Ingredients

Serves

  • 1 onion
  • 2 carrots
  • 2 celery sticks
  • 2 garlic cloves
  • 20g butter
  • 200g lean steak mince
  • 1 tablespoon plain flour (15g)
  • ½ tablespoon tomato puree (7g)
  • ½ reduced salt chicken stock cube 
  • 250ml boiling water
  • 1 tablespoon Worcestershire sauce (15g)
  • 100g frozen peas
  • 300g floury potatoes (Rooster or Maris Piper)
  • 25ml low fat milk (1.5% fat)
  • 50g sugar snap peas
  • salt (optional) and freshly ground black pepper

Method

  1. Cut the onion in half and peel off the skin, then finely chop. Peel the carrots and dice with the celery. Peel the garlic and use a garlic crusher or grate on the fine side of a box grater.
  2. Heat a frying pan over a medium heat. Add half of the butter and once it is melted tip in the onion, carrots, celery and garlic, stirring to combine. Cook for about 5 minutes until softened, stirring occasionally with a wooden spoon.
  3. Add the steak mince to the pan and cook for another 3-4 minutes or until browned, stirring occasionally and breaking up any lumps with a wooden spoon. Stir in the flour and cook for 1 minute, stirring. Then stir in the tomato puree and allow to cook for a further minute. 
  4. Dissolve the chicken stock cube in the boiling water and pour into the mince mixture with the Worcestershire sauce, stirring to combine. Bring to a simmer and then cook for 10 minutes until thickened, stirring occasionally. Stir in the frozen peas and place in a small ovenproof dish. Set aside to allow a skin to form. This will make it easier to spread the potatoes in an even layer on top.
  5. Preheat the oven to 180C / 350F / gas mark 4. Peel and dice the potatoes. Steam the potatoes for 10-12 minutes, or until tender, with a pinch of salt (optional). To check, piece one with the tip of a sharp knife and you should feel no resistance.
  6. Tip into a bowl and mash with a potato masher until smooth. Season with plenty of freshly ground black pepper, then beat in the rest of the butter with the milk. Spoon the mash on top of the mince, starting with dollops around the edges and finishing with the middle.
  7. Spread around with a table knife until you have a nice even layer and then bake for 30-40 minutes until piping hot and golden brown. 
  8. About 5 minutes before the pie is due to come out of the oven, steam the sugar snap peas for 1-2 minutes until just tender. Drain and arrange on plates with the Shepherd's pie to serve.
