🇦🇷 Argentina · Family: Lomito · Heat: Grilled · Bread: pan-frances · Proteins: beef, ham, egg
The Lomito Completo is the Argentine tenderloin sandwich taken to its maximal form, grilled lomo loaded with lettuce, tomato, ham, cheese, a fried egg, and mayonnaise into a single massive, indulgent build. The angle is abundance held together: the completo adds every standard topping at once, so it hinges on whether the bread and the assembly can carry that load without the tenderloin getting lost or the whole thing sliding apart. Get it right and each element registers, the lean seared meat still leading despite the company. Get it wrong and it is a wet, overstuffed brick where the steak is buried under egg and mayonnaise and the bread has given out underneath.
The build starts from the standard lomito and stacks everything onto it. The bread is a substantial roll, pan francés or a wider sandwich loaf, split and toasted so it has a fighting chance against the moisture coming. The lomo is sliced thin and grilled fast or seared on a plancha, kept pink inside because the lean cut goes dry if pushed. Onto the hot meat goes melted cheese, then ham, then a fried egg with the yolk usually left runny, then lettuce and tomato for whatever freshness can survive the pile, and a slick of mayonnaise binding it. The order matters: cheese on the hot meat so it melts, egg high so the yolk runs down through the stack, salad near the top so it stays distinct. Good execution keeps the tenderloin seared and juicy under all of it, the egg cooked so the yolk is liquid but not raw, the bread toasted firmly enough to hold the weight, every layer still identifiable in the bite. Sloppy execution overcooks the lean meat, hard-fries the egg into rubber, drowns it in mayonnaise, and lets the roll collapse into a sodden mass.
It varies mostly by how strictly the full set is applied and by region. Some kitchens add bacon or sautéed onions to push it further; others hold to the canonical six toppings and trust the combination. Pull elements off and it slides back toward simpler builds: drop everything but the egg and it becomes the con huevo; strip to meat, lettuce, and tomato and it is the común. The completo is the upper bound of the lomito family, the loaded extreme the bare versions are defined against, and those simpler builds, the común, the con huevo, the umbrella al pan, each deserve their own treatment as deliberate steps down from this one.
