Ingredients for arby's cheddar cheese sauce
Seven ingredients transform into Arby's signature ultra-creamy sauce—no burnt taste in sight.
| Ingredient | Amount | Notes |
|---|---|---|
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, block preferred |
| Heavy Cream 🥛 | 1 ½ cups | Full-fat for richness |
| All-Purpose Flour 🌾 | 1 tbsp | As stabilizer for cling |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for slow melt |
| Yellow Onion 🧅 | ¼ whole | Finely chopped, no color |
| Garlic Cloves 🧄 | 2 cloves | Minced, for depth |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Adjust to taste |
The cheddar is non-negotiable—Kraft 2% or sharp white cheddar from the deli section delivers that signature tang. Walmart or Kroger usually stock the Kraft brand, but any sharp variety works. Avoid pre-shredded (it's coated with anti-caking agents that make the sauce grainy). The heavy cream? Store-brand is fine—just make sure it's full-fat. For the butter, Land O'Lakes or Earth Balance both work, but keep it cold in cubes. That slow melt is key to avoiding lumps. The onion and garlic? Yellow onions add sweetness without overpowering, and fresh garlic (not jarred) gives that authentic depth.
No sharp cheddar? Pepper Jack at half the amount adds heat, but it changes the flavor profile. Heavy cream substitute? Half-and-half plus 1 tbsp extra butter keeps it rich. Short on butter? Olive oil at half the amount works in a pinch, but it's not ideal. The flour is crucial—it's what gives the sauce that signature cling without altering the flavor. King Arthur or Bob's Red Mill are great choices. If you're gluten-free, cornstarch at the same amount works, but the texture will be slightly different. The salt? Diamond Crystal is ideal because it's less salty than table salt—use it as directed, then adjust to taste.
This sauce reheats beautifully—just warm over low heat with a splash of milk or cream to restore that velvety texture. Keeps for 5 days in the fridge, 3 months frozen. For freezing, cool completely first, then store in airtight containers. Double the batch and freeze half—perfect for lazy weeknights. The sauce thickens as it cools, so thin with a splash of milk if needed. Trust me, it's worth the extra minute of stirring.
Why You'll Love This Recipe

- Sauce for Everything: Dip fries? Check. Toss with mac and cheese? Done. Even slather it on burgers or baked potatoes. That creamy, cheesy goodness works anywhere, and I’ve never had to scrap a batch because it didn’t fit.
- Leftovers That Last: This sauce thickens perfectly and reheats like a dream. I make a double batch on Sundays—one for immediate use, one to freeze. Thaw it in the fridge overnight, and it’s just as smooth the next day. (Yes, even on a Tuesday night.)

