Before you start

  • Line a baking tray with foil
  • Bring a large saucepan filled with salted water to a boil
  • Boil a half-full kettle
  • Pull out a medium frying pan, a medium ovenproof dish, a grater, measuring jug & a masher

Time to prep

  • Dice the carrot into 1cm chunks (make it kid friendly: leave the carrots out of the mash and serve as crunchy crudités on the side). Dice the potatoes into 2cm chunks (peel optional)
  • Add both to the saucepan of boiling water and simmer for 15-18 mins, until soft, then drain and add back to the pan
  • Meanwhile, slice the leek into 1/2cm half-moons. Cut the broccoli into small florets. Finely grate the cheese
  • Dissolve the cornflour in the jug with 50ml cold water, then add the stock powder and top up with 200ml boiling water

Make the filling

  • Heat the medium frying pan with 1 tsp oil on medium heat. Once hot, add the leek and cook for 5-6 mins, until softened
  • Increase the heat to medium-high, then stir in the stock mixture and mustard and bring to a boil
  • Drain the prawns, then add to the pan and simmer for 7 mins, stirring frequently, until the prawns are cooked through and the sauce is thick. Check your prawns are cooked through; they should be opaque, firm and steaming hot
  • Once cooked, return the carrot and potato to the pan and mash with 2 tsp oil, salt and pepper

Build the pie & grill

  • Turn the grill to high (240C)
  • Remove the prawn pan from the heat, then stir in the soft cheese and half the cheddar cheese. Season to taste
  • Transfer the pie filling to the medium ovenproof dish. Top with the mash and spread evenly
  • Use fork to scrape lines onto the mash then sprinkle with the remaining cheddar cheese
  • Add the broccoli on one side of the foil lined tray. Add the pie to the other. Grill the pie & broccoli for 8-10 mins, until golden (or boil the broccoli for 3-4 mins instead)

Plate up

  • Leave the pie to stand for 2-3 mins then serve onto plates, with the broccoli alongside
