November 12 is National French Dip Day, honoring the beloved sandwich known for its savory flavors and satisfying dip. The French dip sandwich, also called a beef dip, is a hot sandwich consisting of thinly sliced roast beef layered on a French roll or baguette, served with a side of au jus—a flavorful beef broth or pan drippings used for dipping.

The origins of the French dip sandwich trace back to early 20th-century Los Angeles. Two rival restaurants, Philippe the Original and Cole’s Pacific Electric Buffet, both claim to have invented the sandwich in the late 1900s. According to one story, Philippe Mathieu, owner of Philippe the Original, accidentally dropped a French roll into a pan of beef drippings while preparing a sandwich. The customer enjoyed the sandwich so much that it became a menu staple. Another version attributes the invention to Cole’s, where a similar scenario reportedly occurred.

Despite the disputed origins, the French dip sandwich quickly became a popular menu item and has since gained fans worldwide.

Today, there are many variations of the classic French dip. While the traditional version features roast beef, other meats like turkey, lamb, or pork are sometimes used. Some versions include melted cheese, caramelized onions, or horseradish sauce for added flavor. The au jus can also be enhanced with wine or herbs for a richer dipping experience.

National French Dip Day is the perfect opportunity to indulge in this comforting, flavorful sandwich. Whether enjoyed at a local diner or made at home, the French dip remains a timeless favorite. So, grab a sandwich, dip into some warm au jus, and savor the delicious history of the French dip.
