Recreating Arby’s Beef N Cheddar at home is straightforward when you follow these steps:

1. Prepare the Ingredients: Gather all ingredients. Ensure the roast beef is thinly sliced and the cheddar cheese sauce is ready (you can buy it or make your own).
2. Toast the Rolls: Heat a skillet over medium heat. Add a little butter, and once melted, place the onion rolls, cut side down, in the skillet. Toast them until golden brown.
3. Heat the Beef: In a separate skillet, gently reheat the sliced roast beef over medium-low heat. You can season with salt and pepper if desired.
4. Warm the Cheddar Sauce: Heat the cheddar cheese sauce in a pan or microwave until it’s warm and smooth.
5. Assemble the Sandwich: Start with the toasted roll base, layer with warm roast beef, pour cheddar cheese sauce on top, and add any desired sauces or toppings.
6. Top and Serve: Place the other half of the roll on top, press gently, and your homemade Beef N Cheddar is ready to serve!
