Wash your potato, if u don't like skin on you can peel the potato. I don't mind eating mine with the peel.
Cut your potato
Add no stick cooking spray, I used the Pam brand but you can use any kind
I seasoned my potato with salt, dried parsley, and a little olive oil. You can season it with your favorite seasoning, if you like. Arrange your potatoes like this.
Add a ice cube in the middle of the potatoes
Fold one side of the foil
Then the other one
Fold the bottom like this
And the other end as well. Should look like this
Put in the grill, mine took about 10 mins on each side on low heat. After 10 mins turn the potatoes around
On one of my foils I forgot to put the no stick spray 1st and this is how they came out, still cooked and delicious but it was a little hard to get them out. They got stuck. Oops
And this is the one that I did put the no stick spray, enjoy with your favorite meal.
