The SECRET to Crispy Baked Sweet Potato Fries | Say Goodbye to Limp & Soggy Fries

These Crispy Baked Sweet Potato Fries are seriously addictive. They have an incredible light crispy texture on the outside and a melt-in-your-mouth interior. Serve them as a tapas appetizer or even as a side dish, next to some grilled fish or an eggplant burger.

I love to serve these Crispy Baked Sweet Potato Fries next to a saffron mayo aioli. As it takes these fries to the next-level. You can easily veganize the dip by using vegan mayonnaise instead of regular mayonnaise. Either way, this dip is a MUST with these sweet potato fries.

I kept the skins on the sweet potatoes, just to keep more nutrients, but you can peel the sweet potatoes if you like. The most important part is to make sure you cut all your fries in the similar size. About 1/4 inch (.635 cm) sized cut fries, that way they all evenly cook.

TIPS & TRICKS to Make this Recipe: The main secrets to achieving that incredible crispy texture, is to soak the cut sweet potatoes in cold water for at least 30 minutes. This helps remove the starch from the sweet potatoes so they´re not limp & soggy. The other secret is the corn starch. As it helps in achieving that light crispy texture.

    The Secret to Burned Soggy Sweet Potato Fries. Wish I could attach a video showing I followed the steps perfectly, using a new oven that is otherwise producing excellent results. So why can something like this go so wrong? I always see comments like this on other foods blogs, but things always turn out ok for me. But finally I am the one who failed! Any ideas? I guess try lower temperature? Thicker cut fries?

    Who has an oven that you can turn bake and broil on at the same time? Not mainstream USA. No matter I will try it on bake and crisp with low broil and see how they turn out.
