Tender and flavorful, this easy lamb shoulder roast melts in your mouth! It’s simple to prepare and, after a fast start, cooks long and slow in the oven. Time making this dish is mostly hands-off.
If you’ve been reading here a while, you know how much I adore Jamie Oliver. Since his young, baby-face days as the Naked Chef, I’ve watched his career expand as he grew up. Now with a family of his own, he has one of his son’s looking to follow in his footsteps, as he did with his own dad who ran the family pub kitchen.
While occasionally he does a fancy cheffy thing, a nod to his culinary training, most of his recipes are deliciously down-to-earth, like this one.
Easy Lamb Shoulder Roast
If you can’t find new potatoes or young carrots, substitute regular ones, peeled and cut into chunks. This recipe is adapted from one of Jamie Oliver’s in his book, Jamie at Home: Cook Your Way to the Good Life, published in 2006. I’ve been making some version of it ever since.
Ingredients
1 (2.2 lb or 1 kg) half shoulder of lamb
Fine sea salt and freshly ground black pepper
3-4 sprigs fresh rosemary
1 head garlic, peeled and large cloves halved
1 yellow onion, peeled and cut in thick slices
Olive oil
1 lb or 450g new potatoes
12 oz or 340g young carrots
Method
Preheat your oven as high as it goes, 450-500°F or 232-260°C.
Score the fat side of the lamb with a sharp knife.
Wrap it in cling film and set aside while you prep the garlic and onion according to the ingredient list.
Drizzle a little olive oil in the bottom of your Dutch oven and arrange the onion slices to cover the area where the lamb will rest. Put half of the garlic on top, along with half of the leaves from your rosemary, stripped from the sprigs.
Unwrap the lamb and lay it fat side up on the onion, garlic and rosemary. Drizzle the top of the lamb with more olive oil. Add on the balance of the garlic and stripped rosemary leaves with another little drizzle of oil.
Put the cover on the Dutch oven (or a tightly fitting piece of thick foil) and put it in the oven. Immediately turn the oven temperature down to 325°F or 163°C.
Roast for three hours. Meanwhile, scrub the new potatoes and young carrots and toss them with a little olive oil, salt and pepper. Set them aside, ready to go in.
When the three hours are up, remove the Dutch oven from the oven and take the lid off carefully, so you don’t burn yourself.
Add in the potatoes and carrots and turn them in the pan juices. Put the lid back on and roast for a further 30 minutes.
If you’d like a little more color on your lamb, baste it with the pan juices and pop it back in the oven without the lid for another 15-20 minutes or until it is colored to your satisfaction.
Remove the lamb to a serving platter with the potatoes and carrots.
Pan juices, along with the onion, garlic and rosemary, can be made into gravy with the addition of a little flour and stock or they can be served as is on the side.
