I started making sweet potato fries a few years ago. We really love them, but they always ended up being soggy. I happened to see somewhere that the fries cannot be touching while cooking or they will end up soggy. Bingo! Now, we separate them and no more soggy fries!
First things first. I cut up one large sweet potato into fries. I then toss the fries in a bowl with olive oil, salt and pepper. Next, I place them on the baking sheet with room to breathe! Bake at 450 degrees for about 10 minutes, flip and then bake for 10 minutes more. You can cook them longer if you want them extra crispy :-) They do get darker as you bake them, but it is carmelization, not burnt-ness! Try them, you might like them!
