Method
Prep the patties
- Form the ground beef into 4 thin patties and season with salt and pepper.
- Set the patties aside while you prep the vegetables so everything cooks evenly in the packets.
Assemble foil packets
- On each heavy-duty aluminum foil sheet, layer the thinly sliced potatoes and sliced onions.
- Place 1 burger patty on top of the potatoes and onions, then add the sliced tomatoes on top of the patty.
- Drizzle each packet with ketchup and mustard so it soaks into the layers during cooking.
- Fold the foil into sealed packets, pressing the seams to keep steam and juices contained.
Cook on the campfire
- Place the packets on a campfire grate over medium heat.
- Cook for 25-30 minutes, flipping the packets halfway through for even browning and tender potatoes.
Melt cheese and serve
- Open each packet, add the cheddar cheese slices, and reseal briefly to melt.
- Let the packets cool for 5 minutes, then serve in packets or on hamburger buns if using.
Notes
For the best foil-packet sealing, pinch and roll the edges tightly so liquids don’t leak. Store leftovers in the refrigerator up to 3 days; reheat in foil or a covered skillet until hot through (potatoes soften further). Freezing is not recommended because the potatoes and cheese texture can change. For a lower-carb option, skip the hamburger buns and serve the packets straight from foil with extra mustard on top.
