This copycat Arby’s Beef and Cheddar sandwich is one of the tastiest sandwiches I’ve ever had and one of the easiest copycat recipes to make. The cheddar roast beef sandwich is always my go-to when we zip through the Arby’s drive thru. There’s nothing quite like the combination of tender slices of tender roast combined with homemade melted cheddar and the signature tangy red ranch sauce. Each bite delivers a perfect balance of rich beef with creamy cheese. The flavor combination is a win for Arby’s and now a win for you in your own kitchen!
Ingredients in Arby’s Beef and Cheddar
This Arby’s roast beef sandwich is made with simple, easy to find ingredients, and comes together quickly. Here’s all you need:
For the Sandwich
Roast beef – One pound of deli roast beef, rare. I ask the deli counter at my grocery store to slice the meat super thin. That way it tastes just like the restaurant. Onion hamburger buns – you can use regular buns if you like but the onion buns will elevate the flavor and give you that exact taste that the original Arby’s roast beef sandwich offers. Warm them in the oven before assembling, if you like.
Arby’s Cheddar Copycat Recipe
Butter – two tablespoons unsalted butter Flour – two tablespoons of regular, all purpose flour Milk – three quarters of a cup. I like using whole milk for this recipe to make the sauce extra creamy, but you can use any kind you like. Cheddar cheese – one cup sharp cheddar cheese, shredded by hand. Avoid pre-shredded cheese; it just doesn’t melt as well and won’t give you that creamy texture. Salt and pepper – to taste
Arby’s Secret Sauce Recipe
Ketchup – half a cup of your favorite brand of regular ketchup Apple cider vinegar – one tablespoon. Find it next to the regular vinegar in the grocery store. It has a deeper, tangier flavor than regular white vinegar. Brown sugar – one tablespoon, or a bit more if you like a sweeter sauce. Water – a couple of tablespoons to thin out the sauce. Salt – just a pinch to taste Garlic powder – a quarter teaspoon Onion powder – a quarter teaspoon Frank’s Hot Sauce – to taste. This is optional but if you like a spicy kick, this is the perfect ingredient.
Steps to the Perfect Arby’s Beef and Cheddar
This sandwich comes together in just a few simple steps:
Homemade Cheese Sauce
This homemade cheese sauce is so good and can be used to dip French fries, drizzle over chicken, and of course, this Arby’s roast beef sandwich. But there are some tips to making it creamy and not lumpy:
Shred the cheese by hand to make the sauce because the package of shredded cheese is tossed with cornstarch and it won’t melt into the creamy sauce the same way. If your milk and cheese mixture becomes too thick, add more milk and keep whisking until smooth. This also works for reheating the cheddar sauce. Place the cold sauce in a pan over medium low heat with some milk and whisk together as it warms up.
What to serve with the Beef and Cheddar Sandwich
It’s fun to serve these Arby’s Beef and Cheddar sandwiches with curly fries. They actually sell Arby’s curly fries in the freezer section of the grocery store. Or you can make your own with potatoes and an air fryer.
Additional ingredients to top your sandwich
I love eating the Beef and Cheddar just like it is, with a little extra Arby’s sauce for dipping, but there are endless options to make your sandwich the way you like it:
Shredded lettuce Grilled onions Sliced tomatoes Diced jalapenos Onion straws, or fried onion rings
