I absolutely love how the lamb turns out tender and juicy with just the right amount of herbaceous zing, while the vegetables roast alongside, soaking up all those amazing juices.

Why You’ll Love This Recipe
- Juicy, Tender Lamb: The herb marinade and slow roasting lock in moisture and flavor.
- One-Pan Convenience: Roasting lamb and vegetables together means less cleanup and a perfectly harmonized meal.
- Fresh Herb Aroma: Rosemary and thyme add an irresistible fragrance and earthy flavor that’s hard to resist.
- Customizable Veggies: You can easily swap or add vegetables to suit your tastes or what’s in season.
Ingredients You’ll Need
This recipe comes together beautifully with simple, fresh ingredients that complement each other perfectly. My tip is to pick the freshest herbs you can find—they really make all the difference, and the vegetables are best when chosen for their firmness and color.
- Boneless leg of lamb: Opt for a quality cut around 4 to 5 pounds for even cooking; I find boneless easier to carve and serve.
- Olive oil: Use extra virgin for a richer flavor in the marinade.
- Freshly squeezed lemon juice: Adds brightness and balances the lamb’s richness.
- Lemon zest: I always zest just before using to capture that fresh citrus aroma.
- Garlic cloves: Minced or pressed—the more finely, the better for infusing the flavors into the meat.
- Fresh rosemary: Chopped to release the essential oils that make the lamb so fragrant.
- Fresh thyme: Also chopped—fresh is a must here for the best herbal kick.
- Salt and pepper: To taste, but don’t be shy—seasoning is key!
- Russet potatoes: Thick rounds hold their shape well and roast beautifully alongside the lamb.
- Leek stalk: Make sure to wash well to remove grit; adds a subtle onion flavor.
- Baby carrots: Or thick-cut regular carrots for sweetness and color in the roast.
Variations
I love making this recipe my own by changing up the vegetables depending on the season or what’s in my fridge. Feel free to experiment with your favorite root veggies or even add some parsnips or sweet potatoes for a twist. You’ll find that tweaking it to your preference keeps it exciting every time.
- Vegetable Swap: One time, I added parsnips and Brussels sprouts, which gave the roast a lovely earthy and slightly bitter contrast that my family loved.
- Herb Mix: If you don’t have fresh rosemary or thyme, dried herbs work in a pinch—just use about half the amount since dried is more concentrated.
- Spicy Kick: Adding a pinch of crushed red pepper flakes to the marinade gave it a subtle heat that I enjoyed.
How to Make Roasted Leg of Lamb with Vegetables Recipe
Step 1: Marinate the Lamb
Start by mixing the olive oil, lemon juice, lemon zest, chopped garlic, rosemary, thyme, salt, and pepper in a bowl. Rub this aromatic mixture all over the lamb, making sure to coat it evenly. This is where the magic begins—giving the lamb time to soak up these flavors really makes a difference. I usually let it marinate for at least 30 minutes at room temperature, or up to overnight in the fridge if I’m prepping ahead.
Step 2: Prepare the Vegetables
While the lamb marinates, prep your vegetables. Peel and slice the russet potatoes into thick rounds so they don’t get mushy. Clean and slice the leek into thick rounds (and make sure to rinse any dirt out). Finally, if you’re using regular carrots, cut them into thick rounds; baby carrots are perfect as-is. Toss all the veggies with a little olive oil, salt, and pepper, then spread them out in a roasting pan around where the leg of lamb will rest.
Step 3: Roast to Perfection
Preheat your oven to 375°F (190°C). Place the marinated leg of lamb right in the center of the pan on top of the veggies. Roast uncovered for about 90 minutes, or until the internal temperature of the lamb reaches 130-135°F (54-57°C) for medium-rare. If you prefer it more well done, cook it longer accordingly. Halfway through roasting, I like to baste the lamb with its juices and gently stir the vegetables so they cook evenly and soak up all those flavors. This is the step where patience really pays off—resist the urge to overcook, and use a meat thermometer for best results.
Step 4: Rest Before Carving
Once your lamb reaches the perfect doneness, remove it from the oven and cover loosely with foil. Let it rest for about 15-20 minutes—trust me, this step locks the juices in so every slice stays moist and tender. Meanwhile, you can keep the veggies warm in the oven on low heat if needed.
Pro Tips for Making Roasted Leg of Lamb with Vegetables Recipe
- Use a Meat Thermometer: This is the best way to cook lamb perfectly without guessing—it helped me avoid dry or undercooked meat every time.
- Room Temperature Meat: Let your lamb sit out for at least 30 minutes before roasting to promote even cooking.
- Baste and Stir Veggies: Halfway through roasting, baste the lamb with its juices and turn the vegetables so everything cooks evenly and stays flavorful.
- Rest Before Carving: Let the lamb rest to redistribute juices—skip this and you’ll end up with dry slices!
How to Serve Roasted Leg of Lamb with Vegetables Recipe
Garnishes
I like finishing my roast with a sprinkle of fresh chopped parsley or extra rosemary for a pop of color and fresh herbal boost. A few lemon wedges on the side are great too, especially if you or your guests want an extra zing of citrus.
Side Dishes
Since the lamb and veggies roast together, I usually keep sides simple—garlic butter green beans or a light arugula salad with shaved Parmesan work beautifully. For a more indulgent meal, creamy mashed potatoes or a couscous pilaf add extra comfort and texture.
Creative Ways to Present
One evening, I carved the lamb onto a large wooden board with veggies piled high around it and served family-style at the table—it instantly made the meal feel festive and inviting. You can also arrange the meat and vegetables neatly on a platter with sprigs of rosemary as garnish for a polished look.
Make Ahead and Storage
Storing Leftovers
I store leftover lamb and vegetables in airtight containers in the fridge and find they keep nicely for up to 3 days. The flavors actually mellow and blend, which I’ve come to really enjoy in sandwiches or salads the next day.
Freezing
While I usually prefer fresh, if you want to freeze leftovers, slice the lamb and freeze it with a little of the veggies and pan juices in freezer-safe containers. It reheats well when thawed in the fridge overnight, though veggies are best eaten fresh if possible.
Reheating
For reheating, I gently warm slices of lamb and veggies in a covered dish in the oven at a low temperature (around 300°F) to avoid drying out. Adding a splash of broth or covering with foil helps keep everything juicy.
FAQs
-
Can I use bone-in leg of lamb instead of boneless for this recipe?
Absolutely! Bone-in leg of lamb works well too but will require a longer cooking time—usually about 15-20 minutes extra per pound. Just keep an eye on the internal temperature so it reaches your desired doneness.
-
How do I make sure the vegetables don’t overcook?
I recommend cutting your vegetables into thick pieces so they hold their texture better. Also, stirring them halfway through roasting helps cook them evenly without getting mushy. If needed, you can remove the veggies earlier than the lamb and keep warm separately.
-
What’s the best way to season the lamb for maximum flavor?
Marinating the lamb with olive oil, lemon, garlic, and fresh herbs like rosemary and thyme is a winner for me. It infuses the meat with vibrant flavors without overpowering the natural lamb taste. Don’t forget to season generously with salt and pepper!
-
Can I prepare this dish ahead of time?
Definitely! You can marinate the lamb the night before and store it covered in the fridge. The vegetables can also be prepped ahead, making the roasting day a breeze. Just bring the lamb to room temperature before cooking.

