Shepherd's Pie with Minced Lamb and Leeks
This Shepherd’s Pie with Minced Lamb and Leeks is a refined take on the traditional British comfort dish. The sweetness of slowly braised leeks paired with rich, savory minced lamb creates a warming, balanced flavor profile. The creamy mashed potato topping is golden and crisp on the outside and buttery-soft beneath—ideal for cozy family dinners or elegant rustic entertaining.

Ingredients
For the Filling:
2 tablespoons olive oil - extra virgin for best flavor
1 pound ground lamb (minced lamb) - preferably grass-fed- 2 cups leeks - cleaned thoroughly and thinly sliced (white and light green parts only)
1 cup carrots - small dice
3 cloves garlic - minced
1 tablespoon tomato paste
1 teaspoon Worcestershire sauce
½ cup red wine - optional, for depth of flavor
1 cup beef stock - low sodium preferred ; or lamb stock
1 teaspoon thyme - fresh thyme leave ; or 1/2 tsp dried thyme
½ teaspoon kosher salt - to taste
¼ teaspoon ground black pepper - freshly ground
For the Mashed Potato Topping:
2 ½ pounds russet potatoes - peeled and quartered- ½ cup whole milk - warm
¼ cup unsalted butter - softened- ½ teaspoon kosher salt
Instructions
- Preheat your oven to 375°F (190°C).
- In a large skillet over medium heat, warm the olive oil. Add the minced lamb and cook for 6–8 minutes, breaking it up with a wooden spoon until browned and cooked through. Drain excess fat if needed.
- Add the leeks and carrots to the lamb. Sauté for 5–6 minutes until softened and fragrant. Stir in garlic and tomato paste, cooking for 1 minute to deepen flavor.
- Deglaze the pan with red wine if using, letting it reduce for 2–3 minutes. Stir in Worcestershire sauce, stock, thyme, salt, and pepper. Simmer for 10–12 minutes until the mixture thickens slightly. Remove from heat and set aside.
- While the filling cooks, place the peeled and quartered potatoes in a large saucepan. Cover with cold water and add a generous pinch of salt. Bring to a boil and simmer for 15–20 minutes until fork-tender.
- Drain the potatoes in a colander and return them to the hot saucepan. Allow steam to escape for a minute. Add warm milk, butter, and salt. Mash until smooth and creamy. Adjust seasoning as needed.
- Transfer the lamb filling to a 9x13-inch oven-safe dish and spread evenly. Spoon mashed potatoes over the top, smoothing with an offset spatula or fork to create ridges that will crisp during baking.
- Bake in the preheated oven for 20–25 minutes until the surface is golden-brown and the edges are bubbling. Optionally broil on high for 2–3 minutes for extra crispness. Let rest for 5–10 minutes before serving.
Notes
- For a dairy-free topping, use olive oil and unsweetened almond milk instead of butter and milk.
- Substitute ground turkey or beef for lamb if preferred.
- For extra richness, stir in a splash of cream or grated cheddar into the mash.
