Instructions

1. Step 1: Preheat oven to 400°F. In a large skillet over medium heat, cook 1 lb ground beef with 1 diced medium onion and 2 diced medium carrots until beef is browned and vegetables softened, about 8 minutes. Drain excess fat.
2. Step 2: Stir in 2 tbsp tomato paste, 1 cup beef broth, 1 tbsp Worcestershire sauce, and 1 cup frozen peas. Simmer for 5 minutes until sauce thickens slightly, then season with 1 tsp salt and 1/2 tsp black pepper.
3. Step 3: Meanwhile, place 2 lbs peeled and chunked potatoes in a pot and cover with cold water. Add 4 whole garlic cloves, bring to a boil, and cook until potatoes are tender, about 15 minutes. Drain potatoes and garlic.
4. Step 4: Mash potatoes and garlic with 4 tbsp butter and 1/2 cup milk until smooth and creamy. Adjust salt to taste.
5. Step 5: Transfer meat mixture to a 9x9-inch baking dish and spread mashed potatoes evenly over the top. Use a fork to create ridges on the potato surface.
6. Step 6: Bake in the preheated 400°F oven for 20 minutes until the potato topping is golden and edges are bubbling. Let rest for 5 minutes before serving.
