Top tips for the perfect roast lamb

No matter whether you're a lamb-roast veteran or just trying it for the first time, it's always a special meal.
 
In winter it's so comforting, in spring it's abundant (and therefore extra affordable) and who could go the summer without a rack of lamb chops?
 
Roasting lamb might seem intimidating, but once you know the temperatures and times the oven does most of the work for you.
 

How to roast lamb

What lamb cuts are best for roasting

The leg and rack are the most tender cuts of meat on a lamb, and are great for a standard roast. A roast rack of lamb needs much less time to cook than a roast leg.

Some general cooking time and temperatures:

  • Rack of lamb: Pre-sear it in a pan to get it brown all over, then roast for 10-25 minutes at 220°C, depending on your doneness preference

  • Leg of lamb: 20-30 minutes per 500g at 180°C

Lamb is best when served rare to medium. If you have a thermometer, it's rare at 60°C, medium-rare at 60-65°C, and medium at 65-70°C.

Cuts such as shanks and shoulders (with more connective tissue) are better for slow-roasting, braising and stewing.
 
 

How to prepare your lamb

Score the fat of the lamb roast with a small, sharp knife. This will help the fat render out and create a nice crisp and browned surface.
 
Marinate your lamb overnight or for at least 30 minutes. Some popular flavour combinations are:
 
  • Lemon, garlic and rosemary
     
  • Paprika, cumin and coriander
     
  • Indian spices - e.g. Korma sauce
Take your lamb out of the fridge 15-20 minutes before cooking. This will help it cook nice and evenly.
 
 

What to roast lamb in

Ensure your roasting pan or dish has high enough sides to catch any juices.
 
Use a roasting dish that is close to the size of the lamb. This way the pan juices won’t burn and give a bitter taste to the roast.
 
Use a roasting rack if you have one. This ensures even browning and heat circulation around the meat.

Baste the roast with its own juices as it cooks to keep it juicy and give it extra flavour. Spoon the juices over the top of the meat every 20-30 minutes. 

 
 

How to serve your roast

Always rest your meat before cutting. Remove it from the oven, place a foil tent loosely over it, and leave it for 15-20 minutes. A well-rested piece of meat will be more tender and juicy.
 
Cut the meat across the grain so that it's tender when you eat it.
