Ingredients

Instructions

  1. Step 1: Heat 4 cups dashi stock in a medium pot over medium-low heat until it just begins to simmer (do not boil).
  2. Step 2: Whisk 3 tbsp white miso paste into 1/4 cup of the hot dashi in a small bowl until smooth, then stir the mixture back into the pot to prevent curdling.
  3. Step 3: Add 1 tbsp dried wakame seaweed and 1/2 cup sliced shiitake mushrooms to the pot, then simmer gently for 3 minutes until wakame softens and mushrooms become tender.
  4. Step 4: Gently place 14 oz cubed tofu into the pot and cook for 2 more minutes until heated through. Remove from heat, stir in 2 sliced green onions, and serve immediately while hot.
