Miso-Glazed Cod
Roasted Cod with White Miso, Mirin, and Sesame
Tender cod is brushed with a glossy white miso, mirin, sake, and sesame glaze, then roasted and broiled for a savory-sweet Japanese-inspired dinner.
About This Recipe
Miso-Glazed Cod is a weeknight fish dinner with the polish of a restaurant plate. Mild cod takes on a glossy coat of white miso, mirin, sake, soy, maple, ginger, garlic, and sesame oil, then roasts until the center is tender. A quick broil caramelizes the surface so the glaze tastes rounded and savory rather than simply sweet.
Miso is a fermented soybean paste with a long history in Japanese cooking, where it is used to add depth to soups, marinades, dressings, and sauces. Mirin and sake bring the familiar balance of sweetness and aroma, while a small amount of maple syrup gives this version a modern pantry-friendly finish. The result is best understood as Japanese-inspired home cooking: it respects the logic of the classic ingredients while making room for a little North American sweetness.
The marinade is intentionally brief because cod has a delicate texture. Thirty minutes gives the miso mixture time to season the fish without leaving the surface overly salty or soft, and the clean glaze reserved before marinating is what makes the final brush safe and bright. Discard any liquid that touched the raw cod rather than returning it to the saucepan or using it at the table.
Roasting at 425°F (220°C) cooks the fillets gently and keeps the work simple. Pat the cod dry before it goes into the pan, arrange the portions with space between them, and begin checking early because thickness varies. The final broil should be close and quick: watch the sugars carefully, and use 145°F (63°C) at the thickest point as the dependable doneness cue.
Serve the cod with steamed rice, barley, quinoa, or a pile of crisp greens that can catch the lacquered glaze. Bok choy with sesame, quick-pickled cucumber, or daikon ribbons add the cool crunch that keeps the meal balanced. Scatter the green onions and sesame seeds over the fish at the last moment so their freshness and texture remain distinct.
Because the active cooking is short, this is an easy recipe to fit into a busy evening once the fish is marinating. The glaze can be whisked and the garnishes sliced earlier in the day, but keep the cod chilled until it is ready for the oven. Refrigerate leftovers within two hours, use them within three to four days, and reheat gently with a spoonful of water or sauce so the fish stays moist.

Step by Step Instructions
- Make and reserve the glaze Whisk the white miso paste, mirin, sake, soy sauce, maple syrup, ginger, garlic, and toasted sesame oil until smooth, then reserve one-third of the clean glaze in a separate bowl.
- Marinate the cod Coat the cod fillets with the remaining glaze, cover, and refrigerate for 30 minutes; discard the glaze that contacted the raw fish.
- Prepare the oven Heat the oven to 425°F (220°C), line a rimmed sheet pan with foil, and brush the foil with the neutral oil.
- Roast the cod Arrange the cod on the prepared pan and bake for 8 to 10 minutes, until nearly cooked through.
- Broil with the reserved glaze Brush the cod with the reserved clean miso glaze and broil for 1 to 2 minutes, until caramelized and the thickest part reaches 145°F (63°C).
- Finish and serve Finish the Miso-Glazed Cod with the green onions and toasted sesame seeds and serve immediately.

Variations & Serving Suggestions
- Swap cod for black cod, sea bass, or halibut in a similar thickness.
- Serve with steamed rice, barley, quinoa, bok choy, or a crisp cucumber salad.
- Use yellow miso for a slightly earthier glaze, adjusting soy sauce to taste.
- Finish with yuzu, lemon, lime, quick-pickled daikon, or extra sesame seeds.
Storage & Reheating
Cool leftover cod within two hours, transfer it to a shallow airtight container, and refrigerate it at 40°F (4°C) or below for three to four days. Keep the glaze with the fish so it protects the surface while it chills.
Reheat gently in a covered skillet over low heat with a spoonful of water or sauce, stopping as soon as the fish is hot. Avoid a second broil, which can dry the cod and darken the glaze.
Practical Cooking Notes
Measure the clean glaze into a separate bowl before the cod goes into the marinade. It will be ready for the final brush without any raw-fish contact.
A dry surface browns more cleanly and keeps the glaze from sliding off. Use paper towels immediately before arranging the fillets on the pan.
The glaze contains sugars that can move from caramelized to burnt quickly. Stay nearby and pull the fish as soon as the surface is lacquered.
Troubleshooting
The glaze is too dark.
Likely cause: The fish stayed under the broiler too long.
Fix: Broil for only 1 to 2 minutes, keep the pan close at hand, and remove it as soon as the surface caramelizes.
The cod is dry.
Likely cause: The fillets were thin or continued cooking past doneness.
Fix: Start checking early and remove the fish at 145°F (63°C), allowing carryover heat to finish the center.
The fish tastes too salty.
Likely cause: The cod marinated too long or the glaze was reduced too far.
Fix: Keep the marinade to 30 minutes, use the clean reserved glaze for finishing, and avoid extra soy sauce at the table.
Frequently Asked Questions
Can I use another fish instead of cod?
Yes. Choose similar-thickness black cod, sea bass, or halibut fillets and begin checking them at the same time. Cook the thickest part to 145°F (63°C), since the exact timing will change with the cut and density of the fish.
How long can the cod marinate?
Thirty minutes is the ideal window for this recipe, and two hours is the maximum I recommend. Miso and soy sauce continue seasoning the surface as the fish sits, so a much longer marinade can make delicate cod overly salty and soft.
What can replace sake?
Replace the 1 tablespoon sake with 1 tablespoon water plus 1/2 teaspoon rice vinegar. Keep the mirin and maple syrup unchanged so the glaze still has the same balance of sweetness and acidity.
Why do I need to reserve part of the glaze?
The reserved portion never touches raw fish, so it can be brushed on during the final broil. Discard the glaze used for marinating instead of boiling it separately or serving it at the table.
