Cottage pie combines a savory ground-beef filling with a mashed-potato topping. Beef distinguishes it from shepherd’s pie, which traditionally uses lamb. The filling should be thick before it goes into the dish; a thin gravy can bubble through the topping and make portions difficult to serve.
Ingredient notes
- Potatoes: Cut into similar chunks so they become tender together. Drain thoroughly before mashing to avoid a watery topping.
- Unsalted butter: Mix into the hot drained potatoes so it melts evenly; it also enriches the mash.
- Milk: Warm before adding gradually. Stop once the mash is spreadable rather than loose or runny.
- Olive oil: Use for browning the filling ingredients; drain excessive rendered beef fat before continuing if needed.
Tips for a dependable result
Cut potatoes into similar-sized pieces so they soften together. Drain thoroughly and let steam escape before mashing; watery potatoes make a loose topping. Use warm milk and mash gently rather than blending, which can make the potatoes gluey. Taste both filling and mash before assembly. Dollop the topping over several spots before spreading so it stays on top of the beef. Fork ridges increase the surface available for browning. A rimmed tray beneath the dish catches occasional bubbling gravy.

Ingredients
Method
- Heat oven to 400°F (200°C). Put potatoes in salted cold water, bring to a boil, and simmer 15 to 20 minutes until easily pierced. Drain well, let steam dry, then mash with butter, warm milk, and 1/4 teaspoon salt.
- Meanwhile warm oil in a large skillet. Brown beef over medium-high heat, breaking it up, for 6 to 8 minutes. Add onion and carrots and cook 7 minutes. Drain excess fat if needed.
- Stir in garlic and tomato paste for 1 minute, then flour for 1 minute. Add broth, Worcestershire, thyme, remaining 1/2 teaspoon salt, and pepper. Simmer 10 minutes until the vegetables are tender and the gravy is thick. Stir in peas.
- Transfer filling to a 2-quart baking dish. Spoon mashed potatoes over the top in small dollops, spread to the edges, and roughen the surface with a fork.
- Bake 25 to 30 minutes until bubbling and lightly browned, with the center reaching 165°F (74°C). Rest 10 minutes before dividing into 6 servings.

Storage and make-ahead notes
Refrigerate within 2 hours and use within 3 to 4 days. Reheat covered to 165°F (74°C). Freeze cooled portions up to 2 months. The oven time applies to a freshly assembled pie; a refrigerated pie takes longer to heat through.
For general storage and reheating guidance, see the USDA guidance on leftovers and food safety.
