Ingredients for culver's cheese sauce copycat

Eight simple ingredients transform into that iconic creamy sauce you crave.

The cheeses are everything here. Sharp cheddar gives the tang, while American cheese delivers that signature stretch—don't skip either. Grab the block cheddar for best results (pre-shredded has anti-caking agents that ruin texture). Kraft Singles or Boar's Head American cheese slices work perfectly. For the butter, Land O'Lakes or Plugrah are my go-tos—they melt smoothly without burning. The milk? Whole milk is non-negotiable for that ultra-creamy finish. Skim or 2% will give you a thinner, less luxurious sauce.

No sharp cheddar? Monterey Jack or Colby will work in a pinch, but the flavor won't be identical. Out of American cheese? Muenster shredded gets you close, though it's slightly stronger. The cornstarch is your secret weapon—it's what makes this sauce silky instead of grainy. Arrowhead brand is my preferred choice. For the sugar, white granulated works, but brown sugar adds a subtle caramel note if you're feeling adventurous. The mustard powder is what gives it that faint tang—don't omit it, but don't overdo it either.

This sauce reheats beautifully—just add a splash of milk to loosen it up. Keeps for 5-7 days in the fridge, fully covered. For longer storage, freeze in ice cube trays—perfect for single servings. Thicken too much? Stir in a teaspoon of milk at a time. Too thin? A pinch more cornstarch mixed with cold water works wonders. Make a double batch—you'll want leftovers for fries, burgers, or mac and cheese.

Step-by-step instructions for Culver's copycat cheese sauce

Here's how to make that iconic, velvety cheese sauce without a single burn or clump.

In a medium saucepan over medium-low heat, add the 0.5 cup unsalted butter and let it melt completely, stirring occasionally. Once melted, reduce heat to low and add the 1.5 cups shredded sharp cheddar cheese and 1.5 cups shredded American cheese slices all at once.

Stir constantly with a wooden spoon or silicone spatula, breaking up any large cheese clumps as they melt. You'll know it's ready when the cheese is fully melted and the mixture is smooth—this should take about 3-4 minutes. If you see any browned bits forming, immediately reduce the heat to lowest setting to prevent burning. The key here is patience; rushing this step will ruin your sauce.

In a small bowl, whisk together the 1.5 cups whole milk and 1 tbsp cornstarch until completely dissolved. This mixture is called a slurry, and it's what gives the sauce that signature ultra-smooth texture. Pour the milk mixture into the cheese pan slowly, whisking constantly to prevent lumps from forming.

Increase the heat to medium-low and continue stirring for 3-4 minutes until the sauce begins to thicken. You'll see it transform from a thin liquid to a glossy, creamy consistency. If the sauce starts to bubble vigorously, reduce the heat immediately—you want a gentle simmer, not a boil. This is where the magic happens, so don't walk away.

Once the sauce has thickened, add the 1 tbsp granulated sugar, 0.5 tsp mustard powder, 0.5 tsp salt, and 0.25 tsp black pepper. Stir well to combine all the seasonings evenly throughout the sauce. Taste and adjust the seasoning if needed—you might want to add a pinch more salt or a dash of pepper to match your preference.

Continue simmering on low heat for another 2-3 minutes, stirring occasionally, until the sauce reaches your desired consistency. It should coat the back of a spoon smoothly without being too thick. If it's still too thin, you can thicken it further by mixing 1 tsp cornstarch with 1 tbsp cold milk and whisking it in. For the best results, keep the sauce warm in the pot until ready to serve.

Transfer the cheese sauce to a clean saucepan or slow cooker set to warm if you're not using it immediately. This keeps the sauce perfectly smooth and ready to pour over fries, burgers, or hot dogs. The sauce will thicken slightly as it cools, so if you're serving it right away, you might want to thin it with a splash of warm milk if needed.

For the ultimate copycat experience, serve this cheese sauce piping hot over Culver's famous onion rings, fries, or a loaded burger. The secret to this sauce is in the slow, steady cooking process—no rushing, no high heat, just patience and attention to detail. You'll be amazed at how close you can get to the real deal with just these simple ingredients.

Creative variations of this dish

Spicy Kick Option

For heat lovers, stir in ½ tsp smoked paprika and ¼ tsp cayenne pepper with the mustard powder. This adds a subtle smoky heat that mimics Culver's occasional spicy sauce variations.

I like to add it gradually—taste first, then adjust. For extra kick, a dash of hot sauce (like Frank's RedHot) at the end works perfectly. 🌶️

Herb-Infused Twist

Swap the mustard powder for ½ tsp onion powder and ¼ tsp garlic powder for a savory depth. Add 1 tsp fresh chives or 1 tbsp chopped parsley at the very end for a bright, herby finish.

This version pairs beautifully with loaded baked potatoes or grilled chicken. I find Penzeys brand spices work best for consistent flavor.

Extra Creamy Version

Replace half the milk with ½ cup heavy cream for a richer, more decadent sauce. This version is ideal for dipping—think onion rings or mozzarella sticks. For even more indulgence, stir in 2 oz cream cheese with the butter at the start.

The result? A sauce so smooth it feels like velvet. Just watch your portions—this one's a calorie bomb! 🧈

Dairy-Free Adaptation

Use 1.5 cups unsweetened almond milk instead of whole milk and substitute ½ cup nutritional yeast for the American cheese. For the cheddar, opt for dairy-free sharp cheddar shreds (like Violife brand).

Add 1 tbsp olive oil to compensate for the lack of butter. The texture won't be identical, but it's surprisingly close and works well for vegan diets. 🌱

Slow Cooker Method

Combine all ingredients in your slow cooker and cook on low for 2-3 hours, stirring occasionally. This hands-off method is perfect for meal prep. For extra creaminess, add ¼ cup sour cream at the end.

The slow cooker keeps the sauce warm and prevents burning. I use this method when making a big batch for parties—just reheat and serve! ⏰

Breakfast-Style Upgrade

Add a pinch of cinnamon and ½ tsp vanilla extract to transform this sauce into a breakfast sensation. Drizzle over pancakes, waffles, or French toast for a sweet-and-savory twist. For extra indulgence, fold in 2 tbsp maple syrup at the end. This version is a game-changer for weekend brunch. 🍯
