Australian-style lamb, or roast lamb, is an iconic dish of Australian cuisine,recognized as australia's national dish.

This choice was established by a national survey, highlighting Australians' attachment to authentic and convivial food.

But perhaps one of their favorite ways to prepare this tender meat is to roast it. This recipe is easy, and once you've tasted its wonderful flavor, you'll probably want to

make it a regular part of your meal rotation, perhaps with some mint sauce on the side, as Australians often do.

 

 

🌿🌟 The Recipe Steps

The shoulder used in this recipe contains more fat than the leg and therefore requires slower cooking.

If you've chosen to use a leg rather than a shoulder, cook for 20 to 30 minutes per pound, depending on your preference: rare, medium, or well-done.Serve this roast with a fresh salad and a light red wine.
