Instructions

1. Boil and Mash Potatoes

   Place potatoes in a large pot and cover with cold water by 1 inch. Add 1 teaspoon salt. Bring to a boil and cook for 15 to 18 minutes until completely fork-tender. Drain well and return to the warm pot. Mash with butter, cream, 1/2 teaspoon salt, and black pepper until smooth. Let cool 5 minutes, then whisk in the egg yolk until silky.

   Texture Cue Smooth, velvety, and thick enough to hold peaks on a spoon.

2. Brown the Meat

   Heat a large skillet or Dutch oven over medium-high heat. Add ground lamb or beef, breaking it up with a wooden spoon for 6 to 8 minutes until browned. Drain all but 1 tablespoon of rendered fat.

   Visual Cue Meat is browned with savory fond on pan bottom.

3. Cook Vegetables & Build Gravy

   Add the diced onion, carrots, and celery to the meat. Cook for 5 minutes until vegetables soften. Add garlic and tomato paste; stir for 1 minute. Sprinkle flour over the mixture and cook 1 minute. Pour in red wine to deglaze, then add beef stock, Worcestershire, rosemary, and thyme. Bring to a simmer for 10 minutes until thick and glossy.

   Texture Cue Gravy thickens to a spoonable stew consistency.

4. Fold in Peas and Transfer

   Remove meat mixture from heat and fold in frozen peas. Pour into a 9x13-inch or 2-quart baking dish and spread evenly. Let sit 5 minutes to form a slight skin.

   Visual Cue Surface stabilizes so potato topping will not sink.

5. Top with Mashed Potatoes

   Dollop the mashed potatoes across the top of the warm filling. Use an offset spatula or back of a spoon to spread potatoes to the edges, sealing the filling. Use a fork to drag decorative ridges across the entire surface. Sprinkle with grated parmesan if desired.

   Visual Cue Distinct parallel fork lines across the entire potato crust.

6. Bake to Golden Perfection

   Bake at 400°F (200°C / 180°C fan) for 25 to 30 minutes, until the filling is bubbling around the edges. If desired, switch to broil for the final 2 to 3 minutes to deeply brown the potato peaks.

   Visual Cue Bubbling gravy around the edges; crisp, deeply browned potato peaks.

7. Rest Before Serving

   Let rest for 10 minutes before scooping. This allows the sauce to settle for clean portions.

   Texture Cue Hearty scoop with stable mashed potato layer over rich meat.
