Preparation Steps

• Preheat oven to 375°F (190°C).
• In a large skillet, brown the ground lamb over medium-high heat. Drain off any excess grease.
• Add the chopped onion and minced garlic to the skillet and cook until softened, about 5 minutes.
• Stir in the tomato paste and Worcestershire sauce. Cook for 1 minute more.
• Pour in the beef broth and bring to a simmer. Add the frozen peas and carrots. Season with salt and pepper to taste. Simmer for 10 minutes, or until the sauce has thickened slightly.
• While the meat sauce is simmering, prepare the mashed potatoes. Boil the potatoes until tender. Drain and mash with milk, butter, salt, and pepper until smooth and creamy.
• Pour the meat sauce into a baking dish. Spread the mashed potatoes evenly over the top.
• Bake in the preheated oven for 20-25 minutes, or until the mashed potatoes are golden brown and the sauce is bubbly.
• Let cool slightly before serving.
