I cut some slits in lamb and put in pealed garlic cloves and in other slits rosemary paste (tubes in vegi section of coles)

I then add some salt and pepper and small amount of olive oil to skin and roast in oven on 220 degrees for 20 mins then on 180 degrees for about 2 hrs for just under 2kg.

Roast with potatoes, sweet potatoe, onion and what other vegies you want.
