If you’ve ever bitten into an Arby’s Beef and Cheddar sandwich and thought — I need to be able to make this at home — you are not alone. This is one of the most craved fast-food sandwiches in America, and for very good reason.
Thinly sliced, tender roast beef. A rich, creamy cheddar cheese sauce. That signature tangy-sweet red ranch sauce. All of it piled high on a soft, toasted onion bun. It’s a combination that just works — and now you can make it in your own kitchen in under 30 minutes, for a fraction of the cost.

What Makes This Copycat Recipe Authentic?
Most copycat versions of this sandwich miss one critical detail: Arby’s does not use their classic Arby’s sauce on the Beef and Cheddar. They use a red ranch sauce — a tangy, slightly sweet sauce that is completely different in flavor. Getting this right is the difference between a good sandwich and one that tastes exactly like the real thing.
The second key is the cheddar cheese sauce. It needs to be smooth, creamy, and rich — not gluey or grainy. We’re making it properly on the stovetop.
And the third secret? Steaming the roast beef rather than microwaving it. Steaming keeps every slice moist and tender. Microwaving dries out the edges and ruins the texture. Do not skip this step.
Ingredients
For the Sandwich
- 1 lb thinly sliced deli roast beef (ask for it sliced extra thin at the deli counter)
- 4 onion buns (onion Kaiser rolls work perfectly)
- 2 tablespoons unsalted butter, softened (for toasting the buns)
- 2 tablespoons water or beef broth (for steaming the beef)
For the Homemade Red Ranch Sauce
- ½ cup ketchup
- 2 tablespoons water
- 1 tablespoon apple cider vinegar
- 1 tablespoon light brown sugar
- ½ teaspoon onion powder
- ½ teaspoon garlic powder
- ¼ teaspoon paprika
- ¼ teaspoon Worcestershire sauce
- Pinch of salt
- Pinch of cayenne pepper (optional, for a little heat)
For the Homemade Cheddar Cheese Sauce
- 1 cup sharp cheddar cheese, freshly shredded (do NOT use pre-shredded)
- ½ cup Cheez Whiz
- ¼ cup whole milk
- ¼ teaspoon paprika
- Pinch of salt
Quick Shortcut: If you’re pressed for time, you can use store-bought Arby’s sauce (available at most grocery stores) and a jar of Rico’s nacho cheese sauce. The homemade versions taste noticeably better, but the shortcuts work on a busy weeknight.
Equipment You’ll Need
- Non-stick skillet with a lid (for steaming the beef)
- Small saucepan (for the cheese sauce)
- Small mixing bowl (for the red ranch sauce)
- Whisk
- Butter knife or spoon for spreading
- Cheese grater
How to Make Arby’s Beef and Cheddar Sandwiches
Step 1 — Make the Red Ranch Sauce
In a small mixing bowl, combine the ketchup, water, apple cider vinegar, brown sugar, onion powder, garlic powder, paprika, Worcestershire sauce, salt, and cayenne (if using). Whisk everything together until fully smooth and the sugar has dissolved.
Taste and adjust: want it tangier? Add a touch more apple cider vinegar. Prefer it sweeter? A tiny extra pinch of brown sugar does the trick. Set the sauce aside — it gets better as it sits.
Pro Tip: Make this sauce up to two weeks ahead and store it in a sealed jar in the refrigerator. The flavor deepens beautifully overnight.
Step 2 — Make the Cheddar Cheese Sauce
In a small saucepan over low heat, combine the Cheez Whiz, whole milk, and paprika. Stir constantly until the Cheez Whiz melts and the mixture is smooth and combined — about 2 to 3 minutes.
Add the freshly shredded sharp cheddar a handful at a time, stirring between each addition until fully melted and incorporated before adding more. Keep the heat on low — too much heat will make the sauce grainy and break apart.
Once the sauce is silky smooth, reduce to the lowest possible heat to keep it warm while you prepare everything else.
Important: Always shred your own cheddar from a block. Pre-shredded cheese contains anti-caking agents that prevent proper melting and result in a gritty, clumpy sauce.
