The French dip sandwich, a classic American creation, has a history rooted in the early 20th century. Legend has it that the sandwich originated at Philippe’s, a historic restaurant in Los Angeles. In 1918, Philippe Mathieu accidentally dropped a French roll into a roasting pan filled with juices from the meat he was cooking. Rather than discarding the soaked roll, he served it to a police officer, and the French dip sandwich was born. The popularity of this flavorful creation quickly spread, and Philippe’s, still operating today, proudly claims to be the originator of the French dip.
The hallmark of a French dip sandwich lies in its simplicity and the au jus dipping sauce that accompanies it. Typically made with thinly sliced roast beef or sometimes lamb, the sandwich is served on a French roll. What sets it apart is the technique of briefly submerging the entire sandwich or just the top half in the meaty pan juices, creating a delectably moist and savory experience. The au jus, a flavorful broth created during the roasting process, adds depth and richness to each bite.
Variations of the French dip have emerged over the years, with different meats, cheeses, and condiments making their way into the sandwich, but the essence of the French dip remains its succulent meat and the delightful au jus that elevates the sandwich from a mere lunch option to a culinary classic cherished by sandwich enthusiasts around the world.
