Steps
Before you start
- Preheat your oven to 400°F (200°C)
- Pat the cod fillets completely dry with paper towels—this helps the miso glaze adhere and the fish cook evenly
- Have all glaze ingredients measured and ready; the cooking moves quickly
Make the miso glaze
- In a small bowl, whisk together the white miso paste, sake, dashi, mirin, and minced ginger until smooth and well combined.
- If the miso is lumpy, press it against the side of the bowl with the whisk.
- The glaze should be pourable but have body.

Ready when: miso is fully dissolved and glaze is smooth and pourable
Tip: Don't skip the whisking—a lumpy glaze won't coat the fish evenly.
Arrange cod and season
- Place the dried cod fillets skin-side down in a 9×13-inch (23×33 cm) baking dish or on a sheet pan lined with parchment paper.
- Arrange them so they don't touch.
- Pat them dry one more time if they've wept moisture.
- Season lightly with salt and white pepper if desired.

Ready when: fish is arranged with space between fillets
Tip: White pepper is traditional in Japanese cooking and won't create dark specks on the delicate fish, but black pepper works too.
Brush glaze onto cod
- Using a pastry brush or the back of a spoon, brush about two-thirds of the miso glaze evenly over the top and sides of each fillet, reserving the remaining glaze.
- Don't leave any bare spots, but don't soak the fish—you want a thin, even coating.

Ready when: all fillets are evenly coated with glaze
Tip: Save the extra glaze to brush on halfway through roasting—it prevents the fish from drying and deepens the flavor.
Roast until cooked throughOven 400°F / 205°C
- Place the baking dish in a preheated 400°F (200°C) oven.
- Roast for 10–12 minutes, depending on fillet thickness (aim for 10 minutes for 1-inch/2.5 cm thick fillets, up to 12 for thicker cuts).
- About halfway through, brush with the reserved glaze.
- The fish is ready when the flesh is opaque, flakes gently with a fork at the thickest part, and registers 145°F (63°C) on an instant-read thermometer inserted into the center.

Ready when: flesh is opaque, flakes with a fork, and reaches 145°F (63°C) internal temperature
Tip: Overcooking cod makes it dry and tough. Use a meat thermometer for insurance—Japanese cooking values precision.
Rest and finish
- Remove the baking dish from the oven and let the fish rest for 2–3 minutes.
- The residual heat continues to cook the thickest parts gently.
- Sprinkle with the white parts of the green onion (if using) and toasted sesame seeds.

Ready when: fish has rested and is ready to serve
Tip: Don't skip the rest—it lets the fish relax and ensures the centers aren't overcooked while edges brown.
Serve
- Transfer each fillet to a warm plate.
- Drizzle any pan juices and remaining glaze over the fish.
- Garnish with the green parts of the green onion (if using).
- Serve immediately with steamed rice and a vegetable side such as bok choy or steamed broccoli.

Tip: Pour the pan juices over the fish—they're liquid gold, full of umami from the miso and sake.
Good to know
Tips
- White miso (shiro miso) is milder and slightly sweet than red miso, making it ideal for fish. It's widely available in supermarkets, Asian markets, and online.
- Drying the fish thoroughly before glazing is critical—moisture prevents proper browning and causes the glaze to slide off.
- The miso glaze will darken and caramelize as the fish roasts, creating a thin, savory crust that protects the delicate flesh.
- This dish is best served immediately, but room-temperature leftovers are also pleasant with a squeeze of fresh lemon or yuzu.
Storage & reheating
Leftovers keep refrigerated in an airtight container for up to 2 days. Reheat gently in a 325°F (163°C) oven for 8–10 minutes with a splash of water to prevent drying. Do not freeze—the delicate texture of the fish will suffer.
Substitutions
- dashi broth (or low-sodium vegetable or chicken broth) → low-sodium chicken or vegetable broth. Dashi adds authentic umami depth, but any light broth works. If substituting, use the same quantity.
- sake (or dry white wine if unavailable) → dry white wine or dry vermouth. Sake brings a subtle sweetness and helps balance the miso. Dry white wine is the closest match; avoid wine with heavy oak.
- mirin (sweet rice wine) → honey or agave nectar. Mirin provides gentle sweetness. If using honey, reduce to 1½ tablespoons as it's sweeter than mirin.
- skinless cod fillets → halibut, sea bass, or flounder fillets of similar thickness. Any firm white fish with mild flavor works. Adjust cooking time if fillets are thicker or thinner than 1 inch (2.5 cm).
