Pour cubed sweet potatoes into a medium mixing bowl and add olive oil, salt, and pepper, Toss gently with hands ensuring that all potatoes have oil on them.
Pour potatoes onto a sheet pan and make sure they are laid out into a single layer for even cooking. Bake for 20-25 minutes. Give them a quick stir about halfway through.
Add additional seasoning if desired.
Notes
I used the precut sweet potatoes and I got some yummy small bits with those.
