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.
Finally, I realized I had to create my own recipe. It occurred to me in one of my experiments that the real crispiness was happening when the fries were in contact with the hot baking sheet. I realized that I could get better browning if I started with a hot pan and if I turned them at least once, maybe twice, so they could get contact with that pan on multiple edges. I also extended the time they spend in the oven well beyond any other published recipes I’ve seen.
Be warned… these are about a nanometer away from being burnt, but that is the way I wanted them. When you get to the last 5-10 minutes of baking, you really need to watch them closely. Keep in mind that oven temperatures will vary and the natural variances in sugar content in the sweet potatoes likely plays a role in variations. I’ve been able to reach this perfect crispiness in as few as 30 minutes and other times it has been as much as 45. Patience is the key here!
A note about fat
I think these are best with lard, but I don’t recommend using grocery store lard. If possible, render your own from fat you get from a farmer you trust. If you must purchase lard, be picky and look for pasture raised pork. Good sources are Fat Works and Tendergrass Farms, both of which are currently available through Amazon as well as direct.
If you can’t get lard, or if you don’t eat pork, you can use another rendered animal fat or coconut oil.
Notes for healing diets
- Paleo Autoimmune Protocol (AIP)/The Paleo Approach (TPA) – As long as you use a healthy fat like pastured lard or coconut oil, this is compliant.
- Specific Carbohydrate Diet (SCD) – Not legal.
- Low-FODMAP – Sweet potatoes are high in polyols, but Monash University says that as long as you keep the serving under 1/2 cup, they will not bother most people.
