Ingredients
Here is what I use for this recipe and each ingredient plays an important role in the final result.

- Leg of lamb: The main protein that becomes tender and flavorful when roasted slowly.
- Fresh rosemary: Adds an earthy herbal aroma that pairs naturally with lamb.
- Garlic cloves: Infuse the meat with savory depth and richness.
- Olive oil: Helps carry flavors and promotes even browning during roasting.
- Salt: Enhances the natural taste of the lamb.
- Black pepper: Adds gentle heat and balance.
- Fresh parsley: Brings freshness to the herb filling and final presentation.
- Kitchen twine: Keeps the lamb compact for even cooking.
Tools You’ll Need
- Cutting board: Provides a stable surface for seasoning and stuffing the lamb.
- Sharp knife: Allows precise cuts to open the meat and slice after roasting.
- Small bowl: Used to mix herbs garlic and oil evenly.
- Roasting pan: Holds the lamb securely and collects flavorful juices.
- Roasting rack: Elevates the lamb so heat circulates evenly.
- Oven: Cooks the lamb slowly to achieve tenderness and proper doneness.
- Meat thermometer: Ensures accurate internal temperature for best results.
Instructions
Step 1 Prepare the Lamb
I begin by placing the leg of lamb on a cutting board and patting it dry then I make shallow cuts across the surface so the seasoning can penetrate deeply and flavor every part of the meat.
Step 2 Season and Stuff

I mix chopped rosemary garlic parsley olive oil salt and pepper in a bowl then I rub this mixture generously over the lamb pressing it into the cuts so the herbs stay in place while roasting.
Step 3 Tie and Rest

I roll the lamb into a compact shape and secure it with kitchen twine then I let it rest briefly at room temperature so it cooks more evenly once it goes into the oven.
Step 4 Roast the Lamb

I place the lamb on a rack inside a roasting pan and roast it until the exterior turns golden and the interior reaches the desired temperature adjusting time based on how well done I want it.
Step 5 Rest and Slice

After roasting I remove the lamb from the oven and let it rest so the juices redistribute then I slice it carefully to reveal tender herb filled layers.
Tips
From my experience letting the lamb rest properly makes a noticeable difference in juiciness and I also recommend using fresh herbs rather than dried because they create a cleaner brighter flavor that stands out after roasting.
Ways to Serve
I like serving this Roast Leg of Lamb with Rosemary &Garlic alongside roasted vegetables or creamy mashed potatoes because they absorb the juices beautifully and it also works well with a fresh salad when I want a lighter balance.
Storage Instructions
Leftover lamb stores well when wrapped tightly and kept refrigerated and I usually slice it before storing so it reheats evenly while staying tender for sandwiches salads or simple reheated meals.
