Ingredients
Scale
2 tablespoons olive oil
1 large onion, chopped
2 carrots, diced
2 celery stalks, diced
1.5 pounds ground lamb
2 cloves garlic, minced
1 tablespoon tomato paste
1 teaspoon dried thyme
1 teaspoon dried rosemary
1 tablespoon Worcestershire sauce
1 cup beef broth
1 cup frozen peas
Salt and black pepper to taste
3 pounds Russet potatoes, peeled and quartered
1/2 cup milk
4 tablespoons unsalted butter
1/2 cup shredded sharp cheddar cheese (optional, for topping)
Instructions
Prepare the potatoes: Place potatoes in a large pot, cover with cold, salted water, and bring to a boil. Cook until fork-tender, about 15 to 20 minutes. Drain well.
Mash the potatoes: Return potatoes to the hot pot. Add milk and butter. Mash until smooth and creamy. Season with salt and pepper. Set aside.
Cook the filling base: Heat olive oil in a large oven-safe skillet or Dutch oven over medium heat. Add onion, carrots, and celery. Cook until softened, about 5 to 7 minutes.
Brown the lamb: Add ground lamb to the skillet. Break it up with a spoon and cook until browned. Drain off excess fat.
Flavor the filling: Stir in garlic, thyme, and rosemary. Cook for 1 minute until fragrant. Add tomato paste and cook for 1 minute more.
Simmer the sauce: Pour in Worcestershire sauce and beef broth. Bring the mixture to a simmer, scraping up any browned bits from the bottom of the pan. Let it cook until the sauce thickens slightly, about 5 minutes.
Finish the filling: Stir in the frozen peas. Taste and adjust seasoning with salt and pepper. If you are not using an oven-safe skillet, transfer the filling to a 9×13 inch baking dish.
Top the pie: Carefully spread the mashed potatoes evenly over the meat filling. Use a fork to create texture on the potato surface; this helps it brown. Sprinkle with cheddar cheese if you are using it.
Bake the pie: Bake in a preheated oven at 400 degrees Fahrenheit (200 degrees Celsius) for 20 to 25 minutes, or until the filling is bubbly and the potato topping is golden brown.
Rest and serve: Let the pie rest for 10 minutes before serving. This helps the filling set.
Notes
For a richer flavor, brown the potatoes slightly before mashing.
If you prefer beef, substitute ground beef for the lamb; this is traditionally called Cottage Pie.
If you are planning your weekly meals, this recipe works well with meal planning for leftovers.
