Ingredients:

  • 2 kg (2.6 lbs) Starchy Potatoes (e.g., Russet, King Edward, or Maris Piper), peeled and quartered
  • 120 ml (½ cup) Whole Milk, warmed
  • 115 g (8 Tbsp/1 stick) Unsalted Butter, cut into cubes
  • 1 large Egg Yolk (optional, for richness and colour)
  • 1 tsp Coarse Sea Salt
  • ½ tsp Freshly Ground Black Pepper
  • 50 g (½ cup) Mature Cheddar Cheese, grated (for topping)
  • 1 Tbsp Olive Oil or Vegetable Oil
  • 1 large (150 g) Yellow Onion, finely diced
  • 2 medium (150 g) Carrots, peeled and finely diced
  • 2 sticks (75 g) Celery, finely diced
  • 1 kg (2.2 lbs) Lean Minced Lamb
  • 1 Tbsp All-Purpose Flour (Plain Flour)
  • 1 Tbsp Tomato Purée (Tomato Paste)
  • 1 Tbsp Worcestershire Sauce
  • 250 ml (1 cup) Dry Red Wine or Dark Stout (Optional)
  • 500 ml (2 cups) Lamb or Beef Stock (High quality, low sodium)
  • 1 Tbsp Fresh Rosemary, finely chopped
  • 1 Tbsp Fresh Thyme Leaves
  • 1 Bay Leaf
  • Salt and Black Pepper, to taste

Instructions:

  1. Prepare the Creamy Mash: Place peeled and quartered potatoes in a large saucepan. Cover with cold, salted water. Bring to a boil, then reduce heat and simmer until fork-tender (15-20 minutes).
  2. Drain and Dry: Thoroughly drain the potatoes. Return them to the hot pan for one minute over low heat, shaking occasionally, to steam off excess moisture. This is key for fluffy mash.
  3. Mash and Enrich: Pass the potatoes through a ricer or mash thoroughly. Incorporate the butter and seasoning. Gradually beat in the warmed milk until the mash is smooth and creamy, but stiff enough to hold its shape. Stir in the optional egg yolk last. Set aside.
  4. Sauté Aromatics: Heat oil in a large pan over medium-high heat. Add the diced onion, carrot, and celery. Sauté for 6-8 minutes until the vegetables are softened and the onions are translucent. Remove the vegetables and set aside.
  5. Brown the Lamb: Add the minced lamb to the pan, breaking it up with a spoon. Cook until thoroughly browned. Drain off any excess fat (a crucial step to avoid a greasy pie).
  6. Build Flavour: Return the sautéed vegetables to the pan. Stir in the flour and tomato purée, cooking for 1 minute. Add the Worcestershire sauce, chopped herbs, and bay leaf.
  7. Create the Gravy (Deglaze): Pour in the red wine or stout (if using). Bring to a boil and reduce the liquid by half, scraping up any browned bits from the bottom of the pan.
  8. Simmer: Pour in the stock. Bring the mixture to a gentle boil, then reduce the heat to low. Simmer uncovered for 20 minutes, allowing the gravy to thicken and the flavours to meld. The gravy should be thick and clinging to the meat, not watery.
  9. Seasoning Check: Remove the bay leaf. Taste the filling and adjust salt and pepper. Preheat the oven to 200°C (400°F).
  10. Assemble the Dish: Transfer the lamb filling into the prepared 9x13 inch baking dish. Ensure the filling is spread evenly.
  11. Top with Mash: Spoon the potato mash over the filling. Spread it evenly, or pipe it attractively. Create ridges with a fork to maximise the crispy surface area.
  12. Bake: Sprinkle the grated Cheddar lightly over the mash. Bake for 25–30 minutes, or until the filling is bubbling up around the edges and the potato topping is deeply golden brown.
  13. Rest: Allow the Shepherd’s Pie to rest for 10 minutes after removing it from the oven before serving. This allows the gravy to settle and makes serving cleaner.
