Ingredients You’ll Need

To nail this Copycat Filet-O-Fish Sandwich Recipe, you don’t need a fridge full of fancy ingredients. What you do need are some simple, quality basics that come together to bring flavor, crunch, and that iconic look to your sandwich.

• Pollock filets: Skinless and boneless, around 4 ounces each, these are the perfect mild-flavored fish for a flaky texture.
• All-purpose flour: The base for your batter, providing structure and that crisp coating after frying.
• Cornflour: Adds extra crispiness to the fried fish, different from cornmeal which is grainier.
• Cornstarch: Helps the batter stay light and crunchy by absorbing moisture.
• Turmeric and paprika: Just a pinch for color to give the fish that golden, appetizing hue.
• Breadcrumbs: A light coating to add a subtle crunch without overpowering the batter.
• Mayonnaise: The creamy base for the tartar sauce that ties the sandwich together.
• Pickles, yellow onion, and capers: Chopped finely, they deliver the tang and texture that make the tartar sauce sing.
• White vinegar and sugar: Balance the tart and sweet notes in the sauce, enhancing overall flavor.
• American cheese slices: The melty, slightly salty layer that completes the sandwich experience.
• Burger buns: Ideally brioche, soft but sturdy enough to hold all that goodness without falling apart.
• Oil for frying: Use a neutral oil with a high smoke point to get that perfect golden crust.
• Salt: Essential seasoning throughout, enhancing every component beautifully.

How to Make Copycat Filet-O-Fish Sandwich Recipe

Step 1: Prepare the Fish

Start by patting the pollock filets dry with paper towels. This step is golden because it ensures the batter sticks better and the fish fries up crispy instead of soggy. Run your finger down the center of each filet to check and remove any pin bones — no one wants to bite into a little surprise. Lightly season both sides of the fish with salt for that subtle flavor lift. To make folding easier and ensure even frying, fold the ends of the fish over in thirds and make a shallow cut along each fold without cutting through. If this sounds tricky, you can alternatively cut the filets to your preferred size and move on.

Step 2: Make the Tartar Sauce

In a bowl, combine mayonnaise, finely chopped pickles, diced yellow onion, minced capers, white vinegar, sugar, and a generous pinch of salt. Mix everything until it’s well combined, creamy, and bursting with tangy, sharp notes. Pop it in the fridge to chill — this sauce works its magic when all the flavors have a chance to mingle.

Step 3: Prepare the Fry Batter

Whisk together all-purpose flour, cornflour, cornstarch, salt, and a pinch each of turmeric and paprika for that lovely golden color. Slowly add water while whisking until you have a smooth, pourable batter. Let it rest briefly; it thickens slightly and sticks beautifully to the fish.

Step 4: Fry the Fish

Heat your oil to around 350°F (175°C), prepping a rack or paper towels for draining the cooked fish. Pat the folded fish filets dry again with paper towels—moisture on the surface will fight the batter’s crispiness. One by one, dip the fish into the batter, letting any excess drip off, then lightly coat with breadcrumbs, no pressing needed. Carefully lower the filets into the hot oil and cook for 3 to 5 minutes, flipping occasionally, until they turn golden brown and the fish flakes easily. When the sizzling intensifies, that’s your cue that the fish is cooked through.

Step 5: Steam the Buns (Optional)

If you want that authentic soft, pillowy bun experience, steam your buns for 10 to 15 seconds before assembling. Just add water to your steamer, bring it to a boil, and steam the buns, crumb side down. This step adds that light softness that melts in your mouth.

Step 6: Assemble and Enjoy!

Place a fried fish filet on the bottom half of each steamed bun, top it with a slice of American cheese, and add a generous spoonful of your homemade tartar sauce. Cap it with the top bun, and there you have it: your very own Copycat Filet-O-Fish Sandwich, ready to devour while it’s all warm and melty.

How to Serve Copycat Filet-O-Fish Sandwich Recipe

Garnishes

While the sandwich shines on its own, adding a few fresh touches can take it over the top. A crisp lettuce leaf or a thin slice of tomato provides a refreshing crunch and a pop of color that contrasts beautifully with the rich fish and sauce. A dash of freshly ground black pepper or a squeeze of lemon on the fish elevates the brightness if you want to add a little zing.

Side Dishes

Classic sides like golden fries or crispy onion rings complement the sandwich perfectly, creating that authentic fast-food vibe at home. For a lighter touch, consider serving with a tangy coleslaw or a simple green salad dressed with vinaigrette. Pickled vegetables also make a delightful companion, echoing the tartness in the sauce.

Creative Ways to Present

Feeling adventurous? Try serving your Copycat Filet-O-Fish Sandwich over a bed of fresh greens for an open-faced fish salad twist. You can swap out the typical bun for a toasted English muffin or a soft slider bun for a fun variation. Wrapping the sandwich in parchment paper with a little toothpick or skewer not only looks charming but makes it perfect for picnics or casual gatherings.

Make Ahead and Storage

Storing Leftovers

If you have any leftover fish or components, store the fried filets and tartar sauce separately in airtight containers in the fridge. The fish will keep well for up to 2 days, though it’s best enjoyed fresh for maximum crispness.

Freezing

For longer storage, you can freeze the raw, prepared fish prior to frying by wrapping each filet tightly in plastic wrap and placing them in a freezer bag. The cooked filets don’t freeze as well because they tend to lose crispness, but you can freeze the tartar sauce ingredients separately if needed.

Reheating

Reheat fried fish gently in an oven or air fryer at 350°F (175°C) for about 5 to 8 minutes to restore crispness without drying out. Avoid microwaving if you can, as it can make the batter soggy. The tartar sauce is always best served cold, so keep it refrigerated until ready to use.

FAQs

Can I use a different type of fish?

Absolutely! Pollock is great for its mild flavor and flaky texture, but cod, haddock, or tilapia can work wonderfully as alternatives in this Copycat Filet-O-Fish Sandwich Recipe.

Is it necessary to steam the buns?

Steaming the buns is optional but highly recommended for that soft, fluffy texture similar to the original sandwich. If you don’t have a steamer, warming them slightly in a microwave wrapped in a damp paper towel is a quick fix.

How do I make the batter extra crispy?

Using a combination of flour, cornflour, and cornstarch helps create that irresistible crispiness. Also, keep your oil temperature steady at 350°F and avoid overcrowding the pan when frying to maintain the crunch.

Can I make the tartar sauce ahead of time?

Definitely! The tartar sauce actually tastes better when it’s had time to chill and let the flavors meld. Prepare it up to a day ahead and keep it refrigerated until use.

What type of cheese works best?

American cheese slices are traditional for this sandwich due to their excellent meltability and mild flavor, perfectly complementing the fish without overpowering it.
