Few culinary traditions are more treasured in Britain than the Sunday roast. It's a meal that's indicative of comfort, family, and a slow, satisfying way to end the week. Beef and chicken have their moments, but a properly roasted joint of lamb – golden-crispy skin and tender, flavourful meat – is frequently the undisputed centrepiece of a genuinely intimate celebration.
But picking the perfect cut isn't always easy. The classic leg of lamb is iconic for a reason, but the world of lamb roasting is much fuller and more varied than a single cut. Our butchers work with these amazing animals each day, and we know that the various joints have specific textures and flavours. Choosing organic, pasture-fed lamb takes it one step further. This guide will go through some of the best cuts of lamb for your next Sunday roast, to guarantee a perfect meal.
Beyond the Leg: Exploring Shoulder, Rack, and Breast for Roasting
While a leg of lamb is a go-to for many, knowing the other types of cuts available could open up new culinary possibilities. Every joint has its own personality and preferred cooking style.
The Classic: Leg of Lamb
This is the archetypal roasting joint. It's lean, easy to carve, and provides a huge variety of meat to go with it. A bone-in leg adds more flavour because the marrow and connective tissue fill up the meat in cooking, while the bone itself further facilitates an even spread of heat. A boneless leg is simpler to carve and can be filled with herbs and garlic for greater flavour. There's little that can go wrong with your roast when it comes to the leg.
The Butcher's Favourite: Shoulder of Lamb
When you ask a butcher what the best choice between cuts of lamb for a slow roast is, many will answer that it's shoulder. This joint has done more work than the leg, which results in greater connective tissue and intramuscular fat (marbling). It's not a bad thing: It's the flavour we need to unlock!
The shoulder may take longer and require more slow cooking, but the reward will come with delicious, moist meat that just falls off the bone. It's great for an easy Sunday, where two forks will pull the meat apart and give you rich, natural juices to go with it.
The Elegant Showstopper: Rack of Lamb
The rack of lamb is the ultimate showstopper for a gathering. This is the lamb equivalent of a beef rib-eye, prized for its ultimate tenderness and delicate flavour. Usually, 'French trimmed' by a butcher, where the bones are cleaned of excess fat and meat, it looks amazing on a plate. A rack cooks far faster than a leg or shoulder, and it's usually best served pink. With a beautiful look and low cooking time, it's perfect for a special occasion dinner party.
The Economical Hero: Breast of Lamb
Often overlooked, the breast is a surprisingly cost-effective and flavourful cut. It has many layers of fat and meat, and when properly prepared, it's a triumph. The way to roast a breast is to get your butcher to debone it, allowing you to fill in a delicious filling for it (breadcrumbs, lemon zest and herbs, for instance) and roll it into a tight joint. Roasting slowly, the fat renders down, the meat and stuffing basted away until the exterior is crispy with a moist, tasty inside.
The Impact of a Grass-Fed Diet on Lamb's Flavour Profile
The difference between a standard supermarket lamb and a certified organic lamb that's 100% pasture-fed is profound, and you can taste it in every bite. When lambs grow on a good, all-natural diet made up of grasses, wildflowers and herbs, their flavour profile becomes significantly more complex and even nuanced compared to a grain-fed lamb. This diverse diet manifests itself in subtle, herbaceous notes within the meat as well. The flavour is clean, sweet, and 'lamby' without being overpowering.
The fat, too, is different. In grass-fed animals, fat is sometimes slightly yellower due to beta-carotene in the fresh grass, and also contains a large amount of beneficial omega-3 fatty acids. Roasting a joint of organic, pasture-fed lamb, this higher-quality fat liquefies, naturally basting the meat and giving it a rich, real flavour that isn't imitable. It's the taste of an animal that has lived a healthy, natural life.
Butcher's Top Tip: Preparing and Scoring the Joint for Optimal Tenderness
When it comes to getting your roast right, it's all about prepping. A couple of quick tweaks before the joint even enters the oven will ensure a crispy skin and juicy meat that's evenly cooked.
Bring it to Room Temperature: Remove the lamb from the fridge and keep it at room temperature for at least one hour before cooking. Positioning a cold joint directly in the hot oven will cause the muscle fibres to stiffen and lead to unequal cooking.
Pat the Skin Dry: A paper towel should be used to thoroughly pat the complete joint surface (especially the fatty surface) until it is completely dry. Moisture is the enemy of crispy skin.
Score the Fat: With a very sharp knife, cut in a diamond pattern through the fat cap. Watch to avoid digging into the meat itself. This one simple thing brings three major benefits: it aids the fat in rendering down a little better, giving a kind of self-basting effect, it lets your seasonings reach deeper, and it results in a crispy golden-brown crackling.
Perfect Pairings: Herbs and Sides to Complement Organic Lamb's Richness
The strong and sweet flavour of organic lamb is great paired with so many timeless ingredients.
Herbs and Aromatics: The holy trinity for lamb is garlic, rosemary, and thyme. With the tip of a knife, cut into the meat and stick little slivers of garlic and sprigs of fresh rosemary. Rub the joint with olive oil, sea salt, freshly ground black pepper and chopped thyme before turning it into a roast.
The Sauce: For many, classic mint sauce is a must-have, the sharp freshness cutting the rich flavour and texture of lamb. For a thoroughly mouthwatering gravy, deglaze the roasting pan with a dash of wine or stock, scraping out all those caramelised bits sitting at the bottom of the pan.
Sides: Crispy roast potatoes are excellent – and lamb fat is best for cooking them in. Roasted root vegetables such as carrots and parsnips, which sweeten in the oven, are a great accompaniment. To end, have something green and fresh – steamed spring greens or buttered peas, for example – to balance out the plate.
