Some recipes don't just feed a table — they stop the room. The moment I carried this gigot d'agneau out of the oven last Easter Sunday, golden and crackling and perfumed with garlic and rosemary, my entire family went quiet for a beat before erupting into the kind of noise that only happens when food looks *that* good. My mother-in-law, who grew up outside of Lyon and has opinions about everything French, set down her wine glass and said, 'Oui. C'est ça.' That was the only review I needed.
The French have been roasting leg of lamb for Easter since medieval times, and honestly, if something isn't broken after eight centuries, you don't fix it. What makes the French approach — the *gigot d'agneau* — different from your average Easter roast is the technique: deep garlic-anchovy larding that melts invisibly into the meat, a high-heat sear followed by a gentler finish, and resting the lamb long enough for every last drop of juice to settle back into the fibers. The result is a roast that's blush-pink and impossibly juicy at the center with a crust that shatters like glass. And because no French Sunday dinner is complete without potatoes cooked in something wonderful, we're doing proper pommes frites — twice-fried in the rendered lamb drippings — which is an act of genius the French have been quietly perfecting forever.
This is the Easter main course for the year you decide to do it properly. It's not fussy in the way that requires professional equipment or culinary school — it just requires your attention and a little patience, both of which are absolutely worth it on a Sunday this special. If you're planning a full French Easter spread, our Classic French Pain Perdu (Spring Brioche French Toast with Lemon Curd & Fresh Strawberries) makes a stunning brunch starter before the big roast dinner — consider it the amuse-bouche of your entire holiday weekend.
📋 French Easter Leg of Lamb (Gigot d'Agneau) with Crispy Pommes Frites
5–6 lbs bone-in leg of lamb, trimmed of excess fat
20 slivers (from about 6 cloves) garlic cloves, peeled and cut into thin slivers (about 3 heads total — reserve remaining cloves for roasting alongside)
6 fillets anchovy fillets in oil, drained and cut in half lengthwise (optional but highly recommended — they dissolve completely and deepen the savory flavor without tasting 'fishy')
6 sprigs fresh rosemary sprigs
8 sprigs fresh thyme sprigs
3 tablespoons extra-virgin olive oil
2 tablespoons Dijon mustard
2 teaspoons kosher salt
1½ teaspoons freshly cracked black pepper
2 heads whole heads of garlic, tops cut off to expose cloves
½ cup dry white wine (such as Sauvignon Blanc or a dry Provençal white)
**Dry-brine the lamb (day before or morning of):** Pat the leg of lamb completely dry with paper towels. Using a small sharp knife or the tip of a paring knife, make approximately 20 deep slits (about 1 inch / 2.5 cm deep) all over the lamb — top, bottom, and sides. Into each slit, push one garlic sliver and, if using, a half-strip of anchovy fillet along with a few leaves of fresh thyme pulled from a sprig. Don't skip the anchovy — it disappears entirely into the meat and creates an incredible depth of umami flavor. Season the lamb all over with the kosher salt and black pepper, pressing it firmly into the surface. Place uncovered on a rack set over a rimmed baking sheet and refrigerate uncovered for at least 4 hours, ideally overnight. This dry-brine creates a phenomenal crust.
**Bring lamb to room temperature:** Remove the lamb from the refrigerator 1 full hour before roasting. This is non-negotiable for even cooking — a cold center means overcooked edges by the time the middle reaches temperature. While the lamb rests on the counter, preheat your oven to 450°F (230°C) with a rack positioned in the lower third.
**Prepare the potato frites (first fry — do this while lamb roasts):** Cut the peeled potatoes into uniform sticks, approximately ¼ inch (6 mm) wide and 3 inches (7.5 cm) long. Place the cut potatoes immediately into a large bowl of cold water and soak for at least 20 minutes (up to 2 hours) — this removes surface starch and is the key to a crispy exterior. After soaking, drain and spread onto clean kitchen towels or paper towels and dry them *thoroughly* — any residual moisture in hot oil causes dangerous splattering and steaming instead of frying.
**Sear and start roasting the lamb:** Brush the room-temperature lamb all over with the olive oil, then spread the Dijon mustard evenly over the entire surface with your hands or a pastry brush — this helps build the crust and adds a subtle tangy depth. Place the lamb fat-side up in a large heavy-bottomed roasting pan (not a rack — the drippings will flavor the pan sauce and, later, the frites). Nestle the two halved garlic heads cut-side up around the lamb along with the remaining rosemary and thyme sprigs. Roast at 450°F (230°C) for 20 minutes. You'll see the outside turn deep golden and caramelized — this is the sear.
**Reduce heat and finish roasting:** After the initial 20-minute high-heat blast, reduce the oven temperature to 325°F (165°C). Pour the white wine and ½ cup (120 ml) of the stock into the bottom of the roasting pan — be careful, it will steam vigorously. Continue roasting until an instant-read thermometer inserted into the thickest part of the meat (away from the bone) reads 130°F (54°C) for medium-rare — the ideal temperature for lamb. For a 5–6 lb leg, this typically takes an additional 50–65 minutes at 325°F. **Check the temperature starting at 45 minutes.** Medium (pink throughout) is 140°F (60°C); well-done is 160°F (71°C) — though the French would gently discourage you from going past medium.
