The agency won the business after a competitive pitch, which kicked off in November last year and was overseen by Neil McIntosh, the head of marketing at Le Creuset UK.
Krow will be responsible for Le Creuset's first international advertising campaign, which will run across the UK, Germany and Scandinavia. Ignite was the incumbent on the UK account.
Le Creuset built a strong advertising reputation in the 90s and the early part of the last decade when TBWA\London was the incumbent.
In 2001, the agency's "adventure equipment" campaign achieved six entries in the D&AD Annual.
McIntosh said: "Krow stood out from the start as an agency that not only had great creative talent but was passionate about cooking. We're confident it will deliver a strong idea that will reinforce our vision for the brand."
