Ingredients You’ll Need

For the filling: 1½ pounds ground beef or lamb, 1 tablespoon olive oil, 1 yellow onion (diced), 2 carrots (diced), 3 cloves garlic (minced), 2 tablespoons tomato paste, 2 tablespoons all-purpose flour, 1 cup beef broth, 1 tablespoon Worcestershire sauce, 1 teaspoon dried thyme, 1 cup frozen peas, and salt and pepper
For the potato topping: 2½ pounds Yukon Gold potatoes (peeled and cubed), 4 tablespoons butter, ½ cup warm milk, 1 teaspoon salt, and 1 cup shredded cheddar (optional)

How to Make Classic Shepherd’s Pie

Boil the potatoes in salted water for 15 to 20 minutes until very tender, then drain and mash with the butter, warm milk, and salt until smooth. Stir in half the cheddar if using.
Preheat the oven to 400°F (200°C). Heat the olive oil in a large skillet over medium-high heat and brown the beef for 6 to 8 minutes. Drain the excess fat.
Add the onion and carrots and cook for 5 minutes, then stir in the garlic and tomato paste and cook for 1 minute.
Sprinkle in the flour, then add the broth, Worcestershire, thyme, salt, and pepper and simmer for 8 to 10 minutes until thick. Stir in the peas.
Spread the filling in a 9×13-inch baking dish, then spoon the mashed potatoes over the top and spread to the edges. Drag a fork across the surface to create ridges and sprinkle with the remaining cheese.
Bake for 25 to 30 minutes until bubbly and golden on top, then rest for 10 minutes before serving.
