Prep the air fryer. Preheat to 375°F (190°C) for 3–5 minutes. A hot basket helps the wontons crisp fast.
Make the filling. In a bowl, mix softened cream cheese, chopped crab, green onions, garlic, Worcestershire, soy sauce, sugar, a pinch of salt, and pepper. Stir until smooth and well combined.
Set up your station. Lay out wonton wrappers, a small bowl of beaten egg or water, and the filling with a teaspoon.
Add the filling. Place about 1–1.5 teaspoons of filling in the center of each wrapper. Don’t overfill or they’ll burst.
Seal the wontons. Brush the wrapper edges with egg or water.Fold into a triangle, pressing out air as you seal. For the classic “star” shape, bring the two side corners toward the center and pinch. Make sure all seams are tight. Lightly oil. Brush or spray each wonton with a thin coat of oil on both sides. This is key for even browning.
Air fry in batches. Arrange wontons in a single layer in the basket, leaving space between them. Cook for 6–8 minutes, flipping halfway, until golden and crisp. Time varies by air fryer; check at the 5-minute mark.
Serve hot. Let them cool for a minute—filling will be very hot—then plate with your favorite dipping sauce.
