Arby's-Style Beef 'n Cheddar Stackers

Instructions

1. 1

   Prepare the Red Ranch Sauce: In a small bowl, whisk together ketchup, mayonnaise, Worcestershire sauce, garlic powder, onion powder, black pepper, and cayenne pepper (if using). Cover and refrigerate to allow flavors to meld while you prepare the rest of the ingredients.

2. 2

   Make the Cheddar Cheese Sauce: In a medium saucepan over medium heat, melt the butter. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux (a thick paste).

3. 3

   Gradually whisk in the milk until smooth. Bring to a simmer, whisking frequently, until the sauce thickens. Reduce heat to low.

4. 4

   Add the shredded cheddar cheese, garlic powder, onion powder, and paprika to the saucepan. Stir until the cheese is completely melted and smooth. Season with salt and pepper to taste. Keep warm over very low heat, stirring occasionally. If it becomes too thick, add a splash more milk.

5. 5

   Warm the Roast Beef: In a large skillet over medium-low heat, add the beef broth or water. Add the thinly sliced roast beef, separating the slices as you go. Gently warm the beef for 2-3 minutes, just until hot but not overcooked or tough. Do not boil.

6. 6

   Toast the Buns: Lightly toast the sesame seed buns in a toaster, under a broiler, or in a dry skillet until golden brown and slightly crispy.

7. 7

   Assemble the Sandwiches: On the bottom half of each toasted bun, pile a generous amount of warm roast beef. Drizzle generously with the warm cheddar cheese sauce. Spoon or spread a dollop of the Red Ranch sauce over the cheese. Place the top bun on top.
