Sweet Potato Casserole with Marshmallows
Recipe adapted from America's Test Kitchen

Serves 4-5

Ingredients -

1/2 stick Promise margarine
4 sweet potatoes, peeled and cut into 1-inch cubes
1 cup dark brown sugar, packed
1 1/2 teaspoons coarse salt
1/2 teaspoon ground black pepper
1/2 cup water
1 bag jumbo marshmallows

Directions -

1. Melt Promise margarine in a large pot over medium-high heat. Add the sweet potatoes, brown sugar, salt, pepper, and water; bring to a simmer. Reduce the heat to medium, cover, and cook, stirring often, until the sweet potatoes are tender (a fork should pierce a cube with very little resistance), 45 to 60 minutes.
2. Preheat oven to 350°. When the sweet potatoes are tender, use a slotted spoon to transfer the potatoes a greased 9-inch baking dish. Bring the sauce in the pot to a rapid simmer over medium-high heat. Continue simmering until sauce has reduced to a glaze, 7-10 minutes. Pour over sweet potatoes in baking dish and top with marshmallows. Bake for 10 minutes.
3. Turn broiler to high and continue baking until tops of marshmallows have browned and puffed. Remove from oven and serve immediately.
