Put the pork, soy sauce, garlic, ginger, oyster sauce, Shaoxing wine, sesame oil, green onions, salt and pepper into a large bowl and mix well. I use my hands for the quickest and easiest approach.
1 lb ground pork, 1.5 Tbsp soy sauce, 1 clove garlic, 1/2 inch piece ginger, 2 tsp oyster sauce, 1 Tbsp Shaoxing wine, 2 tsp sesame oil, ¼ cup chopped green onions, ½ tsp fine salt, ½ tsp pepper
Half fill another bowl with room temperature water. Working with one dish at a time, briefly dip a dumpling wrapper in the water and lay it in the base of your dish. Spread a couple of tablespoons of the pork mixture over the dumpling wrapper, squishing it out so it goes right to the edges. Repeat with more dumpling wrappers (dip each into the water before putting into the dish) and more pork, so you have three layers of pork and four dumpling wrappers in each dish. You'll finish with a dumpling wrapper on top. Repeat for all 6 dishes.
24 round dumpling wrappers
Carefully pour a tablespoon of water over the top of each dish, tilting so it goes down the sides of the dish rather than sitting on top.
Preheat your oven to Steam, 212°F/100°C, 100% humidity. While the oven heats, put all your dishes onto a large perforated tray so it's easier to transfer them in and out of the oven.
Put the tray into the hot oven, and cook the dumpling lasagnes until the meat is cooked through, about 20 minutes.
Remove the finished lasagnes from the oven, top with chilli crisp and extra soy sauce, and a few snipped chives or green onions. Serve immediately, scooping down to the bottom of the dish to get the soupy, saucy liquid as well as the meat and dumpling layers on top.