**Rest the lamb — this step is critical:** Transfer the roasted lamb to a large cutting board and tent loosely with aluminum foil. Rest for a minimum of 20 minutes — 30 minutes is ideal for a roast this size. The internal temperature will rise another 5–8°F (3–4°C) during resting, and the juices will redistribute throughout the meat. Cutting too early means all those precious juices run out onto your cutting board instead of staying in the meat. Use this resting time to make the pan sauce and finish the frites.
**Make the pan sauce:** While the lamb rests, place the roasting pan directly on your stovetop over medium-high heat. Skim off most of the excess fat (leave about 1 tablespoon), reserving a few tablespoons of the drippings separately for the frites if desired. Add the remaining ½ cup (120 ml) of stock and bring to a vigorous simmer, scraping up all the caramelized bits from the bottom of the pan with a wooden spoon — this is called deglazing, and those stuck-on bits are pure flavor. Squeeze the roasted garlic cloves from their papery skins directly into the sauce and whisk them in (they'll dissolve and thicken the sauce naturally). Simmer 3–4 minutes until the sauce reduces slightly. Remove from heat, swirl in the cold butter cubes until just melted and glossy, then stir in the chopped parsley. Season with salt and pepper. Strain through a fine mesh sieve for a silky restaurant-style finish, or leave it rustic — both are correct.
**First fry the potatoes (blanching fry):** While the lamb is in its final 20 minutes of roasting, heat your frying oil in a large, heavy-bottomed Dutch oven or deep pot to exactly 300°F (150°C) — use a candy or deep-fry thermometer. Add the thoroughly-dried potato sticks in batches (do NOT crowd the pot — work in 3–4 batches). Fry each batch for 4–5 minutes until the potatoes are cooked through and just barely beginning to color — they should be pale golden and slightly soft. Remove with a spider or slotted spoon and drain on paper towels in a single layer. Let them cool completely (at least 10 minutes) before the second fry. This two-stage frying process is the true secret to pommes frites that are simultaneously fluffy inside and shatteringly crispy outside.
**Second fry (the crispy fry — do this while lamb rests):** Raise the oil temperature to 375°F (190°C). If you reserved any lamb drippings, add them to the oil now for extra savory depth. Working in batches, fry the blanched potatoes a second time for 2–3 minutes until they are deeply golden, crackly, and irresistible. This second fry happens fast — watch closely. Drain on fresh paper towels and immediately season with flaky sea salt and the chopped parsley while still hot (the salt adheres while the surface is still glistening). Serve immediately — pommes frites wait for no one.
**Carve and serve:** Carve the rested lamb against the grain in long, ¼-inch (6 mm) slices, working around the bone. Arrange the slices on a warm serving platter, spoon the pan sauce over the top, and garnish with a few fresh rosemary sprigs. Set the platter at the center of the table alongside a mountain of the crispy, herb-flecked pommes frites. Accept the applause graciously.
Tips
**The anchovy is your secret weapon.** If you're nervous about it, don't be — anchovy fillets dissolve completely during roasting and leave zero fishiness behind. What they leave instead is an incredible savory depth that makes people say 'what IS that flavor?' and keep reaching for more. This is one of the oldest French tricks for roast lamb and it's absolutely worth it.
**Buy a meat thermometer if you don't own one.** This is the single most important piece of equipment for this recipe — not because it's difficult, but because every leg of lamb is slightly different in size and bone placement, and guessing by time alone will get you in trouble. A good instant-read thermometer costs $12–20 and will save your lamb (and your Easter dinner) indefinitely.
**Dry your potatoes like you mean it.** Wet potatoes in hot oil are dangerous (spattering) and produce steamed-soft rather than crispy frites. After soaking and draining, spread them on a clean kitchen towel, roll it up around them, and give them a firm squeeze. Then spread them on paper towels for 5 more minutes. You want them bone dry.
**Don't skip the rest.** If the 20–30 minute rest feels like torture when hungry guests are circling, hand them the pommes frites and a glass of Burgundy. The rest is mandatory for juicy lamb — a rested roast will retain its juices when carved; an unrested roast will bleed out on the board and leave you with dry meat. The frites will occupy everyone admirably.
**Ask your butcher to score the fat cap.** If your lamb comes with a thick fat cap, ask the butcher to score it in a crosshatch pattern (or do it yourself with a sharp knife, cutting through fat but not into the meat). This helps the fat render properly during roasting rather than creating a chewy layer, and it allows the mustard and seasoning to penetrate.
Storage
Leftover roasted lamb keeps beautifully wrapped tightly in plastic wrap or in an airtight container in the refrigerator for up to 3 days. Reheat gently in a covered baking dish with a splash of stock at 300°F (150°C) for 15–20 minutes to avoid drying out — or enjoy cold, thinly sliced in a baguette with Dijon mustard and cornichons, which the French will tell you is the *actual* best way to eat leftover gigot. Pan sauce stores separately in an airtight jar for up to 3 days; reheat gently on the stovetop. Pommes frites do not keep well — they are best consumed immediately after frying. If you have leftovers, reheat in a 400°F (200°C) oven on a wire rack for 8–10 minutes.
