Fried Mahi-Mahi Fish Sandwich (AKA: Ultimate Filet-O-Fish)

It’s no secret to long-time readers of this website that I have a deep-seated, lifelong obsession with the McDonald’s Filet-O-Fish. I understand the consequences of voicing this passion publicly, understand that every time I mention the sandwich, another self-appointed “foodie” rolls his eyes in disgust, and goes back to the dictionary to find a new way to use the word “unctuous.”

Fried Mahi-Mahi Fish Sandwiches Topped with Cheesy Curly Fries

Here’s the gamble: I’ve always been willing to bet that for every miso-scented prig who Alt-F4s this website in disgust, vowing never to return again and to instead get back to the very important business of name-dropping their butcher in unrelated conversation, there’s at least one other person cheering us on. Someone with a whole head full of common sense. Someone with $3.13 burning a whole in their pocket. Someone who knows that there are few moments more rewarding in life than the second you discover that your piping hot Filet-O-Fish was made fresh to order, just for you. It’s enough to change the trajectory of your whole day, enough to turn a lousy day at work or a fight with your wife into a tiny moment of personal reverie.

Fried Mahi-Mahi Fish Sandwiches Topped with Cheesy Curly Fries

A soft, steamed bun, a crunchy mishmash of pollock, a heavy dose of tartar sauce, and an inexplicably half-melted slice of American cheese. It’s paradise on a bun, and I know that there are more people that accept that, than deny it.

Fried Mahi-Mahi Fish Sandwiches Topped with Cheesy Curly Fries

For this sandwich, I wanted to honor the uniquely American combination of flavors, textures, and ingredients native to the Filet-O-Fish, and then ratchet them up to levels of gluttony that are enough to make you pick up the phone after it’s all over to call your dad and tell him what you’ve done. The thinking was simple: If minced pollock is good, an entire mahi-mahi, cod, or haddock fillet would be even better. We added a layer of lettuce and tomato to bring both moisture control and juiciness, respectively. Or friends in jolly old England inspired the addition of a layer of french fries, and the cheese sauce? Well, if a slice of processed, pasteurized American cheese was good enough for the Filet-O-Fish, an entire river of molten cheese sauce over the whole thing would be even better.
