This next-level Fish Sandwich turns fresh cod into a golden, crunchy delight that beats any dining out 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 touches.

I've spent so many nights tweaking this in my kitchen, and I've found the magic happens with double-coating the fish and watching the heat carefully. My kids now beg for these instead of fast food fish sandwiches.

Key Ingredients Breakdown

  • Cod fillets: Go for chunky, solid pieces for the best outcome
  • Peanut oil: Won't burn when hot, giving cleaner frying results
  • Old Bay Seasoning: Brings that perfect seafood kick
  • Sparkling water: The secret to an airy, crispy coating
  • Fresh parsley: Gives the tartar sauce its needed brightness
  • Dill pickles: Creates that must-have tang in the sauce
  • Brioche buns: Adds a buttery softness against the crunchy fish

Simple Cooking Instructions

Whipping Up Tartar Sauce:
Chop pickles and capers small. Stir mayo until creamy. Throw in all bits gradually. Add salt and pepper to taste. Let it sit while you work on the fish.
Getting Oil Ready:
Warm oil gradually to keep it stable. Keep it steady at 375°F. Pick a deep, sturdy pot. Stick thermometer on the side. Turn heat up or down as you go.
Getting Fish Ready:
Slice fish into same-sized chunks. Wipe away all moisture. Sprinkle plenty of seasoning. Allow to warm slightly. Set up your coating stations.
Coating Your Fish:
Roll in spiced flour. Tap off the extra. Dunk fully in batter. Let drips fall off. Go straight to the hot oil.
Frying It Up:
Drop fish into oil with care. Keep some space between pieces. Flip just once while cooking. Watch the bubbles and color. Rest on wire rack after.

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 original.

Oil Heat Tricks

After tons of test batches, I can tell you that keeping your oil at the right heat is everything. I clip a candy thermometer to my pot and fiddle with the burner as needed. When oil gets too hot, your coating burns before the fish cooks inside. Too cool, and you'll end up with oily, soggy fish.

Prep-Ahead Options

The fish tastes best when fried on the spot, but I often get other stuff ready ahead. The tartar sauce actually gets tastier if it sits in the fridge overnight. I also mix up the dry coating ingredients and keep them in containers, which saves time when I'm ready to cook.

Picking The Perfect Bun

Your choice of bun really matters here. After trying loads of options, I've landed on brioche as the winner with its perfect mix of sturdiness and softness. A quick steam before serving adds just enough moisture while keeping them fluffy.

Switching Up Your Sauce

I've played around with lots of add-ins for the tartar sauce over time. Tiny chopped shallots give it extra tang, while fresh dill makes it more herby. If you like spice, throw in some cayenne or finely diced jalapeños for a nice kick.

What To Serve With It

These sandwiches go great with classic sides. I usually make some crunchy slaw, homemade fries, or a bright citrus salad to go alongside. When friends come over, I set out a bunch of toppings so everyone can dress up their sandwich just how they want.

Using Up Extras

Though they're best fresh, you can warm leftover fish in a 350°F oven until the crunch comes back. I always keep the sauce separate and make extra because it's amazing on other sandwiches too.

Frequently Asked Questions

→ How do I make the fish super crispy?
Double-coat it by using flour and the batter, and keep the oil hot at 375°F. That crunch depends on it!
→ Can tartar sauce be prepped early?
Yep, make it up to 3 days ahead and store in the fridge. It actually tastes better after sitting for a bit.
→ What does sparkling water do for batter?
It makes for a super light and crispy texture. Light beer can swap in if you don't have sparkling water.
→ Can frozen fish be used?
Absolutely! Just thaw it fully and pat it dry so the coating sticks well and crisps up right.
→ Why steam the buns?
Soft, warm buns—just like the original. Plus, it helps melt the cheese perfectly.

Ingredients

→ Fish

01 Cod like Icelandic type or similar (1½ pounds)
02 Season with pepper and salt

→ Dry Coating

03 1 cup of plain flour
04 ½ tablespoon of Old Bay mix

→ Wet Batter

05 Another 1 cup of plain flour
06 1 full tablespoon of Old Bay spice
07 A half tablespoon of smoked paprika
08 1 small teaspoon of turmeric powder
09 ½ teaspoon of ground white pepper
10 ½ teaspoon baking powder
11 1 egg, cracked
12 1 cup of sparkling water
13 Pepper and salt to taste

→ Sauce for Sandwich

14 ½ cup mayo
15 3 tablespoons finely chopped dill pickles
16 1 tablespoon of capers, minced
17 1 tablespoon of freshly chopped parsley
18 1 tablespoon fresh lemon juice
19 2 teaspoons Dijon mustard
20 Pepper and salt for seasoning

→ For Cooking and Serving

21 2 quarts peanut or neutral oil for frying
22 4 sandwich rolls or burger buns
23 2 cheddar cheese slices, cut in half

Instructions

Step 01

Using a deep, heavy pan, bring the frying oil to 375°F. Keep it hot during cooking.

Step 02

Stir mayo, pickles, parsley, capers, mustard, and lemon juice together in a bowl. Add salt and pepper for flavor.

Step 03

Slice cod into squares to fit the buns (around 4-6 ounces each). Sprinkle with salt and pepper, then set on a wire rack placed above a pan.

Step 04

Mix flour with Old Bay seasoning in one shallow bowl for the dry coating. In another bowl, combine the rest of the flour, spices, baking powder, egg, and sparkling water to make the wet batter. It should look like a thin salad dressing.

Step 05

Dip each fish piece into the dry mix first, then cover it in the wet batter. Let any extra batter drip back into the bowl.

Step 06

Fry the fish for about 2-3 minutes per side until both sides are golden. Rest on a wire rack to drain any oil.

Step 07

Hold the buns over steaming water for a quick 10 seconds to soften them.

Step 08

Spread some sauce on the bottom bun, stack the fried fish, a cheese half, extra sauce, and then the top bun.

Notes

  1. Inspired by the classic Filet-O-Fish sandwich from McDonald's.
  2. Replace cod with haddock, halibut, or Alaskan pollock if preferred.
  3. Swap sparkling water with light beer for a twist in flavor.
  4. In a hurry? Use store-bought tartar sauce instead.
