Ingredients

Miso Marinade

  • 1 tbsp gluten free tamari or shoyu (if not gluten free)
  • 1/2 cup mirin
  • 1/2 cup white or yellow miso such as chickpea miso

Cod and Veggies

  • 2 pound cod fillet whole or cut into 4-inch wide portions
  • 6 oz mushrooms such as oyster and shiitake
  • 1 tbsp olive oil
  • 1 tbsp gluten free tamari
  • 1 6-inch piece kombu
  • 5 heads baby bok choy cut in half lengthwise

Instructions

  • Combine the tamari, mirin, and miso in a baking dish. Whisk to form a smooth marinade. Set the fish in the marinade, turning to coat both sides. Marinade at room temperature for 30 minutes or cover and store in the fridge for up to 24 hours.
  • Preheat the oven to broil. Pour the marinade into a bowl and nestle the mushrooms around the fish. Drizzle the olive oil and tamari over the mushrooms. Place on the middle rack for 15 minutes or to your desired doneness. Note that the fish will continue to cook once removed.
  • Place the kombu, 1 cup filtered water, and 1 cup of the reserved miso marinade into a medium skillet. Bring to a simmer over medium-high heat and add the bok choy. Cook for 2 minutes, rotating half-way through just until tender.
  • Serve the cod with the miso-kombu sauce, mushrooms, and bok choy. If you want, you can cut the kombu into strips to make kombu noodles.

Notes

Miso Paste
Look for miso paste labeled "white" "chickpea" or "yellow" for this recipe. If you have a gluten allergy, be sure to check the label.
Kombu
Kombu is a seaweed that expands in water and adds a briny flavor that compliments seafood. It is entirely optional in this recipe. You may use 1 tablespoon bonito flakes instead or 1 Tablespoon of tamari in place of the seaweed.
Storing and Reheating
This fish tastes fantastic the next day. You can rewarm the fish with the vegetables and miso broth in a skillet or microwave covered just until warmed through. Store in the fridge, covered for no more than 2 days.
If making ahead, marinade the fish for up to 24 hours and cook just before assembling.
