Method
Build the foil packet
- Layer the thinly sliced potatoes and sliced onion on a large double-layer of heavy-duty aluminum foil so the slices lie mostly flat for even cooking. Keep the foil centered and ready to fold into a sealed packet.
- Dot the potatoes with cubed butter and season evenly with garlic powder, paprika, salt, and pepper. Make sure seasoning reaches the onion too so every forkful tastes balanced.
- Fold the foil into a sealed packet, pressing the edges firmly to prevent steam from escaping. Leave a little space above the food so the packet doesn’t burst as it heats.
Cook over the campfire
- Place the sealed packet on a campfire grate over medium heat for 25 to 30 minutes. Set it so the packet is heated steadily rather than directly flamed.
- Flip the packet halfway through cooking for more even browning and tender steaming. Return it to the grate promptly and keep the heat at medium.
Finish and serve
- Open the packet carefully and sprinkle with shredded cheddar cheese if desired. Reseal the foil packet right away to trap the heat for melting.
- Reseal and cook for 2 minutes more to melt the cheddar, watching for a glossy, gooey top. Serve hot directly from the packet so the potatoes stay steamy and flavorful.
Notes
Pro tip: slice potatoes thin and fairly uniform so they cook through in the same 25–30 minute window. Refrigerate leftovers in a sealed container for up to 3 days; rewarm in the foil or a skillet until hot. Freezing is not recommended for best texture. For a lighter option, use plant-based butter instead of regular butter for a similar melt and mouthfeel.
