Lamb Pot Roast with Oranges and Olives

This slow-cooked lamb pot roast with oranges and olives is a fragrant and sophisticated dairy-free main course. The combination of succulent lamb shoulder, zesty citrus and briny black olives creates a rich, complex flavour profile that develops beautifully during the long braising process. By roasting the meat first and then simmering it in a tarragon-infused red wine and tomato base, you achieve a perfectly tender texture that yields easily to a fork.

Ideal for a relaxed Sunday lunch or a dinner party, this heart-healthy lamb dish can be prepared well in advance. Seasoning the meat the day before ensures the aromatics penetrate deeply, while the resting period after cooking guarantees a juicy finish. Serve this Mediterranean-inspired roast with seasonal greens or roasted root vegetables for a truly comforting homemade meal.

How to make Lamb Pot Roast with Oranges and Olives

Holding knife parallel to work surface, cut lamb lengthwise, following seam where bone was removed and stopping about 1/2" before you get all the way through. Open lamb like a book and season all over with salt and pepper. Close, wrap tightly in plastic, and chill at least 8 hours.

Preheat oven to 204°C. Open lamb and arrange garlic on bottom half, leaving a 1" border. Top with orange slices and olives. Sprinkle with savory and red pepper flakes. Close lamb and tie at 1" intervals with kitchen twine.

Place lamb on a wire rack set inside a large rimmed baking sheet. Roast until nicely browned, 30–40 minutes. Remove lamb from oven.

Reduce oven temperature to 149°C. Carefully transfer lamb to a large heavy ovenproof pot and add stock, wine, and tomato purée. Cover and braise lamb, basting with braising liquid every 30 minutes, until golden brown and fork-tender, 2 1/2–3 hours. Season with salt and pepper, if needed.

Transfer lamb to a cutting board and let rest at least 30 minutes before slicing. Serve with braising liquid.

DO AHEAD: Lamb can be seasoned 1 day ahead; keep chilled. Lamb can be braised 2 days ahead; cover and chill.
