Jamie Oliver Fish and Chips Recipe: Crispy Batter and Flaky Cod

This classic dish delivers crispy batter and flaky cod every time, just like your favorite British pub. The secret lies in the double-frying technique for the chips and ice-cold beer batter for the fish.

I’ve tested this method countless times to achieve that perfect golden crust without sogginess. The cod stays moist inside while the batter turns light and airy, shattering at the slightest touch.

Serve with thick-cut chips that are soft on the inside and crispy on the outside. A squeeze of lemon and a side of mushy peas complete the experience.

This recipe brings restaurant-quality results to your kitchen with simple, foolproof steps. The key is patience and precision.

Ingredients for Jamie Oliver Fish and Chips

Classic British pub staples for crispy, flaky perfection at home.

The cod needs to be fresh or previously frozen—thaw completely if using frozen. Wild-caught Pacific cod is my go-to, but any firm white fish works. For the beer, pick a light lager (Budweiser or Heineken) and make sure it’s ice-cold. This creates the lightest, airiest batter. Most supermarkets carry good cod fillets, but Whole Foods has great sustainable options if you want to splurge.

No beer? Sparkling water or club soda works in a pinch—just add a pinch of salt to mimic the flavor. Out of cod? Haddock or pollock are solid substitutes. For the chips, Yukon Golds work if you can’t find Russets. Skip the cornstarch? The batter will still be good, just a tad less crispy. The malt vinegar is traditional, but white vinegar gets you 90% there.

Double-fried chips stay crispy for 10 minutes out of the oil. The fish? Best eaten immediately—it loses crispness fast. Leftovers? Reheat fish in a 400°F oven for 8-10 minutes to revive. The mushy peas keep 3-4 days in the fridge, but honestly, they’re best fresh.

Step-by-Step Instructions for Crispy Fish and Chips

Here’s how I get that perfect golden crust and tender flakes every single time.

Step 1: Prep the Potatoes and Start Frying

Peel the 3 whole Russet Potatoes and cut them into thick sticks—about ½-inch wide. Rinse under cold water to remove excess starch, then pat completely dry. This step prevents soggy fries later.

Heat the 4 cups Vegetable Oil in a deep pot to 325°F. Fry the potatoes in batches for 4-5 minutes until soft but not browned. Remove with a slotted spoon and drain on paper towels. This first fry cooks them through without over-browning.

Step 2: Make the Light, Crispy Batter

In a large bowl, whisk together the 2 cups All-Purpose Flour, 2 tsp Baking Powder, 1 tsp Salt, and 0.5 cup Cornstarch. The cornstarch is the secret to extra crispiness.

Slowly pour in the 1.5 cups Cold Lager Beer while whisking until smooth. The batter should be thick enough to coat the back of a spoon but still pourable. Let it rest for 5 minutes while you prep the cod.

Step 3: Fry the Cod to Golden Perfection

Pat the 1.5 lb Cod Fillets dry with paper towels—this ensures the batter sticks properly. Increase the oil temperature to 375°F. Dip each piece of cod into the batter, letting excess drip off, then carefully lower into the hot oil.

Fry for 4-5 minutes per side until the batter is deep golden brown and the fish is cooked through. The cod should flake easily with a fork. Drain on a wire rack set over a baking sheet to keep it crispy.

Step 4: Finish the Fries and Make the Mushy Peas

Increase the oil temperature back to 375°F and fry the potatoes again for 2-3 minutes until golden and crispy. This second fry gives them that classic fish-and-chips texture.

Meanwhile, cook the 2 cups Frozen Peas in boiling water for 2 minutes. Drain, then mash with the 2 tbsp Butter, 0.25 cup Malt Vinegar, and a pinch of 0.5 tsp Black Pepper. The vinegar adds that traditional tangy kick.

Step 5: Serve with Fresh Garnishes

Plate the crispy cod and fries immediately. Sprinkle with chopped 0.25 cup Fresh Parsley for a pop of color. Serve with the mushy peas on the side and wedges of 1 whole Lemon for squeezing over the fish.

This is best eaten right away while everything is hot and crispy. The contrast of the flaky cod, crunchy batter, and soft fries with the tangy peas is what makes this dish so satisfying.

Pro Cooking Tips for This Recipe

Double-Fry for Chips

Start with 325°F oil for the first fry to cook potatoes through without browning. Then increase to 375°F for the second fry to achieve that perfect golden, crispy exterior. I use a deep-fry thermometer for precision. 🌡️

Ice-Cold Beer Batter

The beer must be ice-cold to create a light, airy batter. Whisk 1.5 cups with dry ingredients until just combined—overmixing makes it tough. Rest the batter for 5 minutes before using.

Dry the Cod Well

Pat the 1.5 lb cod fillets completely dry with paper towels. Any moisture prevents the batter from adhering properly. I also dust them lightly with extra flour for extra crispiness.

Oil Temperature Control

Maintain consistent oil temps: 375°F for frying the fish. If it drops too low, the batter absorbs oil and becomes greasy. Use a kitchen thermometer to monitor closely.

A heavy-bottomed pot helps regulate heat. I recommend Le Creuset for even distribution.

Drain on a Rack

Never drain fried foods on paper towels alone. Use a wire rack set over a baking sheet to allow airflow on all sides. This keeps the batter crispy and prevents sogginess. 💡
