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.
03 - Position a spring roll wrapper on a clean surface in a diamond orientation. Place 2 tablespoons of cooled filling near the bottom corner. Fold the corner over filling, roll halfway, fold in both sides tightly, and continue rolling to the top edge. Brush final edge with cornstarch slurry to seal. 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 within the air fryer basket, cooking in batches if necessary to avoid overcrowding.
06 - Air fry for 7–8 minutes, carefully flip each roll, then continue air frying for 5–7 minutes until 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 - Serve spring rolls immediately while hot and crispy, accompanied by the prepared dipping sauce.
