Peel your potatoes and cut into one-inch cubes.
Place potatoes in a crockpot and cover with water. Season with salt and pepper. Cook on HIGH for 3-4 hours until potatoes are tender.
While potatoes are cooking, melt butter over medium-low heat. Occasionally stir the butter, allowing it to slowly brown. Keep a close eye on it to prevent it from burning. Once a browned color, remove from heat and allow to cool.
When potatoes are cooked, drain water from the crockpot. Add butter, heavy cream, and nutmeg. Mash potatoes either by hand or with a hand blender. Pour browned butter on top.
