- Homemade Cajun seasoning. Keep a batch of this simple homemade spice mix on hand and add it to everything! It takes these sweet potato fries over the top without making them too spicy. You can also use store-bought Cajun seasoning but may need to adjust the amount. If you're sensitive to spice, reduce or omit the cayenne.
- Granulated sugar. This ingredient is totally optional but a small amount really brings out the sweetness of the potatoes.

Step 1. Scrub the sweet potatoes clean and slice them into ¼-inch matchsticks. Transfer them to a bowl and add the melted coconut oil and Cajun seasoning. Toss the fries to coat evenly.
Step 2. Divide the fries among two baking sheets and arrange them in a single layer. Bake the fries for 15 minutes at 425°F, carefully flip or toss them, then bake another 10 to 15 minutes until crispy.
Variations

Tips For the Best Oven Baked Fries
- Slice the potatoes as evenly as possible to avoid soggy or burnt fries.
- Want extra crispy fries? Try tossing the fries in 2 tablespoons of cornstarch before adding the oil and seasoning.
- Do not overcrowd your pan to avoid soggy fries. Divide the fries among two baking sheets so the fries have plenty of room to crisp up.
What Is the Best Way to Slice Sweet Potato Fries?
The easiest way to hand-cut sweet potato fries is to cut the ends off the potato and rest it on its side on a sturdy cutting board. Slice the potato into ¼ inch slabs lengthwise, then slice each slab into matchsticks. As you're working, you will need to turn the potato to the flattest side to maintain stability.
Make-Ahead and Storing Instructions
If you want to slice your potatoes a day or two in advance, store them by covering them with cold water in an airtight container. Pat the potatoes dry before proceeding with the recipe.
Leftover sweet potato fries can be stored in an airtight container in the refrigerator for up to five days. Reheat the fries in the oven for the crispiest texture or reheat them in the microwave.
