Sauces & Condiments
Creating a Campbell's-style cheese sauce that's velvety smooth and lump-free is easier than you think—and this recipe delivers exactly that. The secret lies in precise timing and a few simple ingredients that transform ordinary dairy into a rich, creamy sauce perfect for mac and cheese, baked potatoes, or dipping.
I’ve refined this method over years of testing, ensuring every batch turns out perfectly every time.
This recipe relies on just five key ingredients—milk, butter, flour, sharp cheddar, and a touch of mustard powder—for depth. The process is straightforward: melt butter, whisk in flour to form a roux, then gradually add milk while stirring constantly to avoid lumps.
The cheese melts into the warm mixture, creating a sauce that’s impossibly smooth and rich. No fancy equipment or complicated steps—just patience and attention to detail.
What you’ll end up with is a creamy, velvety cheese sauce that coats everything beautifully, whether poured over hot pasta, spooned onto baked potatoes, or used as a dipping sauce for veggies.

This sauce keeps well in the refrigerator for up to five days, making it perfect for meal prep. Double the batch and store leftovers for quick, creamy meals all week. Let’s get started—your taste buds will thank you.
Ingredients for campbell's cheese sauce
Five simple ingredients transform into velvety cheese sauce perfect for dipping or drizzling.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ½ cup | Cold, cut into small cubes |
| All-Purpose Flour 🌾 | ¼ cup | Sifted for smooth texture |
| Whole Milk 🥛 | 2 cups | Room temperature preferred |
| Sharp Cheddar Cheese 🧀 | 2 cups | Shredded, block preferred |
| Mustard Powder 🌶️ | ½ tsp | For depth of flavor |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ¼ tsp | Optional, for subtle kick |
The butter and flour are your secret weapons here—cold butter creates tiny flour pockets that melt smoothly, while sifting the flour prevents clumps. Grab unsalted butter from the store (the kind in the tub, not sticks) for better control. Sharp cheddar is non-negotiable—Kraft singles won’t cut it. Look for a wedge at the grocery store deli counter or pre-shredded from a block (the kind in the green bag). Mustard powder adds that signature depth Campbell’s gets right—don’t skip it. For the milk, whole milk gives the best creaminess, but 2% works in a pinch.
No sharp cheddar? Parmesan or Monterey Jack can stretch it, but you’ll lose that tangy bite. Out of mustard powder? Dijon mustard at half the amount works too—just whisk it into the milk first. The flour can be swapped for cornstarch at one-third the amount if you’re in a hurry, but the sauce won’t be quite as rich. For extra flavor, add a pinch of smoked paprika or a dash of hot sauce. Pro tip: if your sauce gets too thick, just whisk in a splash of warm milk—no need to start over.
This sauce reheats beautifully—just stir in a splash of milk if it thickens up. Keeps in the fridge for 5 days, covered tightly. For meal prep, portion into small jars or containers so you can grab exactly what you need. Freezes for 3 months if you want to make a big batch. The best part? It tastes even better the second day as all the flavors meld together. Trust me, you’ll make this again—and again.

