What Are French Dip Squares?
French Dip Squares are a modern twist on the classic French Dip sandwich. Instead of being served on a long roll, the signature flavors of roast beef, Swiss cheese, and savory au jus are baked between two buttery layers of crescent roll dough. Once baked, the dish is cut into squares, making it easier to serve at parties or family meals.
The flaky pastry provides the perfect contrast to the juicy beef and melted cheese, while the dipping sauce adds depth and richness. They’re essentially bite-sized French Dip sandwiches—transformed into a casserole-style dish for convenience and versatility.
The Origins of the French Dip Sandwich
The roots of French Dip Squares lie in the classic French Dip sandwich, which dates back to the early 20th century in Los Angeles. Both Philippe the Original and Cole’s claim to have invented the sandwich around 1908–1918. Regardless of the debate, the hallmark of the sandwich remains the same: thinly sliced beef piled onto French bread and dipped into au jus (a flavorful beef broth).
French Dip Squares take this tradition and give it a fun twist—perfect for entertaining, where handheld, shareable foods shine.
