  • 300g red-skinned potatoes, thinly sliced into rounds
  • 1 red pepper, cut into strips
  • 2 tbsp extra virgin olive oil
  • 1 rosemary sprig, leaves removed and very finely chopped



    Rosemary's intense, fragrant aroma has traditionally been paired with lamb, chicken and game…

  • 2 sea bass fillets
  • 25g pitted black olive, halved
  • ½ lemon, sliced thinly into rounds



    Oval in shape, with a pronouced bulge on one end, lemons are one of the most versatile fruits…

  • handful basil leaves


  1. Heat oven to 180C/160C fan/gas 4. Arrange the potato and pepper slices on a large non-stick baking tray. Drizzle over 1 tbsp oil and scatter with the rosemary, a pinch of salt and a good grinding of pepper. Toss everything together well and roast for 25 mins, turning over halfway through, until the potatoes are golden and crisp at the edges.

  2. Arrange the fish fillets on top and scatter over the olives. Place a couple of lemon slices on top of the fish and drizzle with the remaining oil. Roast for further 7-8 mins until the fish is cooked through. Serve scattered with basil leaves.

This was really good, I like seabass fillets but didn't know how to cook them and this method is perfect, next time I would add courgette as others have done. I did give the sliced potatoes longer about 40 mins.

Cooks the fish beautifully. I used sweet potatoes and added cherry tomatoes. Used fresh rosemary which smelt amazing when cooking but lovely mild flavour.

Very tasty, added sliced courgette to the tray as well, lovely way to serve fish

I used courgette instead of potato, used red and orange peppers and doubled up on seabass fillets as they were small! Will be doing this one again :)

We always enjoy this. I agree that courgette works really well and I usually use red, orange and yellow peppers. I've also used different fish fillets successfully. Tonight we're having trout fillets topped with nasturtium leaves and flowers instead of basil.

Yum. I add a sliced courgette or whole baby courgettes . I leave out the potatoes but serve with rice. My 6 year old adores this

Gorgeous, we have this at least once a week. I cook the potatoes on a higher temp than the recipe states before turning down to add peppers a little later.

This was delicious with a very delicate flavour. The olives really compliment this dish.
