Ingredients Needed
Before diving into the recipe, let’s take a look at the ingredients. Here’s what you’ll need:
- Leg of lamb (bone-in, about 2 kg)
- Garlic (8 cloves, smashed)
- Rosemary (fresh sprigs, around 4-5)
- Olive oil (for rubbing)
- Lemon (2, zested and halved)
- Sea salt (to taste)
- Black pepper (freshly ground)
- Balsamic vinegar (1-2 tbsp, optional for depth of flavor)
- Carrots (2, peeled and chopped)
- Onion (1 large, chopped)
- Cinnamon stick (1, optional for a bit of warmth)
- Red wine (1 cup, to make the pan sauce)
- Stock (beef or lamb, about 500ml)
How To Make Jamie Oliver’s Slow Roast Leg Of Lamb
Step 1: Prepare The Lamb
Start by preheating your oven to 160°C (320°F). Pat the lamb dry with paper towels to ensure you get a nice crust. Then, rub the lamb with olive oil, garlic, and rosemary. Season generously with sea salt and black pepper. Squeeze one lemon over the lamb and rub the zest into the meat. The citrus will bring out a fresh, bright flavor that cuts through the richness of the lamb.
Step 2: Set Up The Roasting Pan
In a roasting pan, place the chopped onions, carrots, and cinnamon stick (if using). They’ll form a flavor base for the lamb to sit on. The vegetables will also catch all the delicious drippings, making them sweet and caramelized.
Step 3: Roast Low And Slow
Place the lamb on top of the vegetable bed. Transfer it to the preheated oven and roast for 2.5 to 3 hours, depending on the size of the leg. During the roasting process, you’ll want to baste the lamb every 30 minutes with the pan juices, ensuring the meat stays juicy and develops a gorgeous golden-brown crust.
Step 4: Make The Sauce
Once the lamb is cooked to perfection, remove it from the oven and rest it on a plate. Use the pan drippings to make a sauce by adding red wine and stock. Scrape up any bits stuck to the pan, and let the sauce simmer for about 10 minutes until it thickens slightly.
Step 5: Serve And Enjoy
Carve the lamb and drizzle with the pan sauce. For added zest, squeeze the remaining lemon half over the lamb before serving.
Ingredient Science Spotlight
Each ingredient in Jamie Oliver’s Slow Roast Leg of Lamb recipe serves a specific purpose in enhancing the overall flavor and texture of the dish. Here’s a breakdown:
- Garlic: Garlic’s natural sugars caramelize during roasting, adding a savory sweetness that balances the lamb’s richness.
- Rosemary: This herb has a robust pine-like flavor that’s perfect for hearty meats like lamb. Rosemary also has anti-inflammatory properties.
- Lemon: The acidity in lemon helps tenderize the meat while providing a refreshing contrast to the deep, savory flavors of the lamb.
- Cinnamon: Though an optional ingredient, cinnamon adds a warm, aromatic touch. It’s particularly effective in rounding out the savory and sweet components of the dish.
- Red Wine: The wine’s acidity helps cut through the fat of the lamb, while the alcohol evaporates, leaving behind complex flavors that enrich the sauce.
- Carrots and Onion: These vegetables act as flavor carriers, absorbing the lamb’s juices and giving you a naturally sweet and savory base for the sauce.
Expert Tips
- Rest the Meat: Let your lamb rest for at least 15 minutes before carving. This helps the juices redistribute throughout the meat, making it extra juicy.
- Use a Meat Thermometer: If you’re unsure when the lamb is done, a meat thermometer is a game-changer. Aim for an internal temperature of 55-60°C (130-140°F) for medium-rare.
- Crisp the Skin: For extra crispiness on the skin, increase the oven temperature to 220°C (425°F) for the last 20 minutes of cooking. This gives the lamb a perfect golden-brown crust.
- Marinate: For more flavor, marinate the lamb overnight with the garlic, rosemary, and lemon before roasting. The longer the meat sits with the marinade, the more intense the flavors will be.
- Don’t Skip the Basting: Basting every 30 minutes keeps the lamb moist and helps build layers of flavor.
Recipe Variations
- Herb Blend: If you don’t have rosemary, try thyme, oregano, or even sage. They each bring their own nuance of flavor to the dish.
- Spices: For a more adventurous take, add cumin, smoked paprika, or a pinch of cayenne pepper. These spices bring warmth and depth.
- Vegetables: Toss in parsnips, sweet potatoes, or even beets with the carrots and onions for an interesting twist.
- Fruit: Add dried fruits like apricots or raisins to the pan in the last 30 minutes of roasting. The sweetness pairs beautifully with the richness of the lamb.
