Chicken Bacon Onion con Pollo del McChicken

Chicken Bacon Onion con Pollo del McChicken is a limited-edition sandwich that appeared at McDonald's Porto Imperial in Porto, Portugal, as documented by creator Giovanni Fois. The dish reimagines the classic McChicken by adding crispy bacon and grilled onions, creating a savory, smoky variation on the standard fast-food chicken sandwich.

The sandwich starts with the familiar McChicken patty—a breaded and fried chicken cutlet—then layers it with strips of bacon and a generous portion of sautéed or grilled onions. What distinguishes a great version of this sandwich is the balance of textures: the crunch of the bacon and the tender chicken should contrast with the soft, caramelized sweetness of the onions. The onions must be cooked until they are deeply browned and almost jammy, avoiding any raw bite that would disrupt the harmony of flavors. A well-made Chicken Bacon Onion con Pollo del McChicken also ensures the bun is lightly toasted to hold up against the moisture of the onions and the richness of the bacon.

Regional variations of this concept are common in fast-food markets worldwide. In the United States, similar offerings have appeared as the "McChicken with Bacon" or "Southern Style Chicken Sandwich with Bacon," often featuring mayonnaise or a creamy sauce. In parts of Asia, teriyaki-glazed onions might replace the grilled version, adding a sweet-savory umami note. The Porto iteration, however, stands out for its simplicity and directness, letting the core ingredients—chicken, bacon, onion—speak for themselves without additional sauces or condiments.
