Instructions

  1. Step 1: In a medium saucepan, bring 4 cups dashi stock to a gentle simmer over medium-low heat (do not boil). Add 1 slice kombu and 1/4 cup dried shiitake mushrooms, then simmer for 10 minutes to infuse flavors.
  2. Step 2: Remove kombu and mushrooms with a slotted spoon, then stir in 3 tbsp white miso paste until fully dissolved. Add 1/4 tsp white pepper, 1/4 tsp sugar, and 1/4 tsp sesame oil, stirring constantly for 1 minute until well combined.
  3. Step 3: Gently fold in 1/2 cup tofu cubes and 2 thinly sliced green onions, cooking for 2 more minutes until tofu is heated through and greens are just wilted.
  4. Step 4: Taste and adjust seasoning if needed. Serve immediately in warmed bowls while the broth is still hot and aromatic.
