Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Boil 2 lbs peeled and cubed potatoes in salted water (1 tsp salt) for 15-20 minutes until tender. Drain and mash with 2 tbsp butter and 1/2 cup milk. Season with 1/2 tsp salt and 1/2 tsp black pepper. Set aside.
  2. Step 2: While potatoes cook, heat 2 tbsp olive oil in a large skillet over medium heat. Add 1 diced onion, 1 large diced carrot, and 1 medium diced parsnip. Sauté for 5 minutes until softened.
  3. Step 3: Add 2 minced garlic cloves and 1 lb ground lamb to the vegetables. Cook for 6-8 minutes, breaking up the meat until browned and fragrant.
  4. Step 4: Stir in 2 tbsp tomato paste, 1 cup beef broth, 1/2 cup frozen peas, 1 tsp salt, and 1/2 tsp black pepper. Simmer uncovered for 10 minutes until thickened.
  5. Step 5: Transfer the lamb mixture to a 9x9 inch baking dish. Spread the mashed potatoes evenly over the top and dot with remaining 2 tbsp butter.
  6. Step 6: Bake for 25 minutes until the potato topping is golden and edges bubbling. Let rest 5 minutes before serving.
