Morcilla Argentina
Morcilla criolla
Buenos Aires & the Pampas
Morcilla is the opening act of every Argentine asado. The asador places these blood sausages on the grill first because they cook the fastest, buying time while beef ribs and flanks take their slow turn over the coals. The criolla version, dominant in Buenos Aires and the Pampas, packs pig's blood with chopped onion, cumin, and oregano inside a natural casing. Grilled until the skin blisters and cracks, each bite gives way to a soft, iron-rich interior. Argentines eat morcilla hot, often tucked into bread as a morcipan, while standing around the parrilla with a glass of Malbec.
History
Blood sausage came to Argentina with Spanish and Italian immigrants in the 19th century. The gauchos of the Pampas adopted it fast. Cattle were king, but nothing went to waste after a slaughter: blood, offal, intestines all had a purpose. Morcilla found its place as the first course of the asado, a tradition codified over generations. Two camps formed. The morcilla criolla, loaded with onion and local spices, became the Buenos Aires standard. The morcilla vasca, a Basque-influenced version with rice or breadcrumbs, held ground in Patagonia and parts of the interior. Today every carniceria in Argentina stocks morcilla, and no asado is complete without it.
Ingredients
Preparation
The butcher cooks diced onions until soft and mixes them into fresh pig's blood along with cumin, oregano, garlic, salt, pepper, and cubed pork fat. This mixture goes into natural casings, tied into links of about 15 centimeters. The morcilla is then poached in water just below boiling to set the blood. At the asado, the links go on the grill over moderate coals. The asador turns them with care: too much heat bursts the casing, too little leaves the skin flabby. Done right, the skin turns crisp and dark while the filling stays creamy.
Taste
Iron and onion up front. The cumin adds warmth without heat. Oregano lingers. The pork fat gives richness, and the grilled casing brings a smoky, charred note that balances the mineral tang of the blood.
Texture
Crisp skin that snaps under your teeth, giving way to a soft, almost paste-like interior. The chopped onion pieces add small pockets of texture inside the smooth blood filling. When grilled right, the contrast between crunchy outside and creamy inside is what makes morcilla work.
Rituals & Traditions
Morcilla opens the asado
The asador grills morcilla first. It cooks in minutes while the beef needs hours. Guests eat the achuras (offal course: morcilla, chinchulines, riñones) standing around the grill, drinking wine. The main cuts come later. Skipping the morcilla is like skipping the overture.
Eat it hot, eat it now
Morcilla waits for nobody. The moment the asador pulls it from the grill, you cut it open and eat. Cold morcilla loses its crispy skin and the filling turns grainy. Two minutes is the window.
Never microwave morcilla
Reheating morcilla in a microwave turns the casing rubbery and the filling into a grainy mess. If you have leftover morcilla, crumble the filling into a hot pan and use it in empanadas or over pizza. The casing goes in the trash.
The morcipán
Like the choripán (chorizo in bread), the morcipán puts grilled morcilla inside a crusty roll with chimichurri. Street vendors sell them outside football stadiums across Buenos Aires. It is fast food with a long pedigree.
Recipes
Morcilla al Asador
Morcilla Argentina
The traditional way to grill morcilla at an Argentine asado. No tricks, no sauce, no garnish. Just morcilla, fire, and timing. The asador places the links on the cooler edge of the grill and lets them heat through before moving them over direct coals to crisp the skin. Served on a wooden board with a knife and nothing else.
Pizza con Morcilla y Morrones
Morcilla Argentina
Argentine pizza has thick dough, heavy cheese, and toppings that would make a Neapolitan weep. This version scatters crumbled morcilla and strips of roasted red pepper (morrones) over a bed of mozzarella. The morcilla fat renders into the cheese during baking, and the peppers add a sweet char. Sold by the slice at pizzerias along Avenida Corrientes in Buenos Aires, usually at 2am after a night out.
Empanadas de Morcilla
Morcilla Argentina
Empanadas filled with crumbled morcilla and caramelized onion. A use for leftover morcilla that upgrades the filling far beyond the standard beef picadillo. The onion brings sweetness, the morcilla brings iron and depth. Bake them until the dough turns golden and flaky. Common at weekend asados when someone brings too much morcilla (a problem that solves itself).
Morcilla con Humita
Morcilla Argentina
Humita is Argentina's creamed corn, cooked slow with onion, butter, and a pinch of paprika. Spooned into a bowl and topped with crumbled grilled morcilla, it becomes a hearty one-dish meal. The sweet corn and the mineral blood sausage pull in opposite directions, and that tension makes the dish work. Popular in the northwestern provinces and at home kitchens during corn season (January through March).
Morcilla con Provoleta
Morcilla Argentina
Two asado staples combined into one dish. Provoleta (thick-sliced provolone grilled until bubbly and golden) gets topped with crumbled morcilla and a drizzle of chimichurri. The melted cheese catches the crumbled filling and holds it together. You scoop it up with bread. A fixture of the achuras course at parrillas across Buenos Aires.
Morcipán
Morcilla Argentina
The blood sausage sandwich of Buenos Aires. A grilled morcilla split open and stuffed into a crusty bread roll with chimichurri. Street vendors sell them outside football stadiums and at weekend ferias. The bread soaks up the fat and juices. You eat it standing, with napkins, fast.

Where to Eat
Don Julio
Buenos Aires, Argentina
A Palermo parrilla that ranks among the world's best restaurants. The wine wall holds over 14,000 bottles, and the beef comes from their own cattle in the Pampas. But before any steak arrives, the achuras course sets the tone: morcilla, chinchulines, and sweetbreads grilled over hardwood charcoal. The morcilla at Don Julio has a crisp, almost shattered skin and a filling so creamy it pools on the plate when you cut it open. Reservations fill weeks ahead. The corner building on Guatemala street has no sign, just a line.
El Desnivel
Buenos Aires, Argentina
A no-frills San Telmo parrilla that has fed the neighborhood since the 1970s. Plastic tablecloths, house wine in a jug, and a grill visible from every table. The achuras here are the real draw: morcilla, chinchulines, and mollejas come out fast and hot. The morcilla is grilled hard, almost blackened, with a filling packed with onion. Locals and tourists crowd the narrow room. Nobody comes here for decor. They come because the meat is honest, the portions are large, and the price is right.
La Brigada
Buenos Aires, Argentina
A San Telmo institution wrapped in football memorabilia (Maradona's jersey hangs on the wall). La Brigada is famous for one rule: no steak knives. The waiter cuts your bife de chorizo with the edge of a plate to prove how tender the meat is. The achuras course here is serious. The morcilla is thick, short-linked, and grilled over quebracho charcoal. The filling has a pronounced cumin note. Waiters in white jackets move through a dining room packed with framed photos of old Buenos Aires. Book ahead or prepare to wait on the sidewalk.
La Cabrera
Buenos Aires, Argentina
An upscale Palermo Soho parrilla known for its over-the-top presentation. Each main course arrives with a wooden board of small side dishes: roasted garlic, caramelized onions, peppers, and more. But the achuras course at the start is what sets the meal up. Their morcilla comes split and grilled face-down on the plancha, giving extra char to the filling itself. It arrives on a cast-iron plate still sizzling. The restaurant spills across two buildings on Thames street and runs late into the night.
