Ingredients for culver's cheese sauce
Six simple ingredients transform into restaurant-quality cheese sauce with that signature velvety swirl.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ½ cup | Cold, cut into small cubes |
| Whole Milk 🥛 | 1 cup | Full-fat preferred for creaminess |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Freshly grated, block preferred |
| Buttermilk 🥛 | ¼ cup | Full-fat for authentic tang |
| Granulated Garlic Powder 🧄 | ½ tsp | For subtle depth of flavor |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly cracked for best flavor |
| Diamond Crystal Kosher Salt 🧂 | ¼ tsp | Adjust to taste after tasting |
| Cornstarch 🌾 | 1 tbsp | Only if sauce needs thickening |
The cheese is non-negotiable—sharp white cheddar from a block (not pre-shredded) gives that authentic Culver's flavor. I grab mine at Whole Foods or Penzeys for the best quality, but any good grocery store carries it. The buttermilk is your secret weapon—full-fat makes all the difference. Skip the low-fat version (trust me on this). For the butter, unsalted is key since we're controlling the salt ourselves. If you're in a pinch, European-style butter adds extra richness, but regular unsalted works perfectly fine.
No buttermilk? Substitute with 1/4 cup milk plus 1 tbsp lemon juice—it won't be identical but gets you close. Short on sharp cheddar? Colby Jack or extra-sharp cheddar work in a bind, though the flavor will shift slightly. The garlic powder and pepper are subtle but essential—don't skip them. For extra tang, add 1/2 tsp white vinegar to the milk. And if your sauce gets too thin? Cornstarch slurry (1 tbsp cornstarch + 1 tbsp cold water) fixes it instantly. Pro tip: Toast the cornstarch in the dry pan for 30 seconds before mixing—it removes any raw taste.
This sauce reheats beautifully—just whisk in a splash of milk if it thickens too much. Keeps 5 days in the fridge, 3 months frozen. For freezing, cool completely first, then portion into ice cube trays before transferring to a container. When reheating, warm over low heat while stirring constantly to prevent separation. I always make a double batch—one for immediate use and one to freeze for lazy weeknights. The leftovers taste even better the next day as flavors meld.

Step-by-step instructions for Culver's cheese sauce
Here's how to recreate that iconic, ultra-smooth cheese sauce with the perfect balance of tang and richness.
Melt the Butter and Milk Over Gentle Heat
In a medium saucepan, combine the 0.5 cup unsalted butter (cut into small cubes) with the 1 cup whole milk. Place the pan over medium-low heat and let it warm gently, stirring occasionally with a silicone spatula. You want the butter to melt completely without browning—this ensures a clean, creamy base. The milk should heat just enough to warm the butter but not boil. I like to watch for tiny bubbles forming around the edges of the pan; that's your signal the mixture is ready for the next step.
Here's the thing—if you rush this step and let the milk get too hot, you'll end up with a grainy sauce later. The buttermilk and cheese need a gentle environment to emulsify properly. Keep the heat at medium-low and maintain a slow, even simmer throughout this process. If you see the milk starting to bubble vigorously, reduce the heat immediately to prevent scorching.
Add Cheese and Seasonings
Once the butter and milk mixture is smooth and warm (but not boiling), reduce the heat to low and begin adding the 2 cups freshly grated sharp white cheddar cheese. I like to add it in small handfuls, stirring constantly with the spatula to prevent clumping. The cheese should melt gradually, creating a thick, velvety texture. If you notice any lumps forming, press them against the side of the pan with the spatula—the residual heat will help them melt.
While the cheese melts, sprinkle in the 0.5 teaspoon granulated garlic powder, 0.25 teaspoon ground black pepper, and 0.25 teaspoon diamond crystal kosher salt. Stir these seasonings into the mixture until fully dissolved. The garlic powder adds a subtle depth that's key to that authentic Culver's flavor, while the pepper and salt balance the richness. Taste the sauce at this stage—it should be tangy and slightly sharp, but not overly salty. You can always adjust the salt later if needed.
Incorporate the Buttermilk for Tang and Thickness
Now for the secret ingredient—the 0.25 cup buttermilk. Slowly pour it into the cheese mixture while stirring continuously. The buttermilk introduces that signature tang that sets Culver's cheese sauce apart from others. You'll notice the sauce thicken slightly as it reacts with the melted cheese. If the sauce becomes too thick at this point, you can thin it out with a splash of warm milk, but we'll address thickening more precisely in the next step.
This is where the magic happens—the buttermilk not only adds tang but also helps create that ultra-smooth, almost custard-like texture. Keep stirring gently over the low heat for 2-3 minutes to let the flavors meld. The sauce should now be thick and glossy, with a slight sheen that indicates it's ready for the final touch. If you're making this for a crowd, now's the time to taste and adjust the seasoning—another pinch of salt or a dash of pepper can elevate the flavor.
