Crispy Beer Fish Batter
This is the light, lacy coating behind proper British chip-shop fish: a thin beer batter that fries up shatteringly crisp and deep golden while the fish steams tender inside. The lager does double duty, its bubbles and low protein keeping the crust airy rather than bready, while a hit of cornflour and baking powder guarantees crunch. Mixing it ice-cold and frying straight away is the whole trick — the shock of cold batter hitting hot oil is what makes it crackle.
Pat 4 skinless white fish fillets bone-dry, season, and dust lightly with flour so the batter grips. Heat 1.5 litres of neutral oil to 180°C/356°F in a deep, heavy pot. Whisk 200 g plain flour, 60 g cornflour, 1½ tsp baking powder and 1 tsp salt, then pour in 330 ml of ice-cold lager and stir just until it comes together — a few lumps are fine and mean a lighter crust. Working one at a time, drag each floured fillet through the batter, let the excess drip off, then lower it away from you into the oil. Fry two pieces at a time for 6–8 minutes, turning once, until deep golden and crisp; drain on a wire rack, season with flaky salt, and serve straight away.
- Keep the batter ice-cold and the oil steady at 180°C/356°F — that temperature gap is what makes the crust shatteringly crisp.
- Dust the fish with flour before dipping so the wet batter clings instead of sliding off in the oil.
- Fry in small batches and rest the fish on a wire rack, never on paper on a plate, so the crust stays crisp instead of steaming soft.

Ingrediënten
Beer batter
- 200 g Plain (all-purpose) flour
- 60 g Cornflour (cornstarch), for extra crispness
- 6 g Baking powder
- 5 g Fine sea salt
- 330 ml Cold lager or pale ale, ice-cold, about one bottle
Fish & frying
- Skinless white fish fillets, cod, haddock or pollock, about 150 g/5 oz each, patted very dry
- 40 g Plain (all-purpose) flour, for dusting
- 1.5 L Neutral oil for deep-frying, sunflower, rapeseed or vegetable
- Flaky sea salt, for finishing
Bereiding
- STAP01
Pat the fish fillets completely dry with paper towels — surface moisture is the enemy of crisp batter. Season lightly with salt, then dredge each fillet in the dusting flour, tapping off the excess. Set aside on a plate while the oil heats.
- STAP02
Pour the oil into a deep, heavy pot no more than two-thirds full and clip on a thermometer. Heat to 180°C/356°F. Set a wire rack over a tray nearby for draining, and heat your oven to a low 120°C/250°F to keep batches warm.
- STAP03
In a large bowl, whisk together the plain flour, cornflour, baking powder and 1 tsp fine salt until evenly combined. Do this while the oil comes up to temperature so the batter can be mixed at the last second.
- STAP04
Pour in the ice-cold lager and stir with a fork or whisk just until you have a batter the consistency of pouring cream. Stop while a few small lumps remain — overmixing builds gluten and makes the crust heavy and chewy.
- STAP05
Working with one fillet at a time, drop it into the batter and turn to coat fully, then lift it out and let the excess run back into the bowl for a couple of seconds so the coating is thin and even.
- STAP06
Lower two coated fillets away from you into the oil, one at a time, and fry for 6–8 minutes, turning once, until deep golden and crisp and the fish is opaque and flaking. Keep the oil between 170–180°C/338–356°F, adjusting the heat as needed.
- STAP07
Lift the fish onto the wire rack and season immediately with flaky salt, then hold in the warm oven. Let the oil return to 180°C/356°F and fry the remaining fillets the same way.
- STAP08
Serve the fish the moment it is all cooked, while the batter is at its crispest, with your chosen sides and a wedge of lemon.
Make ahead
You can dust the fish in flour and mix the dry batter ingredients a few hours ahead, but only add the cold beer and fry right before serving — the fizz and chill of a freshly mixed batter are what give the crispest result.
Storage
Battered fish is best eaten immediately. Leftovers keep in an airtight container in the fridge for up to 2 days; reheat in a 200°C/400°F oven or air fryer for 8–10 minutes to re-crisp the coating. Avoid the microwave, which turns the batter soggy.
Variations
Gluten-free beer batter
Swap the plain flour for a gluten-free blend, keep the cornflour, and use a gluten-free beer or hard cider. The extra cornflour makes this version especially light and crunchy.
Alcohol-free sparkling batter
Replace the beer with ice-cold sparkling water or soda water for the same airy bubbles without the alcohol — ideal if you're cooking for kids or skipping the beer.
Spiced pub batter
Whisk ½ tsp smoked paprika, ¼ tsp cayenne and a pinch of white pepper into the dry mix for a warm, seasoned crust that leans towards a spiced fish-and-chip-shop style.

Veelgestelde vragen
Why use beer in fish batter?
Beer brings three things to a fish batter that water can't: carbon dioxide bubbles that puff the coating, alcohol that evaporates fast for a drier, crisper crust, and a little sugar and protein that boost browning. A cold, light lager gives the cleanest crunch.
What's the best fish for beer-battered fish?
Firm, flaky white fish holds up best. Cod and haddock are the classics, but pollock, hake or whiting all work well. Choose skinless fillets of even thickness, around 150 g each, so they cook through in the time it takes the batter to turn golden.
Why isn't my fish batter crispy?
The usual culprits are warm batter, oil that's too cool, or crowding the pan. Mix the fish batter with ice-cold beer at the last minute, keep the oil at 180°C/356°F, fry only two pieces at a time, and rest the fish on a wire rack rather than paper towels so steam can escape.
Can I make fish batter without beer?
Yes — cold sparkling water or soda water is the best substitute, giving you the same lift from the bubbles without any alcohol. The flavour is a touch more neutral, so season the batter well and finish the fish with flaky salt.
Do I need to let the batter rest?
No. Unlike a yeasted or thick batter, this one is best used straight away while the beer is still fizzing and cold. Resting flattens the bubbles and lets gluten develop, which gives a denser, less crackly crust.
