Let me tell you about this sandwich real quick
I make this Crispy Fried Cod Fish Sandwich when I want that seaside shack feeling without wrangling a parking spot by the pier. The first time I nailed it at home, my brother walked in, sniffed the air, and just said, yup, that. Which is both helpful and not, but the point is the kitchen smelled like summer and a little like victory. I still do a happy little dance when the fillets come out golden and crackly. And alright, tiny confession, I eat the first crunchy edge right over the pan because who is going to stop me.
Strange aside. The last time I bought the cod, the supermarket playlist was all nineties bops and I swear my fish cooked better because I was bopping around. Correlation, causation, who knows.
Why you will love this, or at least why I do
- I make this when the crew is starving and I need dinner fast but fun. Cod fries quickly, and the crunch is a proper crisp, not a half hearted one.
- My family goes a bit mad for the tangy tartar sauce, especially my cousin who claims she does not like mayo. She eats this sauce with a spoon, the rascal.
- It fixes that fried fish craving without a big deep fryer. Also, if the batter looks weird at the start, do not panic, it always does and then it transforms.
- When I am out of buns, I have totally used thick sliced toast and just carried on. No one complained, not even a peep.
- Minor frustration I overcame. Greasy fish. The trick was oil temp and a quick rest on a wire rack. Once I stopped rushing that, boom, light and crisp.
Ingredients, with the honest swaps
Serves 4 hungry folks, or 3 if you are feeling cheeky.
For the fish
- 450 g cod fillets, cut into 4 pieces, about 2 cm thick. Haddock or pollock works when cod is pricey.
- 1 cup all purpose flour, plus 2 tablespoons for dusting. My grandmother swore by a certain brand, but truly any decent flour works.
- 1 tablespoon cornstarch. Sometimes I use rice flour instead if I have it, makes it extra shattery.
- 1 teaspoon baking powder for lift.
- 1 teaspoon kosher salt, plus more to finish.
- 1 teaspoon paprika. Smoked is lovely, sweet is fine.
- 1 cup cold sparkling water. In a hurry, I use plain cold water and a few ice cubes, still good.
- Oil for frying, enough for a shallow pool in your skillet, about 1.5 to 2 cm deep. I like peanut or canola.
For the tartar sauce
- 1/2 cup mayo. If you like making your own, the method on Serious Eats is solid.
- 2 tablespoons finely chopped dill pickles, plus a splash of juice.
- 1 tablespoon capers, chopped a bit.
- 1 teaspoon Dijon mustard.
- 1 tablespoon lemon juice and some zest, about 1/2 teaspoon.
- A handful of chopped fresh dill or parsley.
- Pinch of sugar, pinch of pepper.
For assembly
- 4 soft buns, brioche if you are feeling fancy.
- Butter for toasting the buns, about 2 tablespoons.
- Shredded lettuce, a handful per sandwich.
- Tomato slices, optional. Sometimes I skip it and just go extra pickles.
- Lemon wedges, for spritzing.
How I cook it, with a few casual detours
- Pat the cod dry and season lightly with salt. Let it sit while you prep. I find five to ten minutes helps. If it looks a bit damp again, pat it once more. Moisture is the enemy of crisp.
- Stir together 2 tablespoons flour with a pinch of salt in a shallow bowl. This is your quick dusting station.
- Make the batter. In a bowl, whisk the remaining 1 cup flour, cornstarch, baking powder, paprika, and 1 teaspoon salt. Pour in the cold sparkling water and whisk just until combined. Lumpy is fine, actually I find it works better if you do not over whisk.
- Dredge each piece of cod in the light dusting of flour, shake off excess. Then dip into the batter and let the extra drip. This is where I usually sneak a taste of batter on my fingertip, which is unhelpful but honest.
- Heat oil in a wide skillet over medium to medium high. A thermometer is great here, aim for about 180 C. If you do not have one, drop in a crumb of batter, it should sizzle energetically and rise in a second or two. The Kitchn has a handy read on oil temps if you are curious, see their guide.
- Carefully lay in two pieces of fish. Do not crowd the pan. Fry about 3 to 4 minutes per side until deeply golden and crisp, turning once. Adjust the heat as needed so it bubbles but does not smoke. If it gets too dark, lower the heat and breathe.
- Transfer fried fish to a wire rack set over a baking sheet and sprinkle with a tiny pinch of salt. Keep warm in a low oven, about 95 C, while you fry the rest. If you put it straight on paper towels it can steam and soften, which makes me a bit sad.
- Toast the buns in a little butter in a separate pan until golden. Or toss them under the broiler for a minute, but watch closely, they go form perfect to charred fast.
- Mix the tartar sauce while the last batch is frying. Stir everything together and taste. Add more pickle juice if you like it punchier. I do.
- Build the sandwiches. Bottom bun, swipe of tartar, pile of lettuce, hot crunchy cod, more tartar, tomato if using, squeeze of lemon, top bun. Press gently so the sauce hugs the fish. Eat immediately, it is happiest when its ready and you are too.
Notes I learned the hard way
- Cold batter plus hot oil equals crisp. If the batter warms up, toss in an ice cube for a minute, fish it out, keep going.
- Flour choice matters a little. All purpose is reliable. I tried cake flour once and it went too tender. If you want to nerd out, the info on protein levels at King Arthur Baking is helpful.
