Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Place 2 lbs peeled and quartered russet potatoes in a large pot of salted water and bring to a boil. Cook for 15-20 minutes until tender.
  2. Step 2: While potatoes cook, heat 2 tbsp unsalted butter in a large skillet over medium-high heat. Add 1 medium diced yellow onion and 2 diced medium carrots, sauté for 5 minutes until softened.
  3. Step 3: Add 1 lb ground beef to the skillet with vegetables, breaking it apart with a wooden spoon. Cook for 6-7 minutes until browned and no longer pink.
  4. Step 4: Stir in 2 tbsp tomato paste, 1 cup frozen peas, 1 tbsp Worcestershire sauce, 1 cup beef broth, 1 tsp salt (divided), and 1/4 tsp black pepper. Simmer over medium heat for 8 minutes until sauce thickens, stirring occasionally.
  5. Step 5: Drain potatoes and return to pot. Add 2 tbsp unsalted butter, 1/2 cup whole milk, 3 minced garlic cloves, 1/2 tsp salt, and 1/4 tsp black pepper. Mash until creamy and smooth.
  6. Step 6: Transfer beef mixture to a 9x9-inch baking dish, spreading evenly. Spoon mashed potatoes over the beef layer and smooth the top.
  7. Step 7: Dot the top with remaining 2 tbsp butter. Bake for 20 minutes until the edges are bubbling and the potato topping is lightly golden.