Make Ahead
This recipe is beautifully set up for make-ahead success. **Day before:** Dry-brine the lamb (step 1) — this actually *improves* the final result. Cut and soak the potatoes, drain them, dry them thoroughly, and store in a single layer on parchment-lined baking sheets in the refrigerator uncovered (the dry fridge air further dehydrates the surface). **Morning of Easter:** Complete the first (blanching) fry of the potatoes, spread on paper towels, and leave at room temperature for up to 4 hours — they're ready for the quick second fry right before serving. The pan sauce can also be made up to the point of adding butter and parsley, then finished to order in under 2 minutes. This staged approach means the dramatic, crispy second fry and final carving happen within 30 minutes of sitting down to eat — and everything feels effortless to your guests.
Gigot d'agneau is the French term for roasted leg of lamb — 'gigot' means leg and 'agneau' means lamb. It is the classic French Easter main course, typically larded with garlic and sometimes anchovies, rubbed with mustard and herbs, and roasted to a juicy medium-rare. It has been served at French Easter Sunday tables since medieval times.
What temperature should leg of lamb be cooked to for Easter dinner?
For the best Easter leg of lamb, roast to an internal temperature of 130°F (54°C) for medium-rare — the ideal doneness preferred by most French cooks. The meat will continue rising to 135–138°F during a 20–30 minute rest. For medium (pink throughout), target 140°F (60°C). Use an instant-read thermometer; do not rely on time alone, as every leg of lamb varies in size and bone placement.
How long does it take to roast a leg of lamb?
A 5–6 lb (2.3–2.7 kg) bone-in leg of lamb takes approximately 70–85 minutes total in this French method: 20 minutes at 450°F (230°C) for a high-heat sear, then 50–65 minutes at 325°F (165°C) to finish to medium-rare. Always verify doneness with a meat thermometer inserted into the thickest part of the meat away from the bone — target 130°F (54°C) for medium-rare.
Should I use bone-in or boneless leg of lamb for Easter?
Bone-in leg of lamb is strongly preferred for Easter roasting and for gigot d'agneau specifically. The bone conducts heat from the inside out, promotes more even cooking, adds deep flavor to both the meat and the pan drippings used for the sauce and pommes frites, and makes for a dramatically more impressive presentation at the table. Boneless works but requires reduced cooking time and loses some of the flavor complexity.
Can you really taste the anchovies in leg of lamb?
No — and this is the most common surprise for first-timers. Anchovy fillets dissolve completely into the meat during roasting at high heat and leave absolutely no fishy taste or smell. What they leave behind is a deeply savory, umami-rich quality that makes people keep reaching for more without being able to identify what makes the lamb taste so exceptional. It is one of the oldest French tricks for roast lamb and is 100% worth using.
What wine should I serve with French Easter leg of lamb?
The classic pairing for gigot d'agneau is a red Burgundy (Pinot Noir) or a structured red Bordeaux (Cabernet Sauvignon-Merlot blend). For a more accessible option, a good Côtes du Rhône or a Napa Valley Cabernet Sauvignon works beautifully. The wine you cook with (dry white wine for the pan sauce) can be Sauvignon Blanc or a dry Provençal white such as Bandol or Cassis.
How do I make pommes frites crispy at home?
Truly crispy homemade pommes frites require two steps: First, soak cut potatoes in cold water for at least 20 minutes to remove surface starch, then dry them completely — wet potatoes steam instead of fry. Second, fry them twice: once at 300°F (150°C) to cook through, let them cool completely, then fry again at 375°F (190°C) for 2–3 minutes until deeply golden and shatteringly crispy. Season with flaky sea salt immediately after the second fry and serve at once.
Can I make Easter leg of lamb ahead of time?
Yes — this recipe is excellently suited to make-ahead preparation. The night before, dry-brine the lamb (this actually improves the crust). The morning of Easter, complete the first blanching fry of the potatoes and hold them at room temperature for up to 4 hours. Begin the final roast 2.5–3 hours before dinner. The quick second fry of the frites and the final carving can both happen within 30 minutes of sitting down to eat.
What sides go with French Easter leg of lamb besides pommes frites?
Classic French accompaniments to gigot d'agneau include flageolet beans (the most traditional French pairing), ratatouille, roasted asparagus (seasonal for Easter spring), a simple green salad with Dijon vinaigrette, or haricots verts with shallots and tarragon. For a full French Easter spread, start with a spring soup or a brioche-based brunch before the lamb dinner.
How much leg of lamb do I need per person for Easter dinner?
Plan on approximately ¾ to 1 pound (340–450 g) of bone-in leg of lamb per person. A 5–6 lb bone-in leg generously serves 6 adults. For 8 guests, use a 7–8 lb leg and add approximately 15–20 minutes to the lower-temperature roasting time. Always verify with a meat thermometer regardless of weight.
