Preheat the oven to 350°F (175°C).
Place the sweet potatoes in a large pot and cover them with water.
Bring the water to a boil and cook the sweet potatoes for about 30 minutes, or until they are tender.
Remove the sweet potatoes from the pot and let them cool slightly.
Peel the sweet potatoes and slice them into 1/2-inch thick rounds.
Arrange the sweet potato slices in a lightly greased 1 1/2-quart baking dish.
In a mixing bowl, combine the applesauce, brown sugar, melted butter or margarine, and salt.
Mix until well combined.
Pour the applesauce mixture over the sweet potato slices, ensuring they are evenly coated.
Bake the sweet potatoes, uncovered, in the preheated oven for 20 minutes, or until heated through and slightly caramelized.
Serve the baked applesauce glazed sweet potatoes hot as a delightful side dish for any occasion.
