Why I Love Air Fryer Sweet Potato Fries
I’ve always had a soft spot for sweet potatoes. Their natural sweetness and all those good-for-you nutrients make them a staple in my kitchen. I already have a go-to sweet potato fries recipe on my site that I make all the time, but I wanted something that felt a little more cozy for fall.
Instead of my usual savory spice blend, I went with a mix of cinnamon and sugar. It gives the fries that warm, sweet flavor that feels just right on a cool evening. The result is golden edges, soft centers, and a light dusting of cinnamon-sugar that makes each bite taste like comfort.
You can toss them straight into your air fryer, give them a shake halfway through, and about 20 minutes later you’ll have a batch of perfectly crisp, golden fries ready to serve. It’s a fabulous snack that’s simple, quick, and absolutely delicious.
The Secret to Crispy, Cinnamon Sugar Sweet Potato Fries
If you’ve ever pulled soft, soggy fries out of your air fryer, you’re definitely not alone. Getting that perfect crispy texture just comes down to a few small steps.
1. Preheat the air fryer
I used to skip this step, but starting with a hot basket helps the fries crisp up right away instead of steaming.
2. Add a little starch
Toss the fries with a small amount of arrowroot starch or cornstarch before adding oil. It creates a thin coating that makes a huge difference in the crunch. The arrowroot starch is a solid workaround if you don’t have time to soak the fries.
3. Soak if you can
If you have a few extra minutes, soak the cut fries in cold water for 20 to 30 minutes. This removes some of the excess starch, which means extra crispy fries later. Drain them well and pat completely dry. I usually spread them out on a kitchen towel to get rid of every bit of moisture. I’ll be honest, I don’t always take the time to soak them, but when I do, the results are worth it.
4. Don’t crowd the basket
Give the fries some breathing room so the air can circulate around each one. That’s the secret to those golden, crisp edges that make these fries so addictive.
Ingredients You’ll Need:
Here’s what goes into my Air Fryer Cinnamon Sugar Sweet Potato Fries:
4 medium sweet potatoes (about 3 lbs total), peeled and cut into fries
3 tablespoons avocado oil
2 teaspoons arrowroot starch or cornstarch (optional, helps make them crispier)
3 tablespoons coconut or brown sugar
2 teaspoons cinnamon
Pinch of sea salt before cooking + more for sprinkling after

How to Cut Sweet Potatoes
Cutting sweet potatoes can be tricky because they’re so firm. Here’s my go-to method:
Rinse the sweet potato under cool water and peel with a vegetable peeler to remove the skin.
Slice off both pointed ends so you have flat surfaces, this makes the potato more stable and safer to cut.
Stand the sweet potato upright on one of the flat ends. Slice straight down to make ¼-inch thick planks (like long flat sheets).
Stack a few planks at a time and slice them again lengthwise into even ¼-inch sticks.
Try to keep all the fries about the same thickness so they cook evenly in the air fryer.

Instructions
1. Preheat the air fryer to 380°F.
2. Peel & cut sweet potatoes: Slice off both ends, stand upright, and cut into ¼-inch planks. Stack and slice into even matchsticks or wedges.
3. Add fries to a large bowl. Sprinkle arrowroot starch or cornstarch (if using) and toss to coat evenly. Then drizzle in avocado oil and toss again.
4. Arrange fries in a single layer, add a sprinkle of salt on top. Cook for 18–20 minutes, shaking halfway through. Fries should be golden and crisp around the edges. Work in batches if needed.
5. Mix sugar and cinnamon in a small bowl. Once fries are done, let them rest for 2 minutes (this helps the sugar stick without melting off), then toss with the cinnamon-sugar mixture.
6. Sprinkle it with a bit more salt before serving.
Recipe Notes
Air fryer times can vary slightly depending on your model. Start checking your fries around the 15-minute mark.
Toss or shake the basket halfway through cooking for even browning.
Cook the fries in a single layer, meaning they shouldn’t overlap in the basket. If they do, they’ll steam instead of crisp, so cook in batches if needed.
How to Serve & Store
These Cinnamon Sugar Sweet Potato Fries are best served warm, fresh out of the air fryer when they’re perfectly crispy and coated in that sweet cinnamon-sugar goodness. They make such a fun side for brunch, a cozy afternoon snack, or even a light dessert after a savory meal.
I love pairing them with something cool and creamy, like a simple honey yogurt dip or a touch of vanilla Greek yogurt. The contrast between warm, spiced fries and the chill of the dip is so satisfying.
If you have leftovers, store them in an airtight container in the fridge for up to 3 or 4 days. When you’re ready to enjoy them again, pop them back into the air fryer at 375°F for about 3 to 5 minutes. They crisp right back up and taste just as good as the first time.
