Air Fryer Sweet Potato Fries Recipe: Crispy, Healthy & Irresistible

Craving crispy fries without deep frying? What if you could enjoy golden, crunchy fries with up to 70% less oil compared to traditional deep-fried versions? That’s exactly what this Air Fryer Sweet Potato Fries Recipe delivers—crispy edges, tender centers, and bold flavor using minimal oil and maximum technique.

Sweet potatoes are naturally rich in fiber, vitamin A, and antioxidants, making them a smarter alternative to standard fries. When cooked in an air fryer, they achieve that satisfying crunch without the excess calories. If you’ve struggled with soggy sweet potato fries in the past, this step-by-step guide will transform your results.

Let’s get started.

Introduction

Why do so many homemade sweet potato fries turn out limp instead of crispy—even in an air fryer?

The answer lies in moisture control and starch structure. Sweet potatoes contain more natural sugars and water than regular potatoes, which can prevent crisping. This Air Fryer Sweet Potato Fries Recipe uses a proven method—soaking, drying, and coating lightly with cornstarch—to ensure maximum crispiness every time.

Whether you’re preparing a healthy snack, a side dish for burgers, or meal-prep vegetables for the week, these air fryer sweet potato fries are quick, nutritious, and incredibly satisfying.

Ingredients List

Here’s what you’ll need for perfect Air Fryer Sweet Potato Fries:

Main Ingredients

2 large sweet potatoes (about 1½ pounds)
1–2 tablespoons olive oil (or avocado oil)
1 tablespoon cornstarch (key for crispiness)
½ teaspoon paprika
½ teaspoon garlic powder
½ teaspoon salt
¼ teaspoon black pepper

Optional Seasonings

Cayenne pepper for heat
Smoked paprika for deeper flavor
Cinnamon for a sweet-savory twist
Fresh rosemary or thyme

Substitution Tips

Arrowroot powder instead of cornstarch
Coconut oil spray for lighter coating
Sea salt flakes for enhanced texture

Pro Tip: Choose firm, evenly shaped sweet potatoes for consistent cuts and even cooking.

Timing

Prep Time: 15 minutes
Soaking Time (Optional but Recommended): 30 minutes
Cook Time: 12–15 minutes
Total Time: 30–45 minutes

Compared to oven-baked fries, which can take 45–60 minutes, the air fryer cuts cooking time by nearly 40%.

Step-by-Step Instructions

Step 1: Slice Evenly

Peel (optional) and cut sweet potatoes into evenly sized sticks—about ¼-inch thick.

Uniform thickness ensures even cooking and prevents some fries from burning while others remain soft.

Step 2: Soak for Crispiness

Place cut fries in cold water for at least 30 minutes.

This removes excess surface starch and improves texture.

After soaking, drain and pat completely dry with paper towels. Moisture is the enemy of crispiness.

Step 3: Coat Lightly

Transfer fries to a bowl. Toss with olive oil until lightly coated.

Sprinkle cornstarch evenly and toss again. Add paprika, garlic powder, salt, and pepper.

The cornstarch creates a light outer coating that crisps beautifully in circulating air.

Step 4: Preheat Air Fryer

Preheat your air fryer to 380°F (193°C) for 3–5 minutes.

Preheating helps initiate crisping immediately.

Step 5: Cook in Batches

Place fries in a single layer in the air fryer basket. Avoid overcrowding.

Cook for 12–15 minutes, shaking halfway through.

For extra crispiness, cook an additional 2–3 minutes.

Step 6: Season & Serve

Once golden and crispy, remove fries and season with a pinch of salt while hot.

Serve immediately for best texture.

Reduces initial crisping impact.

Storing Tips for the Recipe
