Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Boil 3 large peeled and quartered russet potatoes in salted water for 15 minutes until tender.
  2. Step 2: While potatoes cook, heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 1 medium diced onion and 2 diced medium carrots, sauté for 5 minutes until softened.
  3. Step 3: Add 1 lb ground beef to the skillet, breaking it apart with a spoon. Cook for 6-7 minutes until browned and no longer pink.
  4. Step 4: Stir in 2 tbsp tomato paste, 1 tbsp Worcestershire sauce, and 2 tbsp all-purpose flour. Cook for 1 minute to remove raw flour taste.
  5. Step 5: Pour in 1 cup beef broth, add 1 cup frozen peas, and simmer for 5 minutes until mixture thickens. Season with 1 tsp salt and 1/2 tsp black pepper.
  6. Step 6: Drain potatoes and mash with 4 tbsp butter, 1/2 cup milk, and 3 minced garlic cloves until smooth and creamy.
  7. Step 7: Transfer beef mixture to a 9x9-inch baking dish. Spread mashed potatoes evenly on top, smoothing with a spatula.
  8. Step 8: Bake uncovered for 20 minutes until the edges bubble and potatoes begin to brown. Let rest for 5 minutes before serving.

Can I substitute ingredients in Baked Shepherd’s Pie with Garlic Mashed Potatoes?
