Preheat oven to 325ºF. Place shredded or flaked coconut evenly on a large baking sheet that has been lined with a Silpat baking mat or parchment paper. Put the baking sheet on the middle rack and bake for 3 minutes. After 3 minutes, open the oven and gently stir the coconut with a spatula. Bake until the coconut is golden brown, about 3–4 more minutes. Remove from oven and cool completely. Note: Make sure you keep an eye on the toasted coconut. Once it starts to toast, it toasts quickly!
