Preheat oven to 375°F (190°C). Peel and cube sweet potatoes, cutting them into 3/4" cubes. Arrange cubed sweet potatoes in a lightly greased 9x13" baking pan.

In a small saucepan over medium heat, combine butter, brown sugar, cinnamon, nutmeg, ginger, and salt. Bring to a boil, whisking together until well blended. Remove from heat and pour over sweet potatoes. Stir to coat.

Cover dish tightly with foil and place in the oven. Bake for 45 minutes. Remove from oven, uncover, and stir again to coat well with sauce.

Continue baking uncovered until sweet potatoes are tender, about 15-20 minutes. Remove from oven when done and serve!

For roasted sweet potatoes, preheat oven to 425°F (220°C), peel, and cut sweet potatoes into 1-inch cubes. Toss with olive oil, Italian seasoning, salt, and pepper. Bake for 30 minutes, turning halfway through. Serve hot!
