Boil the sweet potatoes in a pot of water until they re fork-tender, about 15 minutes. Once done, drain them well to remove excess moisture, which helps with the casserole s texture.
Mash the sweet potatoes in a large bowl (or in the same pot you cooked them in). Use a potato masher or immersion blender for a smooth, creamy base that will serve as the heart of this dish.
Combine the brown sugar, milk, nutmeg, butter, cinnamon, vanilla, salt, and pepper into the mashed sweet potatoes. Blend everything together until it s creamy and well-mixed, ensuring every bite is bursting with flavor.
Add the lightly beaten eggs and stir to combine thoroughly. Then, spread the mixture evenly into your prepared baking dish, making sure it s nice and smooth on top.
Sprinkle the chopped pecans over the top of the sweet potato mixture. Bake for 20 minutes until warmed through, and the edges begin to firm.
Dot the top with miniature marshmallows, returning the casserole to the oven for another 7-10 minutes. Keep an eye on it until the marshmallows turn golden brown and start to caramelize.
Optional: Serve warm for the best gooey marshmallow experience!
