- 1 butternut squash, halved lengthwise and seeded
- 3 tablespoons brown sugar
- 2 tablespoons soy sauce
- 2 scallions, white and pale green parts only, thinly sliced
- 1 teaspoon ginger
- 20 wonton wrappers
- 1/4 cup vegetable oil, divided
- 1 cup water, divided
- Dipping Sauce:
- 1/2 cup soy sauce
- 1/4 cup water
- 1/4 teaspoon sesame seeds
- Place butternut squash cut-side down in a shallow dish; cover with plastic wrap.
- Microwave squash until flesh is easily pierced with a fork, about 12 minutes. Cool until easily handled, about 5 to 10 minutes.
- Scoop squash flesh into a large bowl, discarding skin. Mix brown sugar and 2 tablespoons soy sauce into the squash. Stir in scallions and ginger.
- Spoon 1 tablespoon squash mixture into the center of a wonton wrapper. Moisten edges with water and fold into a triangle. Repeat with remaining wonton wrappers. Arrange filled potstickers on a baking sheet.
- Freeze potstickers until almost solid, about 15 minutes.
- Heat 2 tablespoons oil in a large skillet over medium heat. Add a layer of potstickers; cook, shaking skillet occasionally, until bottoms are golden, about 2 minutes. Flip and add 1/2 cup water. Cover and let steam until cooked through, about 3 minutes. Transfer to a serving dish. Repeat with remaining oil and potstickers.
- Mix 1/2 cup soy sauce, water, and sesame seeds together in a small bowl to make dipping sauce. Serve alongside potstickers.
