President Donald Trump has recently shone the spotlight on one of McDonald’s most beloved sandwiches. His remarks during the company’s 2025 Impact Summit in Washington, D.C., have sparked renewed conversation about the timeless Filet-O-Fish. This sandwich, originally introduced as a response to the dietary restrictions of Lent in the 1960s, remains a staple on the fast-food chain’s menu.
During his speech earlier this week, Trump expressed his admiration for the fish sandwich while also suggesting minor improvements, a reflection of his longstanding fondness for McDonald’s that dates back to his 2016 campaign. Fans of the fast-food giant know that he often includes the Filet-O-Fish in his orders.
The Filet-O-Fish’s origins trace back to 1962 when Lou Groen, a franchisee in Cincinnati, noticed that Friday sales were sluggish in his mostly Catholic neighborhood. Observing that many customers abstained from eating meat during Lent, Groen set forth the idea of introducing a breaded fish sandwich.
Initially, McDonald’s founder Ray Kroc was skeptical of Groen’s proposal. He pushed an alternative called the Hula Burger, which was simply a slice of grilled pineapple and cheese on a bun. To settle the matter, Kroc and Groen decided to test both sandwiches on a single Friday. The results shocked Kroc; the Filet-O-Fish sold an astounding 350 units, in stark contrast to the Hula Burger’s mere 6 pieces.
As Mike Bullington, McDonald’s corporate historian, remarked, “Fred got a new suit and McDonald’s got the Filet-O-Fish.” This variation not only became a permanent menu item in 1965 but also marked the first non-hamburger offering, priced initially at just 29 cents.
The success of the Filet-O-Fish transformed McDonald’s into a significant buyer of whitefish in the United States. The sandwich has played a vital role in creating sustainable demand for pollock, a fish commonly used in many fast-food offerings nationwide.
According to McDonald’s, the Filet-O-Fish enjoys global popularity, particularly in markets such as Russia, Japan, and India. Its international versions often come with unique ingredients, like wasabi sauce in some Asian markets or Old Bay tartar sauce in select U.S. restaurants.
Despite its decades-long success, Trump and other fans have voiced their opinions on how the Filet-O-Fish could be enhanced. Trump humorously noted the need for more tartar sauce, stating, “You could do a little bit more tartar sauce, though, please. I hate having to ask for more sauce. Seriously.” His comments resonated with many fans who echoed similar sentiments on social media.
In response to a Facebook post about Trump’s remarks, users expressed agreement, saying they often have to request extra tartar sauce to achieve the ideal flavor profile.
One comment captured the essence of the conversation: “Agree! I have to ask for extra tartar sauce,” a sentiment that many others shared. Another user chimed in, stating, “PREACH; the F-O-F is magnificent, but it can be a bit dry without the full squeeze of tartar sauce. I always ask for extra.” Such dialogue highlights the nostalgic attachment fans have for the Filet-O-Fish, even as they seek to enhance its taste.
Another topic of discussion among fans revolves around the sandwich’s cheese component. Typically, the Filet-O-Fish features only half a slice of American cheese, a decision some believe is primarily a cost-saving measure. However, McDonald’s has clarified that this half slice is a nod to Groen’s original recipe from 1962.
As the company noted, “The Filet-O-Fish has always come with a half slice of cheese. This is to save on the flavor of the sandwich.” Customers can request a full slice of cheese, but many still question the reasoning behind the half slice.
Over the years, fans have shared their creative ways to modify the Filet-O-Fish, enhancing their experience even further. In a Reddit thread, users suggested ordering additional fish patties, transforming the classic sandwich into a double or triple. This adaptation aims to achieve a better ratio of fish to bread, satisfying those who crave a heartier meal.
On TikTok, Chef Mike Haracz, a former corporate chef for McDonald’s, endorsed a unique and tasty modification: replacing tartar sauce with Big Mac sauce. In a viral video, he confidently declared, “It’s actually much better with Big Mac sauce, so do that next time.” Such innovative ideas have prompted forays into customizing the beloved sandwich, further solidifying its status in fast food culture.
As the debate around the Filet-O-Fish continues, one thing remains clear. This iconic sandwich not only holds a special place in fast-food history, impacting McDonald’s and the fishing industry, but also brings nostalgia and joy to countless fans. With celebrity endorsements and public engagement, the Filet-O-Fish continues to thrive and evolve as a favorite menu option.
Amid the nostalgia and lively discussions surrounding the Filet-O-Fish, the legacy of Lou Groen and the sandwich he championed persists, reminding us of the impact an innovative idea can have in the fast-food industry.
