Some fried fish gets a thick, doughy breading, but this recipe creates the kind of shell where you tap the crust with a fork and hear it crack. The cornstarch keeps the coating ultra-light and extra-crunchy, while the flour gives it structure. That satisfying first crack when you break a piece open is the whole reason to make it this way!
Whether you are aiming for pub-style fish and chips or a quick weekend seafood dinner, this simple copycat batter turns standard white fish fillets into a restaurant-quality meal.

Ingredients Summary Table
| Ingredient | Quantity | Purpose & Prep Notes |
| All-Purpose Flour | ¾ cup | Builds structure for the crispy coating. |

| Baking Soda & Powder | ¼ tsp each | Leavening agents that create airy bubbles in the shell. |
| Salt | ¼ tsp | Seasons the batter for savory depth. |
| Cold Water | ¾ cup | Binds ingredients; must be ice-cold for maximum crispness. |
| White Fish Fillets | 1 lb | Dried thoroughly with paper towels before dipping. |
Step-by-Step Instructions
1.Whisk Dry Ingredients:Combine dry ingredients in a medium bowl.In a medium mixing bowl, whisk together ¾ cup all-purpose flour, 2 tablespoons cornstarch, ¼ teaspoon baking soda, ¼ teaspoon baking powder, and ¼ teaspoon salt until evenly distributed.
2.Mix the Batter:Add cold water and stir briefly.Pour in ¾ cup cold water. Stir just until smooth and combined. Do not overmix, as keeping the batter cool and lightly mixed yields a delicate crust.
3.Prep Oil & Coat Fish:Heat oil to 350°F and coat dried fish fillets.Heat frying oil in a heavy-bottomed pot or deep fryer to 350°F. Pat the 1 lb white fish fillets completely dry with paper towels. Dip each fillet into the batter, allowing excess to drip off gently back into the bowl.
4.Fry to Perfection:Fry in hot oil until deeply golden and crispy.Carefully lower the battered fish into the hot 350°F oil. Fry for 4 to 6 minutes (depending on fillet thickness) until the crust is deeply golden, ultra-crispy, and the fish inside flakes easily with a fork.
5.Drain and Serve:Drain on a wire rack to maintain crunch.Transfer the fried fish to a wire cooling rack set over a rimmed baking sheet. Draining on a wire rack keeps the bottom from becoming soggy. Serve immediately while hot and crackly.
Expert Frying Tips for Success
- Use Ice-Cold Water: Using ice-cold water stops gluten from developing rapidly, keeping the fried coating light and flaky rather than heavy or doughy.
- Pat Fish Completely Dry: Moisture on the surface of raw fish causes batter to slide off during frying. Drying the fillets with paper towels ensures the coating adheres evenly.
- Always Drain on a Wire Rack: Laying fried fish on paper towels traps steam beneath it, softening the bottom crust. A elevated wire rack allows air to circulate so every angle stays crisp.
Variations & Serving Ideas
- Beer-Battered Upgrade: Replace the cold water with an equal amount of ice-cold carbonated beer (like a light lager or ale) for extra lift and flavor.
- Flavored Seasonings: Add ½ teaspoon of garlic powder, Old Bay seasoning, or paprika to the flour mixture for an added kick.
- Classic Platter Pairing: Serve alongside crispy French fries, creamy coleslaw, lemon wedges, and tart homemade tartar sauce.
Storage & Reheating Instructions
- Refrigerator: Store leftover fried fish in an airtight container in the fridge for up to 2 days.
- Reheating for Maximum Crispness: Reheat leftovers in an air fryer or regular oven preheated to 375°F (190°C) for 5 to 8 minutes until hot and crackly again. Avoid using the microwave, as it softens the crispy coating.
