Pro Tips
These little tweaks make the difference between a good sloppy joe and a memorable one. I love watching the steam rise as the sauce thickens—it feels like the kitchen is giving you a gentle hug. So, when you plate the sandwiches, let them rest for a minute; the flavors settle and the buns stay pleasantly soft.

Instructions
Heat butter in a large skillet over medium‑low heat, add the sliced onions, and cook gently, stirring occasionally, until they turn a deep golden brown, about 12‑15 minutes.
Remove half of the onions for garnish, then increase heat to medium and add the ground beef, breaking it up with a spoon; brown in batches to avoid steaming, about 5‑7 minutes.
Stir in the beef broth, Worcestershire sauce, balsamic vinegar, brown sugar, and a pinch of salt and pepper; let the mixture simmer until the sauce thickens and coats the meat, roughly 5 minutes.
Toast the buns lightly, then spoon generous portions of the beef‑onion mixture onto each bun, topping with the reserved onions, optional cheese, and a sprinkle of thyme.
