This is the sandwich that put roast beef on the map. Our classic roast beef is thinly sliced and piled on a toasted sesame seed bun. Try it with our delicious Arby's Sauce, or for an extra kick go with the zesty Horsey Sauce.
Arby's Classic Roast Beef costs $5.29 and has 360 cal, a plain and simple build of thinly sliced roast beef piled on a toasted sesame seed bun. Arby's calls it the sandwich that put roast beef on the map, and every other beef sandwich on the board traces back to this one.
The appeal is how little stands between you and the meat. There is no cheese and no lettuce, just a soft heap of shaved beef with a mild, savory roast flavor and a tender bite that pulls apart easily. The sesame seed bun is toasted for a light crunch on the cut side, and the seeds add a faint nutty note. Because the sandwich arrives unsauced in its basic form, you decide how it tastes. Arby's Sauce adds a tangy, slightly sweet tomato flavor, while Horsey Sauce brings a creamy horseradish heat that clears your nose a little on the first bite.
It looks humble: a round bun, a fringe of pink beef around the edge, a scatter of sesame seeds on top. That simplicity is the point. It is a great choice for picky eaters, for kids who want plain meat on bread, and for anyone who likes to customize with sauces at the table.
The Classic Roast Beef calories sit at the lighter end of the Arby's roast beef menu, and you still get 23 grams of protein. That balance makes it a smart choice for a lighter lunch or a quick snack between errands. It also costs less than the Beef 'n Cheddar, so it works well when you want two sandwiches or plan to add a side.
The Classic Roast Beef price makes it the entry point of the roast beef line. If one is not enough, the Double Roast Beef doubles the meat at $6.99. Add fries and a drink through the Classic Roast Beef Meal for $9.79. Our Austin, TX store sets the baseline for these numbers, and yours will differ slightly.
To round out the order, a side of Mozzarella Sticks adds the cheese this sandwich leaves out, and a Classic Lemonade cuts through the horseradish bite of Horsey Sauce.

This copycat Classic Roast Beef starts with a whole eye of round roasted low and slow, then sliced paper thin like the Arby's version. You also make both sauces from pantry staples: a tangy Arby's style sauce and a creamy Horsey Sauce with prepared horseradish.
All steps done. Enjoy your homemade Classic Roast Beef.
Set out the beef, buns and both sauces so everyone builds their own, and add potato chips or curly fries on the side.

$6.99 Austin, TX pricing puts the Classic Roast Beef at $5.29, the lowest priced sandwich in the roast beef lineup. Expect a small swing at other locations.
The sandwich has 360 cal before any added sauce. Packets of Arby's Sauce or Horsey Sauce add more, so count them if you track calories closely.
Arby's recommends its signature Arby's Sauce, and for more kick, Horsey Sauce. Underneath, it is only shaved beef and a toasted sesame bun, so the sauce is your call.
One Classic Roast Beef has 23 grams of protein. That matches the Classic Beef 'n Cheddar, which has 23 grams but adds cheese sauce and more calories.
The Double Roast Beef carries twice the signature roast beef of the Classic. It costs $6.99 and has 510 cal, so pick it when you are hungrier.
