  • leftover Roast Lamb
  • 1 tbsp olive oil
  • 1 medium onion
  • 2 cloves garlic
  • 1 carton passata 500g
  • 1 tsp dried oregano
  • 1/2 tsp dried rosemary
  • 1 tsp mint sauce
  • salt and pepper to taste
  • 4 to 6 small to medium potatoes we used Maris Pipper in the recipe
  • 1 handful grated cheddar cheese


  • Preheat the oven to 180C.
  • Chop up the leftover roast lamb into cubes and put in a food processor.
  • Using the pulse chop the lamb to a mince consistency and set aside.
  • Finely chop a medium onion and crush the cloves of garlic.
  • In a saucepan add some olive oil and heat.
  • Add the onion and garlic to the olive oil and brown.
  • Once they start to brown add in the mince and stir to warm up and brown a little more.
  • Then add in the passata.
  • Stir until well combined and then add in the herbs and season with salt and pepper.
  • Leave to simmer for around 10 minutes whilst you slice the potatoes and grate the cheddar cheese.
  • With your meat sauce finished pour into an oven proof dish and add the potatoes over the top.
  • Drizzle a little olive oil over them and then sprinkle the cheddar over the top.
  • Place in the oven for 20 minutes until the potatoes are crisp and the cheese is bubbling.
  • Allow to cool for 3 to 5 minutes and then serve. It's great with some vegetables.
