Ingredients for campbell's cheese sauce
Nine simple pantry staples transform into velvety swirls perfect for mac and cheese or baked potatoes.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ½ cup | Cold cubes for roux, full-fat for creaminess |
| All-Purpose Flour 🌾 | ½ cup | White flour preferred for smoothness |
| Campbell's Cream of Mushroom Soup 🍄 | 1 can | Condensed, 10.5 oz can |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Shredded, 4 oz block preferred |
| Milk 🥛 | ½ cup | Whole milk for richness |
| Medium Cheddar Cheese 🧀 | ½ cup | Shredded, adds balanced flavor |
| Salt 🧂 | ½ tsp | Kosher salt for even seasoning |
| Ground Black Pepper 🌶️ | ¼ tsp | Freshly ground for best flavor |
| Garlic Powder 🧄 | ¼ tsp | Adds subtle depth (optional) |
| Mustard Powder 🌶️ | ¼ tsp | Brightens flavor profile |
The butter and flour are your secret weapons here. Use cold butter cubes—they melt slowly for a perfect roux that won’t burn. I grab the Land O'Lakes unsalted sticks from any grocery store, but any full-fat butter works. For flour, Bob's Red Mill all-purpose is my go-to because it blends smoothly without lumps. The Campbell’s soup? Grab the cream of mushroom variety—it adds that subtle earthiness that makes this sauce sing. If you're using pre-shredded cheese, shake the bag first—it clumps like crazy otherwise. I always buy a 4 oz block of sharp cheddar and shred it myself for the best texture.
No Campbell’s soup? Substitute 1 cup whole milk + 2 tbsp cornstarch for thickening. Pre-shredded cheese giving you grief? Use a food processor to break up clumps before adding. Want to kick it up? Swap half the cheddar for Gruyère or smoked Gouda—game changer. The mustard powder might sound weird, but it brightens the sauce and balances the richness. If you don’t have it, just skip it. Milk too watery? Use half-and-half instead—it’s richer and adds that perfect creaminess without curdling. And for heaven’s sake, don’t rush the roux. Cook it low and slow until it’s golden but not browned—this is where the magic happens.
This sauce reheats like a dream—just stir in a splash of milk if it gets too thick. Keeps 4-5 days in the fridge, 3 months frozen. I make a double batch every time because it disappears fast. For freezing, cool it completely first, then portion into ice cube trays—perfect for single servings later. The roux base? Make it ahead and store in the fridge for up to 3 days—just add the rest when you're ready to use it. Trust me, this shortcut saves time on busy nights.

Step-by-step instructions for Campbell's creamy cheese sauce
Here's how to make this ultra-smooth sauce that's perfect for mac and cheese, baked potatoes, or dipping bread.
Melt the Butter and Whisk in Flour
In a medium saucepan over medium heat, melt the 0.5 cup unsalted butter until it's completely liquid and foamy. I like to watch for those little bubbles forming around the edges—that's your signal it's ready. Immediately reduce the heat to low and whisk in the 0.5 cup all-purpose flour all at once.
Keep whisking constantly for 1-2 minutes until the mixture turns a pale golden color and smells nutty. This is your roux, and it's the secret to that velvety texture. If you see any lumps forming, just keep whisking—those will disappear as the mixture cooks. This step is crucial because it creates the base that will thicken your sauce perfectly.
Cook the Roux Until Smooth
Continue cooking the roux for another 2-3 minutes, whisking constantly, until it's smooth and has a slightly thickened consistency. You'll notice it starts to bubble more vigorously—this is normal and means it's working. The key here is patience; don't rush this step or your sauce might end up grainy.
I like to keep the heat at low-medium so it cooks gently. If it starts to darken too much, reduce the heat slightly. You're aiming for a color between pale cream and light tan. This cooked roux will form the rich, creamy foundation for your cheese sauce, so take your time getting it just right.
Gradually Add the Milk and Cheese
Slowly pour in the 0.5 cup milk while whisking continuously to prevent lumps from forming. Add it gradually—about 1 tablespoon at a time—and keep whisking until each addition is fully incorporated. Once all the milk is added, stir in the 1.5 cups sharp cheddar cheese and 0.5 cup medium cheddar cheese.
Here's where it gets exciting—the cheese should start to melt and create a thick, creamy mixture almost immediately. If you notice any cheese clumps, just keep stirring with a wooden spoon until everything smooths out. The heat from the roux will help melt the cheese completely. This is the moment that matters: you want that perfect balance of cheesy richness without any graininess.
Incorporate the Cream of Mushroom and Seasonings
Stir in the 1 can Campbell's cream of mushroom soup and bring the mixture to a gentle simmer over medium-low heat. Keep stirring occasionally as it heats through. This is where that subtle mushroom flavor comes into play, adding depth to your cheese sauce. Once it's simmering gently, reduce the heat to low and stir in the 0.5 teaspoon salt, 0.25 teaspoon ground black pepper, 0.25 teaspoon garlic powder, and 0.25 teaspoon mustard powder.
Let the sauce simmer for another 3-5 minutes, stirring occasionally, until it's completely smooth and reaches your desired consistency. You'll know it's ready when it coats the back of a spoon and has that beautiful, velvety sheen. The mustard powder adds a nice tang that brightens up the richness, while the garlic powder gives it just a hint of savory depth.
