Prepare the cabbage by sprinkling it with ½ teaspoon salt and letting it sit for 10 minutes. Squeeze out excess moisture using a clean kitchen towel or paper towels – this prevents soggy dumplings!
Mix the filling by combining ground chicken, drained cabbage, green onions, garlic, ginger, soy sauce, sesame oil, and white pepper in a large bowl. Stir in one direction until well combined and slightly sticky.
Set up a dumpling assembly station with a small bowl of water, dumpling wrappers, and your filling. Keep unused wrappers covered with a damp cloth to prevent drying.
Fill each wrapper by placing about 1 tablespoon of filling in the center. Don’t overfill or they’ll burst during cooking!
Seal the dumplings by dipping your finger in water and running it along half the edge of the wrapper. Fold the wrapper over to create a half-moon, then pinch the center together.
Create pleats by making 3-4 small folds along each side, working from the center toward the edges. This creates the classic potsticker shape. Don’t worry if they’re not perfect—they’ll still taste amazing!
Heat 1 tablespoon oil in a large non-stick skillet over medium-high heat until shimmering.
Arrange potstickers in a single layer in the hot pan, flat side down. Work in batches to avoid overcrowding.
Fry for 2-3 minutes until the bottoms turn golden brown and crispy.
Add ¼ cup water to the pan (it will sizzle!) and immediately cover with a lid. Reduce heat to medium and steam for 5-6 minutes until the filling is fully cooked.
Remove the lid and cook for another minute to allow any remaining water to evaporate. Transfer to a serving plate.
Mix all dipping sauce ingredients in a small bowl and serve alongside your hot, crispy potstickers.
