Instructions

1. Step 1: Preheat oven to 375°F. Heat 2 tablespoons olive oil in a large oven-safe skillet over medium-high heat. Add 1.5 pounds ground beef and cook until browned, breaking into small pieces, about 5 minutes; drain excess fat.
2. Step 2: Add 2 medium diced carrots, 1 medium diced parsnip, 1 medium chopped onion, and 3 minced garlic cloves to the skillet. Cook for 5 minutes until vegetables soften. Stir in 1 cup beef broth, 1 tablespoon tomato paste, 1 teaspoon dried thyme, 1/2 teaspoon dried rosemary, and 1/4 cup fresh parsley. Simmer for 10 minutes until liquid reduces slightly.
3. Step 3: Stir 2 tablespoons all-purpose flour into the mixture until thickened, then season with salt and pepper to taste. Transfer filling to a 9-inch pie dish.
4. Step 4: Boil 1.5 pounds diced potatoes in salted water for 15-20 minutes until fork-tender. Drain, return to pot, and add 1/2 cup milk and 4 tablespoons unsalted butter. Mash until smooth. Season with salt and pepper.
5. Step 5: Spread mashed potatoes evenly over filling, then sprinkle 1/2 cup shredded cheddar cheese on top. Bake for 25-30 minutes until golden and bubbly.
