Main Ingredients
- Cooking spray
- 4 lb. sweet potatoes, peeled and chopped into medium cubes
- 4 Tbsp. melted butter
- 2 cups packed brown sugar
- 1 tsp. ground cinnamon
- 1/2 tsp. pure vanilla extract
- 1/4 tsp. ground nutmeg (optional)
- Pinch kosher salt
Topping
- 1 1/2 cups mini marshmallows
- 1/2 cup whole pecans
Instructions
- Prepare the Crockpot: Grease the slow cooker bowl thoroughly with cooking spray to prevent sticking and add the peeled and chopped sweet potatoes evenly into the bowl.
- Mix and Coat: In a medium bowl, whisk together the melted butter, brown sugar, ground cinnamon, pure vanilla extract, ground nutmeg if using, and a pinch of kosher salt until fully combined. Pour this mixture over the sweet potatoes and toss gently until the sweet potatoes are completely coated with the flavorful mixture.
- Cook the Sweet Potatoes: Cover the slow cooker and cook on high heat for 4 hours. Stir the mixture every hour to ensure even cooking and coating of the sweet potatoes with the buttery sugar flavor.
- Add Toppings and Finish Cooking: Remove the lid from the slow cooker. Evenly sprinkle the mini marshmallows and whole pecans over the cooked sweet potato mixture. Cover again and cook on high for an additional 10 minutes or until the marshmallows have melted and become slightly golden.
- Serve Warm: Once the marshmallows are melted and the pecans toasted, your sweet potato casserole is ready to be served. Enjoy as a delicious and festive side dish.
Notes
- For a nuttier flavor, you can toast the pecans lightly before adding them as topping.
- If you prefer less sweetness, reduce the brown sugar to 1 1/2 cups.
- Stirring every hour during cooking prevents the sweet potatoes from sticking and ensures even flavor distribution.
- Using mini marshmallows helps them melt evenly and blend well with the casserole.
- This dish can be prepared a day ahead; refrigerate after cooking and reheat in the slow cooker before serving.
