Once you've had this sandwich fresh out of the pan, you’ll wonder why you ever ordered it out. Let’s look at what you’ll need to make it happen.

Ingredients Notes

What makes this sandwich shine is its simplicity—just a handful of key ingredients come together to create something truly memorable.

Fresh cod fillets are the star of the show. Look for firm, flaky pieces that are about ½ to 1 inch thick. Fresh is best, but frozen cod works too—just make sure to fully thaw and pat dry before breading to avoid sogginess.

Buttermilk is essential for tenderizing the fish and helping the breading stick. If you don’t have buttermilk on hand, you can make a quick version with milk and a splash of vinegar or lemon juice.

Flour and cornmeal form the crispy coating. The flour gives structure while the cornmeal adds texture and crunch. I like to season this mixture with a blend of paprika, garlic powder, salt, pepper, and just a touch of cayenne for subtle heat.

Brioche or potato buns are my favorite for this sandwich. Their soft, slightly sweet flavor pairs beautifully with the savory fish and holds up well to sauces and toppings.

You won’t need much equipment—just a heavy-bottomed skillet or cast iron pan, a wire rack for draining, and a few shallow bowls for dredging. A fish spatula is helpful too, but not required.

How To Make This Crispy Fried Cod Fish Sandwich

Making this sandwich is simpler than you might expect. Once you’ve prepped your ingredients, everything moves quickly.

Start by patting your cod fillets dry with paper towels. This step is key to getting a good sear and ensuring the breading sticks. Slice them into bun-sized pieces if needed.

Next, mix together your seasoned flour and cornmeal coating in a shallow dish. In another bowl, pour your buttermilk. Dip each piece of cod into the buttermilk, letting the excess drip off, then dredge in the flour mixture, pressing lightly so the coating adheres well.

Heat about half an inch of oil in a skillet over medium-high heat. You'll know it's ready when a small piece of coating sizzles immediately upon contact. Carefully place the coated cod in the pan, working in batches if necessary. Fry each piece for about 3–4 minutes per side, until golden brown and crisp.

Transfer the fried fish to a wire rack set over a baking sheet. This prevents the bottom from getting soggy while you prep the buns and toppings.

While the fish rests, lightly toast your buns in the skillet or under the broiler. This adds a bit of texture and helps them hold up to the fillings.

Assemble your sandwich: bun, sauce (tartar, slaw, or spicy mayo), fried cod, maybe some lettuce or pickles, and top with the other half of the bun. Serve immediately while the fish is still warm and crispy.

Total time? About 30 minutes from start to finish—and it tastes like a coastal vacation in your kitchen.

Storage Options

This sandwich is best served fresh, but you can definitely prep parts of it ahead.

If you have leftover fried cod, store it in an airtight container in the fridge for up to 2 days. Place a paper towel underneath to absorb excess moisture and help keep it crisp.

To reheat, avoid the microwave—use a toaster oven, air fryer, or skillet to bring back the crunch without overcooking the fish.

You can also prep and freeze the breaded, uncooked fillets. Just lay them out on a baking sheet and freeze until solid, then transfer to a freezer bag. Cook directly from frozen, adding a couple of extra minutes per side.

Assembled sandwiches don’t hold up well in the fridge, so store components separately and assemble just before eating.

Variations and Substitutions

One of the best things about this crispy cod sandwich is how adaptable it is. There’s plenty of room to play based on what you have on hand or your personal taste.

If you can’t find cod, try haddock, pollock, or even tilapia. Any mild white fish with a firm texture will work beautifully.

For a gluten-free version, swap in a gluten-free flour blend and use gluten-free buns. The cornmeal adds a great crunch even without traditional flour.

Want more heat? Add extra cayenne to the breading, or spread a layer of spicy remoulade or sriracha mayo on the bun.

Toppings are totally customizable. Classic tartar sauce is always great, but I love adding a scoop of vinegary slaw for crunch and brightness. Sliced pickles, shredded lettuce, or thin tomato slices also work well.

Don’t be afraid to turn this into sliders or even a fish taco by switching out the bun for a tortilla. The fried cod works beautifully in all kinds of formats.
