Method

  • step 1

    Heat the oven to 200C/180C fan/gas 4. Line a large, high-sided roasting tin with baking parchment, then arrange the potato and fennel slices in the tray, layering them in overlapping rows alternately until they cover the whole tin and doubling up the layers if you have leftover slices. Season with salt. Brush over the vegetable oil, then roast for 15 mins, or until the edges of the veg have started to crisp up and caramelise.

  • step 2

    Meanwhile, combine the garlic, palm or brown sugar, fish sauce, lime juice, coriander stalks and 75ml hot water in a small bowl.

  • step 3

    Lightly season the inside and outside of the fish with salt, then put the lemongrass inside the cavities. Brush the fish lightly with oil. Remove the veg from the oven and lay the fish on top. Pour a little of the sauce inside each cavity, then the rest over the skin. Cover with foil and bake for 15 mins until the fish is nearly cooked and the flesh flakes easily.

  • step 4

    Remove the foil for the final 10 mins of cooking. Heat the grill to high. Slide the fish under the hot grill briefly until the skin has browned and blistered. Scatter over the coriander leaves, spring onions, chilli and lime slices, then serve.

Recipe tip

While salmon is often served at Easter, mackerel is a cheaper option, mainly because it’s in season at this time – which means it’s also a sustainable option. This dish is also cooked in one tin, so will save on washing-up.

Fab recipe, I tone down the fish sauce and let the potatoes and fennel cook a little longer before the fish goes in. Very tasty, great with bass too!

question

Please could I double check that 75ml of fish sauce is correct,

Hi, thanks for your question. Yes 75ml is correct but you can reduce it to 2-3 tablespoons if you prefer a less strong and salty sauce. We hope this helps. Best wishes, BBC Good Food Team.
