Ingredients You'll Need

On a dark baking tray lined with white parchment paper, there are two large raw white fish fillets placed side by side in the center. Above the fillets, there are five small clear glass bowls arranged in a row. From left to right, the first bowl contains a white powdery substance, the second holds a mix of reddish-brown spices, the third has black pepper and white salt, the fourth contains a white powder, and the fifth bowl holds a slightly chunkier white ingredient. The background is a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

The ingredient list for this recipe is delightfully simple but thoughtfully balanced. Each component plays a key role in giving you the perfect texture, crispiness, and flavor that stand out.

Vegetable oil (8 cups): Essential for deep frying to get that golden, crispy crust.
Flour (2 cups): The base of the batter, giving it structure and a light chew.

Cornstarch (¼ cup): Adds extra crispness to the fried coating.
Sugar (2 teaspoons): Balances the savoriness with a subtle hint of sweetness.
Salt (2 teaspoons): Enhances the natural flavors throughout.
Baking powder (½ teaspoon): Provides lift and airiness in the batter.

Baking soda (½ teaspoon): Works with acid to help the batter rise and brown beautifully.
Onion salt (½ teaspoon): Brings a gentle savory bite that complements the fish.
Paprika (½ teaspoon): Adds a smoky undertone and lovely color.

Ground black pepper (¼ teaspoon): Adds just a hint of warmth and spice.
Club soda (16 ounces): The secret to that light, airy batter texture.
Cod or other white fish (2 pounds): The star ingredient; mild and flaky fish works best for tender results.

Directions

Step 1: Heat about 8 cups of vegetable oil in a deep fryer or heavy, deep pot until it reaches 350°F. Maintaining this temperature is key to getting the perfect fry.

Step 2: In a large mixing bowl, combine the flour, cornstarch, sugar, salt, baking powder, baking soda, onion salt, paprika, and ground black pepper. Stir well to make sure all the spices and leavening agents are evenly distributed.

Step 3: Slowly add the club soda to the dry ingredients while stirring gently. The batter will foam up—that’s exactly what you want for a crispy texture!

Step 4: Dip each piece of fish into the batter, making sure it’s fully coated. This batter holds onto the fish beautifully, coating it in a thick, bubbly layer.

Step 5: Carefully drop the battered fish pieces into the hot oil. Fry them for 2 to 3 minutes until the batter turns a golden brown and the fish begins to float to the surface.

Step 6: Remove the cooked fish from the oil and drain on a wire rack. This keeps the batter crisp without getting soggy.

Servings and Timing

This Long John Silver's Fish Batter Copycat Recipe makes about 6 servings, perfect for sharing with family or friends.

I love serving this crispy fish with classic sides like crispy fries or coleslaw for that true seaside meal feel. A simple tartar sauce or fresh lemon wedges elevate the flavors even more, cutting through the richness of the batter with a bright, zesty contrast. For presentation, placing the fish on a wire rack over a baking sheet helps keep the coating crisp instead of soggy when plated.

For a fun twist, I sometimes pair this fish with homemade hush puppies or a light garden salad to keep the meal balanced and refreshing. When it comes to drinks, a chilled lager or a crisp white wine like Sauvignon Blanc enhances the light, flaky fish beautifully. For non-alcoholic options, a sparkling lemonade or iced tea feels just right with this meal.

This dish is fantastic for casual family dinners, weekend get-togethers, or even casual parties where finger foods shine. I recommend serving the fish hot and crispy, straight from the fryer for the ultimate eating experience. Portion around 3-ounce fish pieces per person to satisfy without overwhelming, leaving room for sides and extras.

Variations

I’ve experimented with this Long John Silver's Fish Batter Copycat Recipe by swapping the fish for different types like haddock or even shrimp, which work wonderfully in the same batter. For a gluten-free version, I replace the flour and cornstarch with a gluten-free flour blend and use club soda as usual for the batter’s light texture. You’ll still get that signature crispiness.

If you want to add a flavor punch, mixing a pinch of cayenne pepper or Old Bay seasoning into the batter brings a smoky heat I adore. For those avoiding traditional frying, baking the batter-coated fish on a high rack with a light spray of oil is a healthier alternative, though it won’t quite match the same crunch but still tastes fantastic.

For a vegan take, swapping out fish for large cauliflower florets or even banana blossoms battered the same way creates a satisfying plant-based "fish" dish. The batter holds up just as well on these substitutions and delivers a delicious crunchy exterior with a tender inside.

Storage and Reheating

Storing Leftovers

If you have any leftovers, place them in an airtight container lined with paper towels to absorb moisture. The fish will keep well in the fridge for up to 2 days. I generally recommend eating them within this timeframe to maintain the best texture and flavor.

Freezing

This fried fish can be frozen, though the texture changes slightly. To freeze, first let the fish cool completely, then wrap pieces individually in plastic wrap or foil and place them in a freezer-safe bag. They will keep well for up to 1 month. When ready to eat, thaw overnight in the fridge before reheating.

Reheating

To reheat, I find the best method is using an oven or air fryer at 350°F for about 8-10 minutes. This helps restore the crispiness without drying out the fish. Avoid microwaving as it tends to make the batter soggy and soft. Keeping the fish on a wire rack in the oven ensures even reheating and a crunchy exterior.

FAQs

Can I use a different type of fish for this batter?

Absolutely! While cod is classic for this recipe, other white fish like haddock, pollock, or tilapia work beautifully. You just want a flaky, mild fish that won’t overpower the batter’s flavor.

Do I need to use club soda in the batter?

Yes, club soda is key to creating that light, crispy texture. The carbonation aerates the batter, making it wonderfully airy. If needed, you can substitute sparkling water, but plain water won’t give the same result.

Is it okay to reuse the frying oil?

You can reuse the oil if you strain it well after cooling to remove any crumbs. Store it in a sealed container in a cool, dark place for up to two uses. Always check that the oil hasn’t degraded or developed off-flavors before reusing.

Can I make the batter ahead of time?

I recommend mixing the dry ingredients ahead but adding the club soda right before frying. The batter starts to lose its fizz quickly, so for the best light texture, prepare it fresh for each batch.

What’s the best way to test if the oil is at the right temperature?

A candy or deep-fry thermometer is ideal for accuracy. Alternatively, you can drop a small bit of batter into the oil; if it bubbles up and floats to the surface quickly without burning, the oil is ready at about 350°F.