Step-by-step instructions for Arby's cheddar cheese sauce
Here's how to make that signature ultra-creamy sauce without any lumps or burnt bases.
Melt Butter and Sauté Aromatics
Place the 0.5 cup unsalted butter in a medium saucepan over medium-low heat. Let it melt completely, then add the 0.25 whole yellow onion that's been finely chopped. Cook the onion for 5 minutes until it becomes completely translucent and loses its raw smell. This step builds the sauce's flavor foundation without letting the onion brown or burn.
Next, add the 2 cloves garlic cloves that you've minced. Cook for another 1 minute until the garlic is fragrant but not colored. The key here is patience—overcooking garlic turns it bitter, and you want that clean, sweet onion and garlic flavor to shine through in the final sauce. Keep the heat at medium-low to prevent any burning.
Add Flour and Create a Smooth Base
Lower the heat to low and sprinkle in the 1 tablespoon all-purpose flour. Stir constantly for 1-2 minutes until the flour is completely dissolved and the mixture turns into a smooth, pale roux. This step is crucial for thickening the sauce and preventing any lumps later on.
Here's where I like to add a splash of the 1.5 cups heavy cream—just 2 tablespoons at first—to help break up any potential lumps and create a silky base. Stir vigorously for 30 seconds until everything is perfectly smooth. The roux should now coat the back of a spoon, indicating it's ready for the next step.
Incorporate Cheese and Cream Gradually
Remove the saucepan from heat and reduce the heat to low. Begin adding the 1.5 cups heavy cream in small increments, whisking constantly to prevent any separation. After each addition, let the mixture come to a gentle simmer before adding more. This gradual approach ensures the sauce emulsifies properly and remains ultra-smooth.
Once all the heavy cream is incorporated, return the saucepan to low heat and begin adding the 1.5 cups sharp cheddar cheese in small handfuls. Stir continuously until each addition melts completely before adding the next. The cheese should dissolve smoothly, creating a velvety texture. If you notice any lumps forming, immediately whisk them out—this is your chance to fix any imperfections before they set.
Season and Simmer to Perfection
Add the 0.5 teaspoon diamond crystal kosher salt and stir well. Taste the sauce and adjust the salt if needed—remember, the cheese is already quite salty, so go easy. Return the sauce to low heat and let it simmer gently for 5-7 minutes, stirring occasionally. This step allows the flavors to meld together and ensures the sauce reaches its ideal consistency.
The sauce is ready when it's smooth, glossy, and coats the back of a spoon without being too thick. It should be creamy but not heavy, with a rich, cheddar flavor that's not overpowering. If it's too thick, whisk in 1-2 tablespoons of warm milk or cream to reach your desired consistency. Remove from heat immediately to prevent any scorching.
Rest and Serve Warm
Transfer the sauce to a clean bowl and let it rest for 5 minutes before serving. This resting period allows the flavors to fully develop and the sauce to reach its peak creaminess. The sauce should be silky smooth, with no lumps or graininess, and a rich, cheddar-forward taste that's perfect for dipping or topping.
Serve the sauce warm, either as a dip for fries or as a topping for burgers and sandwiches. The ultra-creamy texture and perfect balance of cheddar flavor will make you wonder how you ever lived without it. Store any leftovers in an airtight container in the refrigerator for up to 5 days, or freeze for up to 3 months. Reheat gently over low heat, stirring frequently to maintain its smooth consistency.
Pro Tips For Making Arby'S Cheddar Cheese Sauce
- Melt Cheese Slowly: Start with the butter and flour on medium-low heat—this sauce will scorch if you rush it. I learned this the hard way after watching a pot of perfectly good cheddar turn into a burnt brick. Keep it moving, but don’t crank the heat.
- Grate Onion Fine: Tiny onion pieces caramelize faster and add sweetness without bitterness. Skip the food processor—just pulse a few times in a mini chopper, or hand-grate it. Big chunks? They’ll turn mushy and muddy the sauce.
- Whisk Like You Mean It: The moment you add the heavy cream, stop stirring and whisk aggressively for 30 seconds. This breaks up the cheese properly and keeps lumps from forming. Lazy stirring = grainy sauce. (Yes, even if you’re impatient like me.)
- Use Real Sharp Cheddar: Pre-shredded cheese has anti-caking agents that make the sauce clump. Buy a block, grate it fresh, and save yourself the cleanup. If you’re in a pinch, pulse pre-shredded in a food processor to break up the clumps—but it won’t taste the same.

Frequently asked questions
Why does my homemade cheddar sauce get grainy?
Graininess happens when cheese melts too quickly or separates from the liquid. The fix? Always melt cheese gradually over low heat and whisk constantly. Remove from heat while adding cheese, then return to heat only after it's fully incorporated. Pre-shredded cheese (with anti-caking agents) is the #1 culprit—always use freshly grated block cheese.
Can I make this sauce without heavy cream?
Yes! Substitute with half-and-half plus 1 extra tablespoon of butter for richness, or use whole milk plus 2 extra tablespoons of butter for a lighter version. For extra decadence, blend 1 cup sour cream with 1 cup milk>—just warm it gently first to prevent curdling. The sauce will be slightly thinner but still delicious.
How do I fix a sauce that's too thick or too thin?
For thick sauce, whisk in 1-2 tablespoons of warm milk or cream until smooth. For thin sauce, simmer uncovered over low heat for 3-5 minutes to reduce liquid. Never boil—this can cause separation. If the sauce breaks, whisk in 1 tablespoon cold butter to re-emulsify. Stir constantly until silky again.
What's the secret to making this sauce restaurant-style?
The restaurant version relies on three key tricks: sharp cheddar cheese (not mild), slow melting over low heat, and a flour slurry (mix 1 tbsp flour with 2 tbsp cold water, whisk into hot sauce). This creates that signature cling without altering flavor. Also, use Diamond Crystal kosher salt—it's less salty than table salt, so you can adjust to taste more precisely.
Can I make this sauce ahead of time?
This sauce actually tastes better the next day as flavors meld. Store in an airtight container in the fridge for up to 5 days. To reheat, warm over low heat and stir in 1 tablespoon milk or cream to restore smoothness. For freezing, cool completely first, then freeze in 1-cup portions for easy thawing. Thaw overnight in the fridge—never microwave directly from frozen.
