Ingredients for arbys cheese sauce
Nine simple ingredients transform into that iconic Arby's cheese sauce everyone craves.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ½ cup | Cold cubes for even melting |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Shredded, not pre-shredded |
| Whole Milk 🥛 | 1 cup | Full-fat for creaminess |
| All-Purpose Flour 🌾 | 1 tbsp | For thickening |
| Dried Mustard 🌶️ | ½ tsp | For signature tang |
| Garlic Powder 🧄 | ¼ tsp | For subtle depth |
| Onion Powder 🧅 | ¼ tsp | For savory balance |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ¼ tsp | Freshly cracked |
| White Vinegar 🍶 | ½ tsp | For tangy kick |
The cheddar is non-negotiable—sharp white cheddar gives that signature tang. Walmart or Kroger carry good blocks for grating yourself, and trust me, it's worth it. The butter? Cold cubes melt slower for smoother sauce. I grab Land O'Lakes unsalted because it's consistent, but any brand works. For the milk, whole milk is a must—skim makes the sauce separate. Pro tip: shred the cheese yourself; pre-shredded has anti-caking agents that make the sauce grainy.
No sharp cheddar? Colby Jack works in a pinch, but it won't taste quite the same. Out of white vinegar? Lemon juice at half the amount gives a similar tang. The flour is key for that velvety texture—don't skip it. Want extra tang? Add a pinch more mustard. For a spicier version, swap half the black pepper for cayenne. This sauce reheats beautifully, so make a big batch—it disappears fast. Store leftovers with a thin layer of milk on top to prevent skin formation.
This sauce keeps 5 days in the fridge and freezes for 3 months. For freezing, portion into ice cube trays—perfect for topping single servings later. The secret to no lumps? Low and slow heat while stirring constantly. If it gets too thick, just whisk in a splash of warm milk. The flavor actually improves overnight as everything melds together. Make extra for burgers, hot dogs, or even grilled cheese—your whole menu will thank you.

Step-by-step instructions for Arby's cheese sauce
Here's how to make that signature ultra-creamy, tangy sauce that makes everything taste like a loaded Arby's order.
Melt the Butter and Prepare the Base
In a medium saucepan, melt the 0.5 cup unsalted butter over medium heat. Watch closely as it melts completely, then stir in the 1 cup whole milk and 1 tbsp all-purpose flour. This creates a smooth, velvety base that will thicken beautifully as we cook.
Bring the mixture to a gentle simmer, stirring constantly with a wooden spoon or whisk. You'll see it begin to thicken slightly—this is where the magic starts. Keep the heat at medium-low to prevent scorching. The sauce should bubble softly but not boil vigorously. This step is all about building that creamy foundation.
Add Cheese and Seasonings
Once the milk-butter mixture is smooth and slightly thickened, reduce the heat to low and gradually add the 2 cups sharp white cheddar cheese. Stir constantly to ensure the cheese melts completely and creates a silky, lump-free texture. If you notice any lumps forming, keep whisking vigorously until they disappear.
Now add the 0.5 tsp dried mustard, 0.25 tsp garlic powder, 0.25 tsp onion powder, 0.5 tsp salt, and 0.25 tsp black pepper. These seasonings work together to create that signature Arby's flavor profile—tangy, savory, and just a little bit funky. Stir well to distribute the spices evenly throughout the sauce.
Finish with Vinegar for Tang
This is where the sauce gets its signature tang—add the 0.5 tsp white vinegar and stir one final time. The vinegar brightens the flavors and cuts through the richness of the cheese. Taste the sauce and adjust the seasoning if needed. You might want to add a pinch more salt or a dash of black pepper to taste.
Continue simmering on low heat for 3-5 minutes, stirring occasionally, until the sauce reaches your desired consistency. It should coat the back of a spoon smoothly but not be overly thick. If it's too thick, thin it with a splash of warm milk. If it's too thin, simmer a bit longer to thicken it further.
Strain and Serve
For the smoothest, most luxurious texture, strain the sauce through a fine-mesh sieve into a clean saucepan. This removes any remaining lumps and gives you that ultra-creamy, restaurant-quality finish. Return the sauce to low heat and keep it warm until ready to serve.
Serve immediately over loaded fries, as a dip for mozzarella sticks, or drizzle generously over burgers and sandwiches. The sauce should be warm and glossy, with a perfect balance of creaminess and tang. Store any leftovers in an airtight container in the refrigerator for up to 5 days, or freeze for up to 3 months. Reheat gently on the stovetop, stirring frequently to prevent scorching.
Pro Tips For Making Arbys Cheese Sauce
- Melt Butter Slowly: I learned this the hard way—dumping cold butter into the pan at medium heat makes the sauce seize up like glue. Instead, melt the butter first over low heat until it’s just warm and liquid, then whisk it into the flour. That way, the roux starts smooth and doesn’t turn into a clumpfest.
- Grated, Not Cubed: Cubed cheddar? Nope. Sharp white cheddar needs to be freshly grated—pre-shredded stuff has anti-caking agents that make the sauce grainy. Use a box grater, and if you’re lazy, buy pre-grated but pulse it in a food processor to break up those annoying clumps. Your sauce will thank you.
- Low and Steady Heat: High heat = scrambled cheese. Once the milk’s in, drop the heat to low and let it simmer gently. Stir constantly, but not frantically—just enough to keep it from sticking. Sounds boring, but this is the thing that matters most for that silky, restaurant-quality texture.
- Mustard Last: Add the dried mustard too early, and it’ll burn before the cheese even melts. Wait until the sauce is thickened and off the heat—just stir it in at the end. A pinch (½ teaspoon) is enough; you’re not making a glaze. This keeps the flavor bright without bitterness.
Perfect pairings for this dish
Loaded Fries Dream
This cheese sauce was made for Arby's iconic loaded fries—crispy golden fries smothered in warm, gooey sauce, melted mozzarella, and chopped bacon. I like to pile 4-5 fries on a plate, drizzle with sauce, then top with ¼ cup shredded mozzarella and 2 tbsp crumbled bacon.
Broil for 2-3 minutes until the cheese is bubbly and golden. 🔥
Burger Topping Magic
Transform any burger into a cheesy masterpiece by slathering 2 tbsp sauce on the top bun before adding your patty. For extra decadence, melt 1 slice of cheddar on top of the patty, then add the sauce-drenched bun.
Pair with crispy onion strings and a side of Arby's sauce for that full restaurant experience.
Mac and Cheese Upgrade
Stir ½ cup sauce into 2 cups cooked elbow macaroni mixed with 1 cup shredded cheddar and ½ cup whole milk. Top with breadcrumbs and broil for 3-4 minutes until golden.
The sauce adds that signature tangy depth that takes mac and cheese to the next level. Perfect for a cozy weeknight dinner! 💫

