This upgraded Fish Sandwich turns fresh cod into a golden, crunchy delight that beats any restaurant option. The mix of well-seasoned fish, homemade tartar sauce, and soft brioche buns brings together old-school comfort and fancy cooking in every bite.

I've tweaked this in my kitchen for years and found that double-dipping the fish and watching the oil temp are game-changers. These days my family begs for these instead of getting takeout.

Prime Ingredient Breakdown

  • Cod fillets: Go for chunky, solid pieces for the best sandwich
  • Peanut oil: Won't burn when you're frying at high heat
  • Old Bay Seasoning: Gives that perfect ocean-y taste
  • Sparkling water: The secret to an airy, crispy coating
  • Fresh parsley: Brightens up your homemade sauce
  • Dill pickles: Brings the right amount of zing to your sauce
  • Brioche buns: Adds a buttery softness against the crunchy fish

Foolproof Cooking Instructions

Whipping Up Tartar Sauce:
Chop pickles and capers really small. Stir mayo until it's smooth. Throw in everything bit by bit. Add salt and pepper how you like. Let it sit while you cook the fish.
Getting Your Oil Right:
Warm oil gradually so it doesn't get too hot. Keep it steady at 375°F. Use a deep, heavy pot. Stick the thermometer on the side. Turn heat up or down as you go.
Getting Fish Ready:
Slice fish into equal chunks. Dry them completely with paper towels. Add plenty of seasoning. Keep them out at room temp. Set up your flour and batter stations.
Coating Your Fish:
Roll in seasoned flour first. Tap off extra flour. Dunk fully in batter. Let extra batter drip away. Go straight to the hot oil.
Frying It Up:
Ease fish into oil carefully. Don't put too many pieces in at once. Flip just one time while cooking. Watch the color and bubbling. Put on wire rack after frying.

This all started when I tried to copy my grandpa's famous fish fry, but I think it's grown into something he'd enjoy even more than his original.

Oil Temperature Tricks

After tons of trial runs, I've learned that keeping the oil at the right heat is super important. I clip a candy thermometer to my pot and adjust my stove as needed. When oil gets too hot, the outside burns before the fish cooks inside. Too cool and your fish soaks up oil like a sponge.

Prep-Ahead Strategies

The fish tastes best when fried right before eating, but I often get other stuff ready ahead of time. The tartar sauce actually gets better overnight as flavors blend together. I also mix my dry coating ingredients and store them separately so I can throw everything together quickly when I'm hungry.

Picking Perfect Buns

Don't overlook how important the right bun is. After trying pretty much everything, brioche buns win hands down for their mix of sturdiness and softness. Giving them a quick steam adds moisture but keeps them fluffy.

Switching Up Your Sauce

I've played around with lots of extras in my tartar sauce over time. Adding finely chopped shallots gives it extra punch, while fresh dill makes it more herby. If you like things spicy, a little cayenne or finely diced jalapeños works wonders.

What To Serve With It

These sandwiches go great with classic sides. I usually make some crunchy coleslaw, fresh-cut fries, or a tangy citrus salad. When friends come over, I set out different sauces and veggies so everyone can build their perfect sandwich.

Using Up Extras

Though they're best fresh, you can reheat leftover fish in a 350°F oven until it crisps up again. I always keep the sauce in a separate container and make extra because it tastes amazing on other sandwiches too.

These Fish Sandwiches have become the dish everyone asks me to make, from casual Tuesday dinners to weekend get-togethers.

Every time I make them, I'm reminded that sometimes the simplest foods, made with love and attention to small details, become the meals we cherish most.

Frequently Asked Questions

→ How do I get the fish super crunchy?
Double-coat it first in flour, then in batter, and keep the oil at a steady 375°F while frying. That'll give the perfect texture!
→ Can tartar sauce be prepped early?
Absolutely! Make it up to three days ahead and store it in the fridge. Letting it sit makes the flavors blend better.
→ What does sparkling water do in batter?
It makes the coating airy and light. A fizzy light beer works just as well if you prefer that.
→ Can frozen fish be used?
Sure, but make sure it's thawed completely and dried well. That way, it fries up as crispy as fresh fish.
→ Why is steaming buns important?
It keeps the buns soft and fluffy, helps the cheese melt, and gives them that restaurant-like charm.
