Ingredients
- 1 lb ground beef
- 1 medium, diced onion
- 2 medium, diced carrots
- 1 cup frozen peas
- 2 tbsp tomato paste
- 1 cup beef broth
- 1 tbsp Worcestershire sauce
- 2 lbs, peeled and cut into chunks potatoes
- 4 whole garlic cloves
- 4 tbsp butter
- 1/2 cup milk
- 1 tsp salt
- 1/2 tsp black pepper
Instructions
- 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.
- 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.
- 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.
- Step 4: Mash potatoes and garlic with 4 tbsp butter and 1/2 cup milk until smooth and creamy. Adjust salt to taste.
- 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.
- 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.
