This Double Roast Beef has two times the amount of our signature roast beef on it than the Roast Beef Classic. Perfect for those times when you're twice as hungry or would just like too much roast beef on a one sandwich.
Arby's Double Roast Beef runs $6.99 with 510 cal, and it piles on two times the signature roast beef found on the Classic Roast Beef. Arby's pitches it for days when you are twice as hungry, or when you simply want what it cheerfully calls too much roast beef on one sandwich.
Beef is the star and nearly the whole cast. The thin slices fold over each other in a tall, loose stack, so the sandwich stays tender instead of dense. With twice the meat, the savory roasted flavor comes through stronger than on the Classic, and the juices from the beef soak a little into the bun. Since the base sandwich carries no cheese or vegetables, the sauces you add make a bigger difference here. A squeeze of tangy Arby's Sauce brightens all that beef, while creamy Horsey Sauce spreads a sharp horseradish heat across the stack. Try one sauce on each half to taste both.
Picture a sandwich that looks like the Classic after a growth spurt: the same round bun shape with beef bulging out past the edges. It is still easy to hold in one hand, which makes it a good pick for eating in the car or at a desk. The Double suits anyone who wants a meat forward lunch without the cheese sauce of a Beef 'n Cheddar.
The Double Roast Beef calories reflect the extra meat, and the protein climbs with it to 38 grams. That is a big step up from the Classic for only a modest bump in price, which makes it one of the stronger protein per dollar options on the Arby's roast beef menu. Sodium rises as well, so balance the rest of your meal with a lighter side if salt matters to you.
How much is the Double Roast Beef compared with the other sizes? The Double fills the gap: the Classic sells for $5.29, while the bigger Half Pound Roast Beef runs $9.29. The Double Roast Beef Meal wraps in fries and a drink for $11.49. Austin, TX is where we recorded these numbers, so treat them as a guide for other cities.
A warm side of White Cheddar Mac 'n Cheese adds the creamy cheese element this sandwich skips. For dessert, an Cherry Turnover brings a sweet, fruity finish after all that savory beef.

This weeknight Double Roast Beef skips the oven and relies on good deli roast beef, warmed gently in seasoned broth and stacked 6 ounces high. Both sauces are stirred together cold, so dinner for two takes about 15 minutes.
All steps done. Enjoy your homemade Double Roast Beef.
Serve with a creamy mac and cheese or a crisp coleslaw, plus a cold drink to tame the horseradish.

$5.29 We see $6.99 on the board at an Austin, TX Arby's, and the meal version lists at $11.49. Other stores differ by a little.
One Double Roast Beef has 510 cal without added sauce. The Classic has 360 cal, so the extra beef adds a noticeable amount.
Arby's says it has two times the amount of its signature roast beef compared with the Classic Roast Beef. Everything else about the sandwich stays simple, so the difference is all meat.
Expect 38 grams of protein, far more than the 23 grams in the Classic and close to the 39 grams in the Double Beef 'n Cheddar.
The Double is the middle size and costs less, while the Half Pound Roast Beef is the largest roast beef sandwich Arby's makes at $9.29. Pick the Double for a big lunch and the Half Pound when you are truly starving.
