This upgraded Fish Sandwich turns fresh cod into a golden, crunchy delight that beats any fancy restaurant version. The mix of well-seasoned fish, homemade tartar sauce, and soft brioche buns makes a sandwich that blends down-home comfort with fancy food vibes.
I've spent years getting this just right in my kitchen, and I've found the magic comes from double-coating the fish and watching the heat closely. Now my family asks for these sandwiches instead of getting takeout.
Premium Ingredient Lineup
- Cod fillets: Go for chunky, solid pieces to get the best outcome
- Peanut oil: Handles high heat for cleaner frying
- Old Bay Seasoning: Gives that perfect taste of the sea
- Sparkling water: Creates an airy, crisp coating
- Fresh parsley: Brings life to your tartar sauce
- Dill pickles: Adds just the right zip to your sauce
- Brioche buns: Offers a buttery base for your fish
Crystal Clear Cooking Guide
- Whipping Up Tartar Sauce:
- Chop pickles and capers small. Stir mayo till creamy. Throw in other stuff bit by bit. Add salt and pepper how you like. Let it sit while you deal with the fish.
- Getting Oil Just Right:
- Warm oil gradually so it doesn't get too hot. Keep it steady at 375°F. Use a deep, solid pot. Stick a thermometer on the side. Turn heat up or down as you need.
- Getting Fish Ready:
- Slice fish into same-sized chunks. Dry them completely with paper towels. Add plenty of seasoning. Let them warm up a bit. Set up your coating stuff.
- Coating Your Fish:
- Roll in seasoned flour. Tap off extra. Dunk fully in batter. Let extra drip away. Put straight into hot oil.
- Proper Frying Method:
- Slip fish into oil carefully. Don't crowd too many pieces in. Flip just once while cooking. Watch the color and bubbling. Dry on a wire rack.

This all started when I tried to copy my grandpa's famous fish fry, and it's grown into something I think he'd enjoy even more than his own.
Heat Control Tips
After tons of testing, I've learned that keeping oil at the same temperature really matters. I clip a candy thermometer to my pot and tweak the burner as needed. When oil gets too hot, the outside burns before the fish cooks inside; too cool and your fish soaks up grease like a sponge.
Prep-Ahead Tricks
While fresh-fried fish can't be beat, I often get stuff ready beforehand. The tartar sauce actually tastes better after sitting overnight. I also mix the dry coating ingredients and store them apart, which makes cooking day so much faster.
Picking The Perfect Bun
The bun choice really changes everything. After trying loads of options, I've found brioche gives you just the right mix of sturdiness and softness. A quick steam adds moisture but keeps them fluffy.
Mix Up Your Sauce
I've played around with lots of additions to my tartar sauce. Throwing in some chopped shallots adds extra tang, while fresh dill makes it more herby. If you want some kick, a bit of cayenne or finely diced jalapeños works great.
What To Serve Alongside
These sandwiches go great with classic sides. I love them with crunchy coleslaw, homemade fries, or a bright citrus salad. When friends come over, I set out a bunch of toppings so everyone can make their sandwich their own.
Dealing With Extras
Though best right after cooking, leftover fish can go in a 350°F oven until it crisps up again. I keep the tartar sauce in a separate container and always make extra - it's awesome on other sandwiches too.

These Fish Sandwiches have turned into my go-to comfort food, something folks ask for at everything from casual family dinners to weekend get-togethers. The mix of crunchy fish and tangy homemade sauce creates something really special that brings everyone to the table. Whenever I make them, I'm reminded that sometimes the simplest foods, made with a little extra care, become the meals we treasure most.
Frequently Asked Questions
- → How do I get super crunchy fish?
- Using the flour-then-batter method and keeping your oil steady at 375°F will give you that perfect crunch factor.
- → Can I prepare the sauce earlier?
- Definitely. You can make the sauce up to 3 days before and keep it in the fridge. It gets even tastier as it sits.
- → What's the point of using fizzy water?
- The bubbles create a lighter, crunchier coating when you fry it. A light beer works too if that's what you have.
- → Is it okay to use fish from the freezer?
- Sure thing. Just let it thaw completely and pat it really dry before adding the batter so it turns out crispy.
- → What's special about steaming the buns?
- Steaming makes them super soft and fluffy, just like the ones from restaurants. It also helps the cheese melt nicely.
