The anchovy technique isn’t just for lamb—it works beautifully with other red meats, too. Let’s get started on a roast that’ll have everyone asking for seconds.
Ingredients for jamie oliver roast leg of lamb anchovies
Sixteen ingredients, one unforgettable crust. Where umami meets precision for restaurant-quality lamb.
| Ingredient | Amount | Notes |
|---|---|---|
| Leg of Lamb 🐑 | 4 lb | Bone-in, frenched preferred |
| Anchovy Fillets 🐟 | 12 whole | High-quality, salt-packed |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High-quality, fruity |
| Garlic Cloves 🧄 | 8 cloves | Fresh, peeled, rough chopped |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Fresh Thyme 🌿 | ⅛ cup | Leaves only, finely chopped |
| Dijon Mustard 🍯 | 2 tbsp | High-quality, smooth |
| Honey 🍯 | 2 tbsp | Wildflower preferred |
| Red Wine Vinegar 🍷 | 2 tbsp | Dry, full-bodied |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Coarsely ground |
| Fresh Mint Leaves 🍃 | ½ cup | For garnish, finely chopped |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for basting |
The leg of lamb is the foundation, so choose bone-in, frenched if possible—it roasts more evenly and looks stunning. Whole Foods or specialty butchers carry the best cuts, often pre-fenched for convenience. Anchovies are non-negotiable here; high-quality salt-packed fillets (like Colosio or Cristal) make all the difference—they dissolve perfectly into the marinade. Fresh herbs should be vibrant, not wilted, and the olive oil should be extra-virgin with a peppery finish. The frenched cut also helps with presentation, making carving effortless for that showstopping platter.
No anchovies? Substitute with 1 tablespoon anchovy paste or a mix of soy sauce and fish sauce at half the amount. Fresh rosemary and thyme are ideal, but dried works at one-third the quantity if needed. The Dijon mustard should be smooth, not coarse—Maille is a reliable choice. For honey, wildflower or clover adds subtle floral notes that complement the lamb beautifully. The red wine vinegar should be dry; Bragg or Balsamic Glaze brands work well. If you’re short on time, pre-chop the garlic and herbs to speed up prep—just store them in a sealed container with a splash of olive oil to keep them fresh.
The lamb marinade keeps for 2 days in the fridge, sealed tightly. The roasted lamb itself reheats beautifully—just warm in a 325°F oven for 15-20 minutes covered with foil. For leftovers, store in an airtight container with any pan juices to keep it moist. The crust is best served immediately, but the meat stays tender for 3-4 days in the fridge. Freeze portions for up to 3 months—thaw overnight in the fridge before reheating. The mint garnish should be added just before serving to preserve its bright flavor.

Step-by-step instructions for Jamie Oliver's roast leg of lamb with anchovies
Here's how to create a perfectly juicy roast with a deep umami crust and tender pink centers.
Prepare the Anchovy-Herb Paste
In a food processor, combine the 12 whole anchovy fillets, 0.5 cup extra-virgin olive oil, 8 cloves rough chopped garlic, 0.25 cup finely chopped fresh rosemary, and 0.125 cup finely chopped fresh thyme. Process until you achieve a smooth, vibrant paste with no visible chunks. This blend forms the foundation of the umami-rich crust.
Transfer the paste to a small bowl and stir in the 2 tablespoons Dijon mustard, 2 tablespoons honey, and 2 tablespoons red wine vinegar. The mustard adds tangy depth while the honey and vinegar create a perfect balance of sweet and acid. Taste and adjust seasoning with the 1.5 teaspoons salt and 1 teaspoon freshly ground black pepper to your preference. This mixture should be vibrant, aromatic, and ready to transform your lamb.
Coat and Rest the Lamb
Pat the 4 lb leg of lamb completely dry with paper towels, ensuring no moisture remains on the surface. This step is crucial for developing that signature crispy crust. Using your hands, massage the anchovy-herb paste all over the lamb, including inside the cavity if it's been opened. Press firmly to ensure even coverage and penetration.
Place the lamb on a wire rack set inside a rimmed baking sheet, fat-side up. Cover with plastic wrap and refrigerate for at least 4 hours, preferably overnight. This resting period allows the flavors to deeply penetrate the meat while the surface dries out slightly, creating the perfect conditions for that umami-kissed crust when roasted.
Roast to Juicy Perfection
Preheat your oven to 325°F. Remove the lamb from the refrigerator and let it sit at room temperature for 30 minutes before roasting. This ensures even cooking throughout. Place the lamb in the preheated oven and roast for 2 hours 15 minutes, or until the internal temperature reaches 130°F for medium-rare. The meat should still have a slight resistance when pierced with a meat thermometer.
During the last 30 minutes of roasting, baste the lamb with melted 0.25 cup unsalted butter every 10 minutes. This basting creates a glossy finish and enhances the flavor. The lamb is ready when the crust is deeply caramelized and the internal temperature reaches your desired doneness. For medium-rare, aim for 130°F, and for medium, 140°F.
Rest and Garnish
Transfer the roasted lamb to a cutting board and tent loosely with aluminum foil. Let it rest for 20 minutes before carving. This resting period is essential for allowing the juices to redistribute throughout the meat, ensuring each slice remains succulent and flavorful. The lamb will continue to rise in temperature during this time, reaching a perfect medium-rare doneness.
While the lamb rests, finely chop the 0.5 cup fresh mint leaves. After carving the lamb into 1-inch thick slices, arrange them on a serving platter and sprinkle generously with the chopped mint. The fresh mint adds a bright contrast to the rich, umami flavors of the lamb. Serve immediately with your favorite sides to enjoy this restaurant-quality dish at home.
