Preheat the air fryer: Set it to 350°F (180°C) for 3–5 minutes. A preheated basket helps the sticks crisp evenly.
Prepare the crab sticks: Unwrap each stick. Gently separate or “shred” them into thin strands or strips by pulling along the grain.
If you prefer thicker bites, cut each stick into 3–4 pieces instead.
Pat dry: Use paper towels to remove excess moisture. Dry surfaces crisp better and prevent steaming.
Season: In a bowl, toss the crab sticks with oil, garlic powder, paprika, pepper, and salt. Add sugar or chili flakes if using. Coat evenly but lightly—too much oil can soften the texture.
Arrange in the basket: Place the crab sticks in a single layer.
Some slight overlap is fine, but avoid packing them tightly. Crowding reduces crispiness.
Air fry: Cook at 350°F (180°C) for 6–9 minutes. Shake or toss halfway through. For extra crispness, finish at 375°F (190°C) for the last 1–2 minutes.
Check doneness: They should be golden at the edges and dry-crisp to the touch.
If they’re still soft, add 1–2 more minutes.
Serve: Let them cool for 1–2 minutes—they firm up slightly as they rest. Squeeze with lemon and serve with your favorite dip.
