Step-by-Step Instructions

1. Prepare the Sweet Potatoes
In a large pot, boil the cubed sweet potatoes in salted water until tender, approximately 15–20 minutes. Drain and let them cool for a few minutes until they are manageable.

2. Mash the Sweet Potatoes
Transfer the sweet potatoes into a mixing bowl. Using a potato masher or electric mixer, blend until creamy and smooth.

3. Mix in Ingredients
To the mashed sweet potatoes, add the softened butter, brown sugar, milk, eggs, vanilla extract, cinnamon, nutmeg, and salt. Mix until all ingredients are well combined and the mixture is fluffy.

4. Transfer to Baking Dish
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish and pour the sweet potato mixture into it, spreading it evenly.

5. Bake
Place the casserole in the preheated oven and bake for approximately 45 minutes. For the last 10 minutes, if desired, sprinkle mini marshmallows on top and continue baking until golden brown and puffy.
