How is the roast beef in Arby’s Large Roast Beef Sandwich prepared?
The beef is cooked as roast beef, sliced thinly, and assembled in the sandwich bun. The exact preparation and holding process can vary by restaurant, but it is served as sliced roast beef rather than a burger patty.
What is the difference between Arby’s Large Roast Beef Sandwich and the regular one?
The large version is a bigger serving, with more roast beef than the regular sandwich. Menu details and any accompanying toppings may vary between locations.
Does Arby’s Large Roast Beef Sandwich come with Arby’s sauce?
Not necessarily. Sauce availability and whether it is included can vary by location and order; you can ask for sauce on the side or leave it off when placing your order.
Is Arby’s Large Roast Beef Sandwich served hot or cold?

You cannot assume it is halal at every Arby’s location. Certification and meat sourcing vary by country and restaurant, so ask the specific location whether the sandwich is halal-certified.
How should I store leftover Arby’s Large Roast Beef Sandwich?
Refrigerate leftovers promptly in a covered container. The bun can become soft as it sits, so the sandwich is best eaten soon after storing rather than kept for an extended period.
Can you freeze Arby’s Large Roast Beef Sandwich?
You can freeze it, but the bun may thaw soft or soggy and the sandwich will lose some of its original texture. For a better result, freeze the roast beef separately from the bun if possible.
