Perfect Long John Silver’s Batter turns simple budget fish fillets into ultra-crispy golden bites right at home. After many attempts to recreate that signature crunch without the sogginess or heaviness I finally landed on this batter recipe and it brings back memories of road trips and fast food Fridays with my family.
The first time I nailed this batter my kitchen was filled with that irresistible fried smell and my kids tore through the platter before I sat down. It quickly became our go-to for fish and chip nights whether it was summer picnics or rainy winter dinners.
Ingredients
- All-purpose flour: brings structure choose a bleached flour for more tenderness
- Cornstarch: ensures a lighter crunch use pure cornstarch not blends labeled as starch
- Baking powder: creates bubbles for an airy crispness always check that your powder is active and fresh
- Salt: boosts flavor use fine sea salt for even seasoning
- Cold sparkling water: makes the batter extra light and puffy the colder the better direct from the fridge or freezer
- Optional but authentic: a dash of paprika and garlic powder for subtle flavor and color pick paprika with vibrant color and aroma
- Neutral oil for frying: such as peanut or canola with a high smoke point look for fresh oil without any off smells
Step-by-Step Instructions
- Mix the Dry Ingredients:
- In a large mixing bowl add the flour cornstarch baking powder salt and any spices like paprika or garlic powder if using. Stir thoroughly with a whisk so the leavener and spices are perfectly distributed. This prevents uneven flavor or big baking powder pockets which can make the fried crust taste metallic.
- Prep the Wet Ingredients:
- Measure out your ice-cold sparkling water. If you want to add an extra flavor layer use a mix of half cold beer and half sparkling water. The bubbles in these liquids make the batter light and crunchy when hitting hot oil.
- Make the Batter:
- Slowly pour the sparkling water into the dry mixture whisking gently just until no big dry spots remain. The batter should be the consistency of heavy cream and a little lumpy is good. Overmixing will make the crust tough. The key is to stop as soon as you see the lumps break up.
- Rest the Batter:
- Let the batter sit in the fridge for at least ten minutes while you prep your seafood. This lets the flour hydrate and the bubbles set so you get the lightest result.
- Prepare the Seafood:
- Pat your fish fillets thoroughly dry with paper towels and slice into portions if needed. Moisture will keep the batter from sticking and ruin that crisp finish.
- Heat the Oil:
- Pour at least two inches of oil into a deep heavy pan. Heat to between three hundred fifty and three hundred seventy five degrees Fahrenheit using a thermometer for precision. This stage sets the crisp shell in seconds.
- Coat and Fry:
- Dip each piece of dried seafood in the batter letting the excess drip off. Carefully lower into the hot oil. Fry just a few pieces at a time so the temperature stays high. Cook three to five minutes per side turning once until each piece is golden brown and crisp.
- Drain and Serve:
- Lift the fried seafood onto a wire rack set over a tray not directly on paper towels which can trap steam and cause sogginess. Let cool briefly then serve hot with your favorite dipping sauces.

My personal favorite part is the moment each battered fillet puffs and crisps up in the hot oil releasing that aroma of nostalgia. Every time I use this recipe I remember my dad letting me sneak a corner of crunchy coating before dinner and it’s still my favorite bite.
Storage Tips
Store any leftover dry batter mix in a sealed jar in a cool pantry for up to three months just add cold liquid when you are ready. Once mixed with liquid keep batter refrigerated and use within twenty four hours for best crunch. Fried pieces reheat best in a toaster oven or hot air fryer to recapture that crispness.
Ingredient Swaps
You can swap all-purpose flour for an equal amount of rice flour for a gluten-free version but the texture will be extra light and delicate. No cornstarch Use potato starch or tapioca starch for a similar result. To make it dairy free just use sparkling water or plain seltzer.

Serving Suggestions
Pair the crispy seafood with fresh lemon wedges tartar sauce or a simple cabbage slaw. For a traditional touch serve with chips or fries. Kids also love these in soft white sandwich buns for homemade fish sandwiches.
