Ingredients

Scale
  • 1.5 pounds (700g) lamb leg or shoulder, boneless, trimmed of excess fat
  • 3 cloves garlic, minced
  • 2 tablespoons olive oil (extra virgin recommended)
  • 1 tablespoon fresh rosemary, chopped (or 1 teaspoon dried rosemary)
  • 1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme)
  • Juice of 1 lemon
  • Salt and freshly ground black pepper, to taste
  • Optional: pinch of red pepper flakes
  • 2 pounds (900g) Yukon Gold potatoes, peeled and cut into chunks
  • 4 tablespoons unsalted butter, softened
  • 1/2 cup (120ml) whole milk, warmed (or dairy-free substitute like oat milk)
  • Salt and white pepper, to taste
  • Optional: 2 tablespoons sour cream or crème fraîche
  • Chopped fresh chives or parsley for garnish

Instructions

  1. Marinate the Lamb: In a mixing bowl, combine olive oil, minced garlic, chopped rosemary, thyme, lemon juice, salt, black pepper, and red pepper flakes if using. Add the lamb and rub the marinade all over the meat. Cover and refrigerate for at least 30 minutes, or up to 4 hours for deeper flavor.
  2. Prepare the Potatoes: Peel and cut the potatoes into evenly sized chunks (about 1.5 inches). Place them in a large pot and cover with cold water. Add a pinch of salt and bring to a boil over high heat. Reduce heat to medium and simmer until potatoes are fork-tender, about 15-20 minutes.
  3. Cook the Lamb: Preheat oven to 400°F (200°C). Heat skillet or roasting pan over medium-high heat. Sear the lamb on all sides until golden brown, about 3-4 minutes per side. Transfer skillet to oven and roast for 20-25 minutes for medium-rare (internal temperature about 135°F/57°C). Let lamb rest for 10 minutes before slicing.
  4. Mash the Potatoes: Drain cooked potatoes and return to pot. Mash with potato masher or ricer until smooth. Add softened butter, warmed milk, and sour cream if using. Season with salt and white pepper. Stir gently until creamy and fluffy. Adjust seasoning to taste.
  5. Serve: Slice rested lamb against the grain into thick slices. Plate with a generous scoop of creamy mashed potatoes. Garnish with chopped chives or parsley.

Notes

Do not skip resting the lamb after roasting to keep it juicy. Use a meat thermometer for perfect doneness. Warm the milk before adding to mashed potatoes for a silky texture. A cast iron skillet helps achieve a great sear. For dairy-free mashed potatoes, substitute butter with olive oil and milk with coconut or almond milk.
