Prepare your workstation by setting out all ingredients, chopping vegetables, and having egg roll wrappers ready. This ensures efficient assembly once your filling is cooked.
Heat 1 tablespoon oil in a large skillet over medium-high heat. Add garlic and ginger, stirring constantly for 30 seconds until fragrant but not browned.
Add ground pork to the skillet and cook for 3-4 minutes, breaking it up with a wooden spoon until no pink remains.
Mix in cabbage and carrots, cooking for 2-3 minutes until vegetables just begin to soften but still maintain some crunch.
Stir in bean sprouts, green onions, soy sauce, rice vinegar, and sesame oil. Cook for 1 additional minute, then remove from heat and stir in white pepper.
Transfer filling to a bowl and let it cool for 5-10 minutes. Hot filling can make the wrappers soggy and difficult to work with.
Preheat your air fryer to 375°F (190°C) for about 3 minutes while you assemble the egg rolls.
Position an egg roll wrapper like a diamond with a corner pointing toward you. Place about 2-3 tablespoons of filling in a line across the center, leaving at least 1 inch of wrapper on each side.
Fold the bottom corner over the filling, then fold in the sides, and roll tightly upward. Dab the top corner with water to seal the egg roll closed.
Lightly brush each egg roll with oil on all sides. This is crucial for achieving that golden-brown exterior.
Place egg rolls in the air fryer basket in a single layer with space between each (likely 3-4 per batch, depending on your air fryer size).
Cook for 7-8 minutes, flipping halfway through, until the egg rolls are golden brown and crispy on all sides.
Transfer finished egg rolls to a cooling rack rather than a plate to maintain crispiness while cooking remaining batches.
Serve immediately with dipping sauce of your choice. These are best enjoyed hot while the wrapper is still crispy and the filling is warm.