Ingredients
Lamb Marinade
- 1 boneless leg of lamb (4.5 lbs)

- Zest from one lemon
- 8 garlic cloves, finely chopped or pressed
- 2 Tbsp chopped fresh rosemary
- 2 Tbsp chopped fresh thyme
- Salt and pepper to taste
Vegetables
- 2 large russet potatoes, washed, peeled, and cut into thick rounds
- 1 leek stalk, washed well and cut into thick rounds
- 1 lb baby carrots (or regular carrots cut into thick rounds)
Instructions
- Prepare the Marinade: In a small bowl, combine olive oil, freshly squeezed lemon juice, lemon zest, finely chopped garlic, chopped rosemary, chopped thyme, salt, and pepper. Mix well to create a fragrant herb marinade.
- Marinate the Lamb: Pat the boneless leg of lamb dry with paper towels. Rub the marinade evenly all over the lamb, making sure to coat it well. For best results, cover the lamb and let it marinate in the refrigerator for at least 1 hour, or up to overnight to develop flavor.
- Preheat the Oven: When ready to cook, preheat your oven to 375°F (190°C) to ensure even roasting.
- Prepare the Vegetables: Arrange the sliced potatoes, leek rounds, and baby carrots in a large roasting pan. Drizzle with a little olive oil and season lightly with salt and pepper. Toss to coat evenly.
- Roast the Lamb and Vegetables: Place the marinated leg of lamb on top of the vegetables in the roasting pan. Insert a meat thermometer into the thickest part of the lamb. Roast in the preheated oven for about 90 minutes or until the internal temperature reaches 135°F (57°C) for medium-rare, or adjust cooking time for preferred doneness.
- Rest the Meat: Remove the lamb from the oven and transfer to a cutting board. Tent loosely with foil and let rest for 15 minutes to allow the juices to redistribute, ensuring tender and juicy meat.
- Serve: Slice the rested leg of lamb against the grain and serve it alongside the roasted vegetables. Spoon some of the pan juices over the meat and vegetables for added flavor.
