Instructions

Prepare the base mixture: In the crock pot, combine brown sugar, melted unsalted butter, water, ground cinnamon, and pure vanilla extract. Stir well to blend the flavors.
Add sweet potatoes and cook: Add the peeled and cubed sweet potatoes to the crock pot and stir to coat them evenly with the sugar and spice mixture. Cover with the lid and cook on high for 3½ to 4 hours or on low for 6 to 8 hours, stirring every hour to prevent burning, until the sweet potatoes are tender.
Add marshmallows and pecans: Stir in 2 cups of mini marshmallows and ½ cup of chopped pecans into the cooked sweet potatoes, mixing gently to incorporate.
Top and melt marshmallows: Sprinkle the remaining 1 cup of marshmallows and ½ cup of pecans evenly over the top of the casserole. Cover again and cook on high for an additional 10 to 15 minutes to allow the marshmallows to melt and become golden.
Cool and serve: Uncover the crock pot and let the casserole cool for about 20 minutes before serving, allowing it to set slightly for best texture.

Notes

Stirring every hour during cooking is crucial to prevent the sweet potatoes from sticking and burning on the bottom.
For a nuttier flavor, toast the pecans lightly before adding them.
You can adjust the sweetness by reducing or increasing the brown sugar to taste.
If you prefer a smoother texture, mash the sweet potatoes slightly before adding marshmallows and pecans.
This casserole can be prepared a day in advance and reheated gently in the crock pot or oven.