Step 3 — Steam the Roast Beef
Layer the thinly sliced roast beef in a non-stick skillet. Add 2 tablespoons of water or beef broth. Cover with a lid and turn the heat to medium. Let the beef steam for 3 to 4 minutes — you’re not cooking it, just warming it through gently.
This method keeps the beef incredibly moist and tender, exactly the way it is at the restaurant. Never microwave the roast beef — it dries out the edges and loses that soft, melt-in-your-mouth quality.
Remove the lid and drain any excess liquid.
Step 4 — Toast the Buns
Butter the inside cut surfaces of each onion bun lightly. Place them butter-side down in a hot skillet over medium heat for about 60 to 90 seconds, until golden and lightly crisp. This toasting step creates a barrier that prevents the bun from going soggy once the sauces are added — don’t skip it.
Step 5 — Assemble the Sandwiches
Now comes the best part. Here is the correct layering order for an authentic Arby’s Beef and Cheddar:
- Spread 1 tablespoon of red ranch sauce on the bottom bun
- Pile on a generous portion of the steamed roast beef
- Spoon the warm cheddar cheese sauce generously over the top of the beef
- Add the top bun
Serve immediately. These sandwiches are at their absolute best the moment they are assembled and still warm.
Serving Suggestions
The Arby’s Beef and Cheddar is iconic on its own, but pair it with the right sides and you have a complete fast-food feast at home:
- Arby’s-style curly fries — available in the freezer section at most grocery stores; cook them in an air fryer for the crispiest result
- Classic coleslaw — the cool, creamy texture cuts through the richness of the cheese sauce beautifully
- Dill pickles — a few pickle slices on the side balance out the sweetness of the red ranch sauce
- Onion rings — golden and crispy, they are a natural companion
- Broccoli cheddar soup — a warm, comforting pairing on cold days
- Simple green salad — for those wanting something lighter alongside
Storage and Reheating Tips
Do not store assembled sandwiches. The bun will become soggy and the textures suffer. Store all components separately instead.
- Red ranch sauce: Keeps in a sealed jar in the refrigerator for up to 2 weeks
- Cheddar cheese sauce: Keeps in the refrigerator for up to 5 days. To reheat, place in a saucepan over medium-low heat with a splash of milk and whisk as it warms
- Steamed roast beef: Keeps in the refrigerator for up to 3 days. Reheat by steaming briefly in a covered skillet with a tablespoon of water
- Assembling ahead for parties: Prepare all components in advance and set them up as a build-your-own sandwich station. Guests rim their own buns and pile on their own sauces
Frequently Asked Questions
Can I use regular hamburger buns instead of onion buns? Yes, absolutely. Sesame seed buns are a great alternative. The onion buns do add a distinct flavor that makes the sandwich taste more authentic, but any soft sandwich bun will work perfectly.
What type of roast beef should I buy? Ask the deli counter for their thinnest slice setting. Hillshire Farm Ultra Thin Sliced Roast Beef and Land O Frost are popular packaged options. The key is thin, delicate slices — thick chunks of beef will change the entire texture of the sandwich.
Can I use store-bought Arby’s sauce instead of making the red ranch sauce? You can, but be aware that the Arby’s sauce sold in stores is not the same as the red ranch sauce used on the Beef and Cheddar at the restaurant. Store-bought Arby’s sauce works as a quick substitute but the flavor profile is different — tangier and less sweet.
Can I freeze the sauces? The red ranch sauce freezes well in an airtight container for up to 3 months. The cheese sauce does not freeze well — it tends to separate and become grainy when thawed. Make the cheese sauce fresh each time.
How do I keep sandwiches warm for a party? Assemble the sandwiches, wrap each one tightly in aluminum foil, and keep them in an oven set to 160°F (70°C) for up to one hour. They stay warm and the flavors meld together beautifully.
Is this recipe gluten-free? The fillings can be made gluten-free easily. Simply use a certified gluten-free sandwich bun, verify that your chosen roast beef brand is gluten-free, and check that your Worcestershire sauce is gluten-free (most are, but some brands vary).
