Step‑by‑Step Instructions for Juicy Roasted Boneless Leg of Lamb with Dijon Herb Paste

Step 1: Prep Pan and Lamb
Start by lining a rimmed baking sheet with aluminum foil for easy cleanup. Place an oven-safe rack inside the sheet and preheat your oven to 425°F (218°C). Untie the boneless leg of lamb, unrolling it carefully, and trim any excess fat to ensure even cooking and maximum flavor as you prepare your Roasted Boneless Leg of Lamb.

Step 2: Make Herb Paste
In a medium mixing bowl, whisk together ¼ cup of extra virgin olive oil, ¼ cup of Dijon mustard, minced garlic cloves, dried Herbes de Provence, kosher salt, and freshly ground black pepper until the mixture becomes a smooth and emulsified paste. This Dijon herb paste is key to infusing your lamb with rich flavors, making the Roasted Boneless Leg of Lamb truly unforgettable.

Step 3: Season Lamb
Spread one-third of the herb paste generously inside the opened lamb, then roll it back up tightly and secure it with kitchen twine. Rub the remaining herb paste all over the outside of the roast, coating it evenly. This step is crucial for creating a flavorful crust on your Roasted Boneless Leg of Lamb that complements the tender meat inside.

Step 4: Preheat Oven
With your lamb ready, ensure your oven is preheated to 425°F (218°C). This high heat will help create a beautiful crust on the lamb in the initial cooking phase. Placing the lamb in the oven now will set the stage for the savory aroma to fill your kitchen, hinting at the delicious Roasted Boneless Leg of Lamb to come.

Step 5: Roast High
Begin by roasting the lamb at the high temperature for 15 minutes. Keep an eye on it as it cooks, looking for the surface to turn golden brown and fragrant. This high-heat roast will help develop a flavorful crust, crucial for the perfect Roasted Boneless Leg of Lamb that you and your guests will love.

Step 6: Roast Low
After the initial roasting, reduce the oven temperature to 350°F (177°C). Continue cooking the lamb until its internal temperature reaches 135°F for a medium-rare finish, which typically takes about 1 to 1.5 hours, depending on the size. Use an instant-read thermometer to monitor the temperature closely for perfect doneness of your Roasted Boneless Leg of Lamb.

Step 7: Rest and Slice
Once the lamb reaches the perfect temperature, remove it from the oven and allow it to rest for 15-30 minutes. This resting period is essential for the juices to redistribute throughout the meat. After resting, carefully remove the twine and slice the lamb thinly to reveal the juicy interior, ready to be served with your favorite sides.
