Ingredients

Scale
  • 1.5 lbs bone-in lamb leg steak or lamb chops
  • 1 lb baby potatoes, halved (Yukon Gold or red potatoes)
  • 3 medium carrots, peeled and cut into 2-inch pieces
  • 2 tablespoons fresh rosemary, chopped
  • 4 garlic cloves, minced
  • 3 tablespoons extra virgin olive oil
  • Zest of 1 lemon
  • 1.5 teaspoons sea salt, to taste
  • 1 teaspoon freshly ground black pepper, to taste
  • Optional: 1 tablespoon Dijon mustard

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. Pat the lamb steaks dry with paper towels. If using Dijon mustard, rub it evenly over each piece. Sprinkle with half the rosemary, garlic, salt, and pepper. Set aside to marinate briefly while prepping the veggies.
  3. In a large bowl, toss the halved baby potatoes and carrot pieces with olive oil, remaining rosemary, garlic, lemon zest, salt, and pepper until evenly coated.
  4. Spread the veggies out in a single layer on a large rimmed baking sheet, leaving space for the lamb pieces. Place the lamb on the pan, skin or fat side up if applicable. Avoid overcrowding.
  5. Roast on the middle rack for 25-30 minutes, flipping the lamb halfway through (around 15 minutes). The veggies should be tender and starting to brown, and the lamb should have a golden crust.
  6. Check the internal temperature of the lamb with a meat thermometer; aim for 135°F (57°C) for medium-rare or cook longer for medium.
  7. Remove the lamb from the oven and cover loosely with foil. Let it rest for 5-10 minutes. If veggies need more color, roast them for an additional 5 minutes.
  8. Slice the lamb against the grain and serve with the roasted potatoes and carrots. Drizzle any pan juices over the top.

Notes

Pat lamb dry before seasoning to ensure a crispy crust. Do not overcrowd the pan to allow proper roasting instead of steaming. Flip lamb halfway through roasting for even browning. Rest meat after roasting to retain juices. Use fresh herbs for best flavor. If oven runs hot, check veggies early to prevent burning. Optional: add smoked paprika or chili flakes for extra flavor.
