Directions

1. Stir potatoes, sour cream, cream cheese, 1 tablespoon butter, egg yolk, 1/2 teaspoon salt, and 1/2 teaspoon black pepper together in a bowl until smooth.
2. Heat olive oil in a cast iron skillet or nonstick pan over medium-high heat.
3. Add ground lamb, reduce heat to medium, and cook, stirring frequently, until browned and crumbly, 4 to 5 minutes.
4. Pour off excess grease and season lamb with salt and black pepper to taste.
5. Stir tomatoes with juice, onion, and carrot into ground lamb; simmer until vegetables are tender, 5 to 10 minutes.
6. Add peas, reduce heat to low, and cook, stirring frequently, until peas are warmed, 2 to 3 minutes.
7. Heat beer in a saucepan over medium heat; add beef bouillon. Cook and stir beer mixture until bouillon is dissolved, about 5 minutes.
8. Heat remaining 1 tablespoon butter in a separate pan over medium-low heat until sizzling.
9. Whisk flour into butter until thick and paste-like, about 1 minute. Stir beer mixture and Worcestershire sauce into flour mixture until gravy is smooth and thickened, 2 to 3 minutes. Stir gravy into lamb mixture and simmer until mixture is thickened, at least 5 minutes.
10. Set oven rack about 6 inches from the heat source and preheat the oven's broiler. Grease a 9x12-inch baking dish.
11. Pour lamb mixture into the prepared baking dish. Carefully spoon mashed potatoes over lamb mixture, covering like a crust.
12. Sprinkle Cheddar cheese, parsley, and paprika over mashed potatoes.
13. Broil in the preheated oven until crust is browned and cheese is melted, 4 to 5 minutes. Cool for about 5 minutes before serving.
