Weeknight Miso Black Cod Rice Noodle Bowls (Air Fryer)

If you love restaurant-style miso black cod but want something realistic for a weeknight, this bowl is for you. It is cozy, fast, and layered with flavour without feeling heavy or fussy.

Think tender miso glazed black cod, slurpable rice noodles, crisp vegetables, and just enough broth to bring everything together. It is the kind of dinner that feels special but fits easily into a weeknight rhythm.

This recipe was made in collaboration with Diana’s Seafood. We ordered the black cod and key grocery items for this dish from their Shopify page, then added a couple of pantry staples and some fresh produce. Easy peasy. All opinions in the post are our own.

Instructions

Make the Miso Glaze and Prepare the Cod

In a small bowl, whisk together the white miso, mirin, sugar, rice vinegar, and Japanese chili oil until smooth.

Lightly brush a thin, even layer of glaze onto the flesh side of the cod only. Do not coat the skin.

Let the glazed cod rest at room temperature for 10 to 15 minutes while you prepare the rest of the meal. This allows the flavour to absorb and helps the glaze caramelize during cooking.

Prepare the Cold Cucumber and Radish

In a small bowl, toss the cucumber and radishes with rice vinegar, water and sugar. Set aside to lightly pickle. Drain lightly just before serving.

Make the Miso Soup Base

In a large pot, bring the water and miso soup packets to a gentle boil, whisking until dissolved.

Remove from heat. This broth will be used to soak the noodles and vegetables and to finish the bowls.

Soak the Noodles and Vegetables

Add the rice noodles, broccoli, mushrooms, and baby bok choy to the hot miso soup.

Gently submerge everything. Cover and let stand for 8 to 10 minutes, stirring once halfway through, until noodles are tender but springy and vegetables are just cooked. Keep covered to stay warm.

Optional texture boost: Toss mushrooms and broccoli lightly with oil and air fry at 400°F (200°C) for 7 to 9 minutes until lightly caramelized. Add to bowls during assembly instead of soaking in the soup.

Air Fry the Black Cod

Preheat the air fryer to 400°F (200°C).

Place the cod skin side down on perforated parchment paper in the air fryer basket.

Air fry for 6 to 8 minutes, depending on thickness, until the glaze is lightly caramelized and the fish flakes easily but stays moist. No flipping needed.

Assemble the Bowls

Divide the noodles and vegetables between two bowls using tongs.

Ladle ¼ to ⅓ cup of miso broth (60 to 80 ml) into each bowl, just enough to warm and moisten everything.

Top with the hot miso black cod.

Finish with scallions or chopped cilantro and serve the cold cucumber and radish on the side.

Tips for Success

• Brush the glaze onto the cod first, then prep everything else. This short rest helps the glaze cling and caramelize.
• Use a thin layer of glaze only. Heavy coating can burn and slide off.
• Keep the fish skin side down. The skin protects the flesh and prevents scorching.
• If using a small air fryer, cook vegetables first and keep them warm, then cook the cod last so it stays hot.

Substitutions

• Fish: Sablefish is ideal, but Chilean sea bass works well. Salmon can be used but will be less rich.
• Vegetables: Swap broccoli or bok choy for snap peas, spinach, or napa cabbage.
• Noodles: Rice vermicelli or udon noodles both work nicely.
• Miso: White miso is best. Avoid red miso, which can overpower and burn more easily.

Serving Suggestions

• Add chili crisp or a drizzle of sesame oil for heat and depth.
• This pairs well with a simple citrusy salad or edamame for a fuller meal.
