Roast lamb with fetta and olive dressing is a Greek inspired roast with a medley of traditional Greek flavours using garlic, oregano, lemon, feta and black olives. Firstly the lamb is marinated with a rub made with garlic, oregano, red wine vinegar, lemon juice and olive oil. Smother the underside of the lamb with this heady mixture and allow it to marinate for an hour or so.

Next up we roast the lamb firstly on high heat to start to render the lamb fat then lower the heat adding some halved waxy kipfler potatoes to soak up the pan juices and continue to cook the lamb to our desired doneness. We particularly like lamb that still has a ‘blush’ to each slice so we cooked ours until it was 55c (140f). We’ve given cooking times and temperatures below if you’d like your lamb a lot pinker, or more well done.

Lamb – Our American Friends Need To Catch On

Australians love lamb – that’s no secret. Whether its for a Sunday roast, or lamb sausages and lamb chops on the barbie for Australia Day, we devour its rich, buttery and delicate texture like no one else. There was even a popular ad on television where Naomi Watts turned down a date with Tom Cruise saying “nothing comes before a roast lamb dinner”!

Australians consume around 9kg (20 pounds) of lamb per person each year, whereby Americans eat roughly only 2kg (5 pounds) each so they really need to up their lamb consumption and introduce new recipes for family and friends so the word spreads that eating lamb is ‘bloody delicious’!

Let’s Get Started – Make The Rub And Do Some Rubbing!

How to Choose Lamb Shoulder

Look for lamb shoulder that has generous fat marbling which renders and keeps the meat juicy and the flavour intense. Shoulder meat should be pink with a layer of firm, creamy white fat. Lamb shoulder is invariably cheaper than leg of lamb, and for our money it’s lamb shoulder over leg, every time.


Marinades add a gigantic flavour to meat. They also add moisture, particularly when the marinade contains oil as its an effective way to add extra moisture into the meat.

Marinating the meat with a rub of aromatics and oil allows the meat to take on the marinade flavours. When the meat is cooking juices are released along with the marinade and this is what gives the potatoes a glorious flavour.

Because this marinade contains acid in the form of lemon juice and vinegar we don’t advocate marinading overnight. The acids will start to break down the meat leaving you with a grey, almost cooked meat and we don’t want that!

Ready To Cook

Lamb Shoulder Cooking Times

Whether you’re roasting lamb, beef or pork the most reliable way to take the guess work out of your desired doneness is to invest in a meat thermometer. They’re available everywhere and you only need to spend around $20 to insure that your meat is served exactly how you like it.

When your at the right temperature remove the roast from the oven and allow it to rest for 10-15 minutes to allow the juices to redistribute through the meat and be reabsorbed.

Time To Make The Fetta And Olive Dressing

As you can see below the temperature of the lamb continues to rise while it is resting.

Core Cooking Times Using a Meat Thermometer

Rare 48-50c (118f-122f), rested temp 52c-54c (125f-129f)

Medium Rare 52c-54c (125f-129f), rested temp 56c-58c (133f-136f)

Medium 56c-58c (133f-136f), rested temp 60c-62c (140f-144f)

Well Done 65c-68c (149f-155f), rested temp 70c-75c (158f-167f)

If you don’t have a meat thermometer cook the roast for 20 minutes per 500g (1.1 pounds)
