I bought a bunch of sweet potatoes the week of Thanksgiving, because they were only $0.25/lb. I've been meaning to make a bunch of sweet potato chips, but instead, we used a couple to make sweet potato fries.
All you need to do is preheat your oven to 450 degrees. Peel the potatoes and cut them in half:
Then cut into 3/4 inch chunks and toss into a plastic bag to season:
Then add about 1/4 c. olive oil, sea salt and pepper. Zip bag shut, and toss around:
Then lay them on cookie sheet and make sure they aren't touching. If they do touch, it will make them mushy.
Then place them in the oven for 15 minutes, and when the timer beeps, turn them over. Place them in the oven for another 10 minutes.
