Beer-Battered Fish and Chips
Beer-battered fish and chips is the classic comfort meal: crackling golden batter around flaky white fish, with thick chips that are crisp outside and fluffy inside. Done right at home it beats most takeaways.

The secrets are a very cold batter, hot oil held at the right temperatures and frying the chips twice. It takes about an hour, and nearly all of it is easy.
The science: why this works
- Soaking the cut potatoes removes surface starch so the chips crisp instead of turning gummy.
- Frying chips twice, first gently and then hot, cooks the inside through before the outside crisps.
- A dusting of flour gives the wet batter something to grip so it does not slide off the fish.
- Cold beer and baking powder create bubbles in the batter, which makes a light and crackly coating.
- Draining on a rack, not paper towels, stops the underside steaming and going soft.
Why cold batter is crisper
Cold batter slows gluten from forming and keeps the flour mix from turning heavy. When it hits hot oil, water turns to steam quickly and leaves a network of tiny air pockets. The result is a thin, shattering crust, not a doughy shell.

The first fry at a low temperature gelatinizes the starch inside the potato until it is fluffy. The second fry at high heat dries the outside and starts browning. Skipping either stage gives chips that are either raw in the middle or limp.

The crust acts like a lid, trapping moisture so the fish steams gently inside while the outside fries. That is why the fish stays juicy at 145°F (63°C) even though the oil is far hotter than that.

Ingredients
Makes 4 servings
- 700 gcod or haddock fillets, cut into 4 pieces
- 1.2 kgrusset potatoes, cut into thick chips
- 360 mlall-purpose flour, plus 1/2 cup for dusting
- 1 tspbaking powder
- 1 tspkosher salt, plus extra for finishing
- ½ tspblack pepper
- 1 tsppaprika
- 300 mlcold light beer or sparkling water
- 1½ lvegetable or peanut oil for frying
- 1lemon, cut into wedges
- 120 mltartar sauce, to serve
- 1 tbspmalt vinegar, to serve
Method
Tips for the best result
- Use a thermometer and hold the oil near 375°F (190°C), adding fish only after it recovers.
- Keep the batter bowl over a larger bowl of ice to stay cold while you fry.
- Salt the chips the moment they leave the oil so the salt sticks.
Mistakes to avoid
- Putting wet fish in the batter makes the coating slide off, so dry it and dust it with flour first.
- Frying at too low a temperature makes greasy fish, so wait for the oil to climb back to 375°F (190°C) between batches.
- Overmixing the batter builds gluten and makes it chewy, so stir only until just combined.
Variations and swaps
- Swap the beer for sparkling water for an alcohol-free batter.
- Add a spoon of Old Bay or garlic powder to the batter for more flavor.
- Serve with mushy peas and curry sauce for a British chip shop style plate.
- Swap cod for haddock, pollock or tilapia, which all have a mild flavor.
- Swap the potatoes for sweet potatoes, fried once for 5 minutes at 375°F (190°C).
- Swap the all-purpose flour for a gluten-free flour blend and cornstarch.
Storing and reheating
Fish and chips are best eaten right away. Leftovers keep in the fridge for up to 3 days; reheat on a rack in a 400°F (200°C) oven or an air fryer until hot through to 165°F (74°C) and crisp.
Beer-Battered Fish and Chips: questions
What is the best fish for fish and chips?
Cod and haddock are the traditional choices because they are mild and flake into large, tender pieces. Pollock and tilapia also work well. Choose thick fillets of about 2 cm so they stay juicy.
What temperature do you fry fish and chips?
Fry the fish at 375°F (190°C), and fry the chips first at 300°F (150°C) and then again at 375°F (190°C). A thermometer helps you keep the oil steady, which matters for a crisp, not greasy, result.
Why does my batter fall off the fish?
The fish was probably wet, or the batter was too thin. Pat the fish very dry and dust it in flour before dipping so the batter has something to hold onto.
Can I use beer that is not light?
Yes, but a light lager or pilsner gives the cleanest flavor. Dark or hoppy beers can make the batter taste bitter. Sparkling water also works if you want no alcohol.
Can I make fish and chips in the oven or air fryer?
You can bake or air fry breaded fish, but a wet beer batter will not set and will drip. For an oven version use a flour, egg and panko coating instead.
