- 1 tablespoon canola oil
- 1 large onion, coarsely chopped
- 2 large garlic cloves, minced
- 8 cups water
- 1/4 cup plus 2 tablespoons doenjang, a Korean soybean paste (see Note), or dark miso
- 2 tablespoons soy sauce
- 1 tablespoon light brown sugar
- 1/2 teaspoon kochukaru, a Korean red pepper powder (see Note), or Aleppo chiles
- 1/2 pound mung bean sprouts
- 1 medium zucchini, very thinly sliced
- 14 to 16 ounces soft tofu, cut into 1/2-inch cubes
- 1 spicy green long chile, preferably Korean, thinly sliced
- Heat the canola oil in a large pot. Add the onion and garlic and cook over moderate heat, stirring occasionally, until softened, about 5 minutes. Add the water and doenjang and whisk until dissolved. Add the soy sauce, brown sugar and kochukaru and bring to a boil. Add the bean sprouts and zucchini and cook until the zucchini is just tender, about 2 minutes. Add the tofu cubes and cook until the tofu is heated through, about 2 minutes. Ladle into bowls, garnish with the sliced chile and serve.
Doenjang and kochukaru are available at Korean and Asian markets.