Pro Tips For Making Jamie Oliver Roast Leg Of Lamb Anchovies
- Sear the Lamb First: Hit that leg of lamb with a screaming-hot pan—no oil needed—before roasting. I used to skip this, thinking the oven would handle it, but that crispy crust from the sear locks in the anchovy-garlic flavor. Two minutes per side, and you’re golden.
- Crush Those Anchovies: Don’t just chop the anchovy fillets—mash them into a paste with the garlic and olive oil. That way, they melt evenly into the lamb instead of sinking to the bottom like little fish-shaped weights. (Yes, I’ve seen it happen.)
- Rosemary Sprigs, Not Chopped: Skewer whole rosemary sprigs into the lamb fat pockets—no need to mince. They’ll infuse the meat slowly and smell like a Provençal dream, while chopped rosemary just burns or slips away. (I learned this after a very sad, overly bitter first attempt.)
- Low-and-Slow Finish: After searing, crank the oven to 200°C (400°F) for 20 minutes, then drop to 160°C (325°F) until the internal temp hits 55°C (130°F). The high heat starts the crust, but the low finish keeps the meat juicy—no dry, overcooked lamb here. (Your meat thermometer is your best friend.)
Make-ahead tips for leftovers
Marinade Prep Ahead
The anchovy-herb marinade is the star of this dish, so I recommend making it 1-2 days in advance and storing it in an airtight container in the fridge. This gives the flavors time to meld together, deepening the umami profile.
When ready to use, simply massage it onto the lamb—no need to re-chop anything. The paste keeps its vibrant color and texture for up to 48 hours, making it perfect for stress-free meal prep. 💡
Lamb Prep Timeline
Plan your timeline carefully: After coating the lamb with marinade, it needs at least 4 hours (overnight is ideal) to rest in the fridge. I like to prep the marinade the night before, coat the lamb in the morning, and let it rest while I handle other dinner preparations.
This ensures the lamb is ready to roast when you’re ready to cook. Pro tip: Set a reminder on your phone for the 30-minute room temp step before roasting—it’s easy to forget! ⏰
Roasting Schedule
For a Sunday roast, I suggest starting the lamb in the oven around 12:30 PM (assuming a 2-hour 15-minute cook time). This gives you plenty of time to baste the lamb every 10 minutes during the last 30 minutes of cooking.
The basting step is critical—don’t skip it! If you’re short on time, you can baste every 15 minutes instead, though the flavor will be slightly less glossy. 🔥
Leftovers Strategy
This lamb reheats beautifully, so I always make extra for leftovers. Store the carved lamb in an airtight container with any pan juices to keep it moist. Reheat in a 325°F oven for 15-20 minutes until warmed through. The crust won’t be as crispy, but the meat stays incredibly tender.
For a quick fix, slice the lamb thinly and use it in sandwiches, grain bowls, or pasta dishes—the anchovy flavor adds a surprising depth to these meals. 💫
Freezing for Later
If you’re prepping for a future meal, freeze the whole roasted lamb (un-carved) in a freezer-safe bag for up to 3 months. Thaw it overnight in the fridge before reheating. The texture holds up well, though the crust may lose some crispness.
For best results, reheat the lamb in the oven at 325°F for 20-25 minutes, basting with a little olive oil or butter to restore some shine. ❄️
Make-Ahead Sides
To streamline your meal prep, make sides ahead of time. Roasted garlic potatoes can be prepped and stored in the fridge for 2 days, then reheated in the oven while the lamb rests.
Mint sauce can be made 1 day in advance and kept chilled—it actually tastes better after the flavors meld. This way, you only need to focus on the lamb when the time comes. 🌿
Nutrition facts
Frequently asked questions
Why do anchovies make the lamb crust so crispy?
The anchovies contain natural glutamates that break down proteins during the marinating process, creating a sticky, concentrated surface when roasted. This helps form a caramelized bark that locks in moisture while adding intense umami flavor. The saltiness also helps draw out surface moisture, which evaporates and contributes to that perfect crust.
Can I use this technique with other cuts of meat?
This anchovy marinade works beautifully with pork tenderloin, beef tenderloin, or even chicken thighs. For beef, reduce the marinating time to 2-3 hours since it's denser. The anchovy paste will create the same crispy crust while infusing deep savory notes. Try it with bone-in pork chops for extra flavor concentration.
What's the best way to store leftover lamb?
Store carved lamb in an airtight container with any pan juices to keep it moist. It stays fresh for 3-4 days in the fridge. For longer storage, freeze the whole roasted lamb (un-carved) in a freezer bag for up to 3 months. Thaw overnight in the fridge before reheating at 325°F for 20-25 minutes with a little olive oil or butter.
How do I adjust the recipe for a smaller or larger crowd?
For 4 servings, reduce to a 3 lb leg and halve all marinade ingredients. For 8 servings, use a 6 lb leg and increase marinade by 50%. Keep the same marinating time per pound of meat. The key is maintaining a 1:1 ratio of marinade to meat surface area for optimal flavor penetration.
Can I make the marinade without a food processor?
Yes! Mash the anchovies with a fork in a bowl, then mix in the olive oil, garlic, herbs, and other ingredients. Use a potato masher for a slightly chunkier texture. For the smoothest paste, transfer to a blender and pulse until combined. The texture will be slightly less refined, but the flavor remains identical.
