Instructions

Step 1
In a large bowl, toss the sweet potato fries with olive oil, smoked paprika, garlic powder, salt, and black pepper until evenly coated.
Step 2
Preheat the air fryer to 200°C (400°F). Arrange fries in a single layer in the air fryer basket; you may need to cook in batches to ensure air circulation.
Step 3
Air fry for 15–20 minutes, shaking the basket halfway through, until fries are crisp and golden.
Step 4
While the fries cook, make the onion dip: Heat 1 tbsp olive oil in a small skillet over medium heat. Add diced onion and sauté for 5–7 minutes until soft and lightly golden.
Step 5
In a medium bowl, mix together sour cream, mayonnaise, sautéed onion, onion powder, garlic powder, chives (if using), salt, and black pepper. Stir until well combined.
Step 6
Serve the hot sweet potato fries immediately with the onion dip on the side for dipping.

Zusatztipps für die Zubereitung

To achieve the best results, avoid overcrowding the air fryer basket. Cooking the fries in a single layer allows the hot air to circulate around each piece, ensuring every fry is evenly crisp. If you have a smaller air fryer, simply cook in two batches.

Varianten und Anpassungen

You can easily customize the dip to your preference. For a lighter version, substitute Greek yogurt for the sour cream. If you enjoy a bit of heat, add a pinch of cayenne pepper to the sweet potato seasoning or directly into the onion dip.

Serviervorschläge

These fries are best served immediately while they are hot and at their peak crispiness. They make a fantastic appetizer for game nights or a colorful side dish for grilled chicken or black bean burgers.
