Making the Arby's Beef and Cheddar sandwich at home is easier than it sounds: Most of the recipe happens in the oven, and once roasted, the beef is sliced and served with a quick and easy cheese sauce and a ketchup-based sauce that comes together while the beef cooks. The Red Ranch, which is less like a ranch and more like a salad dressing or barbecue sauce, adds a tangy flavor that complements the beef and ties together the rich elements of the stacked sandwich.
Roast beef is the classic Arby's staple with a unique, unconventional preparation that locks in moisture and delivers a powerful umami punch. This, paired with a sharp, melty, and gooey cheddar cheese sauce is already a winning combination. Arby's zesty red ranch is the mysterious special sauce that completed the trifecta and dazzled our tastebuds; despite its name, it's a sweeter, tangier, and tomato-based sauce.
