Ingredients
- 4 6-oz Black cod fillets
- 1/4 cup White miso paste
- 2 tbsp Coconut aminos (or low sodium soy sauce)
- 2 tbsp Rice vinegar
- 3 tbsp Maple syrup
- 4 cloves Garlic (minced)

Instructions
- Step 1: Pat the black cod fillets dry with a paper towel and place them in a shallow baking dish or a large zip lock bag.
- Step 2: In a small bowl, whisk together the miso paste, coconut aminos, rice vinegar, maple syrup, and minced garlic. Pour the marinade over the fish and turn to coat evenly. Cover with plastic wrap or seal the bag, and marinate for 30 minutes.

- Step 4: Heat the avocado oil in a large cast iron skillet over medium heat until it shimmers. Add the cod, skin side up, shaking off any excess marinade. Sear for 2-3 minutes until a browned crust forms on the bottom.
- Step 5: Flip the fish and sear for another 2-3 minutes until the skin is crispy.
- Step 6: Transfer the skillet to the oven and bake the black cod for 2-4 minutes, until the internal temperature reaches 135-140 degrees F (57-60 degrees C) or the fish flakes easily with a fork.
Tips & Variations
- For a gluten-free version, ensure you use coconut aminos instead of soy sauce.
- If you can’t find black cod, sablefish or even a thick white fish like halibut can be used as a substitute.
- Marinate the fish for longer (up to 2 hours) for a more intense flavor.
- Serve with steamed rice and sautéed greens for a complete meal.
Storage
Store leftover miso black cod in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet over low heat or in a warm oven to preserve the texture and flavor. Avoid microwaving as it may dry out the fish.

FAQs
Can I prepare the marinade in advance?
Yes, you can whisk the marinade ingredients together and store it in the refrigerator for up to 3 days. Just add the garlic fresh if possible to maintain its bright flavor.
What if I don’t have a cast iron skillet?
You can use any oven-safe frying pan that can withstand high heat. Just make sure it’s hot enough to sear the fish and can go into the oven safely.

Ingredients
Fish
- 4 6-oz black cod fillets
Marinade
- 1/4 cup white miso paste
- 2 tbsp coconut aminos (or low sodium soy sauce)
- 2 tbsp rice vinegar
- 3 tbsp maple syrup
- 4 cloves garlic, minced
For Cooking
- 1 tbsp avocado oil
Instructions
- Prepare the Fish: Pat the black cod fillets dry with a paper towel to remove any moisture. Place them in a shallow baking dish or a large zip lock bag for marinating.
- Make and Apply Marinade: In a small bowl, whisk together the white miso paste, coconut aminos, rice vinegar, maple syrup, and minced garlic until smooth. Pour this marinade over the cod fillets and turn them to coat evenly. Cover the dish with plastic wrap or seal the bag tightly, then refrigerate to marinate for 30 minutes to allow flavors to penetrate.
- Preheat Oven: Preheat your oven to 400°F (204°C) to prepare for the finishing bake after searing.
- Sear the Cod – First Side: Heat the avocado oil in a large cast iron skillet over medium heat until it shimmers. Remove the cod from the marinade, shaking off any excess, and place in the skillet skin side up. Sear for 2-3 minutes, allowing a golden brown crust to form on the bottom surface.
- Sear the Cod – Second Side: Carefully flip the fillets to sear the other side for another 2-3 minutes, ensuring the skin becomes crispy and the exterior is nicely caramelized.
- Bake to Finish: Transfer the seared cod fillets from the skillet to the preheated oven. Bake for an additional 2-4 minutes until the internal temperature reaches 135-140°F (57-60°C) or the fish flakes easily with a fork, signaling it is perfectly cooked through.
Notes
- Marinating the fish for longer than 30 minutes is possible but avoid exceeding 1 hour to prevent the miso flavors from becoming too strong or the fish texture from becoming mushy.
- If you don’t have coconut aminos, low sodium soy sauce is a great substitute.
- Use a cast iron or heavy-bottomed skillet to get the best sear and crust on the fish.
- Check the internal temperature with a food thermometer to avoid overcooking the delicate cod.
