When it comes to easy weeknight dinners, nothing beats a one-pan seafood bake or sheet-pan fish dinner. Cooking your fish and vegetables together saves time, keeps cleanup to a minimum, and lets all those rich, savory juices blend together seamlessly. However, the secret to a perfect one-pan meal comes down to timing: matching your vegetables to the quick cooking time of fresh fish.
At Thompson’s Seafood in Holcombe Market, Tottenham (N17), master fishmonger James and the team love sharing practical cooking tips so you can get maximum flavor out of your daily Billingsgate catches with minimal effort.
Perfect Fast-Cooking Veggies for Fish
Most fish fillets—like sea bass, cod, salmon, and sea bream—take between 10 to 15 minutes to cook through. To ensure your entire meal is ready at the exact same time without overcooking the fish or leaving the vegetables raw, choose quick-cooking greens and crisp produce:
Cherry Tomatoes: As they roast, they burst and release natural juices that create a instant, delicious sauce for white fish.
Asparagus & Tenderstem Broccoli: These slender green vegetables roast to a tender-crisp perfection in under 12 minutes.
Bell Peppers & Fennel: Thinly sliced peppers add sweetness, while fennel brings a subtle anise flavor that pairs beautifully with ocean-fresh seafood.
Bok Choy: Ideal for Asian-inspired fish bakes, tender bok choy wilts quickly while keeping a delightful crunch in its stems.
What About Root Vegetables & Potatoes?
If you want to serve your fish with hard root vegetables, sweet potatoes, or baby new potatoes, there is a simple trick to keep your fish from drying out:
Pre-cook Your Potatoes: Sturdier vegetables take 25 to 30 minutes to roast. Start your potatoes or root veggies in the oven 10 to 15 minutes prior to adding the fish to the pan.
Combine for the Finish: Once the potatoes are partially tender, nestle your fish fillets onto the hot tray and return it to the oven so everything finishes together perfectly.
Easy 15-Minute Sheet-Pan Fish Recipe Idea
Arrange Your Tray: Place fresh sea bass or cod fillets from Thompson's Seafood in the center of a baking tray. Surround with halved cherry tomatoes, asparagus spears, and thinly sliced fennel.
Season & Oil: Drizzle olive oil over the fish and veggies. Season with salt, cracked black pepper, fresh lemon juice, and a splash of white wine.
Bake: Roast at 200°C (180°C Fan) for 12 to 15 minutes until the fish flakes effortlessly with a fork and the vegetables are tender.
