How we chose
Research-backed · reviewed Aug 2026
We matched the twelve-inch footprint, fitted lid, tri-ply heat distribution, 600°F oven and broiler rating, current model 41126 and UPC, ownership burden, and exact Amazon identity. Kwilt has not cooked with this pan.
All-Clad D3 12-Inch Fry Pan with Lid · 41126: Its twelve-inch cooking surface gives rice, shrimp, meat, and vegetables room to cook evenly, while the fitted lid and 600°F oven rating cover both the lidded stovetop method and the shepherd's-pie oven finish. Trade-off: It is a premium-priced pan, food can stick without sound preheating and fat control, and the long handle plus lid need more storage room than a basic skillet.
Another workable path: Use another oven-safe 12-inch skillet with a well-fitting lid; if the handle has a lower heat limit, transfer oven-finished food to a suitable baking dish.

1× recipe · Makes 6 servings

2 pounds Yukon Gold potatoes, peeled and cut into chunks
2 teaspoons kosher salt, divided
4 tablespoons unsalted butter, divided
1/2 cup whole milk, warmed
1 large egg yolk
1 tablespoon neutral oil
1 1/2 pounds ground lamb
1 large yellow onion, finely diced
2 carrots, cut into 1/4-inch dice
3 garlic cloves, minced
2 tablespoons tomato paste
2 tablespoons all-purpose flour
1 cup dry red wine
1 1/2 cups low-sodium lamb or beef stock
1 tablespoon Worcestershire sauce
1 teaspoon fresh thyme leaves
1 cup frozen peas
1/2 teaspoon black pepper

Instructions

Boil potatoes in water seasoned with 1 teaspoon salt until completely tender. Drain and return to the hot pot 2 minutes to steam dry. Mash with 3 tablespoons butter, warm milk, egg yolk, and 1/2 teaspoon salt; keep warm.
Heat oil in a . Brown lamb deeply, breaking it into coarse pieces; spoon off all but 1 tablespoon fat. Add onion and carrots and cook 8 minutes, then garlic and tomato paste for 2 minutes.
Stir in flour for 1 minute. Add wine and reduce by half, then stock, Worcestershire, thyme, pepper, and remaining salt. Simmer until gravy is thick and leaves a trail, 8 to 10 minutes. Fold in peas and level the filling.
Spoon potatoes over filling and spread completely to the skillet edge to seal. Ridge with a fork and dot with remaining butter. Bake at 425°F for 20 minutes, then broil until browned. Rest 10 minutes.

About this recipe

Shepherd’s pie is associated with Britain and Ireland and, by definition, uses lamb beneath mashed potato; the skillet presentation is a modern household convenience that preserves the traditional meat, gravy, vegetable, and potato structure.

Although early usage could be fluid, modern convention generally distinguishes lamb shepherd’s pie from beef cottage pie. This American-roster version respects that current distinction by using lamb. Sealing mash to the skillet edge contains bubbling gravy. This Kwilt version follows the reviewed household adaptation: Use the highly rated lamb form and one-skillet workflow, making gravy reduction and a complete potato seal explicit for repeatable portions.
