Method
Preparation
Wash, peel, and cut the sweet potatoes into roughly 1–1.5 inch cubes.
Place the cubed sweet potatoes in the crockpot and add 1/4 cup of water. Cover with the lid.
Cooking
Cook on HIGH for 3–4 hours or LOW for 6–8 hours, until tender.
Drain excess water if present and transfer the cooked sweet potatoes to a large mixing bowl.
Add the butter, brown sugar, maple syrup (if using), cinnamon, nutmeg, salt, and vanilla to the potatoes. Mash until smooth or slightly chunky. Stir in 2–3 tablespoons of milk or cream as needed for desired consistency.
Return the mashed sweet potatoes to the crockpot and smooth the top. Sprinkle mini marshmallows evenly over the surface.
Cover and cook on LOW for 15–20 minutes, or until marshmallows are puffed.
For a toasted top, transfer to an oven-safe dish and broil for 1–2 minutes until golden (watch closely to avoid burning).
Leftovers make great fillings for wraps or quesadillas. To avoid a watery mash, drain well before mashing. You can freeze the mashed sweet potatoes (without marshmallows) for up to 3 months.
