Ingredients You’ll Need
Olive oil: Just 1 tablespoon is all you need to get these fries perfectly crispy. The oil helps all those wonderful spices stick to every single fry.
Sea salt: A quarter teaspoon brings out the natural sweetness of the potatoes. Regular table salt works great too if that’s what you have!
Ground black pepper: This adds a nice little kick with just 1/4 teaspoon. Freshly ground pepper tastes even better if you have it.
Cayenne pepper: A quarter teaspoon gives these fries a gentle heat that’s not too spicy. You can use less if you’re making these for little ones.
Ground cinnamon: This is the secret ingredient that makes these fries special! Just 1/4 teaspoon adds warmth and pairs beautifully with sweet potatoes.
Sweet potatoes: You’ll need 2 medium sweet potatoes, peeled and cut into 1/4-inch sticks. Look for potatoes that feel firm and have smooth skin for the best results.
How to Make Air-Fryer Sweet Potato Fries

Step 1: Lightly spray your air-fryer basket with cooking spray so nothing sticks. This little step makes cleanup so much easier later!
Step 2: Grab a large bowl and mix together the olive oil, salt, pepper, cayenne, and cinnamon. Give it a good stir so all the spices are well combined.
Step 3: Add your sweet potato sticks to the bowl with the spice mixture. Toss everything together with your hands or a spoon until every fry is nicely coated.
Step 4: Place the seasoned sweet potatoes in a single layer in your prepared air-fryer basket. Don’t overcrowd them or they won’t get crispy!
Step 5: Cook at 400 degrees F for about 14 minutes, flipping the fries halfway through cooking. They’re done when they look golden brown and crispy on the outside.
Step 6: Transfer your beautiful fries to a plate lined with paper towels. This absorbs any extra oil and keeps them crispy while you serve them up hot!
Easy and Quick Air-Fryer Sweet Potato Fries Version
Want to make this even simpler? You can totally skip peeling the sweet potatoes if you scrub them really well first! The skin adds extra nutrition and saves you prep time. Just cut them into fries, toss with 1 tablespoon oil and 1/2 teaspoon of your favorite seasoning blend, then air fry the same way.
Serving Ideas
These crispy fries make a perfect side dish for burgers, grilled chicken, or fish. They’re also amazing as a healthy snack with a dollop of Greek yogurt or your favorite dipping sauce. Try them with creamy ranch, spicy mayo, or even a drizzle of honey for something sweet!
Storage
Store leftover fries in the refrigerator for up to 3 days in a covered container. To reheat them and get that crispiness back, pop them in your air fryer at 350°F for 2-3 minutes. You can also reheat them in a regular oven at 400°F for about 5 minutes.
Substitutions
No cayenne pepper? No worries! Try paprika, garlic powder, or even a pinch of chili powder instead. If the cinnamon-pepper combo sounds too adventurous, swap it out for thyme, oregano, or rosemary. Regular potatoes work great too if sweet potatoes aren’t your thing!
Pro Tips
- Cut evenly: Make sure all your fries are about the same thickness so they cook at the same rate.
- Don’t skip the flip: Flipping halfway through gives you crispy fries on all sides.
- Single layer is key: Cook in batches if needed rather than crowding the basket.
- Serve immediately: These taste best right out of the air fryer while they’re still hot and crispy.
FAQs
Can I make these without an air fryer?
You bet! Spread the seasoned fries on a baking sheet and bake at 425°F for 20-25 minutes, flipping once halfway through. They’ll still turn out deliciously crispy in your regular oven.
How do I know when the fries are done?
Look for golden brown edges and a crispy texture when you gently shake the basket. They should feel firm when you poke them with a fork, not soft or mushy.
Can I prep these ahead of time?
Sure! You can cut the sweet potatoes and store them in water in the fridge for up to 24 hours. Just pat them dry really well before seasoning and cooking.
