To make the filling, in a bowl, combine the ground chicken, oyster sauce, dark soy sauce, and sesame oil. Add the egg and cornstarch—the egg helps keep the filling tender, while the cornstarch helps lock in moisture and creates that crispy golden bottom. Add the carrots, cabbage, and scallions, then mix until fully combined and slightly sticky.
To assemble the blanket dumplings, add the cooking oil. Instead of folding each dumpling one by one, simply scoop the filling directly into the pan, then cover each portion with a wonton wrapper like a blanket. This shortcut makes them much faster than traditional dumplings.
To pan-fry the blanket dumplings, over medium heat, pan-fry for about 1 minute until the bottoms begin to set. At this stage, we just want a light crust started underneath.
To steam the blanket dumplings, carefully add the water to the pan, cover, and steam for about 5 minutes until the chicken is cooked through. This step helps cook the filling quickly while keeping everything moist. The internal temperature should reach at least 165°F (74°C).
To crisp the bottoms, uncover the pan and continue cooking for about 2 minutes until the bottoms turn golden brown and crispy.
To serve, turn off the heat and top with the scallions. Drizzle with the soy sauce and chili oil before serving.
