The recipe card below has a full list of ingredients and amounts.

  • Homemade Arby’s Sauce: All you have to do to make the sauce that comes in those little packets is whisk it up in a bowl using a carefully measured mixture of ketchup, vinegar, mayo, sugar, and spices!
  • Roast Beef: The best option for making this sandwich imitation is thinly sliced deli roast beef, which is comparable to what Arby’s serves. If purchasing the pre-packaged beef is more convenient, you can also obtain this from the deli counter. For four sandwiches, get a pound of roast beef.
  • The secret to warming the beef without drying it out is to use beef broth. We’ll put the beef and broth on the stove to simmer for a very short time.
  • Onion Rolls: A soft roll with onions atop is served with an Arby’s Beef and Cheddar. Seek out sandwich rolls with onions, or substitute your preferred soft rolls.
  • Cheese Sauce: Since making cheese sauce from scratch is so simple, we won’t be purchasing it premade. All you need is butter, flour, milk, sharp cheddar cheese, and a small pinch of salt.

Ask the person selling you the roast beef at the deli counter to “shave,” or slice it as thinly as they can!


Since this is a beef and cheddar sandwich, medium or mild cheddar will also work well for that traditional flavor.

However, feel free to experiment with any other type of cheese you like; just make sure it’s a good melting cheese!
