Sweet potato recipes tend to be more popular in the fall, around the holiday season - although you can make them year round.

What makes this recipe so yummy
- Of course, the fact that sweet potatoes are a little healthier than their white cousins.
- Sweet potatoes can be seasoned in a number of ways. You could sweeten them, or add some slight spice like I did in this recipe.
- These crispy roasted sweet potatoes make the perfect side dish for any meal.

Recipe walkthrough: Instructions
This is an overview of the recipe steps. For more detailed instructions visit the recipe card at the bottom of this post.
Using a sharp kitchen knife, cut sweet potatoes into even sticks, about ¼ inch each.
Bake fries for 10-12 minutes rotate the pan position and flip the fries and continue baking for another 10-12 minutes.
Fries are done when the outside turns from a shiny wet orange color to a more matte orange.
Step 6: Remove from oven and sprinkle with spice mix, toss to coat fries in seasoning.
Hint: It's extra important to space the sweet potato fries out enough for good air to circulate. If they're too close together they will cook in their own steam and will not become as crispy.
Recipe variations and substitute ideas
- Regular Potatoes - you can use this same recipe and sub out the sweet potatoes for regular white potatoes.
- Chili Powder - use this instead of the cayenne for a little spice.
- Sweet Potato Chunks - cut the potatoes into chunks instead of fries.
- Avocado Oil - use this instead of olive oil (or any oil for that matter, as long as it has a high smoking point).
- Fresh Garlic - instead of garlic powder.
- Fresh Thyme - sprinkle some fresh thyme.
- Seasoning Mixture - this is very flexible. You could make the fries more sweet than spicy (add a little brown sugar). It's all up to you.

How to store leftovers
These crispy sweet potato fries can be stored in an airtight container, lined with paper towel, in the refrigerator for about 3 days.
Mel's kitchen notes
To reheat these fries I recommend doing so in the oven again, to crisp them up. Even better - in the air fryer if you have one.

Frequently asked questions: FAQs
Can I make this ahead of time and freeze it?
I would not recommend freezing these.
You can peel and cut the sweet potatoes two days in advance. Just keep them in a bowl of water to prevent browning.
Why are my sweet potato fries soggy?
It is important not to overcrowd the pan when baking. If your pan is too crowded the sweet potato fries will steam and will not become crispy.
