The McDonald's Filet-O-Fish Hack That Leads To A Bigger Sandwich

We've been to a lot of drive-thrus and tried many of the best McDonald's Filet-O-Fish hacks for fresh spins on this classic seafood sandwich, but one rises above the rest — literally. For not much extra cash, you can add extra fish patties to create a meatier, more satisfying sandwich that helps you stay full longer. Like many word-of-mouth hacks that we've uncovered, we owe this top-secret tip to Reddit: In the midst of an unrelated discussion on Burger King's Fiery Big Fish, a commenter let it slip that they eat big fish sandwiches at McD's simply by ordering an extra patty on a double Filet-O-Fish for a triple-stacked fish fiesta. You just have to be willing to engage in the simple hack of ordering an attention-grabbing amount of fish.

Alaskan pollock is the type of fish McDonald's uses in the Filet-O-Fish, and its mild taste lends itself to deliciousness when stacking patties. Namely, you aren't overwhelmed with "fishiness," and you can more readily enjoy the heft of a handheld that has, in some folks' opinions, a better protein-to-bun ratio. As a further plus, a double Filet-O-Fish comes with two half-slices of cheese, which can do wonders for your sandwich's bulk and intensity of flavor. You can even ask for more cheese and sauce.

The Filet-O-Fish is easy to jazz up with customizations, and the opportunities to make this order your own are only amped up with more fish patties. For example, we've long used one Filet-O-Fish bun swap by requesting an English muffin in place of a steamed bun. Since an English muffin is a heftier bread product, the additional fish really makes an impact in this modified sandwich. Same goes for subbing Big Mac sauce for the normal tartar sauce: It's tangier, and the extra helpings of protein really balance those sauce-fish ratios in a satisfying manner. There's no reason you can't swap out the tartar sauce for most of McDonald's beloved sauces, actually; we're not completely on board with barbecue, but sweet and sour can add a kick to your whitefish and honey mustard is a match made in heaven.

With three — or more — fish patties, you get a mighty specimen of a Filet-O-Fish that's worthy of a snap on social media and that might even require two hands to consume. There's basically no end to all the ways you can enjoy a beefed-up (fished-up?) Filet-O-Fish, so long as you're pretty darn hungry at the start.
