Great alternative for baked potatoes. Each person gets their own package and can season it up for their own preference. Great beside your grilled meat.
Preheat oven to 375 degrees. Slice potatoes thinly but not all the way through, leaving slices attached at the bottom.
Place each potato on a square of foil that will cover entire potato. Stuff some onion in between the slices and a clove of garlic, if desired. Place a pat of butter and seasonings on each potato. Wrap tin foil around entire potato.
