What is a Tostado in Argentine Cuisine?

  • A tostado is a toasted bread slice, usually served warm and butter‑ed, that forms the base for many popular Argentine snacks.
  • Common toppings include ham, cheese, tomato, lettuce, and a signature “carlito” spread-a blend of mayonnaise, ketchup, and a dash of Worcestershire sauce.
  • The simplicity of the tostado makes it a staple at cafés, bodegones, and street‑food stalls across Buenos Aires, Córdoba, and Rosario.

Top Spots to Experience an Authentic Carlito in Argentina

Practical Tips for the Perfect Tostado Experience

  • Bread Selection – Opt for a slightly dense loaf; it holds toppings without becoming soggy.
  • Temperature Control – Toast just enough to crisp the crust while keeping the interior soft; over‑toasting can dry the bread.
  • Sauce Ratio – Balance the carlito sauce; too much overwhelms the ham, too little leaves the sandwich dry.
  • Accompaniments – Pair with a traditional mate infusion or a cold cerveza (lager) for a full Argentine snack session.
