Air Fried Sweet Potato Fries (Printable)

Crispy sweet potato fries made in the air fryer with a creamy garlic aioli dip.

# What You’ll Need:

→ Sweet Potato Fries

01 - 2 large sweet potatoes, peeled and cut into 1/4-inch thick fries
02 - 2 tablespoons olive oil
03 - 1 teaspoon smoked paprika
04 - 1/2 teaspoon garlic powder
05 - 1/2 teaspoon fine sea salt
06 - 1/4 teaspoon black pepper
07 - 1 tablespoon cornstarch, optional for extra crispiness

→ Garlic Aioli

08 - 1/2 cup mayonnaise
09 - 1 clove garlic, finely minced
10 - 1 teaspoon lemon juice
11 - 1/2 teaspoon Dijon mustard
12 - Salt and black pepper to taste

# How To Make It:

01 - Peel the sweet potatoes and cut them into 1/4-inch thick fries.
02 - Place the fries in a bowl of cold water and soak for 20 minutes to remove excess starch. Drain thoroughly and pat completely dry with a kitchen towel.
03 - Toss the fries with olive oil, smoked paprika, garlic powder, salt, pepper, and cornstarch if using until evenly coated.
04 - Preheat your air fryer to 400°F for 3 minutes.
05 - Arrange the fries in a single layer in the air fryer basket, cooking in batches if necessary.
06 - Air fry for 15-20 minutes, shaking the basket halfway through, until fries are golden and crisp.
07 - While the fries cook, mix mayonnaise, minced garlic, lemon juice, Dijon mustard, salt, and pepper in a small bowl. Adjust seasoning to taste.
08 - Serve the hot sweet potato fries immediately with garlic aioli on the side.

# Expert Advice:

01 -
  • They're genuinely crispy outside and creamy inside, without the guilt of deep-fried versions.
  • The garlic aioli is so simple you'll wonder why you ever bought expensive dipping sauces.
  • Fifteen minutes of active prep means you can have restaurant-quality snacks faster than delivery arrives.
02 -
  • Skipping the soak step will leave you with soft fries that taste like baked potatoes—I learned this the hard way and never skip now.
  • Crowding the air fryer basket is the second biggest mistake; it steams the fries instead of crisping them, and I once made this error with guests arriving in thirty minutes.
  • The cornstarch addition sounds strange but creates a texture almost identical to deep-fried fries without any of the oil.
03 -
  • If you want spicier fries, a pinch of cayenne or a dash of hot sauce mixed into the aioli changes everything without overwhelming the sweet potato's natural flavor.
  • Cutting your fries with a mandoline saves time and creates perfectly uniform thickness, which means everything cooks at exactly the same rate.
