National Macaroni Day is celebrated on July 7 each year, primarily in the United States. This unofficial holiday honors macaroni, a small, tube-shaped pasta that originated in Naples, Italy. The day is particularly associated with the popular dish macaroni and cheese, which was introduced to the U.S. by Thomas Jefferson in the late 18th century. Traditionally, macaroni and cheese is made with elbow macaroni and a cheese sauce, often baked to create a comforting casserole. People celebrate by cooking various macaroni dishes, participating in macaroni cook-offs, and engaging in macaroni-themed arts and crafts. Sharing photos of macaroni creations on social media with the hashtag #NationalMacaroniDay is also a common practice.
