In a mixing bowl, combine the shredded imitation crab meat, cream cheese, chopped green onion and soy sauce until well-mixed.
Using your hands, scoop about a tablespoon of the mixture and shape it into small balls.
Place the crab rangoon balls on a tray or plate and freeze them for at least 30 minutes.
Once ready for breading: Beat the large egg in a small bowl.
In another bowl, add the grated parmesan cheese for breading.
Dip each frozen crab rangoon ball into the beaten egg, then roll it in the grated parmesan cheese, ensuring the ball is evenly coated.
Preheat your air fryer to 375°F.
Spray each crab rangoon ball with cooking spray and place them in the air fryer basket, ensuring they don't touch.
Air fry for 8-12 minutes or until the balls are golden and crispy outside.
Mix the sweet Thai chili sauce with Sriracha or a spicy dipping sauce.
Serve your crispy crab rangoon balls with the dipping sauce on the side.