Adjust Consistency and Serve Warm
If your sauce is too thick, you can loosen it with a splash of warm milk or water, 1 tablespoon at a time, until it reaches that perfect pouring consistency. For a richer sauce, you can even add a bit more milk and let it simmer a bit longer. Taste and adjust the seasoning if needed—sometimes you might need a bit more salt or pepper to balance the flavors.
This cheese sauce is best served warm, so keep it on low heat or transfer it to a heatproof serving dish. It's perfect for mac and cheese, baked potatoes, or even as a dip for crusty bread. The combination of sharp and medium cheddar gives it a complex flavor profile that's both creamy and satisfying. Don't be afraid to get creative with it—this sauce is incredibly versatile!
Pro Tips For Making Campbell'S Cheese Sauce
- Whisk Like You Mean It: The roux is where flavor hides—or gets ruined. Use a wire whisk and keep the heat medium-low while stirring constantly for 2–3 minutes. I learned this the hard way—lumpy roux means grainy sauce, and no one wants that in their mac and cheese.
- Grate Cheese Fresh: Pre-shredded cheddar has anti-caking agents that turn your sauce weirdly grainy. Use a box grater and shred the cheese yourself—it melts smoother and tastes sharper. (Yes, it takes 30 seconds. No, you can’t skip it.)
- Warm the Milk First: Cold milk in hot roux = instant lumps. Heat the milk in the microwave for 30 seconds or warm it in a saucepan before adding it to the butter-flour mix. Trust me, your sauce will thank you.
- Simmer, Don’t Boil: Once you add the soup and cheese, keep the heat low and let it bubble gently. Boiling it turns the sauce thin and watery—like you’re making glue, not comfort food. A slow simmer keeps it thick and velvety.
Serving suggestions for campbell's cheese sauce
Mac and Cheese Masterpiece
Transform this sauce into the ultimate mac and cheese by tossing it with al dente cavatappi or elbow pasta. I use De Cecco pasta because it holds up perfectly to the rich sauce.
For extra decadence, add crispy bacon bits or crumbled pancetta on top before baking. Bake at 375°F for 15-20 minutes until bubbly and golden. 🧀
Loaded Baked Potatoes
This sauce takes baked potatoes to the next level. Slice open a russet potato (baked for 60-75 minutes at 400°F), spoon on the warm cheese sauce, and top with crispy bacon, green onions, and a sprinkle of paprika.
The sauce clings beautifully, creating a cozy, creamy blanket over every bite. 🥔
Cheesy Bread Dip
Turn this sauce into a crowd-pleasing dip by serving it warm in a slow cooker or oven-safe dish. Toss in tortilla chips or fresh bread cubes for dipping.
For extra flair, add a pinch of smoked paprika or chili powder to the sauce before serving. It’s perfect for game day or movie nights! 🍞
Vegetable Topper
Use this sauce to elevate roasted vegetables like broccoli, cauliflower, or Brussels sprouts. Roast the veggies at 425°F for 20-25 minutes, then drizzle with the cheese sauce and broil for 2-3 minutes to create a golden, gooey finish. The sauce adds richness without overpowering the veggies. 🥦
Grilled Cheese Upgrade
Take your grilled cheese sandwich to gourmet status by spreading this sauce on sourdough or brioche bread before assembling. Add a slice of Gruyère or provolone for extra meltiness.
Toast in a butter-coated pan over medium heat until crispy and golden. The sauce oozes out with every bite—pure comfort food magic. 🥪
Dessert Twist
For a sweet surprise, stir in ½ cup powdered sugar and 1 tsp vanilla extract to the cooled sauce. Drizzle over warm apple slices, cinnamon toast, or chocolate chip cookies for a creamy, cheesy dessert. It’s a fun way to repurpose leftovers into something unexpected! 🍎

Frequently asked questions
Can I make this sauce without Campbell's soup?
For a homemade version, mix 1 cup whole milk with 2 tablespoons cornstarch to replace the soup. Heat the milk until warm, whisk in the cornstarch, then let it thicken for 2-3 minutes before adding to your roux. The sauce will still be creamy, though the subtle mushroom flavor will be missing.
Why did my cheese sauce get grainy?
Graininess usually happens when cheese doesn't melt completely or the sauce cooks too fast. Always use low heat and stir constantly while adding cheese. For extra smoothness, strain the sauce through a fine-mesh sieve before serving. Pre-shredded cheese often clumps—grate your own or pulse it in a food processor first.
How do I store and reheat leftovers?
Store in an airtight container in the fridge for 4-5 days or freeze for 3 months. To reheat, warm over low heat on the stove, stirring often. If it thickens too much, add 1 tablespoon milk at a time until smooth. Never microwave directly from the fridge—it can separate.
Can I use different cheeses in this recipe?
Yes! Swap cheddar for Gruyère, Monterey Jack, or smoked Gouda for unique flavors. For extra richness, add ½ cup cream cheese at the end. Just remember—milder cheeses need more seasoning. Always shred your own for best texture, or pulse pre-shredded cheese to break up clumps.
Is this sauce kid-friendly?
The mild cheddar and creamy texture make it perfect for picky eaters. For extra appeal, serve it with chicken nuggets, veggie sticks, or crackers. You can even add a pinch of cayenne pepper for a subtle kick—kids might not notice! Always let it cool slightly before serving to avoid burns.
