Serves 4
Prep Time: 20 minutes |
Cook Time: 12 minutes |
Total Time: 32 minutes
Ingredients
- 4 cod fillets about 6 ounces each, skin on or off per preference
- 1/3 cup white miso paste (shiro miso)
- 3 tablespoons mirin
- 3 tablespoons sake (or substitute dry white wine)
- 3 tablespoons granulated sugar or honey
- 1 tablespoon soy sauce or tamari for gluten free
- 1 teaspoon neutral oil for the baking tray
- 2 scallions thinly sliced for garnish
- 1 teaspoon toasted sesame seeds for garnish
- 2 cups cooked jasmine rice and 4 baby bok choy halved for serving, optional
Instructions
- Pat the cod fillets dry with paper towel and set aside, this helps the marinade stick and the fish to caramelize.
- Whisk the white miso paste, mirin, sake, and sugar in a small bowl until smooth and glossy, taste and add 1 tablespoon soy sauce if you like extra depth.
- Spread the miso mixture evenly over the top of each fillet, place the fillets in a shallow container or zip top bag skin side down, cover and refrigerate to marinate for at least 2 hours but preferably overnight for best flavor.
- When ready to cook, preheat the oven to 400 degrees F 200 degrees C and line a baking sheet with foil or parchment, brush lightly with the teaspoon of oil to prevent sticking.
- Wipe off excess marinade gently if it is dripping too much but leave a thin coat on the fish, place fillets on the tray spaced apart, bake on the middle rack for about 10 to 12 minutes until the fish is opaque and flakes easily, the top should be caramelized but watch closely so the sugars do not burn.
- If you want a deeper char, finish under the broiler for 1 to 2 minutes but stay at the oven and watch carefully.
- Let the fillets rest a minute, then sprinkle with toasted sesame seeds and sliced scallions, serve each fillet with a scoop of steamed jasmine rice and charred baby bok choy.

Tips & Tricks
- Pat the fish dry before marinating to help the miso adhere and to get a better crust.
- Marinate longer for deeper flavor but avoid more than 48 hours so the texture does not become overly soft.
- Keep an eye on the sugar in the glaze when baking and move the tray down a rack if the top starts to darken too quickly.
- Warm rice and vegetables before plating so the meal is uniformly hot at the table.
- Use a light oil on the baking tray rather than on the fish to avoid excess smoking.
Serving Ideas
- Simple weeknight dinner with steamed jasmine rice and bok choy
- Elegant date night plated with pickled ginger and a side salad
- Bento style lunch box with rice, pickled vegetables, and a small citrus wedge

Frequently Asked Questions
Can I use other fish for a miso marinade
Yes, salmon or halibut work well with the same marinade though cooking times will vary, keep an eye on thickness.
Do I need sake in the marinade
Sake adds a subtle depth but you can substitute dry white wine or omit it, just adjust salt and sweetness to taste.
How long should I marinate the cod
Marinate at least 2 hours for flavor but overnight up to 48 hours gives the best balance of taste without breaking down the fish.
Can I make the marinade ahead of time
Yes the miso marinade mixes well and can be stored covered in the refrigerator for a few days, stir before using.
