- 2 tablespoons vegetable oil
- 6 medium shlitake mushrooms, stems removed, caps sliced ¼ inch thick
- Kosher salt
- 6 cups Dashi
- ½ cup plus 1 tablespoon yellow miso paste
- 4 ounces soft bean curd in small dice, at room temperature
- 3 scallions, sliced very thinly on the blas
- Heat the oil in a medium skillet over medium heat. Add the mushrooms and gently cook without browning them, stirring occasionally, until tender and just cooked through, about 5 minutes. Season lightly with salt, remove from the heat, and set aside.
- Bring the dashi to a bare simmer in a medium saucepan. Stir in the miso paste, mashing it against the sides of the pot to help it dissolve. Keep the soup at no more than a bare simmer.
- Divide the mushrooms, bean curd, and scallions among six small soup bowls. When ready to serve, divide the soup among the bowls, top with lids if possible, and pass immediately.