Step-by-step instructions for creamy cheese sauce
Here's how to make a perfectly smooth, velvety cheese sauce every time without lumps or guesswork.
Melt the Butter and Whisk in the Flour
Cut the 0.5 cup unsalted butter into small cubes and place them in a medium saucepan over medium heat. Let them melt completely, then reduce the heat to medium-low. This lower heat prevents burning while ensuring the butter melts evenly.
Once the butter has melted, immediately sprinkle the 0.25 cup all-purpose flour over the top. Use a whisk to gently stir the flour into the butter, creating a smooth paste. This step is crucial—it forms the roux that will thicken your sauce. Keep whisking for 1-2 minutes until the mixture turns a light golden color and smells nutty. If it darkens too quickly, reduce the heat slightly.
Cook the Roux Until Smooth and Bubbly
Continue whisking the roux for 2-3 minutes until it becomes a thick, paste-like consistency. You'll notice the mixture will bubble gently and pull away from the sides of the pan. This indicates the raw flour taste has cooked off, and your sauce is ready for the next step.
Here's the thing—don't walk away. If the roux starts to brown too much, it'll add a bitter taste to your sauce. You want it to be smooth, pale golden, and fully combined. If it gets too dark, start over with fresh butter and flour.
Gradually Add the Milk for a Silky Texture
Slowly pour in the 2 cups whole milk, whisking constantly to prevent lumps from forming. I like to add it in a thin, steady stream while whisking vigorously. Once all the milk is incorporated, increase the heat to medium-low and let the mixture simmer gently for 3-4 minutes.
You'll see the sauce thicken noticeably as it cooks. If it gets too thick too quickly, add a splash of milk to loosen it up. The goal is a smooth, creamy consistency that coats the back of a spoon. This gradual addition of milk is what keeps your sauce lump-free and velvety.
Incorporate the Cheese and Seasonings
Reduce the heat to low and begin adding the 2 cups sharp cheddar cheese in small increments. Stir constantly to ensure the cheese melts smoothly into the sauce. If you add it all at once, you risk creating clumps that are nearly impossible to fix. Once all the cheese is incorporated, stir in the 0.5 tsp mustard powder, 0.5 tsp salt, 0.25 tsp black pepper, and 0.25 tsp garlic powder.
Let the sauce simmer gently for another 2-3 minutes, stirring occasionally. You're looking for a completely smooth texture with no visible cheese particles. If you see any lumps, strain the sauce through a fine-mesh sieve for a perfectly polished finish. This step ensures your cheese sauce is creamy, flavorful, and ready to use.
Adjust Consistency and Serve Warm
Taste your sauce and adjust the seasoning if needed. If it's too thick, whisk in a splash of milk until it reaches your desired consistency. For a richer flavor, you can add a pat of butter and stir until melted. The sauce should be smooth, creamy, and ready to drizzle over mac and cheese, broccoli, or any dish that calls for a cheesy touch.
Keep the sauce warm over low heat, stirring occasionally to prevent it from separating. If you're not using it immediately, transfer it to a clean jar or container and store it in the refrigerator for up to 5 days. When reheating, stir gently over low heat until smooth and creamy again. This sauce is versatile, delicious, and perfect for any cheesy craving!
Pro Tips For Making Campbell'S Cheese Sauce
- Whisk the roux fast: Get that butter-flour mix bubbling in under 2 minutes on medium heat—any longer and you’ll taste raw flour. I learned this the hard way when my sauce turned chalky instead of creamy.
- Shred cheese aggressively: Use a box grater or food processor for sharp cheddar, not the blocky chunks from a bag. The finer the shreds, the smoother the sauce—no one wants chewy bits in their mac and cheese.
- Temper the milk slowly: Pour the milk in a thin, steady stream while whisking constantly. Dumping it all at once? You’ll end up with lumps, and no amount of whisking later will fix it.
- Finish with mustard last: Stir in the mustard powder after the sauce is off heat—it burns fast. A pinch (½ tsp) is enough; too much makes it taste like a condiment, not a sauce.

Mac and Cheese Perfection
This cheese sauce transforms ordinary mac and cheese into a restaurant-worthy dish. Cook 12 ounces elbow macaroni according to package instructions, then drain and return to the pot. Stir in 1.5 cups of the cheese sauce until fully coated.
For extra decadence, top with breadcrumbs and extra cheese, then broil for 2-3 minutes until golden. 🧀
Baked Potato Topping
Baked potatoes become a gourmet side when smothered in this sauce. Cut open 4 large russet potatoes (baked until tender), then spoon ½ cup cheese sauce over each.
Add a sprinkle of chives and a dash of hot sauce for a spicy kick. The sauce clings beautifully, making every bite rich and creamy.
Dipping Sauce Magic
Turn this sauce into the ultimate dipping companion. Warm it slightly, then serve with crudité trays (carrots, celery, bell peppers), soft pretzel bites, or even mozzarella sticks.
The velvety texture pairs perfectly with crispy, salty, or crunchy foods. For extra flair, add a pinch of paprika or smoked salt to the sauce before serving.

Frequently asked questions
Why does my cheese sauce turn out lumpy?
Lumps happen when cheese or flour isn't fully incorporated. Always whisk constantly when adding milk to the roux, and stir gently as you melt the cheese. For extra smoothness, strain through a fine-mesh sieve after cooking. The key is patience—don't rush the process!
Can I make this sauce without flour?
Yes! Swap the 0.25 cup flour with 2 tablespoons cornstarch mixed with 1 tablespoon cold water. Whisk this slurry into the butter first, then proceed as directed. The sauce will be slightly thinner but still creamy. For a richer texture, use whole milk instead of 2%.
How do I make this sauce spicier?
Add ½ teaspoon cayenne pepper or 1 teaspoon hot sauce when stirring in the seasonings. For depth, mix ½ teaspoon smoked paprika with the mustard powder before adding to the sauce. For heat lovers, try ½ teaspoon chipotle powder—it adds smoky spice without overpowering.
Can I use powdered milk instead of liquid milk?
Replace the 2 cups whole milk with ½ cup powdered milk mixed with 1½ cups water. The texture will be slightly thicker, so adjust with extra milk if needed. For creaminess, add 1 tablespoon heavy cream to the finished sauce. This works great for meal prep when liquid milk isn't convenient.
What if my sauce separates when reheating?
Stir in 1-2 tablespoons cold water while reheating over low heat. The sauce should smooth out as it warms. For extra insurance, whisk in ½ teaspoon cornstarch mixed with 1 teaspoon water** until fully combined. Never microwave—it causes separation. Always reheat gently on the stovetop.
