Preheat oven to 425°F. Peel and dice sweet potatoes.
2 pounds sweet potatoes
Add diced sweet potatoes to a sheet pan. Add oil and seasonings and toss to combine. Spread into an even layer so that they're not touching or overlapping on the tray.
Place tray in the oven and roast 25-30 minutes. You can use a spatula to toss them every 10 minutes for more even browning, if you'd like. Sweet potatoes are going to be browned and crisped on the edges and fork-tender when done. (Note that the larger you dice or cube your sweet potatoes, the longer time it will take!)
