Preheat oven to 250 degrees f. Wash and dry your sweet potatoes. Thinly slice your potatoes length-wise. 1/4- 1/3 inch wide max.
Place them on a baking sheet lined with parchment if you have it. I was all out this time so I just placed them directly on the cookie sheet. Then bake them for 3 hours, turning them over halfway through. You want them to be pretty chewy and dry. You can also use a dehydrator if you have one instead.
Store them in the fridge or freezer because if you leave them out they could get moldy.
Then the real fun begins……giving them to your dog.
