Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F (190°C). Boil 2 lbs peeled and chopped potatoes in salted water (1 tsp salt) for 15-20 minutes until tender. Drain and mash with 4 tbsp butter, 1/2 cup milk, 1 tsp salt, and 1/2 tsp black pepper until smooth and creamy.
  2. Step 2: Meanwhile, heat 2 tbsp olive oil in a large skillet over medium heat. Add 1 finely chopped onion, 2 diced carrots, and 1 diced parsnip, cooking for 5 minutes until softened.
  3. Step 3: Add 3 minced garlic cloves and sauté for 1 minute until fragrant. Add 1 lb minced lamb and cook, breaking up with a spoon, until browned and cooked through, about 6-8 minutes.
  4. Step 4: Stir in 2 tbsp tomato paste, 1 cup beef stock, 1 tbsp Worcestershire sauce, 1/2 cup frozen peas, 1 tsp salt, and 1/2 tsp black pepper. Simmer for 10 minutes until the sauce thickens and coats the vegetables and meat.
  5. Step 5: Transfer the lamb mixture to a baking dish and spread evenly. Top with the creamy mashed potatoes, smoothing the surface. Bake uncovered for 25-30 minutes until the potato topping is golden brown and the filling is bubbling.
