An Arby’s Classic Roast Beef Sandwich has thinly sliced roast beef served in a toasted sesame bun. Arby’s Sauce is commonly offered with it, but sauce and serving details can vary by restaurant, so ask for it on the side if you prefer.
Yes, the sandwich’s main filling is beef roast, cooked and sliced thin for serving. It is not ground beef shaped into slices, though the exact seasoning and preparation details are specific to the chain.
Arby’s Sauce is the chain’s tangy, tomato-based condiment, often served with roast beef sandwiches. It is different from Horsey Sauce, which has a sharper horseradish flavor; either can be requested separately.
The beef is roasted as a joint and then sliced thin before it goes into the sandwich. That cooking-and-slicing method gives the filling its characteristic tender, layered texture rather than the texture of a grilled burger patty.
An Arby’s Classic Roast Beef Sandwich pairs roast beef with a plain bun, while a Beef ’n Cheddar adds cheddar-style cheese sauce and an onion bun. The latter is creamier and has a more pronounced onion flavor.
Yes. Put thinly sliced cooked roast beef in a soft sesame bun and serve it with a tangy tomato-based sauce to echo the Arby’s version. Warm the meat gently with a splash of broth so the thin slices do not dry out.
The roast beef can retain a pink hue because of the meat and cooking process; color alone does not show that it is raw. The beef is cooked before it is sliced for the sandwich.
It can provide protein, but it is still a fast-food sandwich made with refined bread and may come with salty condiments. Pair it with water and a side salad, and go easy on extra sauce if you are watching your sodium intake.
Refrigerate an Arby’s Classic Roast Beef Sandwich promptly, within two hours, and eat it within a few days. Store the meat and bun separately when possible to limit sogginess, then reheat the meat until steaming hot.
An Arby’s Classic Roast Beef Sandwich is generally served warm, with roast beef in a toasted bun. If you take one to go, the meat and bun may cool during the trip, so eat it soon or refrigerate it promptly.

Arby’s Classic Roast Beef Sandwich is a US fast-food sandwich made with thinly sliced roast beef in a soft bun. The beef is roasted and sliced, giving it a savoury, meaty flavour that contrasts with the mild bread. It is typically ordered as a quick lunch or casual meal, often with fries and a drink; a side salad works well too.
For English-speaking readers, it is a convenient alternative to a burger when you want roast beef in a handheld format. It provides both carbohydrates from the bun and protein from the beef, with 13 g of protein per 100 g. To make the meal feel lighter, pair it with salad and go easy on additional sauces or fried sides.
