Introduction
This lemon butter baked white fish is a light and flavorful dish perfect for a wholesome dinner. Paired with tender new potatoes and vibrant shredded hispi cabbage, it offers a delightful blend of fresh, zesty, and buttery flavors that are easy to prepare.

Ingredients
- 2 fillets sustainable white fish
- 1 lemon, ½ thinly sliced and ½ cut into 2 wedges
- 25g butter
- 300g new potatoes, halved
- 1 tbsp olive oil
- 1 red pepper, deseeded and thinly sliced
- 1 yellow pepper, deseeded and thinly sliced
- 1 carrot, julienned or finely sliced
- 2 garlic cloves, finely grated or crushed
- ½ tsp chilli flakes
- A few thyme sprigs, leaves picked
- 250g hispi cabbage, cored and finely sliced
- Chopped parsley, to serve (optional)
Instructions
- Step 1: Heat the oven to 180°C/160°C fan/gas mark 4. Place the fish fillets in a roasting tray, season with salt and pepper, then lay the thin lemon slices on top. Dot the butter evenly over the fish. Bake for 15–20 minutes until cooked through and flaky.
- Step 2: While the fish bakes, put the halved new potatoes into a pan of boiling salted water. Simmer for 12–15 minutes until tender when pierced with a fork. Drain and set aside.
- Step 3: In a large saucepan, heat the olive oil over medium heat. Fry the sliced red and yellow peppers along with the julienned carrot for 8–10 minutes until softened.
- Step 4: Stir in the grated garlic, chilli flakes, and thyme leaves. Season with salt and pepper and cook for another minute to release the flavors.
- Step 5: Add the finely sliced hispi cabbage and 3 tablespoons of water to the pan. Cook for 2–3 minutes until the cabbage softens but still retains a slight crunch.
- Step 6: To serve, place the vegetable mixture on plates and top with the baked fish. Drizzle the lemony buttery juices from the roasting tray over the potatoes and sprinkle chopped parsley on top if using. Serve with lemon wedges for squeezing over the dish.
Tips & Variations
- Use sustainable white fish like cod, haddock, or pollock for the best flavor and environmental impact.
- For extra zest, add a splash of lemon juice to the vegetables just before serving.
- If you prefer less heat, reduce or omit the chilli flakes.
- Swap hispi cabbage for shredded savoy or green cabbage if unavailable.
- To save time, use baby potatoes that don’t require halving.
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. The vegetables reheat well and maintain their texture.
