Shepherd’s pie is a staple of British and Irish kitchens, and it starts with ground lamb simmered with carrots, celery, and a small pour of red wine, all buried under a thick blanket of mashed potato and baked until the top turns golden and crackled. This is the dinner I want when the weather turns cold, when the week has been long, or when you just need something that feels like home. Lamb or beef, you ask? Lamb makes it a shepherd’s pie and beef makes it a cottage pie, and the method is the same either way.
This version uses an egg yolk in the mashed potato topping, which helps it brown more deeply in the oven and gives it enough structure to hold above the filling without sinking. Start spreading the mash from the edges inward to seal in the gravy, then drag a fork across the surface to create ridges that crisp up during baking. The whole thing can be assembled a day ahead and refrigerated, making it a strong choice for feeding a group on a weekend. Serve it with a simple green salad and you have a complete meal that nobody will complain about.
How to Make Shepherd’s Pie
Build the Filling Properly
Brown the ground lamb over medium-high heat until it has real color, not just gray. This takes 8 to 10 minutes and you should not stir constantly, let it sit and develop a crust. Drain off the excess fat but leave about a tablespoon in the pan for flavor.
Tomato paste goes in next, cooked for a minute to take the raw edge off, followed by flour to thicken. Then beef stock and red wine. The Worcestershire sauce and thyme go in last. Simmer everything for 20 to 25 minutes until the liquid has reduced and the filling is thick enough to hold its shape under the potato.
Get the Mash Right
The potato topping needs to be rich and smooth. Boil Yukon Golds until they fall apart when pierced, then rice or mash them with butter, warm cream, and an egg yolk. The egg yolk helps the mash brown deeply in the oven and gives the topping enough structure that it does not sink into the filling.
Spread the mash over the filling, starting at the edges to create a seal, then work toward the center. Use a fork to rough up the surface, those ridges and peaks are what turn golden and crispy under the heat.
Bake Until the Top is Properly Golden
Bake at 400F (200C) for 25 to 30 minutes until the potato is golden brown and the filling is bubbling up around the edges. If the top is not browning enough, run it under the broiler for the last 2 to 3 minutes. Watch it closely, it goes from golden to burned fast.
Let it rest for 10 minutes before serving. Cutting into it immediately means the filling runs everywhere.

Shepherd’s Pie with Red Wine Gravy and Egg Yolk Mash
- Total Time: 90 minutes
- Yield: 6 servings
Description
Shepherd’s pie is a cornerstone of British and Irish home cooking: ground lamb in a red wine gravy, covered with a thick layer of mashed potato and baked until the top is golden and the filling bubbles at the edges. It began as a way to use up leftover Sunday roast.
Ingredients
- For the filling:
- 2 tablespoons olive oil
- 1 large yellow onion, diced
- 2 medium carrots, peeled and diced
- 2 stalks celery, diced
- 3 cloves garlic, minced
- 1 1/2 pounds ground lamb
- 2 tablespoons tomato paste
- 1 tablespoon all-purpose flour
- 1 cup beef or lamb stock
- 1/2 cup dry red wine
- 2 teaspoons Worcestershire sauce
- 1 teaspoon fresh rosemary, finely chopped
- 1 teaspoon fresh thyme leaves
- 1/2 cup frozen peas
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- For the mashed potato topping:
- 2 1/2 pounds Yukon Gold potatoes, peeled and cut into chunks
- 4 tablespoons unsalted butter
- 1/2 cup warm whole milk
- 1 large egg yolk
- 1 teaspoon kosher salt
- 1/4 teaspoon white pepper
Instructions
- Heat the olive oil in a large oven-safe skillet or Dutch oven over medium-high heat. Add the onion, carrots, and celery. Cook for 6-7 minutes until softened. Add the garlic and cook 30 seconds.
- Add the ground lamb. Break it up with a spoon and cook for 8-10 minutes until browned. Drain off excess fat, leaving about 1 tablespoon in the pan.
- Stir in the tomato paste and flour. Cook for 1 minute. Add the red wine and scrape up any browned bits from the bottom of the pan. Add the stock, Worcestershire sauce, rosemary, thyme, salt, and pepper.
- Bring to a simmer and cook for 15-20 minutes, stirring occasionally, until the filling is thick and saucy. Stir in the frozen peas. Transfer to a 9×13-inch baking dish if not using an oven-safe skillet.
- While the filling simmers, boil the potatoes in salted water until very tender, about 15-18 minutes. Drain well and return to the pot over low heat for 1 minute to dry out excess moisture.
- Mash the potatoes with the butter and warm milk until smooth. Beat in the egg yolk, salt, and white pepper. The mash should be thick enough to hold its shape — do not make it too thin.
- Preheat the oven to 400°F. Spread the mashed potatoes over the lamb filling, starting from the edges and working inward to create a seal. Use a fork to create ridges across the top — these peaks will turn golden and crisp.
- Bake for 25-30 minutes until the top is golden brown and the filling is bubbling around the edges. Let rest for 10 minutes before serving.
Notes
- True shepherd’s pie uses lamb. If you use beef, the dish is properly called cottage pie. Both are made the same way.
- The egg yolk in the mash helps it brown more deeply and gives the topping structure so it holds above the filling rather than sinking in.
- Starting the potato layer at the edges creates a seal that prevents the filling from bubbling over and making a mess in the oven.

Frequently Asked Questions
What is the difference between shepherd’s pie and cottage pie?
Shepherd’s pie uses ground lamb, cottage pie uses ground beef. The preparation is otherwise identical. If you are using beef, the dish is properly called cottage pie. Both are traditional British and Irish.
Can I make shepherd’s pie ahead of time?
Assemble the full dish, cover tightly, and refrigerate for up to 2 days before baking. Add 10 to 15 extra minutes to the bake time since it is starting cold. You can also freeze the assembled pie for up to 2 months, thaw overnight in the refrigerator before baking.
Why add an egg yolk to the mashed potato topping?
The egg yolk helps the potato brown more deeply in the oven and gives the topping enough structure to hold its shape instead of sinking into the filling. Without it, the mash tends to stay pale and soft on top.
