01 - Heat sesame oil in a large skillet over medium heat. Add minced garlic and grated ginger, sautéing for 1 minute until fragrant and aromatic.
02 - Add shredded cabbage, julienned carrot, and sliced green onions to the skillet. Cook for 3–4 minutes until vegetables begin to soften. Stir in bean sprouts, soy sauce, and black pepper. Sauté for an additional 2 minutes, then remove from heat and allow filling to cool completely before wrapping.
03 - Position a spring roll wrapper on a clean work surface in a diamond orientation. Place 2 tablespoons of cooled filling near the bottom corner. Fold the corner over the filling, roll halfway, then fold in both sides tightly. Continue rolling to the top edge and brush with cornstarch slurry to seal completely. Repeat with remaining wrappers and filling.
04 - Preheat air fryer to 390°F for optimal crisping.
05 - Lightly coat all sides of spring rolls with oil spray. Arrange in a single layer in the air fryer basket, ensuring space between each roll for proper air circulation. Cook in batches if necessary to avoid overcrowding.
06 - Air fry for 7–8 minutes, carefully flip each spring roll, then continue air frying for another 5–7 minutes until evenly golden brown and crispy throughout.
07 - Whisk together soy sauce, rice vinegar, sugar, and chili flakes in a small bowl until sugar completely dissolves.
08 - Transfer spring rolls to a serving platter and serve hot while crispy, accompanied by the prepared dipping sauce.
