The drumbeat began about five years ago, as the restaurant industry started to recover from the recession. The sound was faint, but chefs noticed. Openings for junior jobs like prep cook and line cook were taking longer to fill, and the applicants had weaker skills. Cooks with just one or two years of experience were applying for jobs better suited to 10-year veterans. Stagiaires, aspiring cooks who once begged for unpaid internships, were leaving after a day of work, or not showing up at all.

But the chefs’ concern was muted: After all, the industry was surging back, producing more ambitious restaurants, new culinary destinations, higher check averages and ever more culinary school graduates, all driven by Americans’ heightened interest in food and the glamorous image of the professional kitchen.

In the last year, though, the sound has become deafening. At conferences, over beers and on social media, chefs and restaurateurs are openly worrying (not to say complaining) about a crisis-level shortage of cooks. In scores of interviews via phone and email, chefs and restaurateurs confirmed that the shortage has affected their hiring. They included Christopher Kostow of the Restaurant at Meadowood in the Napa Valley, Dominique Crenn of Atelier Crenn in San Francisco, Jeff Michaud of Vetri Family Restaurants in Philadelphia and Andrew Carmellini of Locanda Verde in New York, and large-scale restaurateurs like Ralph Scamardella of Tao Group, Kevin Boehm of Boka Restaurant Group in Chicago and Chris Himmel of Himmel Hospitality Group in Boston.
