Italian Basilicata Lamb Stew | Cutturiddi di Agnello
Cutturiddi is what a shepherd cooks when the only equipment is a fire, one earthenware pot and whatever the flock and the hillside gave up that morning. Pieces of lamb on the bone go into cold water, and over the next two hours onion, tomato, bitter field greens and potatoes are added in sequence until the water has turned into something halfway between a broth and a sauce. Nothing is browned. Nothing is thickened.
The dish belongs to the inland Basilicata of the Lucanian Apennines, where sheep farming shaped the cooking far more than the sea ever did. Its name comes from the cutturo, the copper cauldron that hung over the hearth, and the method follows from the vessel: one pot, one fire, everything cooked in the same liquid from first minute to last.
This is not the same dish as cutturiddu lucano made with mutton, and it is not pignata di pecora alla lucana either. Those use older sheep and a longer harder cooking. Cutturiddi di agnello is the young lamb version: milder, faster, greener, built around spring greens and new potatoes rather than the deep gaminess of an old animal.
Yield: 5 servings. Prep: 30 minutes. Cook: 2 hours 15 minutes. Rest: 15 minutes. Total: about 3 hours. Difficulty: intermediate. Course: secondo piatto. Region: Basilicata, inland Potenza and Matera.
The Story
Basilicata is the most mountainous region of southern Italy and for centuries it was the poorest. Its cooking was shaped by transhumance, the seasonal movement of flocks between the summer pastures of the Apennines and the winter grazing of the Metaponto plain, and by the tratturi, the wide drovers roads that carried them. A shepherd on the move had salt, a knife and a pot, and everything else came from the animal and the ground he was walking over.
The lamb was almost never a prime cut. Shoulder, neck, breast and shank, the parts full of connective tissue and bone, are what a shepherd would sacrifice and what the market would not take, and they are exactly the parts that reward long wet cooking. The bones are what give the finished liquid its body. The local agnello lucano, raised on wild upland pasture, has pale firm flesh and a clean flavour that carries herbs instead of fighting them.
The greens are the other half of the story. Wild chicory, borage and wild fennel were gathered along the way, free and bitter, and they are not a garnish here but a structural ingredient. Bitterness is the counterweight to lamb fat, and a cutturiddi without it tastes heavy and flat. Add the peperone crusco of Senise crumbled over the top and a grating of Pecorino di Filiano, and the region is on the plate.

Preparation
Starting the lamb in cold water
Rinse the lamb pieces and put them into a large earthenware pot or a heavy casserole. Cover them with the 6 cups (1.4 L) of cold water, so the liquid sits about one inch above the meat. Add 1 teaspoon of the salt and bring the pot very slowly to a bare simmer over low heat, which should take a good 25 minutes.
Skimming the pot
As the water approaches a simmer a grey foam will rise. Skim it off with a ladle until nothing more comes up and the liquid runs clear. What you are removing is coagulated blood protein, not fat, and leaving it in gives a muddy taste and a cloudy broth. The fat that rises afterwards stays: it is what will emulsify later.
Adding the aromatics
Once the pot is clear, add the sliced onions, the tomatoes, the celery stalk, the crushed garlic, the bay leaves, the chilli and the olive oil. Put the lid on slightly ajar and hold the pot at the gentlest possible simmer, with only occasional bubbles breaking the surface. Cook for 1 hour 15 minutes without stirring. If the liquid drops below the meat, top it up with hot water, never cold.
Preparing the field greens
While the lamb cooks, wash the chicory in several changes of water, since wild greens hold grit at the base of the stems, and trim the tough root ends. Blanch the chicory in salted boiling water for 4 minutes, then the borage for 1 minute, and drain both well. This removes the harsh edge of the bitterness while keeping the useful part of it.
Adding the potatoes
At the 1 hour 15 minute mark the lamb should be tender but not yet falling from the bone. Add the potato chunks and the remaining salt, pushing them down so they are covered, and cook uncovered for 30 minutes. This is where the dish thickens: the potato starch leaches into the broth and gives the liquid a soft body no flour could imitate.
