Preheat oven to 400 degrees F.
In a large bowl or directly on the baking sheet, toss the sweet potatoes with butter or oil and 2T of the seasoning.
Spread sweet potatoes in single layer on baking sheet, making sure not to overcrowd. I used 2 sheets comfortably.
Bake until sweet potatoes are tender and golden brown, turning occasionally for about 25 minutes.
Set broiler to high and broil for 5 minutes watching constantly until desired crispiness is reached. Pull the top sheet out and broil the bottom baking sheet for additional 3-4 minutes.
Let cool 5 minutes before serving.
