  • 3 lbs Yukon gold potatoes
  • 1 large onion
  • 2 Tbsp olive oil
  • 1 tsp garlic powder
  • 1 tsp Nature’s seasoning or ½ teaspoon salt, ¼ teaspoon pepper and ¼ teaspoon onion powder


  • Preheat your grill to medium heat and slice your potatoes and onions. You want to slice the potatoes to about ¼ inch thick.
  • Make the foil packet by placing one long rectangle of foil over a smaller square piece that can wrap around the top. Make sure your large rectangle is able to completely cover your potatoes.
  • Add the potatoes and onions to the foil and pour on the olive oil plus the seasonings. Toss together to coat.
  • Fold the longer rectangle up at the ends and then the square over the middle to seal the packet. I do like to leave a small slit open to allow the air to pass through. You can do that or seal it completely.
  • Place the packet carefully on the grill. Cook for 25-30 minutes. Check your potatoes by piercing them with a fork. When they are fork tender they are done.
  • Remove, top with sour cream and chives and enjoy.


What kind of potatoes should I use?
The best type of potatoes to grill is either a Yukon Gold or Red Potato. They will hold up their shape when you grill and not turn into mush. A russet would also work.
Can I add more vegetables?
Yes! Just make sure to thinly slice them so they cook quickly. A great addition would be peppers! Other ideas would be sliced carrots, mushrooms etc.
Can I use different seasonings?
Yes! You could switch out the seasonings and use a ranch seasoning or add a dish of chili powder. Our Montreal Steak Seasoning would be another great choice!
What should I top the potatoes with?
We topped the potatoes with a dollop of sour cream and chives. Freshly grated cheese is a great idea or even salsa, green onions etc. would be delicious.
Can I make these in the oven?
Yes! Preheat the oven to 350 degrees F. Bake them around 40 minutes or until the potatoes are tender.
Can I make these over the campfire?
Yes! Build a campfire and when the coals are hot place the foil packet on the coals (not the flames!). Cook for about 20-30 minutes or until potatoes are tender. Make sure to turn the packet a few times to cook evenly.
