Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Place 2 lbs peeled and quartered russet potatoes into a large pot, cover with cold water and 1/2 tsp salt, bring to a boil and cook for 15-18 minutes until tender.
  2. Step 2: While potatoes cook, heat 1 tbsp olive oil in a large skillet over medium-high heat. Add 1 diced medium yellow onion and 2 diced medium carrots, sauté for 5 minutes until softened. Add 3 minced garlic cloves and cook for 30 seconds until fragrant.
  3. Step 3: Add 1 lb ground beef to the skillet, breaking it up with a spoon. Cook for 6-8 minutes until browned and no longer pink.
  4. Step 4: Stir in 2 tbsp tomato paste and 1 tbsp all-purpose flour, cooking for 1 minute to remove raw flour taste. Gradually add 1 cup beef broth and 1 tbsp Worcestershire sauce, stirring constantly until mixture thickens, about 3 minutes.
  5. Step 5: Stir in 1 cup frozen peas, 1/2 tsp salt, and 1/4 tsp black pepper, then remove from heat.
  6. Step 6: Drain potatoes and return to pot. Add 4 tbsp butter, 1/2 cup whole milk, 1/2 tsp salt, and 1/4 tsp black pepper. Mash with a potato masher or electric mixer until smooth and fluffy.
  7. Step 7: Transfer beef mixture to a 9x9-inch baking dish and evenly spread garlic mashed potatoes on top.
  8. Step 8: Bake in the preheated oven for 20-25 minutes until the edges are bubbly and the potato topping is golden brown.
  9. Step 9: Let rest for 5 minutes before serving to allow flavors to meld.
