Tips / Notes for Best Results

  • Let the Lamb Rest Before Cooking: Take the lamb out of the fridge and let it come to room temperature. This helps it cook evenly and stay juicy.
  • Season Well for Deep Flavor: Rub the lamb with herbs, garlic, salt, and spices. Let it sit for a while so the flavors go inside the meat.
  • Roast at the Right Temperature: Cook the lamb in a hot oven first to lock in juices, then lower the heat so it cooks slowly and stays tender.
  • Don’t Waste the Pan Juices: Use the drippings from the roasting pan to make the gravy. It adds a rich flavor and makes the sauce taste amazing.

Oven-Roasted Boneless Leg of Lamb with Pan Gravy

By Tiffany Boakye-Korsah
Prep time: 20 minutes
Cook time: 1 hour 15 minutes
Servings: 5-6

Ingredients

FOR THE LAMB ROAST:

  • - 4.3 lbs boneless leg of lamb, cut into 4 pieces
  • - 8 cloves garlic, grated
  • - 1 small fresh onion, grated (about 1.5 Tbsp)
  • - 1 tsp fresh ginger, grated
  • - 2 tsp ground coriander
  • - 2 tsp ground cumin
  • - 1/2 tsp all spice
  • - 2 tsp dried thyme
  • - ½ tsp red pepper flakes
  • - ½ tsp black pepper
  • - 4 tsp kosher salt
  • - 3 tbsp olive oil
  • - 1 small onion for roasting, quartered

FOR THE PAN GRAVY:

  • - All pan drippings – roasted onion pieces and juices from the roasting pan
  • - 3 tbsp unsalted butter
  • - 1–2 tsp olive oil
  • - Warm water – as needed to adjust consistency
  • - Beef bouillon – to taste

Instructions

Prep the Lamb: Clean the lamb and pat it dry. Mix garlic, onion, ginger, coriander, cumin, allspice, thyme, chili flakes, black pepper, salt, and olive oil into a thick paste. Rub it all over the lamb so it’s fully coated. Let it marinate for at least 1 hour or overnight for best flavor.

Preheat the Oven: Set your oven to broil at 450°F. Place quartered onions in a roasting pan, then set a rack on top (or use the onions as a base). Lightly oil the rack and place the lamb pieces on top with space between them.

Broil the Lamb: Broil for about 20–30 minutes, until the internal temperature reaches 130°F for medium-rare or around 140°F for medium. Use a meat thermometer to avoid overcooking. The lamb should be juicy, not dry.

Rest the Lamb: Take the lamb out and loosely cover it with foil. Let it rest for 10–15 minutes so the juices settle and the meat stays tender and juicy when cut.

Prepare the Pan Gravy: Blend the pan drippings and roasted onions until smooth. In a pan, melt butter, add flour, and whisk into a smooth paste. Slowly add the blended mixture while whisking. Stir in olive oil, adjust thickness with water, and season with beef bouillon.

Serve: Serve the lamb hot with the gravy drizzled on top or on the side. It goes great with mashed potatoes, roasted potatoes, and fresh green vegetables.

Notes
