Method
Build the foil packet
- Layer the thinly sliced potatoes and sliced onion on a large double-layer of heavy-duty aluminum foil, spreading into an even mound with no big gaps.
- Dot the potato-onion layer with butter cubes so the fat distributes across the packet.
- Season evenly with garlic powder, paprika, salt, and pepper, aiming for full coverage of the exposed surfaces.
- Fold the foil into a sealed packet, pressing along the edges so steam stays inside.
Campfire cook
- Place the sealed packet on a campfire grate over medium heat for 25-30 minutes, cooking undisturbed so the potatoes soften through.
- Flip the packet halfway through the cook time so the slices brown more evenly on both sides.
Melt cheese and serve
- Open the packet (carefully for steam) and sprinkle with shredded cheddar cheese if desired.
- Reseal and cook the opened-yet-sealed packet for 2 minutes, just until the cheese melts and looks glossy.
- Serve hot directly from the packet.
Notes
Pro tip: cut potatoes quite thin so they cook through in the full 25-30 minutes without drying out. Store leftovers in an airtight container in the refrigerator up to 3 days; reheat in a covered skillet until hot. Freezing isn’t recommended because foil-packed potatoes can turn mealy after thawing. For a dairy-free swap, use olive oil instead of butter and omit the cheddar or use a plant-based shredded cheese that melts well.
