Cooking Instructions

The protein cooking time listed in this recipe has been updated.

As of December 2025, we’ve revised cooking times for all our proteins to reflect improved food safety guidance.

Check out the latest recommended times in our Cooking Guidelines.

Before you start

  • Preheat the oven to 240C / fan 220C / gas mark 9
  • Line a large baking tray with parchment paper
  • Pull out a small bowl

Roast the potatoes

  • Halve the potatoes, then add to the large baking tray. Toss with 1 tbsp oil, half the za'atar and a pinch of salt and pepper. Roast for 25-30 mins, until soft and golden

Prep the rest

  • Thinly slice the pepper. Trim the green beans. Halve the preserved lemon and discard the seeds, then roughly chop with the olives
  • In the small bowl, combine the sundried tomato paste, chopped preserved lemon and olives

Stuff & roast the sea bass

  • Open the sea bass fillets and spread the lemon and olive mixture over the flesh. Fold to close, then rub with 2 tsp oil and the remaining za'atar
  • When the potatoes have 16 mins remaining, transfer the sea bass to the baking tray. Place the green beans, sliced pepper and tomatoes alongside. Toss with 1 tsp oil and salt and pepper. Roast together for the final 16 mins, until golden and cooked through

Finish & plate up

  • Add the flaked almonds to the veg for the final 5 mins of roasting, until golden
  • Check your fish is cooked through; it should be steaming hot, opaque and separate easily with a fork
  • When everything's ready, add a squeeze of fresh lemon to the veg and toss to coat
  • Share the sea bass between plates, with the potatoes and roasted veg alongside. Garnish with the remaining fresh lemon, cut into wedges
