Whether you’re observing Lent or just craving something different from your usual burger, these chain restaurant offerings prove that fish can be the star of the sandwich show.
1. Popeyes Classic Flounder Fish Sandwich
Popeyes shocked the sandwich world when they applied their chicken expertise to seafood. The result? Pure magic in a brioche bun. Their thick flounder fillet comes encased in that signature crackling crust that shatters with each bite, while Cajun seasonings provide a gentle heat that wakes up your taste buds.

Available primarily during Lent, this seasonal treat often sticks around longer due to overwhelming demand. Fish sandwich aficionados regularly rank this newcomer at the top of their lists—and for good reason.
2. Culver’s North Atlantic Cod Filet Sandwich
Wisconsin-based Culver’s may be famous for ButterBurgers, but their cod sandwich deserves its own spotlight. Unlike many chain offerings, Culver’s uses wild-caught North Atlantic cod that’s hand-battered to order, ensuring that perfect balance between crispy exterior and flaky interior that lesser fish sandwiches can only dream of achieving.
The hoagie roll provides a sturdy foundation without being tough or chewy. A generous layer of tartar sauce adds creaminess, while fresh lettuce contributes a satisfying crunch and freshness.

From a chain that proudly proclaims “We have the meats,” Arby’s fish sandwich emerges as a surprising standout. This seasonal sensation features Alaskan pollock coated in a crunchy breading that maintains its texture from first bite to last—a rare achievement in fast-food fish.
The sesame seed bun adds a subtle nuttiness while providing the perfect soft-to-crisp ratio against the fish. Shredded iceberg lettuce delivers freshness and crunch, while their tangy tartar sauce cuts through the richness with just the right amount of acidity.

The steamed bun creates a pillowy softness that contrasts beautifully with the crisp-fried pollock patty.
That half-slice of American cheese? Pure genius. It adds just enough creamy melt without overwhelming the delicate fish flavor. The tartar sauce brings tangy zip that cuts through the richness perfectly.
While newer competitors boast bigger fillets or fancier ingredients, the Filet-O-Fish maintains its iconic status through simplicity and consistency. There’s something deeply comforting about this sandwich that transcends nostalgia, making it a legitimate contender rather than just a sentimental favorite.
