Instructions

1. Step 1: Preheat oven to 400°F. Boil 2 lbs peeled and quartered potatoes in salted water for 15-20 minutes until tender. Drain and mash with 4 tbsp butter, 1/2 cup milk, 1 tsp sea 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 diced onion and 2 diced carrots, sauté for 5 minutes until softened.
3. Step 3: Add 1 lb ground lamb to the skillet and cook, breaking up with a spoon, until browned and cooked through, about 7 minutes.
4. Step 4: Stir in 2 tbsp tomato paste, 1 cup beef broth, 1 tbsp Worcestershire sauce, and 1 cup frozen peas. Simmer for 10 minutes until the sauce thickens and coats the meat and vegetables.
5. Step 5: Transfer the lamb mixture to a baking dish and spread the mashed potatoes evenly on top. Use a fork to create texture on the potato surface.
6. Step 6: Bake in the oven for 20-25 minutes until the top is golden brown and edges are bubbling. Let rest for 5 minutes before serving.
