Ingredients
Method
Make the patties
- Form ground beef into 4 thin patties and season with salt and pepper.
Pack the foil packets
- On each foil sheet, layer sliced potatoes and onions.
- Place a burger patty on top of the potato-onion layer.
- Add tomato slices over the patty so they steam as the packet cooks.
- Drizzle ketchup and mustard over the contents until evenly distributed.
- Fold foil into sealed packets and place on campfire grate over medium heat, with the seams facing up.
Cook and melt cheese
- Cook packets for 25-30 minutes over medium heat until potatoes are tender and beef is cooked through.
- Flip packets halfway through cooking so the bottom and top steam evenly.
- Open packets and add cheese slices directly on top of the hot beef.
- Reseal packets briefly to melt the cheese, watching for visible melt and slight bubbling.
Rest and serve
- Let packets cool for 5 minutes so the juices thicken slightly and the foil stays safer to handle.
- Serve in packets or on hamburger buns for a classic cheeseburger bite, using the opened packet contents.
Notes
Pro tip: cut potatoes very thin (or even shave them) so they cook in the 25–30 minute packet window. Refrigerate leftovers in a sealed container for up to 3 days; reheat until hot throughout. Freezing: yes, freeze the cooked packet filling without the buns for up to 2 months, then thaw and reheat. Dietary swap: use a plant-based ground beef alternative to keep the same packet cook time and get a similar texture.
