Gigot à la boulangère ('baker's wife style') is one of the great French country roasts — a whole leg of lamb placed on a bed of thinly sliced potatoes and onions moistened with stock, the entire assembly roasted together so the potatoes absorb the lamb drippings and become rich, golden, and saturated with meat flavour. The name derives from the tradition of bringing the prepared dish to the village baker's oven (boulangerie) after the bread was done, using the residual falling heat of the wood-fired oven. The preparation: take a 2-2.5kg bone-in leg of lamb, stud with 12-15 slivers of garlic (insert into small incisions made with a paring knife, pushing the garlic 2cm deep into the flesh), and season aggressively with salt, pepper, and herbes de Provence. Thinly slice 1.5kg waxy potatoes (3mm, using a mandoline) and 3 large onions. Layer the potatoes and onions in a large roasting dish with thyme, bay, salt, and pepper, then pour over 400ml hot lamb or chicken stock — the liquid should reach just below the top layer of potatoes. Place the lamb directly on the potato bed. Roast at 220°C for 20 minutes, then reduce to 180°C for a further 60-70 minutes (25 minutes per 500g for rosé, 55-58°C at the thickest part of the leg). The lamb juices drip continuously into the potatoes below. Rest the lamb on a board for 20 minutes. Return the potato dish to the oven for 10 minutes at 220°C to crisp the top. The potatoes should be golden on top, creamy and lamb-flavoured beneath. Carve the leg at the table, serving thick slices with generous spoonfuls of boulangère potatoes.
Stud with garlic deep into the flesh — surface garlic burns; embedded garlic perfumes from within Slice potatoes 3mm thin — too thick and they remain raw; too thin and they dissolve Stock to just below the top layer — fully submerged potatoes steam; exposed tops crisp Lamb directly on the potatoes — the drippings must fall into them Crisp the potato top after resting the lamb — the final blast produces the golden gratin surface
Add a few anchovies dissolved into the stock before pouring over the potatoes — this Provençal trick adds umami depth without any identifiable fish flavour Scatter a handful of fresh thyme leaves over the potatoes 5 minutes before the final crisping — they toast and become intensely fragrant A gigot boulangère made with lamb shoulder instead of leg (longer cooking at 160°C for 3-4 hours) produces falling-apart meat and richer potatoes — a magnificent Sunday lunch variation
Using floury potatoes that disintegrate into mush — waxy varieties (Charlotte, Ratte, Kipfler) hold their shape Not enough stock — the potatoes dry out and burn on the bottom before they cook through Removing the lamb and potatoes together — the potatoes need a final crisping blast that would overcook the resting lamb Forgetting to stud with garlic — the garlic-lamb symbiosis is the soul of this dish Overcooking the lamb past medium — a boulangère gigot should be carved rosé; the potatoes provide the comfort
