Directions

Preheat oven to 350°. Place sweet potatoes and carrots in a large saucepan; add water to cover. Bring to a boil. Reduce heat; cook, covered, just until tender, 10-20 minutes. Drain; transfer to a blender or food processor. Working in batches, pulse with the next 6 ingredients until smooth. Pour into a greased 2-1/2-qt. baking dish.
Combine topping ingredients; sprinkle over sweet potato mixture. Bake, covered, for 30 minutes. Uncover; bake until heated through, 15-20 minutes longer.
