Shepherd's Pie

Instructions

• Preheat the oven to 425°F (220˚C).
• Heat the oil in a large pan over medium-high heat until shimmering. Add the ground lamb, season with salt and pepper, and fry for 5 minutes, until cooked through.
• Add the onion, carrots, garlic, thyme, and rosemary, stir, and cook for about 10 minutes, or until the veggies are softened and the meat is well-browned.
• Add the tomato paste and Worcestershire sauce and stir to incorporate. Cook for 1-2 minutes, stirring constantly, until the liquid evaporates and the meat is aromatic.
• Pour in the red wine and reduce until almost completely evaporated.
• Add the chicken stock, bring to a boil, and cook the meat until the stock has evaporated, 5 minutes.
• Meanwhile, cook the potatoes in a large pot of boiling salted water until tender. Drain, then return to the hot pan over low heat to dry out a bit.
• Transfer the potatoes to a large bowl and mash until smooth.
• Add salt, the butter, egg yolks, sour cream, and Parmesan cheese. Fold until well combined.
• Transfer the potatoes to a piping bag or zip-top bag fitted with a star tip.
• Spoon the lamb mixture into a large baking dish. Pipe the golden mashed potatoes over the lamb.
• Bake for 30 minutes, until the potatoes are golden brown.
• Enjoy!
