Peel and slice sweet potatoes into chip shapes. Err on the side of thinner rather than fatter slices if you want crispy chips.
Soak for 20 minutes in water. Soaking draws the excess starch out of the sweet potatoes which helps them to be crispy on the outside and soft on the inside, without burning.
Pat the sweet potato chips dry with a kitchen towel.
Pour the melted coconut oil onto the chips and coat well.
Sprinkle on the finely chopped rosemary and salt.
Place the chips on a baking sheet, ensuring there is plenty of space in between each chip.
Put the baking tray in a hot oven (200 degrees centigrade) and bake chips for 35 minutes
