Sticky Soy Sea Bass & Greens Traybake Recipe
Introduction
This sticky soy sea bass and greens traybake is an easy, flavorful weeknight dinner that combines tender fish with vibrant green vegetables and silky rice noodles. The sweet and savory glaze creates a deliciously sticky finish that’s sure to impress without any fuss.

Ingredients
- 2 tbsp low-salt soy sauce, plus extra to serve (optional)
- 1 tbsp maple syrup or honey
- ½ tsp wasabi paste or 1 tsp Dijon mustard
- 2 tsp sesame seeds, plus a pinch
- 400g green veg medley, such as baby asparagus, quartered pak choi, long-stemmed broccoli, sugar snap peas, and mangetout
- 2 nests rice noodles (100g)
- 4 spring onions, finely sliced
- 2 sea bass fillets
Instructions
- Step 1: Heat the oven to 220°C (200°C fan)/gas mark 7. In a small bowl, whisk together the soy sauce, maple syrup or honey, wasabi paste or Dijon mustard, and 2 teaspoons of sesame seeds to create the sticky dressing.
- Step 2: Place all the green vegetables in a shallow baking tray and toss with 4 tablespoons of water. Roast in the oven for 10 minutes until all the water has evaporated and the greens are tender.
- Step 3: While the greens cook, pour boiling water from the kettle over the rice noodles in a heatproof bowl, covering them completely. Let the noodles soak while you finish the traybake.
- Step 4: When the greens are tender, drizzle half of the soy dressing mixed with 1 tablespoon of water over them along with half the spring onions. Toss well to coat evenly.
- Step 5: Place the sea bass fillets skin-side up on top of the greens. Pour the remaining soy dressing over the fish and sprinkle a pinch of sesame seeds on the skin.
- Step 6: Return the tray to the oven and cook for 5-6 minutes until the fish is cooked through and flakes easily with a fork.
- Step 7: Drain the rice noodles and add them to one side of the tray, coating them in some of the sauce. Drizzle extra soy sauce over the noodles if you like, then scatter the remaining spring onions on top before serving.
Tips & Variations
- For a spicier kick, add a small drizzle of chili oil or sprinkle red pepper flakes over the fish before baking.
- Swap sea bass for other firm white fish such as cod or haddock if preferred.
- Use honey instead of maple syrup for a different sweetness profile.
- Try using different green vegetables depending on what’s in season or available in your pantry.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in the oven or microwave until warmed through, taking care not to overcook the fish. Rice noodles can become sticky after refrigeration, so toss with a little sesame oil or soy sauce before serving again.

FAQs
Can I use fresh noodles instead of dried rice noodles?
Yes, fresh rice noodles can be used. Since they are already cooked, add them to the tray towards the end of the cooking time to warm through without becoming mushy.
What can I substitute for wasabi paste?
If you don’t have wasabi paste, Dijon mustard works well and provides a mild tangy heat that complements the soy glaze.

Instructions
- Prepare the sauce: In a small bowl, whisk together the low-salt soy sauce, maple syrup or honey, wasabi paste or Dijon mustard, and 2 teaspoons of sesame seeds until well combined and set aside.
- Preheat and steam greens: Heat the oven to 220°C (200°C fan) or gas mark 7. Place all the green vegetables in a shallow baking tray and toss with 4 tablespoons of water. Put the tray in the oven and cook for 10 minutes, or until all the water has evaporated and the greens are tender.
- Soak the noodles: While the greens cook, place the rice noodles in a heatproof bowl and cover with boiling water from the kettle. Let them soak until softened as you finish preparing the traybake.

Notes
- Using low-salt soy sauce helps control sodium content without compromising flavor.
- Wasabi paste adds heat and a subtle kick, but Dijon mustard can be used as a milder alternative.
- Soaking rice noodles in boiling water softens them quickly without needing to cook separately.
- Ensure the sea bass skin is placed skin-side up to crisp slightly during baking.
- Use a medley of green vegetables to add variety in texture and nutrition.
- Adjust the amount of soy sauce drizzled at the end to suit your taste preference.
