The crisp sandwich, made with soft white bread, Kerrygold butter, and salty cheese-and-onion crisps, has been a staple of Irish kitchens for generations.

It recently gained international attention after actors Colin Farrell and Margot Robbie revealed they shared the sandwich daily while filming together, with Robbie reportedly calling it “heaven.”

Part of its charm lies in its simplicity.

Most devotees agree on the essentials: two slices of soft white bread generously spread with softened Kerrygold – the world-famous Irish grass-fed butter – and layered with cheese-and-onion potato crisps.

Close the sandwich, give it a gentle press so the layers meld together, and it’s ready to eat.

Despite its humble ingredients, the crisp sandwich has travelled far beyond Irish kitchens.

In 2015, Ireland’s national airline, Aer Lingus, even offered DIY crisp sandwich kits on flights – complete with bread, Tayto crisps, and a pat of Kerrygold butter so passengers could assemble the classic mid-air.

“The crisp sandwich proves that the simplest ingredients often create the most memorable food traditions,” says Senior Global Brand Manager Neil Rogers.

“It’s nostalgic, comforting, and unmistakably Irish – which makes it the perfect snack.”
