Oven Baked Spicy Sweet Potato Fries

Learning how to make sweet potato fries is a must, especially when you live in Idaho (AKA the "Famous Potatoes" state) like we do.  If you don't know how to do this, it's time to learn.  You can thank me later. Whether you use sweet potatoes or yams, you'll love this recipe.  I prefer yams due to their bright orange color.  They're just beautiful.

How to Make Sweet Potato Fries: The Secret to the Art of Crispiness 

How do you get a crispy, non-mushy sweet potato fry in the oven?  You need to use oil.  Period.  The great part about baking the fries instead of deep frying them is that the amount of oil used is greatly reduced.  By just tossing your cut yams in a few tablespoons of oil, you will get a delightfully crunchy fry with less calories.  The oil also helps seasoning stick to the fries.

I use coconut oil because I love the sweet, nutty flavor the coconut oil imparts to these fries. However, you can use olive oil, vegetable oil, avocado oil, etc.

Season before or after cooking?

I always toss my raw fries in oil, sprinkle seasoning, and toss again.  This is great for 2 reasons: 

  1. The oil helps the seasoning stick to the fries
  2. The seasoning toasts during cooking, increasing flavor and decreasing bitterness.

The first reason is kind of a no-brainer.  The second reason may be less intuitive.  Spices, especially chiles and related peppers, need to have a little heat on them to toast them to reduce bitterness and bring out their depth of flavor.

We used our Three Kings Smoky Spicy & Seasoning Blend, but you can use your favorite seasoning salt if you'd like.
