These homemade vegetable gyoza are packed with cabbage, mushrooms, carrot, and ginger for a savory, satisfying bite. Pan-fried until crisp on the bottom and steamed until tender, they make a great appetizer, light meal, or freezer-friendly make-ahead dish.
If making the wrappers from scratch, combine the flour and salt in a mixing bowl. Gradually pour in the boiling water, stirring with a spoon until a rough dough forms. When cool enough to handle, knead on a lightly floured surface for about 10 minutes until smooth, then wrap and chill for at least 1 hour. You can also use 25 to 30 store-bought gyoza wrappers.
While the dough rests, prepare the filling. Coarsely grate the cabbage, mushrooms, carrot, and water chestnuts, then mix with the ginger, garlic, and spring onions. Heat the sunflower oil in a wok or large frying pan over high heat, add the vegetables, and stir-fry for about 3 minutes until slightly softened.
Add the soy sauce and Shaoxing wine, then cook for another 2 to 3 minutes until the moisture reduces. Taste and season if needed, then transfer the filling to a bowl and let it cool completely before assembling.
Divide the dough in half. Dust the work surface with cornflour and roll out one portion until very thin. Cut out 10 cm rounds and stack them lightly dusted with cornflour so they do not stick together. Re-roll the scraps and repeat until you have about 25 wrappers.
To shape the gyoza, place 1 teaspoon of filling in the center of each wrapper. Lightly moisten the edge with water, fold the wrapper over, and pleat one side while sealing firmly. Arrange the dumplings on a cornflour-dusted tray. At this stage, freeze until firm, then transfer to a freezer bag if storing for later.
To cook, heat a little oil in a nonstick frying pan with a lid. Arrange the gyoza flat-side down and cook for 2 minutes until the bottoms are golden. Pour in 100 ml water, cover immediately, and steam over medium heat for 3 to 5 minutes until the water evaporates and the filling is heated through.
Remove the lid and let the gyoza cook for 1 more minute so the bottoms turn crisp again. Stir together the rice wine vinegar and crispy chilli oil for dipping, then serve the dumplings hot.
Squeeze excess moisture from the grated vegetables if they seem very wet, or the filling can make the wrappers soggy. Store-bought wrappers save time and make shaping easier. Uncooked gyoza freeze well for up to 3 months and can be cooked straight from frozen; just add 1 to 2 extra minutes to the steaming time.
