Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Boil 2 lbs peeled and quartered russet potatoes in salted water with 1/2 tsp salt until fork-tender, about 15 minutes.
  2. Step 2: While potatoes cook, heat 1 tbsp olive oil in a large skillet over medium heat. Add 1 diced medium onion and 1 diced medium carrot; sauté for 5 minutes until softened.
  3. Step 3: Add 1 lb ground beef to the skillet, breaking it up with a spoon; cook for 6-7 minutes until browned and no longer pink.
  4. Step 4: Stir in 2 tbsp tomato paste, 2 tbsp all-purpose flour, and cook for 1 minute to remove raw flour taste.
  5. Step 5: Gradually add 1 cup beef broth and 1 tbsp Worcestershire sauce, stirring until the sauce thickens and coats the meat, about 3-4 minutes.
  6. Step 6: Mix in 1 cup frozen peas and season the filling with 1/2 tsp black pepper and remaining 1/2 tsp salt; cook for 2 more minutes, then remove from heat.
  7. Step 7: Drain potatoes and mash with 4 tbsp butter, 1/2 cup milk, 1 tsp fresh thyme leaves, and 1/2 tsp black pepper until creamy and smooth.
  8. Step 8: Transfer the beef mixture to a 9x9-inch baking dish, spread mashed potatoes evenly over the top, using a fork to create texture.
  9. Step 9: Bake uncovered for 20-25 minutes until the potato topping is golden and edges are bubbling hot.
  10. Step 10: Let rest for 5 minutes before serving.
