What’s In Our BK Big Fish Sandwich?

Burger King uses Alaskan Pollock fillet for their fish sandwich, which is also used in several fast-food chains and restaurants. In this recipe, we used cod fillet which is the best substitute for Alaskan Pollock. Both are great with frying, baking, sauteing, and steaming. But you can totally use other fish of your choice in recreating this copycat recipe. Check out our CAQ section for other types of fish you can use.

If you’re wondering what made our fish sandwich so close to BK’s, let’s talk about the delicious ingredients that made our sandwich epic.

  • Crunchy fish fillet – In this recipe, we aimed to get that savory taste and a crunchy texture on our fish burger. So we’re coating our fish fillet through seasoned flour, then roll them into some lightly whisked egg with milk and cover the fillets through breadcrumbs.
  • Filling – We highly recommend that you use iceberg lettuce and cheese in addition to your fish meat. This salty-sweet and refreshing combination of leafy veggie and seafood meat will give you a juicy and fresh blast of flavor in every bite.
  • Tartar sauce – The tartar sauce on the other hand tastes mild, creamy, and tangy. It blends perfectly on the dry and salty taste of the fried fish. It’s made with simple ingredients that you most likely have in your kitchen.
Tip: Toast your hamburger buns to your own liking. You might want it a little burnt or soft, it’s totally up to you.

All in all, we’re sure you’ll savor each and every bite of this fried fish sandwich once you make it. For a full-on Burger King meal, you might want to try serving this sandwich with BK Chicken Nuggets crunchy fries or onion rings and a bottle of soda.
