The all dressed potato chip flavor is poised for a significant breakthrough in the United States. This flavor, a bestseller in Canada, combines elements of barbecue, sour cream and onion, salt and vinegar, and ketchup. For years, it remained largely unknown outside Canada, but recent test runs have set the stage for its potential expansion into the U.S. market.

Originating in Quebec, the term "all dressed" translates to "everything on it." The concept predates potato chips, with advertisements for all dressed pizza appearing in newspapers long before chips were mentioned. The first known print ad for all dressed chips dates back to 1986, from the Quebec-based Yum Yum Chips. The company claims to have created a secret all dressed recipe in 1978, although major brands like Ruffles and Old Dutch did not introduce their versions until the 1990s.

Janis Thiessen, a historian specializing in Canadian snack food, noted that Canadian chip flavors tend to be more vinegar-based, while American flavors often lean towards dairy. This difference may stem from varying immigration patterns in the early 1900s, which influenced regional taste preferences.

PepsiCo, which owns Lay’s, Ruffles, and other snack brands, began experimenting with all dressed chips in the U.S. about a decade ago. The flavor ranks among the top five for PepsiCo in Canada. Ryan Collis, president of PepsiCo Foods Canada, described Ruffles All Dressed as a "Canadian icon." As demand grew in northern U.S. states, PepsiCo faced requests from American consumers to bring the flavor to their stores.

In 2015, PepsiCo attempted to introduce all dressed chips under the Ruffles brand. The initial trial was successful enough to keep the flavor available until 2021. However, a kettle-cooked version was short-lived. Last year, PepsiCo decided to give all dressed its most extensive trial yet by launching it under the Lay’s brand.

To adapt the flavor for American consumers, PepsiCo's flavor team conducted extensive testing and modifications. Justin French, who leads the flavor team, explained that the seasoning must be adjusted for different chip bases. The new formula for Lay’s all dressed chips features less tanginess and more barbecue notes compared to the original.

To enhance recognition in the U.S., Lay’s introduced a new tagline: "All the best Lay’s flavors in one bite!" The packaging describes the flavor as a mix of salt and vinegar, barbecue, and sour cream and onion, omitting any mention of ketchup. The packaging also highlights its Canadian roots, appealing to a trend among U.S. consumers for flavors that offer an "escapism" experience.

As of early 2025, Lay’s all dressed chips are set to become a permanent addition to the American flavor lineup. Despite a backdrop of rising tensions between Canada and the U.S., PepsiCo is optimistic about the flavor's reception. Although specific sales figures have not been disclosed, production has ramped up in six U.S. factories, and early feedback has been positive.

In Little Rock, Arkansas, local store owner Bill Woods reported having all dressed chips available for sale. After trying them again, he remarked, "They’re pretty good," indicating a favorable reception among American consumers.
