Before you start

  • Preheat the oven to 240C / fan 220C / gas 9 / air fryer 190C
  • Line a baking tray with parchment paper
  • Pull out a sieve, a measuring jug & a large frying pan and a medium frying pan

Golden potatoes & pickle the shallot

  • Cut the potatoes into wedges
  • Place onto the lined baking tray and toss with 1/2 tbsp oil, a pinch of salt and pepper
  • Roast for 25-30 mins / air fryer 20-25 mins until soft and golden, turning halfway
  • Thinly slice the shallot. Combine the juice from half of the lemon with a pinch of salt and pepper in the small bowl, then add half of the shallot and toss to coat. Set aside to pickle

Cook the fine green beans

  • Pick the tarragon from the stalks and finely chop. Finely slice the shallot and garlic. Trim the green beans
  • Heat the medium frying pan with 1 tsp oil on medium-high heat. Once hot, add the green beans and cook for 3-4 mins, until starting to char. Add the peas and 1 tbsp water (1/2 tbsp for 1 person) and steam for 2-3 mins, until softened. Season with salt and pepper

Cook the fish

  • Heat the large frying pan with 1/2 tbsp oil on medium heat
  • Season the fish with salt and pepper. Once the pan is hot, place the fish skin-side down and fry for 5 mins. Flip, and fry for a further 4 mins, until cooked through
  • Remove and set aside

Get your simmer on

  • Reheat the large frying pan with 1/2 tbsp oil on medium-high heat. Once hot, add the garlic and remaining shallot and cook for 5 mins, until softened. Season with salt and pepper
  • Add the tarragon, soft cheese, and 50ml hot water (25ml for 1 person)
  • Stir well and simmer for 3-5 mins until thickened. Squeeze in the juice from half the lemon then season with salt and pepper

Plate up

  • Check your fish is cooked through; it should be steaming hot, opaque and separate easily with a fork
  • Serve the sea bass with the potato wedges and fine green beans. Pour the lemon and tarragon sauce over the fish. Top the greens with the pickled shallot
