Kristina's Tips
- If possible, use small fatter potatoes rather than long skinny ones. Small plump sweet potatoes tend to be less stringy than long narrow ones.
- Using an immersion blender rather than a hand masher helps to make them smooth and velvety. However, if you like a chunkier texture to your mashed potatoes, a hand masher will do the trick.

Instructions
- Place the sweet potatoes into the slow cooker, stacking them if necessary. Cover and set to low for 6 hours or high for 3 hours.
- When finished, poke the thickest sweet potato with a fork to check if it's tender. If not, continue cooking in 30 minute increments until potatoes are all fork tender. Carefully remove the sweet potatoes using tongs. Peel off the skins and discard. Place the sweet potatoes back into the slow cooker or put in a large mixing bowl.
- Mash using a potato masher or immersion blender. Add butter, milk, salt and black pepper. Using the immersion blender or masher, blend until smooth and creamy. Taste and season with additional salt and pepper if desired.
Serve warm with additional toppings or add-ins if desired (see below for suggestions).

How To Store
Store mashed sweet potatoes in the fridge for up to 7 days in an airtight container. They can be frozen for up to 6 months, then thawed and reheated in the microwave or oven. After defrosting, you likely will need to thicken them with a little cornstarch or flour to remove some of the moisture.
Recipe FAQs
Save yourself the trouble and time and skip peeling the sweet potatoes before slow cooking them. The potato skins will easily peel off once they are cooked and the potatoes will slide right out of them.
Mashed sweet potatoes can become a little watery once they sit a while. Simply stir the potatoes to mix in any extra moisture and if they are still too thin or runny, mix in a thickening agent like cornstarch, flour, or powdered milk in small increments.
Yes! Keeping mashed sweet potatoes on the "keep warm" setting is an easy way to serve them during holiday gatherings. There's no need to worry about warming them up and having them go cold before dinner, plus you'll keep other appliances available for all that bulk cooking!
To make crockpot mashed potatoes vegan, use oat milk or unsweetened almond milk instead of the dairy milk and vegan butter instead of traditional butter.
