This recipe takes the classic sloppy joe and infuses it with the rich, savory flavors of French onion soup. It's a quick, easy, and incredibly satisfying comfort food remix perfect for a weeknight meal or casual gathering.
Don't rush the onion caramelization; it's key to the flavor. Drain excess fat from the beef. Watch the broiler closely to prevent burning. The meat mixture can be made ahead and stored in the fridge for 3-4 days or frozen for up to 3 months; reheat before assembling on fresh buns. For a deeper flavor, add a splash of dry red wine or beef broth when adding sauces in step 4 and simmer down.
