I chose to cut these purple sweet potatoes into bite-sized pieces. This helps speed up the roasting and results in sweet potatoes that are tender on the inside and lightly crisp on the outside.
If you want to keep the dishes used to a minimum when making this dish, you can skip putting the cut-up sweet potatoes into a bowl. Instead, pile them onto a baking dish and toss the spices and oil onto them. Then toss them with the spices and oil so everything is distributed uniformly.
When baking these sweet potatoes, make sure that none of them are overlapping. This lets the steam escape and results in a light crisp outer layer on the roasted sweet potatoes.
