The Filet-O-Fish sandwich at McDonald's is made from a breaded pollock fish patty, tartar sauce, and a soft bun. The fish patty contains a specific blend of ingredients to create its signature texture and flavor.
The fish patty is formed from minced pollock mixed with fillers like wheat starch, sugar, and sodium phosphate. These additives help bind the fish together and improve its texture when fried. The patty is then breaded and deep-fried to achieve its crispy exterior.
| Ingredient | Purpose |
|---|---|
| Pollock fish | Main protein source |
| Wheat starch | Binder and thickener |
| Sugar | Enhances flavor and browning |
| Sodium phosphate | Retains moisture and improves texture |
| Tartar sauce | Adds tangy flavor |
| Soft bun | Provides structure |
Many people assume the Filet-O-Fish is made with cod, but McDonald's switched to pollock in 2016 due to sustainability concerns. Pollock is a more abundant and responsibly sourced fish.
According to McDonald's, pollock offers a consistent texture and mild flavor that works well in their sandwich. The company sources its pollock from certified sustainable fisheries to meet environmental standards.
I once ordered a Filet-O-Fish expecting cod and was surprised by the lighter taste of pollock. The switch makes sense for both quality and environmental reasons.
The Filet-O-Fish was introduced in 1962 as a Lenten option for customers who abstained from meat. It remains popular as a vegetarian-friendly choice, though it contains fish. The sandwich is available year-round at most McDonald's locations.
