A super crisp outer shell wraps around tender cod in this made-from-scratch fish sandwich that puts beach stands to shame. You get all different kinds of crunch and softness with every bite. The buttery, toasted bun holds chilled veggies, a zingy sauce, and flaky fish all together for a meal that's way more than the sum of its parts.
After so many sad, soggy sandwiches at drive-throughs, I had to make one that actually made me happy. I kept tweaking until this version finally impressed my father-in-law—the guy who worked on boats all his life. He said it beat anything "down by the docks."
Must-Have Ingredients
- Cod Fillets: Go for big, nice and white, mild-tasting pieces that fall apart into big flakes when cooked.
- Smoked Paprika: Gives a gentle, smoky flavor boost and a little color without hiding the fish's real taste.
- Club Soda: Makes the batter light and puffy since all those bubbles expand in the hot oil.
- Brioche Bun: Slightly sweet and really soft, they balance out the salty fish and crisp coating.
- Cornstarch: Helps create an epic crispiness on the outside of your fish, trust me on this one.
Making Awesome Fish Sandwiches
- Getting That Batter Right:
- Mix up flour, cornstarch, and your seasonings in a big bowl first. Then add in icy cold club soda but don’t overmix—lumpy batter's actually good, makes for better crunch.
- Oil Heat Check:
- Get your oil steady at 350°F. If it’s too high, you’ll burn the batter before the fish cooks. Too low, and your food sucks up way too much oil.
- How to Fry:
- Before dunking the cod into batter, tap it dry with a towel. Lower it gently into the hot oil. Let it fry to a golden crust on the first side, then give it a flip. This keeps the fish nice and juicy inside.
- Getting the Buns Ready:
- As the fish fries, swipe some butter on your buns and toast them until they’re toasty brown. This gives some crunch and keeps them from getting soggy when you pile everything on.
- Building the Sandwich:
- Start with sauce on the bottom, lettuce on top (that keeps things from getting soggy), then tomato, then hot crispy fish, and finish with a bit more sauce on the lid of the bun.

I picked up this crispy batter trick from my grandma one summer on the coast when I was a kid. She'd always say if it isn't crunchy enough to sound like snow under your boots, it isn't right. That's the crunch you want every time you bite in!
Top Sides to Try
This crispy sandwich goes great with fries tossed in Old Bay, or you can lighten things up by serving a tangy, crunchy coleslaw. Want to go all out? Grab a bowl of clam chowder and you’ve got a full feast.
Tasty Twists to Try
Give it a Cajun kick with a spicy batter, or make it UK-style and serve with a splash of malt vinegar and smashed peas. You can even swap classic tartar sauce for a punchy mango salsa and herby lime mayo for a totally different vibe.
How to Store Leftovers
Honestly, these are best fresh. But if you have leftovers, stick the fish in the fridge for up to 2 days. When you’re ready, toss it in a hot oven (about 375°F) until it’s crispy again.
After lots of trial and error, I’ve realized what really makes this sandwich awesome isn’t expensive fish or wild tricks. It’s just being careful—watching oil temps, drying the fish right, and layering things so you get every bite perfect. One mouthful of this crunchy, steamy sandwich and you’ll seriously start craving more homemade seafood.

Common Recipe Questions
- → How do I make the coating super crunchy?
- Mixing cold club soda and cornstarch makes your batter light so it fries crisp. Don’t forget—hot oil (350°F) is a must.
- → Can I swap out the cod?
- Absolutely! Go for tilapia, haddock, or pollock. Any mild white fish that keeps its shape in the pan is great.
- → What shows me the fish is cooked through?
- If it looks white all the way and breaks apart with a fork, it’s good to go. You want the middle to hit 145°F if you’re checking.
- → Could I skip fried fish and bake it?
- You sure can! Pop battered fillets in a 425°F oven for about 16 minutes, flip halfway. It won’t be as crunchy but it’s still super tasty.
- → What’s a good add-on for this sandwich?
- Fries, chips, slaw, or a quick salad feel right at home here. Splash on malt vinegar if you want that pub vibe too.
