Preheat oven to 350 degrees.
Wash and pat dry sweet potatoes. Peeling is optional. If keeping peel, simply cut off dark spots.
Slice whole sweet potatoes into circles (or wedges if preferred). Should be at least 1/4" thick. Arrange slices in a single layer on bottom of un-greased baking dish. Set aside.
Drizzle 1/4 of melted butter over slices. Flip over to coat both sides.
Cover with foil. Bake 15 minutes.
In a small bowl, combine remaining melted butter, brown sugar and nutmeg. Stir until brown sugar is dissolved.
Remove sweet potatoes from oven. Drizzle with butter and brown sugar mixture. Flip over sweet potatoes to coat both sides.
For soft texture, cover with foil. For firm texture, remove foil. Continue baking 15 minutes OR until tender.
Serve hot.
