These vegan potstickers are fun to make and even more fun to eat! Bursting with veggies and spices, crispy on the bottom, soft and sticky on top, they make a delicious appetizer that will be a hit at your next gathering.
Coat the bottom of a medium skillet with 1 tablespoon of oil. Give the oil a minute to heat up, then add the chopped mushrooms in an even layer.
Cook the mushrooms for about 5 minutes, flipping them once or twice, until they're lightly browned. Remove them from the skillet and transfer them to a plate.
Add another tablespoon of oil to the skillet. Give it a minute to heat up, then add the white parts of your scallions, garlic and ginger. Cook everything for about 1 minute, stirring frequently, until very fragrant.
Raise the heat to medium high and add the cabbage, carrots, and water chestnuts. Cook the mixture, stirring frequently, for about 4 minutes, until the vegetables begin to soften.
Return the mushrooms to the skillet. Add the green parts of the scallions, soy sauce, brown sugar, sriracha, sesame oil, cornstarch, and five spice.
Flip the ingredients a few times with a spatula to mix everything up and cook the mixture for about 1 minute more. Remove the skillet from heat.
Taste-test the filling and season it with salt to taste. (Note 2) Adjust any other seasonings to your liking.
Fill a small bowl with water. Set a dumpling wrapper on a work surface and moisten the edges with water. Drop a heaping teaspoonful of the filling in the center of the dumpling.
Fold the wrapper in half over the filing, pinching the wrapper together at the midpoint of the round edge. Seal one side at a time, forming small pleats in the half of the wrapper facing you.
Continue filling and folding the dumplings until all of the filing is used.
Coat the bottom of a medium to large nonstick skillet with oil and place it over medium heat. (Note 3)
Cook the dumplings in batches. Add as many as you can fit in the skillet without crowding, placing them flat (non-pleated) sides down.
Pan-fry the dumplings for about 4 minutes, until golden brown and crispy on the bottoms, then add ¼ to ⅓ cup of water (Note 4) and loosely cover the skillet (Note 5). Be careful when adding the water, as it may sputter when it hits the hot surface.
Steam the dumplings for 3 to 4 minutes, until all of the water has evaporated.
Remove the dumplings from the skillet and continue cooking them in batches in the same manner.
Stir the dipping sauce ingredients together in a small bowl. Make sure to fully dissolve the brown sugar.
Sprinkle the dumplings with sesame seeds and serve them with dipping sauce on the side.
