What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples, so you won’t need to make a special trip to the store.

• Sweet potatoes: 2 medium-sized, peeled and cut into 1/4-inch thick fries (I prefer the orange variety for sweetness and color)
• Cornstarch: 2 tablespoons (this is the secret to that crispy outside)
• Olive oil: 1-2 tablespoons, for light coating (use extra virgin for best flavor)
• Sea salt: 1 teaspoon, adjust to taste
• Smoked paprika: 1/2 teaspoon (adds a subtle smoky kick)
• Garlic powder: 1/2 teaspoon (for a little savory depth)
• Black pepper: Freshly ground, about 1/4 teaspoon
• Optional: A pinch of cayenne pepper for some heat (perfect if you like a spicy touch)

Ingredient tips: If you want a gluten-free option, cornstarch works perfectly here. For a dairy-free or vegan recipe, this one’s naturally good to go. If you can’t find smoked paprika, regular paprika will do, but don’t skip it—it really makes a difference. When choosing sweet potatoes, look for firm ones without soft spots or wrinkles for the best texture.

Equipment Needed

• Air fryer: Obviously the star here; any model with a basket works well. I use a 5.8-quart air fryer, which is perfect for this quantity.
• Sharp knife: For slicing the sweet potatoes evenly—this helps them cook uniformly.
• Mixing bowl: To toss the fries with cornstarch and seasoning.
• Tongs or spatula: For shaking the basket and flipping fries halfway through cooking.
• Measuring spoons: To get the seasoning just right.

If you don’t have an air fryer, a convection oven with a baking tray and wire rack can work, but expect a longer cooking time and less crispiness. For budget-friendly options, smaller air fryers are great for singles or couples, just reduce the batch size accordingly. Keep your air fryer basket clean and dry between batches to avoid soggy fries.

Preparation Method

1. Prep the sweet potatoes: Peel and cut 2 medium sweet potatoes into 1/4-inch thick fries. Try to keep them as uniform as possible for even cooking (about 1/4 inch by 1/4 inch thickness and 3-4 inches long). This takes about 10 minutes.
2. Dry the fries: Pat the cut fries dry with a clean kitchen towel or paper towels to remove excess moisture. This is key to getting them crisp. Spend 2-3 minutes here.
3. Toss with cornstarch: Place the fries in a large mixing bowl. Sprinkle 2 tablespoons of cornstarch evenly over the fries. Toss well until all fries have a light coating. You’ll notice a powdery, almost matte finish—that’s perfect.
4. Add oil and seasoning: Drizzle 1-2 tablespoons of olive oil over the fries. Sprinkle with 1 teaspoon sea salt, 1/2 teaspoon smoked paprika, 1/2 teaspoon garlic powder, 1/4 teaspoon freshly ground black pepper, and a pinch of cayenne if using. Toss again to coat evenly. This step takes about 2 minutes.
5. Preheat the air fryer: Preheat your air fryer to 400°F (200°C) for 3-5 minutes. Preheating helps start the crisping process right away.
6. Arrange fries in the basket: Place the fries in a single layer in the air fryer basket. Avoid overcrowding to ensure even cooking. You might need to cook in batches depending on your air fryer size.
7. Cook the fries: Air fry at 400°F (200°C) for 15-20 minutes. Shake the basket or use tongs to flip the fries every 5 minutes for even crisping. Keep an eye on them after 15 minutes since air fryer models vary.
8. Check for doneness: Fries should be golden brown and crispy on the outside but tender inside. If they need more crisping, cook in 2-minute increments. Total cook time depends on thickness and air fryer model.
9. Serve immediately: Transfer fries to a plate lined with paper towels to soak up any excess oil. Serve hot for the best crunch.

Pro tip: If the fries seem too soft or soggy, next time try slicing a bit thinner and drying them longer before cooking. Also, don’t skip the cornstarch—it’s a game changer in crispness. For bigger batches, work in smaller batches to maintain airflow.

Cooking Tips & Techniques

Getting perfectly crispy air fryer sweet potato fries can be tricky at first, but a few tricks have saved me from soggy fries more times than I can count. Let me share what I’ve learned.

• Pat dry like a pro: Moisture is the enemy of crispiness. After cutting, drying your fries thoroughly is a must. I usually pat twice with fresh towels.
• Use cornstarch: This little powder coats the fries and crisps up beautifully in the air fryer without making them gummy.
• Don’t overcrowd: Air needs to circulate around each fry to get that crunch. Cook in batches if needed—trust me, it’s worth the extra effort.
• Shake it up: Toss or flip the fries halfway through cooking for even color and texture. I set a timer every 5 minutes to remember.
• Season at the right time: Toss fries with oil and seasoning before cooking rather than after; this helps flavors stick and fries crisp up.
• Adjust timing: Depending on your air fryer size and the thickness of your fries, the cooking time might vary. Start checking at 15 minutes and add a couple more minutes if needed.

Honestly, I’ve burned a batch or two by leaving them unattended (we all have!). Multitasking helps, but keeping your eyes on the clock is key. These tips have made all the difference in turning out fries that are crispy on the outside, tender on the inside, and downright addictive.

Variations & Adaptations

This recipe is super flexible, so you can tweak it to fit your mood or dietary needs.

• Spicy Cajun Fries: Swap smoked paprika and garlic powder for Cajun seasoning. Add a dash of cayenne for a fiery kick I personally love.
• Herb & Parmesan: After cooking, toss fries with finely grated Parmesan and chopped fresh rosemary or thyme for a savory twist.
• Sweet & Cinnamon: For a sweeter snack, sprinkle fries with cinnamon and a touch of brown sugar right after cooking. Great for dessert or breakfast sides.
• Gluten-Free & Paleo: This recipe is naturally gluten-free. Use avocado oil instead of olive oil for a paleo-friendly fat option.
• Baked instead of Air Fried: If you don’t have an air fryer, bake in a 425°F (220°C) oven on a wire rack for 25-30 minutes, flipping halfway, until crisp.

I once tried tossing these fries in a chipotle-lime sauce after cooking—dangerously good! Feel free to experiment and make this recipe your own.

Serving & Storage Suggestions

These crispy air fryer sweet potato fries are at their best fresh out of the fryer—hot and crunchy. Serve them immediately with your favorite dipping sauces like garlic aioli, spicy ketchup, or even a creamy avocado dip.

Pair them alongside burgers, grilled chicken, or a fresh salad for a well-rounded meal. They also shine at parties or as a snack with a cold drink.

To store, let fries cool completely, then place in an airtight container lined with paper towels. Refrigerate for up to 3 days. Reheat in the air fryer at 350°F (175°C) for 3-5 minutes to restore crispiness. Avoid microwave reheating if you want to keep that crunch.

Flavors tend to mellow overnight, making them a great make-ahead snack. Just reheat right before serving for best texture.
