This recipe takes about an hour and fifteen minutes from start to finish. The long simmer ensures the meat is tender and the sauce is thick. It yields a warm, filling dinner for four people.
Why this works
- Simmering the meat in beef broth creates a thick, savory gravy for the base.
- Ruffling the mashed potatoes with a fork creates ridges that turn crispy as the pie bakes.
- Cooking the potatoes while the meat simmers saves time in the kitchen.
Ingredients you'll need
- Ground lamb: This is the traditional meat for this dish. You can substitute ground beef if you have that on hand.
- Potatoes: Russet or Yukon Gold potatoes yield the smoothest, fluffiest mash.
- Tomato paste: Adds depth and a slight sweetness to the savory gravy.
- Beef broth: Use a low-sodium version so you can control the salt level in the finished dish.

How to make it
Step 1: Brown the meat
Sauté the onions and carrots until soft. Add the ground lamb and cook until browned, making sure it reaches 160°F (71°C).
Step 2: Simmer the filling
Stir in the tomato paste, Worcestershire sauce, and beef broth. Cover and let it simmer so the flavors meld and the sauce reduces.
Step 3: Prepare the potatoes
Boil the potato chunks until they are soft enough to pierce with a fork. Drain the water and mash them with butter and milk.
Step 4: Assemble and bake
Pour the filling into a baking dish and spread the mashed potatoes on top. Bake until the edges bubble and the top turns golden brown.
Serve it with
Serve this warm casserole with a simple green salad or a side of steamed green beans.
Storage and reheating
