1. Begin by thoroughly washing the sweet potatoes. Make sure there’s no dirt left on the skin.
2. Place the whole sweet potatoes into the slow cooker. They can be layered or placed next to each other, but try not to overcrowd the sweet potatoes.
3. Cover the slow cooker with its lid and set it to cook on low for about 6 to 8 hours, or on high for about 3 to 4 hours. The exact cooking time may depend on the size and number of sweet potatoes, as well as the make and model of the slow cooker. They are done when you can easily pierce them with a fork.
4. Once the sweet potatoes are tender, carefully remove them from the slow cooker. They will be hot, so it’s best to use tongs or a pair of oven mitts.
5. Split the sweet potatoes open with a knife and fluff the insides with a fork before serving.
Enjoy your slow cooker sweet potatoes as a simple yet delicious dish that can be transformed with an array of toppings to suit any taste and any meal.
