The Ultimate Guide to Crispy Air Fryer Sweet Potato Fries

Sweet potato fries are a delicious, nutrient-dense alternative to regular french fries. However, making them at home often results in soggy, limp fries instead of the crispy restaurant-style version. The solution is cooking them in the air fryer! With a few simple tricks, you can make perfectly crispy, lightly seasoned sweet potato fries with very little oil.

The Secrets to Crispy Sweet Potato Fries

1. Cut Them Evenly: Keep the fries relatively thin and uniform in size so they cook at the same rate.
2. Soak in Cold Water: Soaking the cut potatoes in cold water for 30 minutes draws out excess starch, which is the key to getting a crispy exterior.
3. Dry Thoroughly: After soaking, dry the potatoes completely. Any moisture left will steam them in the air fryer, making them soggy.

Ingredients You’ll Need

• Sweet Potatoes (2 medium): Peeled and cut into 1/4-inch fries.
• Cornstarch (1 tbsp): Adds an extra layer of crunch (optional, but highly recommended).
• Olive Oil (1.5 tbsp): Helps them crisp up.
• Garlic Powder & Paprika (1/2 tsp each): For seasoning.
• Salt & Pepper: To taste.

Step-by-Step Instructions

1. Soak and Dry: Cut the sweet potatoes into fries and soak them in a bowl of cold water for 30 minutes. Drain, rinse, and dry them thoroughly with paper towels.
2. Toss with Cornstarch: Place the dry fries in a bowl. Dust them with cornstarch and toss until they are lightly coated.
3. Oil & Season: Drizzle with olive oil, garlic powder, paprika, and black pepper. (Do not add salt yet! Salting before cooking draws out moisture and leads to sogginess).
4. Air Fry: Place in the air fryer basket in a single layer. Air fry at 380°F (190°C) for 15 to 18 minutes, shaking the basket every 5 minutes to ensure even cooking.
5. Salt & Serve: Remove the fries, sprinkle with sea salt immediately, and serve warm.
