Slow cooking lamb is a great way to get tender, delicious meat. It only takes 2 easy steps!

Prepping your meat

  • Preheat oven to 140°C or 284°F (fan forced), then take the lamb out of the fridge and let it come back up to room temperature for 15-20 minutes. This will help your meat cook more evenly in the oven, instead of having some parts be undercooked while other parts are overcooked!
  • Drizzle lamb with oil and season it with salt, pepper, or a flavoursome rub. Give the lamb an herbal coating of fresh rosemary or dried oregano for best results!
  • If you want the most delicious lamb, then be sure to use a roasting dish that’s similar in size with your cut. You can place it on top of a bed of vegetable wedges or garlic cloves for extra flavor!

Long and slow cooking your lamb

  • Cover the roasting dish with a sheet of baking paper and foil to prevent moist from escaping. Remove them for the second half of cooking time so lamb browns nicely without getting overdone on the sides.
  • Cook the lamb for 4-8 hours, until it is extremely soft and tender. After about 2-4 hours of cooking time ( when you removed the foil and baking paper), start to pour some juice from your dish onto the meat every 30 minutes
  • Always remember when you remove the lamb from the oven, cover loosely with foil and rest for 10–20 minutes before serving.

Some additional slow cook lamb tips

Why letting your meat come to room temperature is important!

You should never cook any meat straight out of the fridge. Removing the lamb from your refrigerator and tempering it will create more evenly cooked, juicier results.

The idea is that a chilled piece of lamb takes longer to reach the proper internal temperatures. By the time it reaches its ideal temperature, you risk overcooking some areas which were closer to the surface.

Why you want to let your lamb rest after cooking?

A juicy steak, a flavorful chicken breast or even lamb chops can’t be made without the resting period. During this “resting fase” all those fibers relax and reabsorb any moisture they expelled during cooking. This will result in tender meat that’s moist on the inside with crispy browned edges on the outside.

If you cut into your lamb straight away, the juices would spill out onto the cutting board instead.

Why is your slow cooked lamb still tough?

It’s because you haven’t let the collagen break down. Extend the cook time, make sure there’s enough moisture in your roasting dish and keep your eyes on your precious meat of lamb!

Does Lamb get more tender the longer you cook it?

The type of meat you are cooking will dictate the optimal doneness. Lamb chops should be cooked until medium rare or else they’ll become tough.

A lamb shank on the other hand will become more tender with each minute of your cooking time as long as you don’t let your lamb dry out!

The cut of lamb should be on your mind when choosing your delicious meal for hungry guests.

Can you overcook slow cooked lamb?

When cooking lamb, it’s difficult to overcook the meat. You’ll know your lamb is ready when you can easily shredded with a fork and there should be no pink in the center.

Slow cookers make this task even easier by minimizing dry patches on each piece if exposed during cooking time.

To avoid tasting dried out or burnt bits, check periodically for doneness throughout slow-cooking periods and add more broth as needed after 2-3 hours into baking process

Why to use a thermometer when cooking lamb?

One of the hardest parts about cooking lamb is knowing when it’s finished. Even if you’re a professional chef or a backyard grill master there might be some hesitation in guessing how long to cook your cuts. It can get even more difficult with larger roasts like leg of lamb due to their size and cut.

That being said, there is one sure-thing that will give us an accurate reading on whether we should start slicing: using our trusty old meat thermometer!
