What Kind of Fish Fillet Should I Use?

Cod is ideal for its mild flavor and flaky texture, which crisps up beautifully when fried. You can also use haddock, pollock, or another firm white fish, but cod holds shape well and has the perfect size for sandwich building.

Ingredients for the Crispy Fried Cod Sandwich

Cod Fillets
The star of the show. Cod’s mild taste and flaky structure make it perfect for frying and tucking into buns.

Buttermilk
Adds tang and helps the seasoned flour stick better for a crispy crust.

Flour + Cornstarch Mix
Creates the golden, crunchy coating. Cornstarch lightens the texture while flour adds structure.

Seasonings (Garlic powder, Paprika, Salt, Pepper)
To give the coating a delicious savory punch.

Oil for Frying
A neutral oil like canola or vegetable ensures the coating gets extra crisp without overpowering the fish flavor.

Brioche or Pretzel Buns
Soft yet sturdy enough to hold everything together, and slightly sweet or salty to complement the fish.

Tartar Sauce
Creamy, tangy, and herbaceous—a must-have for cutting through the fried richness.

Lettuce, Tomato, Red Onion, Pickles
Fresh toppings add crunch, juiciness, and brightness to balance out the fried cod.

How To Make the Crispy Fried Cod Sandwich

Step 1: Prepare the Cod

Pat the cod fillets dry with paper towels to remove excess moisture. This helps the coating stick and crisp up during frying.

Step 2: Marinate in Buttermilk

Place the cod in a shallow dish and pour the buttermilk over it. Let it soak for at least 30 minutes in the fridge to tenderize and infuse flavor.

Step 3: Mix the Dredge

In a separate bowl, combine the flour, cornstarch, garlic powder, paprika, salt, and pepper. Mix well.

Step 4: Coat the Fish

Remove the cod from the buttermilk and let excess drip off. Dredge each fillet in the flour mixture, pressing lightly to adhere. Set aside on a tray.

Step 5: Fry to Crispy Perfection

Heat oil in a skillet or deep fryer to 350°F (175°C). Fry the cod fillets in batches for about 3–4 minutes per side or until golden brown and cooked through. Transfer to a wire rack to drain.

Step 6: Toast the Buns

While the fish drains, lightly butter the buns and toast them in a skillet or under a broiler until golden.

Step 7: Assemble the Sandwich

Spread tartar sauce on the bottom bun, layer with fried cod, lettuce, tomato slices, red onion, and pickles. Cap with the top bun and serve warm.

How to Serve and Store Your Crispy Fried Cod Sandwich

Serve the crispy fried cod sandwich hot, ideally right after assembling so the fish remains crisp and the bun stays toasty. It pairs beautifully with classic sides like seasoned fries, coleslaw, or even a fresh cucumber salad.

For storing, keep the components separate. Store leftover fried cod in an airtight container in the refrigerator for up to 2 days. Reheat in the oven or air fryer to retain crispiness. Avoid microwaving as it makes the coating soggy.

Frequently Asked Questions

Can I use frozen cod fillets?

Yes, but make sure they are completely thawed and patted dry before marinating to avoid soggy coating.

What can I use instead of buttermilk?

You can mix 1 cup of milk with 1 tablespoon of lemon juice or vinegar and let it sit for 10 minutes.

How do I know when the fish is done frying?

The cod should be golden brown and flake easily with a fork. Internal temperature should reach 145°F (63°C).

Can I bake the cod instead of frying?

You can, but the texture won’t be as crispy. Bake at 425°F for 12-15 minutes, flipping halfway through.

What’s the best bun for this sandwich?

Brioche or pretzel buns work best—they’re soft but sturdy enough to hold the crispy cod and toppings.

Can I make this gluten-free?

Yes, just use gluten-free flour and buns. Make sure your seasonings and cornstarch are also certified gluten-free.
