Preheat oven to 200º F and line two baking sheets with parchment paper or silicone baking mats.
Cut off the rind of the pineapple, using a coring knife to remove any deep-set "eyes."
Cut the pineapple in 1/2" to 1" slices. Lay flat on a cutting board and use a 1" circle cutter or a knife to remove the pineapple core from the center.
Arrange the pineapple slices on the prepared baking sheets, leaving at least 1 to 2 inches of space in between each one.
Bake in the preheated oven for up to 8 hours, flipping them and rotating the sheets about every 2-3 hours.
Once they appear well dried, turn off the oven and allow them to cool in the oven until room temperature and dry.
