I was definitely thinking of this Pioneer Woman recipe (here) when I made them. I didn't go too in depth, though. I sliced my sweet potato, tossed the pieces in olive oil, laid them on the pan (lined with foil so I wouldn't have to wash it later), and sprinkled on rosemary and brown sugar. I baked them at 400 for 20 minutes.
I hope to come up with several ways to serve (and eat) sweet potato fries this summer - an easy and healthy snack!
