• Easy to make ahead and reheat.

Ingredients

Makes 4–6 servings

For the mashed potato topping

• 2 lb (900 g) potatoes, Yukon Gold or russet, peeled and cut into 1–1½ inch pieces
• 4 tbsp (60 g) unsalted butter
• 1⁄3–1⁄2 cup (80–120 ml) whole milk or cream, warmed
• Salt and freshly ground black pepper, to taste
• Optional: 2 tbsp sour cream or cream cheese for extra tang and creaminess

For the meat filling

• 1 tbsp vegetable oil or olive oil
• 1 lb (450 g) ground lamb or ground beef
• 1 medium onion, finely chopped
• 2 carrots, diced small (about 1 cup)
• 1 cup frozen peas (optional)
• 2 cloves garlic, minced
• 2 tbsp tomato paste
• 1 cup (240 ml) beef or chicken stock
• 1 tbsp Worcestershire sauce
• 1 tsp fresh thyme leaves or ½ tsp dried thyme
• 2 tbsp all-purpose flour (to thicken)
• Salt and pepper, to taste

Equipment

• Medium saucepan for potatoes
• Large skillet or sauté pan for filling
• 8×8-inch (20×20 cm) or similar ovenproof dish
• Potato masher or ricer

Instructions

1. Cook the potatoes

1. Place potatoes in a saucepan and cover with cold, salted water. Bring to a boil and simmer until tender, about 15–20 minutes.
2. Drain well and return to the hot pot for 1 minute to dry out. Mash with butter, then slowly stir in warm milk to reach a smooth, spreadable consistency. Season with salt and pepper and fold in sour cream if using. Keep warm.

2. Make the meat filling

1. Preheat oven to 400°F (200°C).
2. Heat oil in a large skillet over medium-high heat. Add the onion and carrots; cook 5–7 minutes until softened.
3. Add the ground lamb or beef and cook, breaking up with a spoon, until browned and no longer pink, about 6–8 minutes. Drain excess fat if the pan is very greasy.
4. Stir in garlic and tomato paste; cook 1 minute until fragrant. Sprinkle the flour over the meat and stir to combine. Cook 1 minute to remove raw flour taste.
5. Gradually add the stock, scraping up any browned bits from the pan. Stir in Worcestershire sauce and thyme. Simmer until the mixture thickens slightly, 3–5 minutes.
6. Stir in frozen peas (if using). Taste and season with salt and pepper.

3. Assemble and bake

1. Spoon the meat filling into the ovenproof dish and spread into an even layer.
2. Top with the mashed potatoes, spreading to cover the filling. For texture, use a fork to create ridges on the surface—these brown nicely.
3. Place in the oven and bake until the top is golden and the filling is bubbling, 20–25 minutes. For extra color, broil 1–2 minutes at the end—watch closely to avoid burning.
4. Let rest 5–10 minutes before serving so the filling sets.

Timing

• Prep: 20–25 minutes
• Cook: 30–35 minutes
• Total: 50–60 minutes

Make-Ahead & Storage

• Assemble in the baking dish, cover, and refrigerate up to 24 hours before baking. Add 5–10 minutes to baking time if chilled.
• Leftovers keep in an airtight container for 3–4 days. Reheat in a 350°F (175°C) oven until warmed through, about 15–20 minutes, or microwave individual portions.

Tips for success

• Use starchy potatoes (Yukon Gold or russet) for fluffy mash that holds its shape.
• Warm the milk before adding to the potatoes to keep the mash smooth and hot.
• If the filling is too thin, simmer a few minutes longer or add a touch more flour mixed with cold water.
• For a crisper top, mix 1⁄4 cup grated cheddar into the potato topping before baking.

Variations

• Vegetarian: Replace meat with a lentil and mushroom mixture; use vegetable stock and add soy sauce for depth.
• Cheesy shepherd’s pie: Stir 1 cup grated cheddar through the mashed potatoes or sprinkle on top before baking.
• Root-veg twist: Mix mashed parsnips or sweet potatoes with the potatoes for a different flavor profile.

Serving

Serve hot with a simple green salad or steamed greens and a squeeze of lemon for brightness. This dish pairs well with a squeeze of chutney or pickles on the side for contrast.

Enjoy a classic, cozy dinner that’s straightforward to make and even better the next day.