Adding the greens and finishing
Add the blanched chicory and borage and the wild fennel, tucking them between the pieces of meat rather than piling them on top. Simmer for a final 15 to 20 minutes, until the lamb pulls away from the bone at the touch of a spoon and the liquid coats the potatoes. Taste now and only now, because the reduction has been concentrating the salt for two hours. Add the parsley and a grind of black pepper.
Resting the pot
Take the pot off the heat, put the lid on and let it stand for 15 minutes. The lamb reabsorbs liquid as it cools slightly, the fat and the broth settle into an emulsion instead of separating, and the potatoes stop being fragile enough to break when you lift them. While it rests, toast the peperone crusco: 10 seconds a side in a dry hot pan, and it burns in fifteen.
Plating
This is served in bowls, not flat plates, because a third of the pleasure is the liquid. Warm the bowls properly: a cold bowl chills lamb fat within seconds and turns a glossy sauce waxy. Lift the meat out with a slotted spoon so the pieces stay intact, two or three to a bowl, then add the potatoes and a tangle of greens beside the meat rather than under it.
Ladle the broth over until it comes halfway up the meat. Grate the pecorino over each bowl while it is hot enough to soften the cheese, crumble the toasted peperone crusco over that, and finish with a thread of raw olive oil. Put the bread on the table and nothing else: a salad of raw bitter leaves is the only accompaniment this dish has ever needed.
Professional Technique
Every professional instinct says to brown the lamb first, and here that instinct is wrong. Searing builds flavour in the crust and in the fond, and both are then dissolved into the braising liquid, which is why a browned braise tastes roasted and dark. Cutturiddi is not trying to taste roasted. Its target flavour is clean lamb, sweet onion, bitter green and mineral broth, all legible separately, and a Maillard crust would cover that with one layer of caramelized savour under which the greens vanish.
The cold water start is the mechanism that makes it work. When meat goes into cold water and heats slowly, the soluble proteins and the collagen dissolve gradually into the liquid over a long window instead of being locked behind a seared surface. That is what builds a broth with body out of what is technically just water and lamb. Put the same meat into boiling water and the outer proteins contract instantly, far less collagen migrates out, and you finish with tender meat sitting in thin liquid.
What binds the finished sauce is a genuine emulsion from two sources. Lamb fat, rendered slowly and never boiled hard, disperses as small droplets held there by the gelatin the bones and connective tissue released, and that gelatin is the emulsifier. Then the potato starch gelatinizes into the same liquid, raising its viscosity and stabilizing those droplets so they cannot coalesce and float. The bitter greens are the last piece: their bitterness cuts straight through the coating lamb fat leaves on the palate and resets the taste between mouthfuls, which is why blanching them past the four minute mark throws away the reason they are in the pot.
Texture and Moisture Control
Three things have to be right at the same moment: the lamb tender to the bone but still in recognisable pieces, the potatoes soft and holding their shape, the liquid thickened but not sticky. Lamb held at a real boil turns stringy, because the muscle fibres contract and squeeze out moisture faster than collagen converts to gelatin. Kept just below a simmer, at around 185°F (85°C), that conversion wins and the meat ends up moist.
Potatoes are the fragile element. Use a waxy variety, cut no smaller than 1 1/2 inches (4 cm), added exactly 45 minutes before the end. A floury potato put in early disintegrates and turns the broth into a grey purée, which is the commonest way this dish is ruined, and small pieces do the same. If the liquid is still thin at the end, lift the meat out and reduce the broth alone rather than boiling everything.
Professional Mise en Place
This is a long cook with a short attention span: two hours of near passive simmering with three timed interventions. Nearly everything can be prepared while the pot is on the fire.

Prepared ahead
Lamb cut into pieces by the butcher, bones kept, refrigerated until it goes in
Greens washed, trimmed, blanched and pressed, up to 1 day ahead
Onions sliced, tomatoes peeled and chopped, aromatics tied together
The whole stew cooked 1 day ahead, stopping before the greens go in
Service setup
Bowls warm, never cold, and bread on the table before the pot leaves the stove

Pecorino grated to order, peperone crusco toasted at the last moment
Finishing olive oil beside the stove, not in the pot
Chef Tips
Ask the butcher for shoulder and neck together, bones included, and refuse boneless leg however good it looks. The bones and the connective tissue are where the body of this broth comes from, and lean boneless lamb gives you dry meat in watery liquid.
