Roast beef. Swiss. Sub roll. French au jus sauce. It's half the countries in the world on one sandwich.
Arby's Classic French Dip & Swiss sells for $6.89 and totals 600 cal, pairing roast beef and Swiss cheese on a sub roll with a cup of French au jus sauce for dunking. Arby's sums it up in four short lines, roast beef, Swiss, sub roll, au jus, and jokes that it puts half the countries in the world on one sandwich.
The dip is what makes this order different from every other beef sandwich at Arby's. Au jus is a thin, savory beef broth, and dunking the end of the sandwich turns the roll soft and juicy while adding a rich, salty depth to the beef. Swiss cheese melts over the meat with a mild, nutty flavor that never fights the broth. The sub roll gives you a longer, narrower sandwich with a chewy crust, which is exactly what you want for dipping, since a soft round bun would fall apart in the cup.
Expect a long roll with roast beef tucked inside, pale Swiss melted over the top, and a small container of dark brown jus on the side. The routine is simple: dip, bite, repeat. It suits a sit down lunch, a cold day when something warm and brothy sounds good, or anyone who grew up on diner French dips and wants a quick version.
The Classic French Dip & Swiss calories sit higher than the Classic Roast Beef, mostly from the cheese, the larger roll and the jus. It also brings 29 grams of protein. Sodium is on the high side because both the beef and the au jus are salty, so you can dip lightly if that matters to you. On the Arby's roast beef menu, it is the only sandwich built around a dipping sauce.
On price, the Classic French Dip & Swiss costs more than the Classic Beef 'n Cheddar at $6.29, reflecting the sub roll and the jus. Pair it with fries and a drink through the Classic French Dip & Swiss Meal for $11.39. The numbers on this page were taken at an Austin, TX Arby's, so use them as a reference point.
Fries are a natural partner here because they can take a dunk in the jus too. Order Curly Fries and use the leftover broth as a dip, or go with Potato Cakes for a crisp contrast to the soft, soaked roll.

A homemade French Dip & Swiss needs only four components, the same ones Arby's lists: roast beef, Swiss, a sub roll and au jus. The jus simmers from beef broth and a few pantry seasonings in about 15 minutes, and the sandwiches melt under the broiler.
All steps done. Enjoy your homemade Classic French Dip & Swiss.
Serve each sandwich with its own cup of jus and a side of fries or potato wedges for dunking.

$5.29 Our Austin, TX store lists the sandwich at $6.89. The combo version comes to $11.39, and both figures move slightly from city to city.
The sandwich has 600 cal. That is more than the Classic Roast Beef at 360 cal, largely because of the Swiss, the sub roll and the au jus.
Four things make it up: roast beef, Swiss cheese, a sub roll and a cup of French au jus. As the French Dip name says, the au jus is there for dipping each bite.
Au jus is a thin, savory beef broth served warm for dipping. It softens the sub roll and adds a rich, salty beef flavor to each bite of the sandwich.
You get 29 grams of protein, from the roast beef and the Swiss cheese. That is a bit higher than the Classic Roast Beef, which has 23 grams.
