How to make grilled potato packets
Begin by preparing a piece of heavy duty foil. It should be 18 inches x 24 inches. I prefer to use heavy-duty foil like this roll of tinfoil. If all you have is regular strength, double up so that the packet is thicker. This will help prevent burning.
Slice the potatoes with sharp knife, and onions if using, about ¼ inch thick. Cut the onions first so that the potatoes don't turn brown while waiting.
Place the potatoes, onions, salt and pepper into the middle of the piece of foil. Mix well. Slice the butter into pats and dot them around the potato mixture.
Create a pouch around the mix, making sure to seal all the edges completely.
Here is a step-by-step tutorial on how to fold a foil pack.
Place on a preheated grill over a medium-high heat flame or coals for 25-30 minutes flipping halfway through. Use a wide grill spatula for flipping and removing from the grill.
Allow the packet to cool for at least 5 minutes before opening. Using hot pads, carefully open the sides first and then the center, being sure not to let the steam burn you.
Hint: Keep an area of the grill turned off for indirect heat. If the packets feel like they are cooking too quickly on the outside, then move them over to the side without direct flame and allow them to continue to steam.
Substitutions
Could be variations, substitutions, storage, what to serve with, solving a common problem, answering a top question. Look at data for this keyword.
- Potatoes: : Try Russet potatoes, red potatoes, baby potatoes, fingerlings, or Yukon golds.
- Onions: White, yellow, or sweet onions are delicious. In our experience red onions discolor the potatoes, so stay away from those.
- Fresh Garlic: A couple cloves of minced garlic can be sprinkled on before mixing.
- Fresh Herbs: We like thyme, parsley, rosemary, sage, chives, or green onions.
- Seasonings: Mix it up with seasoning salt, cajun spices, Italian herbs, garlic powder or garlic salt.
How long to cook potatoes in foil?
On a grill - For a charcoal grill, gas grill, or Traeger these potatoes will need 25-30 minutes. The most important thing is to remember to set the temperature to medium to medium-high. If using a coals, I like to make sure the grill grates are about 5-6 inches below the packets.
For the oven - Place sealed foil pouch on a baking sheet and bake for 45 minutes at 350ºF. This will work, but is our least favorite method.
Over the fire - This method is the trickiest. Look for the bed of coals to be medium to medium hot. If they are too hot the potatoes on the bottom will burn quickly before the middle is done. Place the packets on a grill grate that is about 6 inches above the coals. Cook for 25-35 minutes, depending on how hot the coals are.
FAQ
Grilled potato sliced should be about ¼ inch thick. If they are too thick they will take too long to cook through. If they are too thin they will cook through before getting crispy.
For these campfire-style foil potato packets they should not be boiled first. The magic of the tightly sealed pouch is that it helps to steam them on the inside while crimping the edges. Super easy with no need to precook!
Tips and tricks
- Spread out the potatoes on the foil so they are no more than an inch thick. Thicker than that and the middles ones won't cook.
- Move to indirect heat if the packets are cooking a little too fast.
- Use both olive oil and butter for optimal flavor.
