You’ll get super crunchy fish under a crisp shell that breaks with every bite. Inside, the cod turns tender and flaky, all tucked in a warm, toasted bun. There’s fresh veg and tangy sauce packed in too. Simple stuff, but the way it all comes together just hits different.
After being let down by drive-thru fish sandwiches for years, I rolled up my sleeves to nail the best one myself. Dozens of kitchen experiments later, this is the version that finally made my father-in-law—the lifelong fisherman—say it’s “even better than what you’ll find at the docks.”
Incredible Ingredients
- Brioche Buns: Slightly sweet and buttery, these hold up under all that crunch and sauce.
- Smoked Paprika: Sneaks some depth and color into the crust, but doesn’t cover up the cod’s mild flavor.
- Club Soda: Fizz adds tiny bubbles, making the batter puff up and get super airy in hot oil.
- Cornstarch: The real trick for extra crispiness in every bite.
- Fresh Cod Fillets: Grab thick, white pieces—they cook up flaky and melt-in-your-mouth tender.
Building Awesome Fish Sandwiches
- Strategic Assembly:
- Spread sauce over your bottom bun first, then lettuce to keep sogginess away, followed by tomato slices, fish, and a nice smear of sauce on the top bun.
- Bun Prep:
- Butter and toast your buns while the fish cooks, so the bread gets golden and doesn’t get mushy from toppings.
- Frying Technique:
- Make sure cod is totally dry before you batter it. Lower gently into oil and let one side brown first—gives the fish a crunchy, locked-in shell.
- Managing Oil Heat:
- Hold your oil right at 350°F. Go hotter and things burn before the insides cook; colder and you’ll get oily, limp batter.
- Batter Time:
- Mix flour, cornstarch, and seasoning in a bowl, then start whisking in ice-cold club soda. Lumps are fine—don’t stir too much, or the crust will end up chewy.

When I was twelve, my grandma showed me this batter trick at her house by the water. She always said, 'A real fish sandwich should crunch like new snow'—and she was totally right.
Tasty Sides
Scoop up some old-school French fries dusted in Old Bay, or go with a zippy vinegar slaw on the side. Want a real seafood spread? Serve up a mug of creamy New England clam chowder too.
Tasty Twists
Spice things up with Cajun flavor—just add cayenne and blackening spice to your batter. Want it Britain-style? Splash on malt vinegar and do mushy peas. Go island-style with mango salsa and a cilantro-lime mayo swap for the usual tartar.
Keeping Leftovers Good
These sandwiches are best eaten right after you make them. Got extra fried fish? Stick it in the fridge for up to two days. Reheat in a 375°F oven until it’s hot and crispy again.
Here’s what I’ve learned after all these attempts: details matter way more than fancy tricks. Holding the right oil temperature, getting the build just right, and not skipping steps? It upgrades simple stuff to something amazing. Seriously—one crunchy, flaky bite and you’ll feel like you’ve opened your own seafood spot at home.

Recipe Questions & Answers
- → Why is this fish so crunchy?
- Cornstarch with ice-cold club soda gets you a super light, bubbly batter. Have your oil hot at 350°F so it fries right.
- → Could I switch what fish I use?
- Absolutely. Tilapia, haddock, or pollock hold up great. Just pick a mild, firm white fish.
- → How’s the fish supposed to look when it’s cooked?
- Check if it’s turned opaque and flakes with a fork—also, it’s done at 145°F inside for safety.
- → Is there a way to do this besides frying?
- You can bake it instead, 425°F for about 15 to 18 mins and flip once. It’s not as crunchy, but still really good.
- → What can I eat alongside this sandwich?
- Go for chips, fries, coleslaw, or a little salad. For some extra flair, try malt vinegar on the side.
