized onions, juicy beef, melty cheese, and toasted buns make this easy sandwich a cozy, crowd-pleasing dinner.
For gluten-free, use gluten-free buns. For low-carb, serve filling over roasted veggies or in lettuce wraps. Caramelize onions slowly for best flavor. Cheese can be swapped for dairy-free alternatives. Filling can be made ahead and reheated. Toast buns well to prevent sogginess.
