Shepherd's pie with Guinness is a hearty and flavorful twist on the classic dish. This comforting casserole features a rich filling of tender ground lamb or beef, vegetables, and aromatic herbs, all simmered in a savory gravy infused with the distinct notes of Guinness stout. Topped with creamy mashed potatoes and baked until golden and bubbling, it's a satisfying and indulgent meal perfect for colder days.
Preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius) and gather all the required ingredients.
Heat a large skillet or Dutch oven over a medium-high heat. Add the ground beef or lamb to the skillet, breaking it up with a spoon or spatula, and cook until browned. Remove from the pan and set aside.
In the same pan, add the diced onion and carrots to the skillet and cook until they soften, stirring occasionally. Add the meat back into the pan.
Stir in the minced garlic, thyme, and Worcestershire sauce and cook for an additional minute, allowing the flavors to meld.
Stir in the tomato paste and flour, coating the meat and vegetables evenly.
Pour in the Guinness stout and beef stock, stirring well to combine. Bring the mixture to a simmer and let it cook for about 10 minutes, allowing the flavors to develop and the liquid to reduce slightly.
Stir in the frozen peas and season with salt and pepper to taste.
In a separate pot, boil the potatoes until tender. Drain and return them to the pot.
Mash the potatoes with heavy cream, butter, egg yolks, salt, and half of the parmesan cheese to create creamy mashed potatoes.
To assemble the shepherd’s pie, spread the meat and vegetable mixture evenly in a 8x10-inch baking dish.
Top the filling with a generous layer of the creamy mashed potatoes, using a spatula or fork to create texture on the surface.
Sprinkle the remaining grated Parmesan cheese over the top for a flavorful crust.
Place the baking dish in the preheated oven and bake for 18-20 minutes, or until the potatoes turn golden and the filling is bubbling. Broil on high for the last few minutes for an extra crunchy crust.
Once cooked, let the Shepherd's Pie rest for a few minutes before serving.
