This classic Shepherd’s Pie is made with seasoned ground lamb, carrots, onions, peas, and corn in a rich gravy, then topped with creamy mashed potatoes and baked until golden brown. It can also be assembled ahead of time and baked when you’re ready to serve.

Traditional Shepherd’s Pie is made with ground lamb, while Cottage Pie is made with ground beef. This version uses lamb, along with Worcestershire sauce, tomato paste, rosemary, and thyme for a savory filling.

Ingredient Notes & Substitutions

Ground Lamb: Lamb is what traditionally distinguishes Shepherd’s Pie from Cottage Pie. Ground beef can be used instead, but the dish would technically be Cottage Pie.

Yukon Gold Potatoes: Their naturally buttery texture makes smooth mashed potatoes that brown well in the oven. Russet potatoes also work well.

Onion, Carrots & Garlic: These add flavor and texture to the lamb filling without making it too heavy.

Tomato Paste & Worcestershire Sauce: Both add depth to the gravy and balance the richness of the lamb.

Beef Broth & Flour: Flour thickens the broth into a gravy that holds the filling together without making it dry.

Peas & Corn: Use ½ cup of each. Thaw before adding to the filling.

Step-by-Step Instructions

1. Make the Mashed Potatoes

1. Place the cubed potatoes in a large pot and cover with cold water. Add 1 teaspoon salt.
2. Bring to a boil and cook for 15–20 minutes, until fork-tender.
3. Drain well and return the potatoes to the warm pot for about 1 minute to remove excess moisture.
4. Mash with butter, warm cream, garlic powder, salt, and pepper until smooth. Set aside.

2. Cook the Lamb Filling

1. Heat olive oil in a large skillet over medium-high heat. Add the ground lamb, season with salt and pepper, and cook for 6–8 minutes, breaking it up as it browns.
2. Drain excess fat if needed, leaving about 1 tablespoon in the pan.
3. Add the onion and carrots. Cook for 4–5 minutes, until they begin to soften.
4. Stir in the garlic, tomato paste, and flour. Cook for 1 minute.
5. Slowly add the beef broth and Worcestershire sauce, scraping up any browned bits from the bottom of the pan.
6. Add the rosemary and thyme. Reduce the heat to medium-low and simmer for 8–10 minutes, until the gravy thickens.
7. Stir in the thawed peas and corn. Taste and adjust the salt and pepper.

3. Assemble & Bake

1. Preheat the oven to 400°F (200°C).
2. Transfer the lamb filling to a 9×13-inch baking dish.
3. Spread the mashed potatoes evenly over the filling, taking them all the way to the edges.
4. Use a fork to make shallow ridges across the potatoes. Sprinkle the cheddar cheese over the top if using.
5. Bake for 25–30 minutes, until the filling is bubbling and the potatoes are golden brown.
6. Let the Shepherd’s Pie rest for 10–15 minutes before serving. Garnish with fresh parsley if desired.

Tips for the Best Shepherd’s Pie

• Dry the potatoes well: Returning the drained potatoes to the warm pot for a minute helps prevent watery mashed potatoes.
• Don’t over-mash: Mash only until smooth. Overworking the potatoes can make them gummy.
• Spread the potatoes to the edges: This helps keep the filling from bubbling over during baking.
• For a darker crust: Broil for 2–3 minutes at the end, watching closely so the potatoes do not burn.

Serving Ideas

Serve Shepherd’s Pie with a fresh salad or a simple vegetable side to balance the rich lamb filling and creamy mashed potatoes. It pairs especially well with Tangy Vinegar Cucumber Tomato Salad, Southern Fried Cabbage, or Crispy Fried Green Tomatoes.

Frequently Asked Questions
