150 gpeas (fresh or frozen)
30 mlolive oil
5 gsalt and black pepper
5 gdried thyme
15 mlWorcestershire sauce
Instructions
1PREPARE THE VEGETABLES: Peel and dice the onions, carrots, and celery into small, uniform pieces approximately 5mm in size. This ensures even cooking and creates a refined texture throughout the filling. Finely mince the garlic cloves and set all vegetables aside in separate bowls for easy access during cooking.
2COOK THE LAMB FILLING: Heat the olive oil in a large, heavy-bottomed pan or Dutch oven over medium-high heat until shimmering. Add the ground lamb in batches, breaking it apart with the back of a wooden spoon, and cook for 8-10 minutes until deeply browned. Drain excess fat if necessary, leaving approximately 2 tablespoons for flavor. The lamb should be caramelized with no pink remaining.
3BUILD THE AROMATICS: Add the diced onions, carrots, and celery to the browned lamb and cook over medium heat for 8-10 minutes, stirring occasionally, until the vegetables are softened and the onions are translucent. The vegetables will release their natural juices and deglaze the pan, capturing all the flavorful browned bits. Add the minced garlic and cook for another minute until fragrant.
4CREATE THE SAUCE: Stir in the tomato paste and cook for 2 minutes, stirring constantly, to caramelize it slightly and deepen its flavor. Pour in the beef stock and Worcestershire sauce, then add the dried thyme, salt, and black pepper to taste. Bring to a simmer over medium heat and cook uncovered for 10-12 minutes until the sauce reduces and thickens slightly to coat the back of a spoon. The sauce should be rich and coat the meat and vegetables evenly.
5FINISH THE MEAT LAYER: Gently fold in the fresh or frozen peas during the last 2 minutes of cooking, stirring gently to distribute them evenly throughout the filling. Taste the filling and adjust seasonings with additional salt, pepper, or Worcestershire sauce as needed. Transfer the hot filling to a 9x13 inch baking dish, spreading it in an even layer. The filling should be warm and steaming when you proceed to the next step.
6PREPARE THE MASHED POTATO TOPPING: While the filling cooks, peel the potatoes and cut them into 2-inch chunks. Place them in a large pot of cold, salted water and bring to a boil over high heat. Cook for 12-15 minutes until completely tender and a fork easily pierces the largest piece. Drain well in a colander and return to the pot.
7MAKE CREAMY POTATOES: Add the butter and warm milk to the drained potatoes and mash using a potato ricer or masher until smooth and creamy with no lumps. The potatoes should be pale and fluffy with a light, mousse-like texture. Season with salt and white pepper to taste, then spread the mashed potatoes evenly over the lamb filling using a spatula or the back of a spoon, sealing the filling completely.
8BAKE UNTIL GOLDEN: Preheat your oven to 190°C (375°F). Place the assembled pie on a baking sheet to catch any drips and bake for 20-25 minutes until the potato topping is golden brown and a skewer inserted through the potatoes into the filling comes out hot. The top should develop a rich, appetizing golden crust while remaining creamy underneath. If the top browns too quickly, loosely tent with aluminum foil.
9REST AND SERVE: Remove from the oven and let the pie rest for 5 minutes before serving. This allows the filling to set slightly and makes portioning easier. Serve directly from the baking dish or portion into individual bowls, ensuring each serving includes both the lamb filling and creamy potato topping. Garnish with fresh parsley if desired and serve piping hot.
