Notes

1. LAMB CUT: This recipe can be made with a leg or shoulder of lamb. Shoulder has more fat running through it than leg, so you can actually roast it uncovered (here’s my Slow Roasted Lamb Shoulder recipe), but this recipe will also work with shoulder. This recipe is designed for lamb leg because it’s leaner, so it benefits greatly from slow roasting partially submerged in liquid so it doesn’t dry out. Cooking it this way also infuses it with flavour.

2. The upper side of the lamb leg has more meat so we want to roast that partially submerged in the liquid for most of the cooking time. The upper side of the lamb is rounder and usually has more fat. The underside has less fat and is more flat.

3. TRY THIS WITHTruly Crunchy Roast Potatoes!

4. MORE ROAST LAMB: Ultra Tender Slow Cooker Roast Lamb, Slow Roasted Lamb Shoulder, Classic Roast Lamb with Gravy (i.e. it’s blushing pink inside) and Slow Roasted GREEK Leg of Lamb (delish lemon garlic flavours!).

5. Roasting Times (this cook method is pretty forgiving so round up to determine cook time eg if your lamb is 1.8kg, use the 2 kg cook times):

6. Calories in the nutrition are higher than actual because I do not know how to adjust for the fat that is skimmed off the liquid before making the gravy. I usually throw out about 1/3 cup which means the calories is probably closer to 500 calories per serving, and that’s assuming all the gravy is consumed.
