Better Than Tartar Sauce: One Alternative Gives Burger King's Big Fish 50% More Flavor
Burger King is best known for its juicy Whoppers, but the popular fast food chain also sells a delicious fish sandwich called the Big Fish, complete with a crisp Alaskan pollock fillet, pickles, lettuce, and creamy tartar sauce on a fluffy bun. It's easily one of the best fast food fish sandwiches around, but BK fans say swapping sauces makes it extra delicious.
Instead of the Big Fish's typical tartar sauce, swap in Buffalo Sauce for even more flavor. It's bolder and tangier than tartar, with notes of garlic and cayenne pepper that give the sandwich a deep savory flavor and subtle kick of heat. It's also creamy like tartar, but thinner and smoother in texture, meaning your sandwich won't be as thoroughly saturated by sauce. So, if you prefer your fish sandwich with a slightly drier crunch, this swap is perfect.
This Burger King ordering hack can be done in person or online. Simply get the Big Fish without tartar sauce and request Buffalo Sauce packets on the side. Just note that you can't get Buffalo Sauce directly on the sandwich when ordering online, so you'll have to add it yourself.
Other toppings to complement this sandwich
While the Big Fish sandwich sounds delicious this way, try some additional toppings to take it up a notch. Add bacon slices or onion rings for a salty crunch that pairs well with Buffalo's tang. Or, throw on some tomato slices for a light, refreshing twist and jalapeño slices for more heat. Lastly, a slice of American or Swiss cheese might seem controversial — some people think cheese belongs on fish sandwiches, others don't — but its rich taste and texture can cut through Buffalo's bold flavor.
Not a fan of Buffalo? No problem. Try ordering your Big Fish sandwich French-style by swapping tartar with Zesty Sauce instead. This signature BK sauce, made with ingredients like horseradish, egg yolks, tomato paste, and sugar, offers a sharp yet sweet flavor. It won't be as hot as Buffalo sauce, but it still packs quite a punch and spices up your sandwich.