Thicken to Perfect Consistency (If Needed)
If the sauce isn't thick enough for your liking, whisk together the 1 tablespoon cornstarch with 1 tablespoon of the warm milk in a small bowl. Slowly drizzle this mixture back into the saucepan while stirring constantly. The cornstarch will thicken the sauce almost immediately, giving it that signature velvety swirl consistency. Keep stirring for 1-2 minutes until the sauce reaches your desired thickness—it should coat the back of a spoon but still be pourable.
Here's a pro tip: If you add the cornstarch too quickly, you risk creating lumps. That's why it's important to whisk it with a little milk first and add it gradually. The sauce should be smooth, glossy, and hold its shape when drizzled. If it's still too thin, repeat the process with another ½ teaspoon cornstarch mixed with ½ teaspoon milk. The goal is a sauce that's thick enough to cling to fries or hot dogs but still has that signature swirl when stirred.
Serve Immediately for Maximum Creaminess
Once the sauce reaches the perfect consistency, remove it from the heat and transfer it to a serving dish or slow cooker to keep it warm. The sauce will continue to thicken slightly as it cools, so it's best served immediately while it's still hot and ultra-smooth. If you're serving it over fries or hot dogs, stir in a little extra milk or butter to loosen it up just before serving—this ensures it coats everything beautifully.
For the full Culver's experience, serve the cheese sauce in a slow cooker on the "warm" setting. This keeps it creamy and ready to drizzle over your favorite dishes all evening. The sauce should be rich, tangy, and velvety, with a perfect balance of sharp cheddar and buttermilk tang. If you've followed these steps carefully, you'll have a cheese sauce that's indistinguishable from the one you'd get at Culver's—smooth, swirly, and utterly addictive.
Pro Tips For Making Culver'S Cheese Sauce
- Melt Cheese Slowly: I learned this the hard way—dumping shredded cheddar into hot liquid makes it clump like sad cottage cheese. Instead, lower the heat to medium-low once the milk and butter are simmering, then whisk in the cheese a handful at a time. Let each addition melt completely before adding more, or you’ll end up with a gloppy mess instead of that perfect, velvety texture.
- Use Buttermilk Last: The buttermilk’s job is to balance the richness, not cook. Add it off the heat, just before serving, and whisk it in until the sauce is silky. Cooking it too long turns it tangy and curdles the whole thing—trust me, I’ve ruined a batch by being impatient.
- Shred Cheese Coarse: Skip the food processor for this one. Sharp white cheddar should be shredded by hand into uneven chunks—think restaurant-style, not powdery. The bigger the shreds, the fewer lumps you’ll fight later, and the sauce will have that signature, melt-in-your-mouth mouthfeel.
- Keep Butter Warm: Cold butter in hot milk? That’s a recipe for greasy separation. Melt the butter first over low heat until it’s just liquid but not browned, then pour it into the warm milk. This keeps the sauce smooth from the start—no scrambling to fix broken emulsions later.

Frequently asked questions
Why does this cheese sauce have a tangy flavor?
The signature tang comes from the 0.25 cup buttermilk—it's the secret ingredient that mimics Culver's signature taste. Buttermilk adds acidity that balances the richness of the cheese, creating that perfect creamy-tangy combo. Without it, the sauce would taste flat and overly cheesy.
Can I make this cheese sauce without buttermilk?
Yes! Substitute with 1/4 cup milk + 1 tablespoon lemon juice for a similar tang. However, buttermilk creates a smoother texture and deeper flavor. If you're short on time, this works in a pinch, but the authentic version uses buttermilk for that restaurant-quality taste.
How do I fix a cheese sauce that's too thick or too thin?
For too thick: Thin with 1 tablespoon warm milk at a time while stirring. For too thin: Mix 1 tablespoon cornstarch + 1 tablespoon cold milk into a slurry, then whisk into the sauce. Heat gently until thickened. Always adjust gradually to avoid lumps.
What's the best way to reheat leftover cheese sauce?
Gently warm over low heat while stirring constantly to prevent separation. If it thickens too much, whisk in 1-2 tablespoons milk until smooth. Never microwave—it can make the sauce grainy. The sauce reheats best when warmed slowly on the stove.
Can I use this sauce for sweet dishes like pancakes?
The sharp cheddar pairs surprisingly well with sweet flavors. Drizzle over pancakes, waffles, or fruit compote for a sweet-and-savory twist. For extra decadence, mix in 1 tablespoon honey or maple syrup to balance the tang. It’s a breakfast game-changer!
