Method
Make the packets
- Form the ground beef into 4 thin patties and season with salt and pepper, pressing evenly so the thickness is consistent.
- Lay out 4 sheets of heavy-duty aluminum foil and layer the thinly sliced potatoes and sliced onions on each one.
- Place a burger patty on top of the potato-onion layer, then add the sliced tomato slices over the meat.
- Drizzle each packet with ketchup and mustard so it seeps into the layers while cooking.
- Fold the foil into sealed packets, crimping the edges tightly so steam stays inside.
Campfire cook
- Place the packets on a campfire grate over medium heat and cook for 25-30 minutes, turning or flipping halfway through for even heating.
- Open the packets carefully and lay 1 slice of cheddar cheese on top of each hot burger filling, then reseal briefly just until the cheese melts (about 2-3 minutes).
- Let the packets cool for 5 minutes, then serve in the foil or on hamburger buns if using.
Notes
Pro tip: Thinly slice the potatoes for faster, tender cooking so the packets don’t finish with undercooked centers. Store cooked packets in the refrigerator up to 3 days; reheat in the oven or on the grate until hot. Freezing is not recommended due to texture changes in the potatoes. For a lighter option, use lean ground beef or swap in reduced-fat cheddar.
