Let’s Make Air Fryer Sweet Potato Fries!

This is one of our favorite quick sweet potato fry recipes. It’s an excellent alternative to oven baking when you want faster results and crispier edges. The fries are lightly coated with oil, seasoned salt, garlic powder, and a bit of cornmeal for texture. They come out golden and crunchy without excessive oil, making them a great side, snack, or even a simple main when paired with a dip or sandwich.

Ingredients You Need

This recipe uses five straightforward ingredients. You will need:

  • Sweet potato: 1 large sweet potato, washed (skin on is optional) and cut into thin French-fry style slices.
  • Oil: 1 tablespoon olive oil (or avocado oil if preferred).
  • Seasoning: 1/2 tablespoon seasoned salt and 1/2 teaspoon garlic powder.
  • Crunch: 1 tablespoon cornmeal to help crisp the exterior.

Flavor idea!

If you don’t have seasoned salt, feel free to swap in other spices you enjoy — black pepper, smoked paprika, or even a pinch of cinnamon for a sweeter twist. You can also use a prepared spice blend like fajita, cajun, or taco seasoning to vary the flavor profile.

How to Make Sweet Potato Fries in the Air Fryer

Note: For the recipe measurements and a concise instruction list, see the recipe card below.

Preheat Air Fryer

Preheat the air fryer to 400°F (204°C). Lightly spray or brush the air fryer basket with non-stick spray or a small amount of oil so the fries don’t stick.

Chop Sweet Potato

Wash the sweet potato and pat it thoroughly dry. Using a sharp knife, slice the sweet potato into even fries about 1/4-inch thick. We prefer leaving the skin on for texture and nutrients, but peeling is optional.

Should I soak my sweet potato fries first? Soaking is not necessary for this recipe and adds an extra step. Patting the fries dry after washing is more important to reduce moisture and help them crisp.

Season Sweet Potato Fries

Place the cut fries in a bowl and drizzle with the olive oil. Sprinkle seasoned salt, garlic powder, and cornmeal over the fries. Toss gently until the fries are evenly coated with oil, spices, and cornmeal.

Air Fry

Cook the fries in batches so they form a single layer in the basket without overcrowding. Depending on the size of your air fryer, you’ll likely cook about half the batch at a time.

Flip & Fry Again

Air fry at 400°F for 4 minutes, then flip the fries and cook for an additional 4–6 minutes, or until they are golden brown and crisp. Timing will vary by air fryer and by the thickness of your fries.

Time Variations

If you cut thicker wedges instead of thin fries, increase the cook time to ensure the centers are cooked through. Watch your first batch closely so you can dial in the ideal time for your specific air fryer.

Repeat

Repeat the process until all fries are cooked. Keep finished fries warm in a low oven if needed while you finish remaining batches.

Serve & Enjoy

Serve hot with ketchup or your favorite dipping sauce and enjoy the crispy, tender results.

Dipping Sauces for Sweet Potato Fries

Ketchup is a classic choice, but these fries pair well with multiple dips: a tangy yogurt-based dip, creamy ranch, honey mustard, or a green goddess-style dressing. Experiment to find your favorite pairing.

how to make

Baked Sweet Potato Fries (Oven Method)

If you prefer the oven, you can bake sweet potato fries at a high temperature until crisp — typically about 25–30 minutes depending on thickness — flipping once for even browning.

Cutting Sweet Potato Fries

We recommend cutting fries into uniform 1/4-inch rectangles for even cooking and a great balance of crispy exterior and tender interior. A very sharp knife helps you get consistent pieces; uniform thickness is the key to even results.

#1 tip

Use a sharp knife and try to make the fries as uniform in size as possible so they cook evenly in the air fryer.

Seasoning Variations

These fries are versatile. Substitute seasoned salt and garlic powder with any of your favorite spice blends in a 1:1 ratio: fajita seasoning, cajun seasoning, Moroccan spice mix, or taco seasoning all work well.

Q&A

Why are my sweet potato fries soggy in the air fryer?

Sogginess is usually caused by moisture. Make sure you pat the sweet potatoes dry after washing and avoid overcrowding the basket so steam can escape.

Why won’t my sweet potato fries get crispy?

To get crispy fries, allow space between pieces in the basket so hot air circulates. The cornmeal in this recipe also helps create a crisp outer texture.

Is it necessary to soak sweet potato fries before air frying?

Soaking is optional. It can reduce surface starch but is not required. If you soak, be sure to dry the potatoes thoroughly before seasoning and cooking.

Storage Instructions

These fries are best served immediately, while hot and crisp. Leftovers can be stored in an airtight container in the refrigerator for 2–3 days.

To reheat: Spread leftover fries on a baking sheet, drizzle lightly with oil, and bake at 450°F until they crisp up again. Reheating in the air fryer for a few minutes also restores crispness.
