Ingredients

Instructions

  1. Step 1: Whisk white miso paste, mirin, sugar, and water in a small bowl until completely smooth and no lumps remain. Set aside.
  2. Step 2: Trim bok choy stems and slice into 2-inch pieces; separate leaves. Heat sesame oil in a large skillet over medium-high heat, add minced ginger, and cook for 30 seconds until fragrant but not browned.
  3. Step 3: Add bok choy stems and 2 tbsp water, cover, and simmer for 3 minutes until slightly tender. Add bok choy leaves, cover, and cook for 1 more minute until just wilted.
  4. Step 4: Place cod fillets skin-side down in a shallow baking dish; brush with 1/3 of the miso glaze. Bake at 375°F (190°C) for 12 minutes until the fish is opaque and flakes easily with a fork.
  5. Step 5: Brush remaining miso glaze over cod, return to oven for 3 minutes to caramelize slightly. Plate bok choy, top with cod, and drizzle with reserved glaze. Sprinkle with toasted sesame seeds.
