Peel your sweet potatoes and cut them into chunks. Place them in the pressure cooker with a splash of water.
Melt butter in a saucepan over medium heat. Stir in brown sugar, cinnamon, nutmeg, and salt until blended into a sweet syrup.
Pour the syrup over the sweet potatoes in the cooker and toss to coat all pieces.
Lock the lid on tight, making sure the sealing ring is in place, and set to high pressure for 8 minutes.
Let the cooker do a natural release for 10 minutes to soak flavors.
Carefully perform a quick release for any leftover pressure. Remove lid.
Optional: Transfer sweet potatoes to a baking dish, cover with foil, and bake at 350°F for 30 minutes. Remove foil and bake 15 more minutes for caramelized edges.
Notes
Serve hot with whipped cream or chopped nuts for a festive touch.
