This lamb pie recipe turns humble lamb shoulder into a rich, deeply savory filling wrapped in golden, flaky pastry. It fills the kitchen with the smell of rosemary and thyme long before it ever hits the table. I make this whenever I want something that feels like a proper Sunday dinner without spending all day in the kitchen. The lamb turns fork tender as it simmers in a thick gravy with carrots, onions, and celery, then gets tucked under a buttery pastry lid and baked until deeply golden.

Instructions
Trim excess fat from the lamb shoulder and cut into 1-inch cubes. Pat the lamb dry with paper towels. Dice the onion, carrots, and celery into small, even pieces. Mince the garlic and set aside separately.
Heat olive oil in a large Dutch oven over medium-high heat. Season lamb cubes generously with salt and pepper. Sear the lamb in a single layer for 2-3 minutes per side until a deep brown crust forms, working in batches if needed. Transfer to a plate and set aside.
Reduce heat to medium and add the diced onion, carrots, and celery to the pot. Cook for 5-6 minutes until the onion is soft and translucent. Stir in the minced garlic and cook for 30 seconds. Sprinkle flour over the vegetables and stir constantly for 1 minute. Slowly pour in the beef stock while stirring, scraping up any browned bits. Stir in the Worcestershire sauce and tomato paste until combined.
Return the browned lamb and any juices to the pot. Add the thyme, rosemary, and bay leaves. Bring to a gentle boil, then reduce the heat to low, cover, and simmer for 1 hour to 1 hour 15 minutes until the lamb is fork tender and the gravy has thickened. Stir in the frozen peas during the last 5 minutes of cooking. Remove bay leaves and season with salt and pepper to taste.
Remove the pot from the heat and let the filling cool for 20-30 minutes. Cooling before assembly prevents soggy pastry.
Preheat the oven to 400 degrees Fahrenheit. Roll out one sheet of puff pastry and line the bottom and sides of a 9-inch pie dish, letting excess hang over the edge. Spoon the cooled lamb filling into the pastry-lined dish. Roll out the second sheet of pastry and lay it over the top. Trim excess pastry, crimp the edges to seal, and cut 2-3 small slits in the top crust. Brush the beaten egg evenly over the top crust.
Place the pie on a rimmed baking sheet and bake for 30-35 minutes until the pastry is deeply golden and puffed. If the edges brown too quickly, loosely tent with foil.
Remove the pie from the oven and let it rest for at least 10 minutes before slicing. This allows the gravy to set. Slice into wedges and serve warm.
Notes
Do not skip searing the lamb, since that browned crust builds most of the flavor in the gravy.
Cool the filling completely before adding the top crust to prevent soggy pastry.
Keep your pastry cold until you are ready to use it, since warm pastry is much harder to work with.
Cut a few steam vents in the top crust so the pie does not puff up unevenly.
Let the pie rest before slicing so the filling has time to set.
Swap the puff pastry for a shortcrust pastry for a more rustic, sturdy crust.
Stir in a splash of red wine with the stock for a deeper, more complex gravy.
Add sliced mushrooms with the vegetables for extra earthiness.
Store leftover pie in an airtight container in the refrigerator for up to 4 days. Reheat individual slices in a 350 degree Fahrenheit oven for about 15 minutes.
To freeze, wrap the unbaked assembled pie tightly in plastic wrap and foil, then freeze for up to 3 months. Bake from frozen at 375 degrees Fahrenheit, adding about 20 extra minutes to the bake time.
