Method
Form patties and season
- Divide the ground beef into 4 portions and form into thin patties, seasoning both sides with salt and pepper.
- Keep patties ready while you prep the vegetables for layering in the foil packets.
Assemble foil packets
- Lay out 4 sheets of heavy-duty aluminum foil and layer sliced potatoes, onions, and bell peppers on each sheet.
- Place one beef patty on top of the vegetables and add 1 tbsp butter on top of each patty.
- Fold the foil tightly into sealed packets so steam stays inside and the layers can cook evenly.
Cook on campfire grate
- Place packets on a campfire grate over medium heat for 20–25 minutes, flipping halfway so the patties cook through.
- Keep the foil packets sealed during cooking and watch for steady heat rather than flare-ups.
Melt cheese and rest
- Open each packet, add 1 cheese slice to the burger, then reseal briefly just until the cheese melts.
- Let the packets cool for 5 minutes before serving directly from the foil.
Notes
Pro tip: slice the potatoes thin so they tenderize inside the foil within the 20–25 minute window. Store leftovers in the refrigerator up to 3 days (freeze up to 2 months; thaw in the fridge overnight and rewarm in a skillet covered until hot). For a lighter option, use 90% lean or leaner ground beef—cooking time should stay about the same.
