The secret to achieving restaurant-quality sweet potato fries at home lies in a few simple techniques: soaking the fries to remove excess starch, coating them lightly with cornstarch for extra crispiness, and cooking them in a single layer in the air fryer. The result is a batch of perfectly crispy fries with tender, sweet interiors that pair beautifully with the creamy, garlicky aioli.

Ingredients

• 2 large sweet potatoes (about 800 g)
• 2 tablespoons olive oil
• 1 teaspoon smoked paprika
• 1/2 teaspoon garlic powder
• 1/2 teaspoon fine sea salt
• 1/4 teaspoon black pepper
• 1 tablespoon cornstarch (optional, for extra crispiness)
• 1/2 cup mayonnaise
• 1 clove garlic, finely minced or grated
• 1 teaspoon lemon juice
• 1/2 teaspoon Dijon mustard
• Salt and black pepper, to taste

Instructions

Step 1

Peel the sweet potatoes and cut them into 1/4-inch thick fries.

Step 2

Place the fries in a bowl of cold water and soak for 20 minutes to remove excess starch. Drain and pat completely dry with a kitchen towel.

Step 3

Toss the fries with olive oil, smoked paprika, garlic powder, salt, pepper, and cornstarch (if using) until evenly coated.

Step 4

Preheat your air fryer to 200°C (400°F) for 3 minutes.

Step 5

Arrange the fries in a single layer in the air fryer basket (cook in batches if necessary).

Step 6

Air fry for 15-20 minutes, shaking the basket halfway through, until fries are golden and crisp.

Step 7

While the fries cook, mix mayonnaise, minced garlic, lemon juice, Dijon mustard, salt, and pepper in a small bowl. Adjust seasoning to taste.

Step 8

Serve the hot sweet potato fries immediately with garlic aioli on the side.

Zusatztipps für die Zubereitung

The key to perfectly crispy sweet potato fries is removing as much moisture as possible before air frying. Don't skip the soaking step—it removes excess starch that can prevent crisping. After soaking, make sure to pat the fries completely dry with a kitchen towel. If your air fryer basket is small, cook the fries in batches rather than overcrowding, which creates steam instead of crisp. Shake the basket halfway through cooking to ensure even browning on all sides. For the aioli, use fresh garlic rather than garlic powder for the best flavor, and adjust the lemon juice and seasoning to your taste preferences.

Varianten und Anpassungen

This recipe is wonderfully adaptable. For spicier fries, add a pinch of cayenne pepper to the seasoning mix. If you prefer a lighter aioli, substitute the mayonnaise with Greek yogurt—it will be tangier but equally delicious. You can also experiment with different seasonings: try adding cumin and chili powder for a southwestern twist, or cinnamon and a touch of brown sugar for a sweet version. For a vegan option, use vegan mayonnaise for the aioli and ensure all other ingredients are plant-based. The fries are best enjoyed fresh, but leftovers can be reheated in the air fryer for 3-4 minutes to restore their crispiness.

Serviervorschläge

These air fryer sweet potato fries are incredibly versatile. Serve them as a side dish alongside burgers, grilled chicken, or fish. They make an excellent appetizer for game day or parties—simply multiply the recipe and set out the garlic aioli for dipping. For a complete meal, pair them with a fresh green salad and your favorite protein. You can also offer additional dipping sauces alongside the aioli: try ketchup, spicy mayo, or a chipotle sauce for variety. Garnish with fresh herbs like parsley or chives for an elegant presentation.
