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 baking tray with parchment paper
  • Pull out a medium frying pan, a medium bowl & a grater

Roast the potatoes & prep the tomato olive sauce

  • Dice the potatoes into 2cm chunks. Zest and quarter the lemon
  • Place the potatoes onto the lined baking tray, drizzle with 2 tsp oil and season with salt and pepper. Roast for 12-15 mins
  • Meanwhile, roughly chop the parsley. Thinly slice the olives and spring onions. Quarter the tomatoes
  • In the medium bowl, mix together the parsley, spring onion, tomatoes, olives and 1 tbsp oil. Set aside

Add the hake & green beans

  • Trim the green beans
  • After 12-15 mins, move the potatoes to one side of the tray, then add the hake and lemon wedges to the other side. Drizzle the hake with 1 tsp oil and sprinkle over the lemon zest. Add the green beans and drizzle with 1 tsp oil
  • Season with salt and pepper, then return the tray to the oven for a further 16 mins, until the fish is cooked through and the potatoes are golden

Finish the sauce

  • Finely chop or crush the garlic
  • Heat the medium frying pan with 1 tsp oil on medium heat. Once hot, add the garlic and tomato olive sauce and cook for 3-4 mins, until the tomatoes soften

Finish & plate up

  • Check your fish is cooked through; it should be steaming hot, opaque and separate easily with a fork
  • Serve the potatoes and green beans into bowls, with the tomatoes alongside. Lay the hake on top and spoon over the olive sauce. Garnish with the remaining roasted lemon wedges
