Background & Inspiration

Miso, a fermented soybean paste, has been a staple of Japanese cuisine for centuries. It’s prized for its deep umami flavor that enhances even the simplest dishes. Glazing fish with miso is a classic Japanese technique, traditionally used with black cod, providing a sweet-savory coating that complements the delicate texture of the fish.

Brussels sprouts, often roasted to bring out their natural sweetness, pair beautifully with miso-glazed fish. This dish combines traditional Japanese flavors with modern roasting techniques, creating a simple, nutrient-rich, and restaurant-worthy meal right at home.

Ingredients & Equipment

For the Miso Glaze:

3 tbsp white miso paste
1 tbsp soy sauce or tamari
1 tbsp honey or maple syrup
2 tbsp mirin or rice vinegar
1 tsp grated fresh ginger
1 clove garlic, minced

For the Cod & Vegetables:

4 cod fillets (approx. 150–200 g / 5–7 oz each)
400 g (14 oz) Brussels sprouts, trimmed and halved
2 tbsp olive oil
Salt and freshly ground black pepper, to taste
1 tsp sesame seeds (optional, for garnish)
2 tbsp sliced green onions (optional, for garnish)

Equipment:

Baking sheet or roasting pan
Small bowl for glaze
Whisk or spoon
Aluminum foil or parchment paper

Pro Tip: For easier cleanup and even roasting, line the baking sheet with parchment paper.

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat the oven to 200°C (400°F). Prepare a baking sheet with parchment paper for both the cod and Brussels sprouts.

Step 2: Prepare the Miso Glaze

In a small bowl, whisk together miso paste, mirin (or rice vinegar), soy sauce, honey (or maple syrup), ginger, and garlic until smooth. Adjust sweetness or saltiness to taste.

Step 3: Roast the Brussels Sprouts

Toss the halved Brussels sprouts with olive oil, salt, and pepper. Spread them on one side of the baking sheet and roast in the preheated oven for 15 minutes, flipping halfway for even caramelization.

Step 4: Glaze the Cod

While the Brussels sprouts begin roasting, brush the cod fillets generously with the miso glaze. Ensure the fillets are evenly coated for a flavorful caramelized finish.

Step 5: Bake Cod with Brussels Sprouts

After 15 minutes, push the Brussels sprouts to one side of the sheet (or use a second sheet if needed) and place the glazed cod fillets on the other side. Bake for 12–15 minutes, until the fish flakes easily with a fork and the glaze is slightly caramelized.

Step 6: Garnish and Serve

Remove the sheet from the oven and transfer cod fillets and Brussels sprouts to plates. Sprinkle with sesame seeds and sliced green onions if desired. Serve immediately, pairing with steamed rice, quinoa, or a light salad for a complete meal.

Expert Tips & Troubleshooting

Avoid burning the glaze: Keep an eye on the cod during baking; miso glaze can caramelize quickly.
Even roasting: Cut Brussels sprouts in similar sizes for uniform cooking.
Extra crispiness: Roast the sprouts at the edge of the pan for better caramelization.
Make-ahead: Prepare the glaze and trim vegetables in advance to reduce cooking time.
Flavor variation: Add a splash of lemon juice after baking for brightness.

Serving Suggestions

Serve with steamed jasmine rice or brown rice for a balanced meal.
Pair with a light miso soup or cucumber salad for a Japanese-inspired dinner.
Add a drizzle of sesame oil for additional depth and aroma.
Garnish with pickled ginger or radish slices for a fresh contrast.

Variations & Customizations

Protein swap: Use salmon, halibut, or tilapia in place of cod.
Vegetable swap: Replace Brussels sprouts with asparagus, green beans, or broccoli.
Sweet alternative: Maple syrup can replace honey for a vegan-friendly glaze.
Spicy touch: Add a pinch of chili flakes or Sriracha for mild heat.
Herbal twist: Garnish with fresh cilantro or parsley instead of green onions.

Make-Ahead & Storage Tips

Refrigeration: Store leftovers in an airtight container for up to 2 days. Reheat gently in the oven to preserve texture.
Do not freeze cooked fish: Freezing can alter texture; it’s best enjoyed fresh.
Reheating vegetables: Roast briefly in a 180°C (350°F) oven to restore crispness.