Serve warm in a small crockpot or slow cooker as a dip for mozzarella sticks, chicken tenders, or soft pretzel bites. The creamy texture clings beautifully to foods, making every bite irresistible. For extra flair, garnish with chopped parsley or a sprinkle of paprika. 🌟
Sandwich Game-Changer
Spread 1-2 tbsp sauce on the inside of a toasted bun before assembling your sandwich. It works especially well with pulled pork, grilled chicken, or meatball subs.
The sauce adds moisture and that signature tang that keeps you coming back for more. Trust me, it’s a game-changer for sandwiches! ⚡
Dessert Twist
Yes, you read that right! Warm this sauce over vanilla ice cream or brownies for a sweet-and-savory dessert. The tangy, creamy flavor balances the sweetness perfectly. Drizzle lightly over warm chocolate chip cookies for a grown-up treat that’ll surprise your taste buds. 🍦

Frequently asked questions
Why does this cheese sauce need flour?
The 1 tbsp flour creates that signature velvety texture by gently thickening the sauce without making it grainy. It acts like a natural emulsifier, helping the cheese and milk blend smoothly. Without it, you'll get a thinner, less luxurious consistency that doesn't cling as beautifully to foods.
Can I make this sauce without dairy?
For a dairy-free version, swap the butter for vegan butter or coconut oil, use dairy-free milk, and replace the cheddar with vegan cheddar shreds. The tangy flavor will still shine, though the texture will be slightly lighter. The flour and vinegar remain essential for that signature balance.
How do I fix lumps in my cheese sauce?
If you get lumps, immediately whisk vigorously or use an immersion blender to break them up. For stubborn lumps, strain the sauce through a fine-mesh sieve before serving. The key is to keep heat low and stir constantly while melting the cheese—this prevents clumping from the start.
What's the best way to reheat leftover sauce?
Gently reheat on the stovetop over low heat, stirring constantly, until just warm. Microwaving can make it grainy, and high heat causes separation. For extra creaminess, add a splash of warm milk or water while reheating. Always store leftovers with a thin layer of milk on top to prevent skin formation.
Can I use this sauce in a slow cooker?
Yes! Combine all ingredients in your slow cooker on low heat for 1-2 hours, stirring occasionally. The slow cooking prevents scorching and creates an even smoother texture. It's perfect for keeping warm during parties or game days—just stir before serving to restore that perfect consistency.
