Save This dish features a bone-in leg of lamb carefully infused with garlic and rubbed in a herb blend including rosemary and thyme. The lamb roasts alongside a medley of root vegetables like carrots, parsnips, potatoes, and onions, all tossed in olive oil and seasoning. The vegetables caramelize beautifully while the lamb reaches a perfect medium-rare, creating an elegant and comforting main course for six servings. Resting the lamb ensures juicy tenderness, and optional parsley and pan juices enhance the final presentation.
Discovering this roasted lamb with root vegetables was like stumbling upon a hidden treasure in my grandmother's kitchen. The rich aroma of garlic and rosemary roasting alongside the tender lamb instantly made it a comfort food classic for me.
I remember the first time unexpected guests arrived late and I barely had time to prepare this dish. Somehow, the flavors came together perfectly, and everyone kept asking for seconds.
Ingredients
- Bone-in leg of lamb: I always choose bone-in for deeper flavor and juicier meat
- Fresh rosemary and thyme: These herbs elevate the dish with their piney freshness, always chopped just before use
- Root vegetables: Carrots, parsnips, potatoes, sweet potatoes, and onions bring natural sweetness and texture contrast
- Olive oil: Use good quality for roasting and coating the lamb to help herbs stick and brown evenly
- Garlic: Slicing and inserting into the lamb infuses subtle garlicky warmth without overpowering
- Salt and black pepper: Essential to balance and highlight all the flavors
Instructions
- Get Everything Ready:
- Preheat the oven to 200°C (400°F) and prepare your roasting pan with a rack to let air circulate for even cooking
- The Flavorful Prep:
- Slice garlic and insert into small incisions made all over the lamb, then rub the lamb with olive oil and coat thoroughly with fresh rosemary, thyme, salt, and freshly ground black pepper
- Arranging the Roast:
- Place the lamb on the rack in your roasting pan, then toss all root vegetables and onions with olive oil, salt, and pepper before arranging them around the lamb to soak up those lovely juices
- Roasting Time:
- Start roasting at 200°C for 20 minutes to get a beautiful sear, then reduce heat to 180°C (350°F) and roast for an additional 1 hour and 10 to 20 minutes until reaching an internal temperature of 60°C (140°F) for medium-rare. Don't forget to stir the vegetables halfway through so they caramelize evenly
- Resting and Serving:
- Transfer the lamb to a cutting board and tent loosely with foil to rest for 15 minutes. If the vegetables need more color, pop them back into the oven to finish roasting. Carve the lamb and serve with the roasted vegetables, sprinkled parsley, and pan juices for extra richness
Save This dish became more than just food on a chilly winter evening when friends gathered, laughter filled the room, and the roasted lamb created a memory we all carried for years.
Keeping It Fresh
Leftover roasted lamb stays juicy when wrapped tightly in foil and refrigerated. Reheat gently with a splash of broth to keep it tender and avoid drying out the meat.
When You're Missing Something
If you don't have fresh rosemary or thyme, dried herbs can work but use them sparingly so flavors don't become too intense or dusty.
Serving Ideas That Clicked
Serving this lamb with a simple green salad or crusty bread balances the richness and adds a fresh element to the plate.
