Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Place 2 lb peeled and quartered potatoes in a large pot of salted water and bring to a boil. Cook for 15-20 minutes until fork-tender, then drain and mash with 4 tbsp butter, 1/2 cup milk, 1 tsp salt, and 1/2 tsp black pepper until creamy.
  2. Step 2: Meanwhile, heat 2 tbsp olive oil in a large skillet over medium-high heat. Add 1 diced onion, 2 diced carrots, 1 diced parsnip, and 2 diced celery stalks. Sauté for 5 minutes until softened. Add 3 minced garlic cloves and cook for 1 minute until fragrant.
  3. Step 3: Add 1 lb ground beef to the skillet, breaking it up with a spoon. Cook until browned and no longer pink, about 6-8 minutes. Stir in 2 tbsp tomato paste and cook for 2 minutes.
  4. Step 4: Pour in 1 cup beef broth, add 1 cup frozen peas, and simmer for 5 minutes until the mixture thickens slightly. Adjust seasoning with salt and pepper.
  5. Step 5: Transfer the beef and vegetable mixture into a 9x13-inch baking dish. Spread the mashed potatoes evenly over the top with a spatula.
  6. Step 6: Bake uncovered for 20-25 minutes until the potato topping is golden and the filling is bubbling. Let rest for 5 minutes before serving.