Make it the day before. It is measurably better after a night in the refrigerator, because the gelatin sets and the flavours settle into each other. Hold the greens back and add them on the day you serve it, so their bitterness and colour are fresh.
If wild chicory is not available, catalogna from the market is the closest cultivated relative and behaves the same way, and dandelion greens, escarole and the outer leaves of radicchio all work. What does not work is spinach, which collapses and brings no bitterness, or kale, which stays tough.
Treat the peperone crusco with respect, because it is the one ingredient here that is genuinely easy to destroy. It goes into a dry pan with no oil, about 10 seconds a side, only to make it brittle and aromatic. A second too long and it turns acrid.
Common Mistakes
Browning the lamb first. It turns cutturiddi into an ordinary braise. The roasted flavour of a seared crust dominates the clean lamb and bitter green profile, and it seals the surface so far less collagen dissolves into the broth.
Letting the pot boil. A rolling boil contracts the muscle fibres and drives moisture out faster than collagen can turn to gelatin, so the meat finishes stringy, and it breaks the fat and broth emulsion so the surface goes oily. Keep it barely trembling.
Using floury potatoes or cutting them small. They disintegrate into the liquid and turn the stew into a grey mash. Use a waxy variety, cut no smaller than 1 1/2 inches (4 cm), added only 45 minutes before the end.
Skipping the skimming. The grey foam that rises in the first minutes is coagulated blood protein and it tastes muddy. Take it off until the liquid runs clear, but leave the fat that rises afterwards, since the sauce needs it.
Adding the greens too early. Bitter greens simmered for an hour lose their bitterness and their colour with it, and the dish then has nothing to cut the lamb fat. Give them 15 to 20 minutes in the pot, no more.
Topping up with cold water. It drops the pot temperature sharply and interrupts the slow collagen conversion the method depends on. Keep a kettle beside the stove.
Wine Pairing
Aglianico del Vulture Superiore DOCG: The local answer and by a wide margin the best one, grown on volcanic soil on the slopes of Monte Vulture. Its tannin is firm and fine grained rather than coarse, and it binds the lamb fat directly, clearing the palate without stripping the meat of flavour. Underneath, sour cherry acidity and a smoky mineral edge run alongside the bitter greens instead of arguing with them.
Aglianico del Taburno DOCG: The same grape in a gentler accent, from the limestone hills of the Taburno. It carries less tannic weight and more red fruit than the Vulture bottlings, which suits young lamb. The acidity lifts a broth enriched with gelatin and potato starch, and the faint bitter almond note on its finish sits comfortably beside chicory.
Cesanese del Piglio DOCG: A medium bodied red from inland Lazio with soft dusty tannins, dark cherry fruit and a note of dried herbs and black pepper. That herbal register is why it belongs here: it echoes the wild fennel and bay in the pot. Served at around 61°F (16°C) it handles the fat without dominating the greens.
Primitivo di Manduria DOC: The choice when the lamb is generously fatty and the pot has reduced hard, since its ripe plum fruit and warm alcohol give a broad soft cushion against richness rather than a tannic scrape. Pick a dry unoaked version and avoid the sweeter modern bottlings, because residual sugar fights the bitter greens badly. Its gentle tannin suits meat that has fallen from the bone.
Montepulciano d'Abruzzo DOC: The reliable everyday bottle for this pot and the one with the widest margin for error. Deep coloured, moderately tannic, with brambly dark fruit and a savoury slightly bitter finish, it has enough grip to meet lamb fat and enough acidity to keep a starch thickened broth from tasting heavy.
Storage & Reheating
This is a dish that genuinely improves overnight, so cook it a day ahead when you can. Cool it uncovered for no more than an hour, then refrigerate it in the pot or a sealed container for up to 3 days. The surface sets with a firm fat cap and the broth underneath goes almost solid with gelatin, which is the sign the cooking temperature was right. Lift the cap off for a lighter dish or stir it back in for the traditional one.
Reheat on the stove over low heat, covered, never in a microwave and never at a boil, since boiling reheated lamb dries it out and splits the emulsion. Give it 20 minutes and add a little hot water if the liquid has tightened. It freezes for up to 2 months, but without the potatoes, which go grainy: add freshly cooked ones when you reheat it.
