Norway has a unique twist on the beloved McDonald's Filet-O-Fish sandwich that has fans of the fast food chain hooked. In the Scandinavian country, the sandwich is often upgraded with a few simple yet game-changing modifications. Instead of the usual tartar sauce, Norwegians prefer to top their Filet-O-Fish with a generous dollop of mayonnaise, which adds a rich and creamy texture to the dish. But that's not all - they also often swap out the lettuce for pickled red onion, giving the sandwich a tangy and slightly sweet flavor. With these tweaks, the humble Filet-O-Fish is transformed into a satisfying and savory meal that's sure to delight even the most discerning palates.


McDonald's Filet-O-Fish is a fan favorite worldwide, but if you want to upgrade your fish sandwich, consider ordering it the way those in Norway do.
