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

  • Bring a large saucepan filled with salted water to a boil
  • Line a baking tray with silver foil
  • Pull out a large bowl, a sieve, a peeler & a grater

Boil the potatoes

  • Peel and roughly cut the potatoes into 3cm chunks, then add to the saucepan of boiling water. Simmer for 14-16 mins, until soft, then drain. Return to the pan and allow to cool

Finish the prep

  • Zest and halve the lemon. Thinly slice the onion. Halve the tomatoes. Thinly slice the chives. Roughly chop the olives. Thinly slice the gem lettuce
  • In the large bowl, combine the juice from half the lemon with half the onion and a pinch of salt. Set aside to pickle
  • Preheat the grill to high (240C)

Get grilling

  • Lay the sea bass, skin-side up, onto one side of the lined tray. Drizzle with 1 tsp olive oil, season with salt, then rub with the lemon zest and olives. Sprinkle over the remaining onion. Add the sugar snap peas to the other side of the tray and toss with 1 tsp olive oil and a pinch of salt
  • Grill for 10-11 mins, until golden and cooked through

Assemble the salad

  • Once cooked toss the yoghurt, mustard and chives though the potatoes and season with salt and pepper
  • When everything's ready, add the tomatoes, lettuce and sugar snap peas to the pickled onion bowl, along with 1 tsp olive oil. Toss and season with salt and pepper

Finish & plate up

  • Check your fish is cooked through; it should be steaming hot, opaque and separate easily with a fork
  • Share the sea bass between plates, with the salad and potatoes alongside. Garnish with the remaining lemon, cut into wedges