- Resting on a rack is not just restaurant drama. It keeps the underside from getting soggy while the steam escapes.
- Slice the fillets so they are about the same thickness, even if that means two smaller pieces in one sandwich. Even cooking is worth the extra minute of trimming.
Little experiments and a couple oops
- Beer batter. Swapped the sparkling water for a cold pale ale. Lovely flavor and color, slightly thicker crust. A crowd pleaser.
- Air fryer test. Lightly dusted fish in seasoned flour, spritzed with oil, 200 C for about 10 to 12 minutes flipping once. Not as shatter crisp as frying but still tasty and tidy.
- Whole wheat flour. I wanted nutty flavor, but it made the crust heavy. Would not do again for this sandwich.
- Panko double dip. Flour, batter, then a sprinkle of panko before frying. Very crunchy, a bit extra effort, but on second thought worth it for guests.
Gear I use, and what to do if you do not have it
- Wide heavy skillet. Cast iron is my friend for even heat. A regular nonstick pan works too, just keep the heat moderate.
- Instant read thermometer. I say it is essential for perfect fry oil, then I eyeball it by the sizzle when I am feeling brave. Do what you can.
- Wire rack and sheet pan. If you do not have a rack, prop the fish on two chopsticks laid across a plate. Works a treat.
- Tongs. Or a slotted spoon if that is what you have.
How to stash leftovers
Let cooked fish cool, then refrigerate in a covered container with paper towel underneath for up to 2 days, though honestly, in my house it never lasts more than a day. To reheat, pop on a rack in a hot oven at 200 C for 8 to 10 minutes until crisp again. I think the sauce tastes even better the next day, but that might just be me.
Serve it like this and you will be chuffed
- A heap of salt and vinegar fries on the side, or a crunchy slaw if you are feeling sensible.
- Extra lemon wedges and hot sauce on the table. My aunt likes a tiny drizzle of honey, which sounds odd, but it plays nice with the vinegar pickles.
- Family tradition here. We wrap the sandwiches in parchment for two minutes before serving. It warms the bun and sort of melds everything together.
Pro tips, learned by messing up
- I once tried rushing the oil preheat and regretted it because the fish soaked up oil and turned floppy. Give the pan time, then test with a crumb.
- Another time I stacked the finished fillets on a plate. Steam city. The bottom went soft. Rack resting is the move.
- Season the fish lightly before batter. When I skipped that, the inside tasted flat even though the crust was seasoned.
- Do not overwork the batter. I whisked it smooth once and lost the craggy bits that get extra crisp, which is half the fun.
Frequently asked questions, straight from my inbox
Can I use frozen cod
Yes, just thaw fully and pat very dry. If there is ice or water on the fish, the batter will slide off and you will be cross about it.
What if I do not eat mayo
Try a quick yogurt and pickle sauce, same mix otherwise. It is tangier, which I like, but maybe add a splash of olive oil for richness.
How do I keep the batter from falling off
Dry fish, light flour dusting, then into cold batter, then straight into hot oil. Also, do not poke it in the first minute. Let the crust set. Hands off, y’all.
Which oil is best for frying
Neutral and high smoke point. Peanut is my favorite, canola is great, sunflower works. If the oil smells old, toss it. Reused oil can taste off.
Can I bake instead
You can, but it is a different vibe. Brush fish with oil, coat in seasoned panko, bake at 220 C until crisp, about 12 to 15 minutes. Nice, but not the exact same crunch as this Crispy Fried Cod Fish Sandwich.
Is cod the only fish that works
Nope. Haddock, pollock, even tilapia in a pinch. Choose fillets that are not too thin so they stay juicy inside.
A couple links I actually use
- Frying safety and technique basics at Serious Eats. Clear and calm.
- Flour talk and protein levels at King Arthur Baking. Nerdy in the best way.
If you make this, send me a photo, or just tell me if your bun slipped because you went extra on the tartar. I do the same, no shame. Cheers.
Ingredients
- 4 cod fillets (about 1 lb / 450 g), skinless and boneless
- 1 cup all-purpose flour
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 2 large eggs
- 1/2 cup milk
- 1 1/2 cups panko breadcrumbs
- 1 cup vegetable oil (for frying)
- 4 brioche buns, split and toasted
- 1 cup shredded lettuce
- 1/2 cup tartar sauce
Instructions
-
1Prepare the fish: Pat cod fillets dry with paper towels and season both sides with salt and pepper. Cut fillets into portions that fit the buns if needed.
-
2Set up a breading station: place flour in one shallow dish, whisk eggs with milk in a second bowl, and put panko breadcrumbs in a third dish. Dredge each fillet in flour, shake off excess, dip into the egg mixture, then press into panko to coat evenly.
-
3Heat oil in a large skillet over medium-high heat to about 350°F (175°C). Add enough oil to cover the bottom of the pan about 1/4–1/2 inch deep. Fry the breaded fillets for 3–4 minutes per side, or until golden brown and cooked through (internal temperature 145°F / 63°C). Transfer to a paper towel-lined plate to drain.
-
4Toast buns lightly. Spread tartar sauce on the bottom halves of the buns, add shredded lettuce, place a fried cod fillet on each, and top with the remaining bun halves. Add pickles or lemon wedges if desired.
-
5Serve immediately while hot and crispy. Optionally serve with fries, coleslaw, or extra tartar sauce on the side.
