Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Boil 2 lbs peeled and cubed potatoes in salted water for 15-20 minutes until very tender.
  2. Step 2: While potatoes cook, heat 1 tbsp butter in a large skillet over medium heat. Add 1 medium diced carrot and 1 medium finely chopped onion, sauté for 5 minutes until softened.
  3. Step 3: Add 1 lb ground beef to the skillet, breaking it apart. Cook until browned, about 6-8 minutes, then stir in 2 tbsp tomato paste and 1 tbsp Worcestershire sauce.
  4. Step 4: Sprinkle 2 tbsp all-purpose flour over the beef mixture and stir for 1 minute. Pour in 1 cup beef broth, stir, and simmer for 5 minutes until thickened. Add 1 cup frozen peas, 1 tsp salt, and 1/2 tsp black pepper, cook for another 2 minutes.
  5. Step 5: Drain potatoes and mash with 4 tbsp butter, 1/2 cup milk, and 3 minced garlic cloves until creamy and smooth.
  6. Step 6: Transfer the beef and vegetable mixture into a 9x9-inch baking dish, spreading evenly. Top with the mashed potatoes, smoothing the surface.
  7. Step 7: Bake in preheated oven for 20-25 minutes until the edges bubble and the potato topping is lightly golden. Let rest for 5 minutes before serving.
