Ingredients

Instructions

  1. Step 1: Preheat the oven to 400°F (200°C). Boil 700 g peeled and quartered potatoes in salted water for 15-20 minutes until tender.
  2. Step 2: While potatoes cook, heat 2 tbsp olive oil in a large skillet over medium-high heat. Add 1 large finely chopped onion, 2 diced carrots, and 2 diced celery stalks. Sauté for 5 minutes until softened.
  3. Step 3: Add 2 minced garlic cloves and 500 g ground lamb to the skillet. Cook, breaking up the meat, for 7-8 minutes until browned.
  4. Step 4: Stir in 2 tbsp tomato paste, 300 ml beef stock, and 1 tbsp Worcestershire sauce. Simmer for 15 minutes until sauce thickens. Add 100 g frozen peas and cook for 2 more minutes. Season with 1 tsp salt and 1/2 tsp black pepper.
  5. Step 5: Drain potatoes and mash with 50 g butter and 100 ml milk until smooth and creamy.
  6. Step 6: Transfer the lamb mixture to a baking dish, spread the mashed potatoes evenly on top, and smooth with a spatula. Bake for 20 minutes until the potato topping is golden and edges are bubbling.
