Sweet potato fries, made in the oven at home, that are actually crispy? YES! It is possible! I have tried so many different versions of this recipe since adopting a paleo diet and been disappointed with every single one. Sure, they tasted fine, but they were limp and soggy, never crispy. Some recipes called for pre-cooking, others directed a soak in salted water. Some used just a little fat, others practically drowned the taters in grease. But no matter the variation, they never got to that crispy, bordering on nearly burnt, doneness that would stand up to a thick mayonnaise dip.
