The McDonald’s Filet-O-Fish sandwich is a beloved staple on the fast-food chain’s menu, introduced in 1962 to cater to Roman Catholic customers abstaining from meat on Fridays during Lent.
Over the decades, the sandwich has become an iconic offering, favored for its mild taste and lighter alternative to beef-based options. But have you ever wondered exactly what type of fish is used in your Filet-O-Fish sandwich?
Type of Fish
Identification of the Fish Used
McDonald’s primarily uses wild-caught Alaska Pollock for its Filet-O-Fish sandwiches. This species is chosen for its mild flavor, flaky texture, and sustainable abundance in northern waters. Occasionally, other whitefish species may be used depending on regional availability, but Alaska Pollock is the standard fish globally.
Common Species and Scientific Name
The fish in the Filet-O-Fish is most commonly sourced from the Alaska Pollock (scientific name: Gadus chalcogrammus), a species closely related to cod and haddock. This type of fish is known for its delicate, flaky texture and neutral flavor, making it an ideal candidate for a mass-market sandwich.
Sourcing
Where McDonald’s Sources Its Fish
McDonald’s prides itself on sourcing fish from sustainable fisheries. The majority of the fish used in the Filet-O-Fish comes from the Bering Sea and Gulf of Alaska, known for their robust fish populations and well-managed fisheries.
Sustainability Practices Involved
McDonald’s is committed to sourcing fish responsibly, ensuring that the Filet-O-Fish meets high sustainability standards. Most of the fish is certified by the Marine Stewardship Council (MSC), an independent non-profit organization that sets standards for sustainable fishing.
The MSC certification guarantees that the fish is wild-caught and that the fisheries follow practices to prevent overfishing and reduce environmental impact.

Preparation Process
Overview of How the Fish Is Prepared
McDonald’s prepares its Filet-O-Fish sandwiches in a consistent and standardized manner across all of its locations. The fish fillet is coated in a light, crispy breading rather than a heavier batter. After being coated, the fillets are deep-fried until golden, giving them a crunchy texture that complements the soft bun and creamy tartar sauce.
Breaded vs. Battered
Unlike many fast-food competitors who use heavier batter, McDonald’s opts for a breaded fish fillet. The lighter breading allows the natural flavor of the Alaska Pollock to shine through, rather than being masked by excess oil or thick coating.
Cooking Methods
The fish fillet in the Filet-O-Fish is deep-fried, ensuring that it is hot, crispy, and flavorful. The quick frying process helps seal in moisture while creating a crunchy exterior.
Flavor Profile
Description of Taste and Texture
The Alaska Pollock used in the Filet-O-Fish has a mild, slightly sweet flavor with a flaky, tender texture. Its subtle taste allows the other elements of the sandwich—such as the creamy tartar sauce, processed American cheese, and soft steamed bun—to stand out without overpowering the dish. The light breading adds a satisfying crunch, complementing the sandwich’s soft and creamy textures.
How the Fish Complements Other Sandwich Ingredients
The mild flavor of the Alaska Pollock pairs well with McDonald’s tartar sauce, which is rich and slightly tangy. The slice of processed American cheese adds creaminess, while the soft steamed bun provides a neutral base that doesn’t compete with the fish.
Overall, the ingredients come together to create a balanced, satisfying sandwich that appeals to a wide range of tastes.
Comparisons
Comparison to Other Fast-Food Fish Sandwiches
When compared to other fast-food fish sandwiches, the Filet-O-Fish is often seen as one of the more consistent and reliable options. Some competitors use heavier battered fish, which can be more filling but also oilier.
Others might opt for different species of fish, such as cod or haddock, which can have a stronger flavor. McDonald’s Alaska Pollock, with its mild taste and light breading, tends to have a broader appeal, particularly for customers looking for a simple, no-frills fish sandwich.
Consumer Preferences and Trends
The Filet-O-Fish remains a popular choice for those seeking a pescatarian-friendly option or simply a lighter alternative to beef or chicken sandwiches. It continues to be a go-to meal during Lent, but its appeal extends far beyond religious observance, thanks to its nostalgic value and consistent quality.
