Oven Sweet Potato Fries with Tapioca Flour

An easy way to make Oven Sweet Potato Fries with Tapioca Flour instead of Cornstarch. The perfect substitution if you are allergic to corn.

This recipe will leave you with a salty-sweet and free guilt craving. The potato fries are a bit crunchy, sweet, salty, and with a hint of savory herbs from Noubess Garlic and Herb Seasoning.  

Why keep frying potatoes and have tons of cleaning to do in the kitchen when you can make a stress-free oven-baked sweet potato fries recipe. Over the years, I have learned to make life simpler by incorporating healthier ingredients in my cooking. With food allergies on the rise, it is better to look for alternatives than waiting until you have symptoms you cannot control.

What is Tapioca Flour and why use it instead of Cornstarch.

As a versatile gluten-free flour, Tapioca flour is a great flour for baking and cooking. It is made from the starch of the cassava root and used as a thickening agent, and as the main ingredient in several recipes. 

Tapioca flour is a great substitute for cornstarch and for people with corn allergies. When using tapioca flour as a substitution, and depending on the recipe, the amount of flour needed will differ. For instance, you may need more tapioca flour to thicken a stew or sauce – 1 tbsp of cornstarch to 2 tbsp tapioca flour. For coating sweet potatoes use less tapioca flour for the fries to be crispy. 

The sweet potatoes fries won’t be totally crispy but you will have some crispiness at least. Don’t expect the same texture as if the fries were fried in oil.

Should you soak in cold water or not soak? 

I will say soak to remove some of the starch, to keep the potato pieces looking fresh and not brownish or with dark ends. And do not soak if you only have 2 sweet potatoes for this particular recipe.

Let say you have about 6 potatoes to peel, by the time you get to the 3rd one, the first peeled potato would already have a couple of brown spots. Same as regular white potatoes. So soaking makes sense! Unless you are cooking for one then you are good to go. 

But again soaking helps release some of the starch and may also help keep the potatoes moist inside. 

Is soaking required? It all depends on your preference.

Unfortunately, this recipe is not child-friendly because you need to use a sharp knife

  1. Peel the potatoes one by one. Slice thinly, about 1/4“ wide – don’t worry if they are not the exact size. 
  2. If you have more than 3 potatoes, I would recommend soaking the potatoes while you are done slicing them. 
  3. If you soak the potatoes, make sure you dry them carefully before coating or seasoning.
  4. Add the seasoning and gently coat the potatoes. 
  5. Add the tapioca flour and gently coat the potatoes. 
  6. Place the potatoes on the prepared baking pan(s), do not pile them up. Make sure you leave enough room between the potatoes. 
  7. Bake at 425 degrees Fahrenheit 25-30 minutes. Halfway through cooking time, remove the pan(s) from the oven and flip the fries. 

Tips and Notes:

  • Do not crowd the pan as the potatoes fries will become soggy.
  • Serving size is usually one potato per person. 
  • Set your oven temperature to 400 or 425 degrees Fahrenheit or the fries won’t crisp. 
  • Rotate the pan(s) to ensure even cooking and to avoid the tips from burning.
  • Use a vegetable peeler to remove the skin and a sharp knife to slice the potatoes
  • Wash the potatoes before peeling or slicing. 
  • Use parchment paper or silicone baking mat to line the sheet pans.
  • Use a bowl or ziplock bag to toss the potatoes
  • Don’t add too much oil.
  • The fries will be crispier if you use cornstarch instead of tapioca flour. But if you are allergic to corn, tapioca flour might be the best option for you to enjoy Oven Potato Fries.
