Jamie Oliver's 4 hour slow roast lamb a British recipe? ›

Get the lamb tray out of the fridge, rub the meat with a little olive oil, place in the oven, and turn the temperature down to 150ºC. Roast for 4 hours, or until tender, basting every hour with the tray juices and adding a splash of water each time. Remove from the oven and transfer the lamb to a serving platter.

This part of the animal works hard, so the meat from a lamb's shoulder is full of flavour. It takes a while to become tender, but this means it's a great choice for stewing and slow-roasting. To maximise the flavour, cook lamb shoulder on the bone so the meat simply falls apart when pulled with a fork.

Lamb should be roasted 20 mins per 450g/lb, plus an extra 20 mins. Weigh meat prior to roasting to determine cooking times. Cook at 220C/200C fan for the first 20 mins and then 190C/170C fan for the remaining time. Rest lamb before carving.

Cuts like the shoulder, shanks and forequarter are much more forgiving than a leg of lamb, and they can stay in the slow cooker for a couple more hours than the recommended cooking time. However, if you leave lamb in the slow cooker for too long it will become stringy and dry.

The leg and rack of lamb are perfect for herb-crusting and oven-roasting; since the shank and shoulder are a bit tougher, they fare well in stews or braises—the long cook time allows them to significantly break down and become fork-tender.

Season your lamb shoulder with rosemary and garlic, or even just a little salt and pepper. Sear the lamb shoulder in a hot pan to seal in the flavours if you wish, this is not compulsory however, slow cooking it as is works just as well.

And when you have a gorgeous cut, like a rack of lamb, you can cook it the good ol' Gordon Ramsay way—which is to say, lightly pan-sear it first, then baste it with an herby, garlicky butter, and finally finish it off in the oven until it's still pink and juicy in the middle. It comes out perfectly every time.

For a medium cooked lamb, which is perfectly pink on the inside, budget about 25 minutes per pound or until the internal temp registers somewhere around 130°F (about 1 ½ to 2 hours in a 325 degrees F-heated oven).

Use a meat thermometer to test whether your meat is cooked or not; it's not essential but will help determine to what stage the lamb is cooked, from rare (48–54˚C) to medium-rare (55–59 °C) to medium (60–66˚C) to well done (67–74˚C) and give a more consistent result. Roast lamb should be served pink in the middle.

Slow cooking in liquid transforms tougher cuts of lamb into fork-tender meat. Neck, shoulder and belly, either diced or as whole joints, are the best cuts for slow cooking and need to be cooked for at least 2 hrs at 150°C to soften the meat.

Is 4 hours on high the same as 8 hours on low? ›

The difference between "High" and "Low" on slow cookers seems to differ with every brand and model. One thing that is consistent, though, is that food takes seven to eight hours to reach a simmer point (around 210°) on low; versus three to four hours on high.

Lower temp = more succulent meat – Tough cuts like lamb shoulder need slow-cooking to tenderise them. The lower the roasting temperature, the less total moisture evaporation and thus juicier meat. 3-hour lamb is cooked at 180°C/350°F, while the 12 hour lamb is cooked at only 100°C/212°F.

Letting the lamb rest for at least 15 minutes once you finish cooking it is essential. This rest period allows the juices to redistribute and settle throughout the muscle fibers, which creates a tender and juicy piece of meat. The juices will escape if you cut into the lamb right away, causing the meat to dry.

For the perfect roast lamb, we recommend seasoning the surface of the meat, and then searing it, especially fat side down in a pan before roasting. Why bother with searing? Contrary to some stories, searing is less about locking in moisture, and all about improving the flavour!

Lamb loin roast is best prepared using dry heat cooking methods such as roasting, grilling, or broiling. Cook lamb loin with care, as it can dry out easily if overcooked. Other cooking methods for lamb loin roast include brushing the loin with oil and sprinkling it with salt and pepper before grilling or broiling.

Baking soda / bi-carb and cornflour/cornstarch are the secret ingredients that tenderise the lamb meat. It's a technique called “velveting” that is used by Chinese restaurants, and it's the reason why the meat in your favourite Chinese dishes are always so soft.

Cuts of lamb that are popular for slow cooking include the shoulder, leg, forequarter, shanks, neck chops, lamb ribs, and some sausages. These cuts are usually tougher because they have lots of connective tissue and fats, but this makes them perfect for slow and low methods of cooking.

Loin. This is the most tender part of the lamb, producing only the most tender and flavourful cuts. Boned and rolled loin makes for a delectable roasting joint. This is also where the juiciest chops and noisettes come from.

The leg and rack are the most tender cuts of meat on a lamb, and are at their best when roasted. Roasting is a "dry heat" cooking method, meaning that you do not add any liquid to the meat as you cook it.

The shoulder has a higher fat content, is richer in flavor and is less expensive than the lamb leg. Because of the higher fat content, it is also more forgiving and stays juicier.
