Tender and deeply savory, Roast Lamb with Anchovies turns a classic leg of lamb into a slow-cooked centerpiece with bold Mediterranean-inspired flavor. Lemon, garlic, parsley, and anchovy melt into the meat as it roasts, giving you a rich, reliable main dish that feels special yet cooks mostly hands-off.
This is the kind of meal that works beautifully for a family lunch, a relaxed holiday table, or any time you want a roast that feels generous without being fussy. The long, covered cooking time keeps the lamb succulent, while the final blast of heat gives it that inviting browned finish.
What makes this dish so satisfying is the way the anchovies season the lamb without making it taste fishy. They simply deepen the savoriness, while the lemon keeps everything bright and balanced.
You also get flexibility built in. Add baby potatoes to the roasting tin for an effortless side, or serve the carved lamb with your favorite vegetables, bread, or salad and let the pan juices do the rest.
What You Need to Make This Roast Lamb with Anchovies
Leg of lamb — the star of the dish, ideal for slow roasting until tender and flavorful.
Oil-packed anchovies — bring deep savory richness and melt right into the seasoning paste.
Garlic — adds warmth and punch that pairs beautifully with rich lamb.
Fresh parsley — lifts the roast with a clean, herbal note.
Lemon zest and juice — brighten the meat and balance the richness of the lamb and anchovies.
Extra-virgin olive oil — used at the end to help the exterior brown and develop color.
Salt and black pepper — round out the seasoning and sharpen the flavor of the herb mixture.
Baby potatoes — optional, but excellent for soaking up the roasting juices in the pan.
Water — keeps the roasting environment moist and helps prevent the pan from drying out during the long oven time.
Cooking Steps
STEP 1: Heat your oven to a low temperature and make the anchovy mixture first. Blend or crush the anchovies with their oil, garlic, chopped parsley, lemon zest, lemon juice, salt, and black pepper until you have a rough, intensely aromatic paste.
STEP 2: Set the lamb in a snug roasting tin and cut several deep slits across the surface. These cuts help the seasoning work its way into the meat instead of sitting only on the outside.
STEP 3: Rub the anchovy mixture all over the lamb, pressing it into every cut and crevice. This is where the roast gets its signature flavor, so take a moment to coat it thoroughly.
STEP 4: Add a little water to the base of the tin, then cover the lamb tightly with foil. Roast it slowly for about 4 hours, spooning the juices over the meat from time to time so it stays moist and well seasoned.
STEP 5: If you want potatoes, add them during the last hour of cooking. Turn them well in the juices so they soften gently and pick up all that rich lemony, garlicky flavor from the pan.
STEP 6: For the final stretch, uncover the lamb, drizzle it with olive oil, and raise the oven temperature. This gives the outside a deeper golden color and a more roasted finish while the inside stays tender.
STEP 7: Let the lamb rest for 5 to 10 minutes before carving. That short rest helps the juices settle back into the meat, making each slice more succulent when you serve it.
Helpful Tips
- Choose a roasting tin that fits the lamb fairly closely so the juices stay concentrated and do not spread too thinly across the pan.
- Do not skip cutting slits in the meat, because that is what helps the anchovy, lemon, and garlic mixture season the lamb all the way through.
- If the pan looks dry at any point during the long roast, add a small splash of water so the juices do not scorch.
Can you taste the anchovies in the finished lamb?
Not in a strong or obvious way. Anchovies mostly melt into the roast and act like a savory seasoning, adding depth and complexity rather than a distinct fish flavor.
What size leg of lamb works for this method?
A leg between 4 and 9 pounds works well, which makes this a flexible option for smaller family meals or larger gatherings. Just make sure your roasting tin holds it snugly and your oven has enough space.
Do the potatoes need to be parboiled first?
No, they can go straight into the roasting tin during the last hour. Because they cook in the hot juices and steam under the residual heat, they become tender and richly flavored without an extra step.
Can I prepare the lamb ahead of time?
Yes. You can make the anchovy mixture and rub it onto the lamb several hours ahead, then refrigerate it covered. Bring it out while the oven heats so it loses a bit of its chill before roasting.
Perfect Pairings
This lamb is especially good with a crisp green salad dressed simply with lemon or vinegar. The freshness cuts through the richness of the roast and keeps the plate balanced.
Warm bread is another excellent choice, especially if you want something to soak up the pan juices. A rustic loaf or soft flatbread both work beautifully alongside the carved meat.
If you are skipping the potatoes in the roasting tin, serve the lamb with roasted vegetables or a creamy mash. Something mild and comforting lets the bold lamb flavors stay front and center.
How to Store & Reheat
Leftover lamb keeps well in the refrigerator for up to 3 days when stored in an airtight container with a little of the pan juice to help prevent it from drying out. Store any potatoes separately if possible so they keep their texture better.
For longer storage, freeze sliced or shredded lamb for up to 2 months. Wrap it well and include a bit of the cooking liquid if you can, since that helps protect the meat from drying during reheating.
To reheat, place the lamb in a covered baking dish with a spoonful or two of juices or water and warm it gently in the oven until heated through. You can also reheat smaller portions on the stove over low heat. Avoid high heat, which can make the meat firm instead of tender.
Roast Lamb with Anchovies
Ingredients
- 1 leg of lamb 4–9 lb
- 1 can oil-packed anchovies 3 oz, including the oil
- 4 garlic cloves finely crushed or pressed
- 3 tablespoons freshly chopped parsley
- 1 lemon zested and juiced
- 1/4 cup extra-virgin olive oil
- Salt to taste
- Black pepper to taste
- Baby potatoes as desired, halved if large
- About 1 cup water for the roasting tin
Instructions
- Preheat the oven to 130ºC/270ºF.
- In a mortar and pestle or a blender, combine the anchovies with their oil, the lemon zest, lemon juice, garlic, parsley, salt, and pepper. Process until the mixture is roughly blended and well combined.
- Set the lamb in a roasting tin that holds it fairly snugly. Using a sharp knife, cut several deep slits across the meat.
- Spread the anchovy mixture all over the lamb, pressing it well into the cuts so the seasoning can penetrate the meat during roasting.
- Pour about 1 cup of water into the base of the roasting tin. Cover the lamb tightly with foil, then transfer the tin to the oven and roast for 4 hours, basting the meat roughly every 30 minutes.
- For the optional potatoes, add them to the roasting tin when 1 hour of cooking time remains. Turn them through the pan juices so they cook gently alongside the lamb until tender.
- For the final 30 minutes of cooking, remove the foil. Drizzle the olive oil over the lamb and raise the oven temperature to 200ºC/400ºF to brown the surface and develop a well-colored crust.
- Once cooked, remove the lamb from the oven and let it rest for several minutes before carving. Serve with the potatoes and the pan juices.
