This easy Provençal lamb is a fragrant and sophisticated take on a classic roast. By marinating a bone-in leg of lamb with a pungent mixture of Dijon mustard, fresh rosemary, and balsamic vinegar, the meat develops a deeply savoury crust that contrasts beautifully with its tender, juicy interior. The addition of ripe tomatoes and sliced Spanish onions creates a natural sauce in the roasting tin, enriched by the golden sweetness of honey and the earthy aroma of woody herbs.
A fantastic choice for a high-protein main course, this dish is simple enough for a weekend family gathering yet elegant enough for a formal dinner party. Serving the lamb with its own slow-roasted tomatoes and pan juices ensures every slice is infused with Mediterranean flavour. Pair it with steamed seasonal greens or crushed new potatoes for a complete, nutritious meal that captures the essence of the French countryside.

Ingredients for Easy Provençal Lamb
1 (6- to 7-pound) bone-in leg of lamb, trimmed and tied
80g Dijon mustard
3 tablespoons chopped garlic (9 cloves), divided
1 tablespoon chopped fresh rosemary leaves
1 tablespoon balsamic vinegar
Kosher salt and freshly ground black pepper
1.4kg ripe red tomatoes, cored and 1-inch diced
120ml good olive oil
120ml good honey , divided
1 large Spanish onion, sliced
4 sprigs fresh thyme
2 sprigs fresh rosemary
Note: You'll want to use a liquid—rather than a solid—honey for this recipe so it can be drizzled on the lamb.
How to make Easy Provençal Lamb
Back to contentsPreheat the oven to 450 degrees.
Place the leg of lamb in a large roasting pan fat side up and pat it dry with paper towels. Combine the mustard, 1 tablespoon of garlic, the rosemary, balsamic vinegar, 1 tablespoon salt and 1/2 teaspoons of pepper in a mini food processor and pulse until the garlic and rosemary are minced. Spread the mixture on the lamb.
Place the tomatoes, olive oil, 60ml the honey, the onion, the remaining 1 tablespoon garlic, 2 tablespoons salt, and 2 teaspoons pepper in a bowl and toss well. Pour the tomato mixture around the lamb and tuck in the thyme and rosemary sprigs. Drizzle the lamb with the remaining 60ml honey.
Roast for 20 minutes. Turn the heat down to 350 degrees and roast for another 1 to 1 1/4 hours, until a meat thermometer registers 130 to 135 degrees for medium-rare. Place the lamb on a cutting board, cover with aluminum foil, and allow to rest for 15 minutes. Discard the herb stems and return the tomatoes to the oven to keep warm. Slice the lamb, arrange on a platter, sprinkle with salt and pepper, and serve with the tomatoes and pan juices spooned on top.
