Ingredients
For 2–3 servings:

2 medium sweet potatoes (about 1 lb / 450g total)
-
1 tablespoon olive oil (or avocado oil for higher heat)
-
1 teaspoon cornstarch (secret to extra crispiness!)
-
½ teaspoon garlic powder
-
½ teaspoon smoked paprika
-
¼ teaspoon black pepper
-
½ teaspoon sea salt, divided
-
Optional: ¼ teaspoon chili powder or cinnamon for extra flavor
For Serving (optional):

Choosing the Right Sweet Potatoes
Not all sweet potatoes crisp up the same. To achieve the best results:
-
Go for firm, dry sweet potatoes — moisture leads to sogginess.
-
Avoid overly large potatoes, which can be harder to cut evenly.
-
Orange-fleshed varieties caramelize best in the air fryer.
How to Cut Perfect Fries
-
Peel the sweet potatoes (optional — the skin adds texture and nutrients if you prefer).
-
Cut off the ends.
-
Slice lengthwise into ½-inch thick planks, then cut each plank into even strips.
-
Aim for uniform thickness to ensure even cooking.
Pro tip: If you want ultra-thin “shoestring” fries, reduce the cooking time slightly to prevent burning.
Step-by-Step Instructions
Step 1: Soak the Fries
Place cut fries in a large bowl of cold water and soak for 20–30 minutes. This step removes excess starch, helping the fries crisp instead of steam.
Drain and pat them completely dry with paper towels. Moisture is the enemy of crispiness, so don’t skip this step!
Step 2: Season the Fries
In a clean mixing bowl, toss the dried fries with:
-
Olive oil
-
Cornstarch
-
Garlic powder
-
Smoked paprika
-
Salt and pepper
Toss until every fry is lightly coated. The cornstarch creates a thin, crisp outer layer, mimicking the texture of fried fries.
Step 3: Preheat the Air Fryer
Set your air fryer to 380°F (193°C) and preheat for 3–5 minutes. A preheated basket ensures the fries start crisping the moment they go in.
Step 4: Arrange and Air Fry
-
Arrange fries in a single layer in the air fryer basket. Do not overcrowd — cook in batches if needed.
-
Air fry for 12–15 minutes, shaking the basket halfway through.
-
Check after 10 minutes — every air fryer cooks slightly differently.
When done, fries should be golden-brown and crisp at the edges with soft, fluffy centers.
Step 5: Season and Serve
Immediately sprinkle with a pinch of salt while they’re hot — this helps seasoning stick. Serve right away for the crispiest texture.
Pair with your favorite dipping sauces, like:
-
Garlic aioli (mix mayo, lemon juice, and garlic)
-
Honey mustard (combine Dijon, honey, and a touch of vinegar)
-
Spicy yogurt dip (Greek yogurt, paprika, and lime juice)
Tips for the Crispiest Air Fryer Sweet Potato Fries
1. Don’t skip soaking.
It’s the single most effective way to remove starch and get fries that actually crisp.
2. Use cornstarch wisely.
Too much can make fries chalky; just a teaspoon per batch is perfect.
3. Avoid overcrowding.
Air needs to circulate freely for even cooking. Do multiple batches if necessary.
4. Shake midway.
This helps every fry cook evenly and prevents sticking.
5. Serve immediately.
Air fryer fries lose crispness as they sit. If you’re cooking in batches, keep finished fries warm in a 200°F (90°C) oven.
Flavor Variations
You can easily customize your fries to match any craving or occasion:
Classic Savory: Garlic powder + paprika + black pepper.
Spicy Kick: Add cayenne, chili powder, or hot smoked paprika.
Sweet & Spicy: Cinnamon + paprika + pinch of brown sugar.
Herb Infusion: Dried rosemary or thyme for an earthy twist.
Zesty Lemon Pepper: Add lemon zest and cracked black pepper before serving.
Serving Ideas
-
As a side dish: Pair with grilled chicken, burgers, or veggie wraps.
-
As a snack: Enjoy with hummus or guacamole.
-
For brunch: Top with a fried egg and herbs.
-
For kids: Serve with ketchup or honey mustard.
These fries are the perfect balance of comfort food and smart eating — light, crisp, and satisfying.
Nutritional Benefits
Sweet potatoes aren’t just delicious — they’re nutrient powerhouses:
-
Rich in fiber to support digestion.
-
Packed with beta-carotene for healthy eyes and immune function.
-
Loaded with vitamins A, C, and potassium.
-
Naturally sweet without refined sugar.
When air-fried, they maintain their nutrients without being drenched in oil — making them one of the healthiest “fries” you can enjoy guilt-free.
Troubleshooting: Common Issues
My fries came out soggy:
You may have skipped soaking or overcrowded the basket. Cook in smaller batches and dry thoroughly before seasoning.
They’re too dark but not crisp:
Reduce temperature slightly and increase cooking time by 2–3 minutes.
Fries stuck to the basket:
Use a light spray of oil before cooking, or line with parchment paper designed for air fryers.
Uneven browning:
Shake or toss halfway through the cooking process.
How to Store and Reheat
To Store:
Cool fries completely and store in an airtight container for up to 3 days in the refrigerator.
To Reheat:
-
Air fryer: 350°F (175°C) for 3–5 minutes until re-crisped.
-
Oven: 400°F (200°C) for 6–8 minutes.
-
Avoid microwaving: It makes fries soggy.
Make-Ahead Tips
If you want to prep ahead:
-
Cut and soak fries: Up to 24 hours in advance, kept submerged in cold water in the fridge.
-
Season just before cooking: Keeps fries from absorbing too much moisture.
-
Batch cooking: Double the recipe and freeze extras (see below).
How to Freeze Air Fryer Sweet Potato Fries
-
Arrange cooled fries on a baking sheet in a single layer.
-
Freeze for 1 hour until solid.
-
Transfer to a freezer-safe bag and store for up to 2 months.
-
Reheat directly from frozen — no need to thaw — at 380°F (193°C) for 10–12 minutes.
Dipping Sauce Ideas
Because fries are only as good as their dips, here are some delicious options to try:
Garlic Herb Aioli: Mayo + minced garlic + lemon juice + parsley.
Sweet Chili Sauce: A simple Asian-inspired pairing.
Smoky Ketchup: Mix regular ketchup with a dash of paprika and hot sauce.
Honey Mustard Yogurt Dip: Greek yogurt + honey + Dijon mustard.
Avocado Lime Dip: Mashed avocado + lime juice + pinch of salt.
Frequently Asked Questions
Can I make these fries completely oil-free?
Yes. The fries will still cook and crisp, though slightly less golden. Use a light spritz of water or oil spray for the best texture.
Do I need to peel the sweet potatoes?
No — the skin becomes nicely crisp and adds fiber. Just scrub them clean.
Can I make them in the oven instead?
Yes! Bake at 425°F (220°C) for 25–30 minutes, flipping halfway through.
Why use cornstarch?
It absorbs surface moisture and mimics the crunch of deep-fried coating.
How do I prevent them from burning?
Watch during the last few minutes — sweet potatoes have natural sugars that caramelize quickly.
Expert Tips for Extra Crispiness
-
Use a mesh-style air fryer basket — it circulates air better than solid trays.
-
Allow fries to cool slightly before serving — this helps them firm up.
-
Sprinkle seasoning after cooking if using salt-heavy blends to avoid drawing out moisture early.
-
Mix and match shapes — try crinkle cuts or wedges for variety!
