Caramelize the onions
- Melt butter in a skillet and cook sliced onion over medium-low heat for 20–25 minutes, stirring occasionally, until deeply caramelized. Set aside when golden and sweet.
Brown the beef
- In the same skillet, brown the ground beef over medium-high heat until cooked through, then drain excess fat. Add minced garlic, Worcestershire sauce, ketchup, salt, and pepper and cook for 2 minutes.
Toast and broil the melts
- Butter the bread and toast it under the broiler or in a skillet until golden. Keep an eye on it so it browns without burning.
- Place the toasted bread on a baking sheet and top each slice with the beef mixture and caramelized onions. Distribute evenly so every bite has topping.
- Lay a provolone slice over the top and scatter shredded cheddar across each sandwich. Make sure the cheese covers the beef and onions.
- Broil for 2–3 minutes until cheese is melted, bubbly, and lightly browned. Serve immediately while the cheese is stretch-warm.
Notes
Pro tip: Caramelize the onions first and fully set them aside—this keeps the beef sauce from thinning and helps the onions stay jammy under the cheese. Refrigerate leftovers in a covered container for up to 3 days; reheat in a skillet over medium until hot. Freezing is not recommended because the bread texture softens after thawing. For a lighter option, use 90% lean ground beef or a turkey-beef blend.
