Preheat the oven to 400 F and line a baking sheet with parchment paper.
Wash the sweet potatoes, and line them up on a cutting board. Place chopsticks on both sides of the sweet potatoes, and make 15-20 slits in them. You can do this without chopsticks, just be careful and controlled!
Top the potatoes with coconut oil, salt, and pepper if using.
Bake in the oven for 50 minutes to an hour or until sweet potatoes are baked to liking. Remove from the oven and allow to cool slightly before serving. Top with fresh chives.
