• Paprika – Adds a mild spice and color to the dredge.

For the Sandwich
• Hamburger Buns – The base for the sandwich; ensure they are soft and fresh.

Step‑by‑Step Instructions for Fried Cod Fish Sandwich
Step 1: Heat Oil
Begin by pouring enough peanut oil into a deep skillet or frying pan to submerge the fish, about 2 inches deep. Heat the oil over medium-high heat until it reaches 375°F (190°C). Use a cooking thermometer to monitor the temperature closely; a properly heated oil ensures a crispy exterior on your Fried Cod Fish Sandwich.
Step 2: Make Tartar Sauce
While the oil is heating, prepare your homemade tartar sauce. In a medium mixing bowl, combine mayonnaise, Dijon mustard, lemon juice, diced dill pickles, capers, and chopped fresh parsley. Stir well until all ingredients are blended and creamy. Season with salt and pepper to taste, then set the sauce aside to let the flavors meld as you continue creating your sandwich.
Step 3: Prepare Fish
Take your fresh cod fillets and cut them into portions weighing around 4-6 oz each. Season each piece generously with salt and pepper to enhance the natural flavors of the fish. This step is crucial for ensuring that your Fried Cod Fish Sandwich is both flavorful and satisfying.
Step 4: Make Dry Dredge
In a shallow bowl, mix together all-purpose flour, Old Bay seasoning, paprika, turmeric, white pepper, and baking powder. This flavorful dry dredge will create the crispy coating on your fish. Ensure that all the spices are well combined, then set this mixture aside as you prepare for the wet dredge.
Step 5: Make Wet Dredge
In another bowl, whisk together one egg and sparkling water until smooth. Gradually mix in the seasoned dry dredge until you achieve a thick yet pourable batter. This wet dredge will add an additional layer of crunch to the coating of the fish, making your Fried Cod Fish Sandwich truly irresistible.
Step 6: Dredge Fish
Take your seasoned cod pieces and first coat them in the dry dredge mixture, ensuring an even layer. Next, dip them into the wet dredge, fully covering the fish. Allow any excess batter to drip off before frying. Proper dredging is key to achieving a perfectly crispy texture in your sandwiches.
Step 7: Fry Cod
Once the oil is hot, carefully place the dredged fish into the skillet, frying in batches to prevent overcrowding. Cook each piece for about 2-3 minutes on each side, or until they turn golden brown and crispy. Use a slotted spoon to transfer the fried cod to a wire rack to drain excess oil while you fry the remaining fish.
Step 8: Steam Buns
While the fish is cooling, briefly steam your hamburger buns to achieve a soft, pillowy texture. You can do this by placing the buns in a steamer basket over boiling water for just a minute or two. Steaming will mimic the classic fast-food softness that complements your crispy fried cod perfectly.
Step 9: Assemble Sandwich
To assemble your Fried Cod Fish Sandwich, spread a generous amount of the homemade tartar sauce on the bottom half of each steamed bun. Place a piece of crispy fried cod on top, followed by a half slice of cheddar cheese, and drizzle more tartar sauce over the fish. Finally, top it with the other half of the bun for a delightful finish to your sandwich!

Make Ahead Options
These Fried Cod Fish Sandwiches are perfect for busy cooks looking to save time without compromising on flavor! You can prepare the homemade tartar sauce up to 3 days in advance; simply combine all the ingredients and store it in an airtight container in the fridge. The fish can be seasoned and dredged up to 24 hours ahead; keep the coated pieces in the refrigerator, covered with plastic wrap, to maintain their crispiness. When you’re ready to serve, fry the cod for about 2-3 minutes on each side until golden and hot. With these make-ahead options, you’ll enjoy restaurant-quality sandwiches with minimal last-minute effort!

Fried Cod Fish Sandwich Recipe FAQs
What type of cod is best for this sandwich?
I recommend using fresh, flaky cod for the best results in your Fried Cod Fish Sandwich. If cod isn’t available, you can substitute it with Alaskan pollack, haddock, or halibut. Look for fillets that are firm and moist, with no dark spots or off-putting fishy odor.
How should I store leftovers?
To keep any leftover fried cod fish fresh, store it in an airtight container in the fridge for up to 2 days. For reheating, I suggest placing it in a preheated oven at 375°F (190°C) for about 10 minutes to help restore its crispy texture.
Can I freeze the fried cod fish?
Absolutely! You can freeze the fried cod fish for longer storage. First, let it cool completely, then place it in zip-top bags in a single layer. It can be stored in the freezer for up to 3 months. When you're ready to enjoy it again, thaw it overnight in the fridge before reheating to keep the crunch intact.
What if my fish isn’t crispy after frying?
If your fish doesn’t turn out crispy, it could be due to a couple of factors. First, ensure the oil is at 375°F when frying; too cool oil can make the coating soggy. Also, be sure to dredge the fish thoroughly in both dry and wet mixtures for that extra crunch. Another tip is to avoid overcrowding the pan, which can lower the oil temperature.
Is this sandwich suitable for kids or people with dietary restrictions?
This Fried Cod Fish Sandwich can be quite kid-friendly, as it's crispy and flavorful. For dietary restrictions, consider using gluten-free flour and buns to accommodate gluten sensitivities. Always check for any potential allergies related to specific ingredients, such as egg in the batter or seafood for those who have shellfish allergies.
