Ingredients Notes

The real magic of this cod sandwich lies in using simple ingredients with a few clever touches. Every component matters, from the fish to the breading, so here’s a closer look at what makes this recipe shine.

Cod fillets are the star of the show. Look for fresh or thawed wild-caught cod, which tends to have a mild, clean flavor and flaky texture. If your fillets are on the thicker side, consider slicing them lengthwise to help them cook evenly and fit better on your buns.

Buttermilk plays an important role in tenderizing the fish and helping the breading adhere. A quick soak adds flavor and helps lock in moisture during frying. If you don’t have buttermilk, you can make a substitute using milk and a splash of vinegar or lemon juice.

Panko breadcrumbs are essential for that ultra-crispy coating. These Japanese-style breadcrumbs fry up lighter and crunchier than regular ones. I like to season them with a mix of paprika, garlic powder, and black pepper for a flavorful punch.

Brioche or potato buns are ideal for holding everything together. Their soft, slightly sweet texture pairs beautifully with the salty, crispy fish. Toast them lightly for extra structure and a touch of golden color.

You’ll also need a good skillet or Dutch oven and a thermometer for checking oil temperature. A wire rack for draining the fried fish helps preserve that crispy crust, so don’t skip it if you can help it.

How To Make This Crispy Fried Cod Fish Sandwich

This recipe is all about building layers of flavor and texture, and each step brings you closer to that perfect sandwich moment.

Start by soaking the cod fillets in buttermilk for at least 15 minutes. This step is quick but crucial—it not only tenderizes the fish but also helps the breadcrumbs cling for a better crust.

While the fish is soaking, prep your breading station. In one shallow bowl, mix flour with a bit of salt and pepper. In a second bowl, whisk an egg. In a third, combine seasoned panko breadcrumbs with garlic powder, paprika, and a pinch of cayenne for a hint of heat.

Dredge each fillet first in the flour, then in the egg, and finally press it firmly into the breadcrumb mixture to fully coat. Make sure the coating sticks well—this is what gives you that glorious golden crunch.

Heat your oil in a deep skillet or Dutch oven to 350°F. Carefully add the breaded fillets and fry them for 3 to 4 minutes per side, depending on thickness, until deeply golden and crispy. Work in batches so the temperature stays consistent and each piece gets evenly cooked.

Transfer the fried fish to a wire rack set over a baking sheet to drain. This keeps the crust from going soggy. While the fish rests, toast your buns lightly in a skillet or under the broiler for just a minute or two.

Assemble the sandwiches by spreading tartar sauce on the bottom bun, adding a piece of crispy cod, and topping it with shredded lettuce, tomato slices, or pickles—whatever toppings you love most.

The whole process takes around 30 to 35 minutes, start to finish. What you get is a sandwich that’s hot, crispy, and irresistibly satisfying.

Storage Options

If you have leftovers (though that’s a big if), they can be stored easily for a next-day treat.

Wrap any leftover fried cod in foil or place it in an airtight container. It will keep in the refrigerator for up to 2 days. To preserve the crispy texture, don’t add any condiments or toppings before storing.

For longer storage, you can freeze the cooked, cooled fish fillets. Place them on a parchment-lined tray in the freezer until solid, then transfer to a zip-top freezer bag. They’ll keep well for about 1 month.

When reheating, avoid the microwave, which will make the breading soggy. Instead, place the fish on a baking sheet in a 375°F oven for 10–12 minutes until heated through and crisp again.

Reassemble your sandwich with fresh toppings and enjoy it like it’s freshly made.

Variations and Substitutions

One of the best things about this fried cod sandwich is how flexible it is. With a few tweaks, you can make it suit your dietary needs, spice preferences, or whatever you have in the fridge.

For a spicy twist, add cayenne to the breadcrumb mixture or drizzle with hot sauce before serving. You could even swap in a spicy remoulade for the tartar sauce.

Prefer a lighter option? Skip the frying and try oven-baking the breaded fillets at 425°F for 15–18 minutes, flipping halfway through. You’ll still get a great crust with a little less oil.

If cod isn’t available, try haddock, pollock, or tilapia. All have mild flavors and similar textures that work beautifully in this recipe.

Looking to go dairy-free? Use plant-based milk with lemon juice instead of buttermilk and check your buns for dairy ingredients. The sandwich will still be wonderfully crisp and tasty.

And of course, you can get creative with toppings. Add coleslaw, arugula, red onion, or a slice of cheese to build your perfect version.

Have fun with it—once you’ve mastered the basics, the possibilities are endless.
