National Crouton Day is observed worldwide on May 13 each year, celebrating the often-overlooked food topping known as croutons. These small pieces of fried or toasted bread, typically seasoned with garlic, herbs, or cheese, add flavor and texture to salads, soups, and other dishes. The term "crouton" originates from French cuisine, derived from the word "croûte," meaning crust. National Crouton Day was established in 2015 by Rothbury Farms, a bakery that produced croutons until its discontinuation in February 2022. Celebrations may include topping salads or soups with croutons, using them in various dishes, or enjoying them as snacks. Participants are encouraged to share their experiences on social media using the hashtags #NationalCroutonDay and #CroutonDay.
