Kraft Singles Cheese Sauce Recipe: Smooth Melty Goodness for Dipping

This cheese sauce transforms Kraft Singles into a velvety, smooth dip that clings perfectly to chips, veggies, or pasta. I developed it for quick, reliable results without complicated techniques.

The secret is low heat and constant stirring, which prevents the cheese from separating or becoming grainy. A splash of milk creates the ideal consistency—thick enough to coat but still pourable.

You’ll get a rich, melty sauce with that nostalgic processed cheese flavor, ready in under 10 minutes. It reheats beautifully, making it perfect for parties or meal prep.

Use it for nachos, mac and cheese, or as a grilled cheese upgrade. Here’s how to make it.

Ingredients for Kraft Singles Cheese Sauce

Nine simple ingredients transform into this ultra-smooth, nostalgic cheese sauce in minutes.

The Kraft Singles are non-negotiable here—they melt perfectly without the graininess of natural cheeses. Any grocery store carries them, and the pre-sliced format saves prep time. I grab the full-fat version for that classic, creamy texture. Whole milk is key for the right consistency (low-fat can make it too thin). Organic Valley is my go-to brand if I’m splurging on quality.

No whole milk? Half-and-half at half the quantity works in a pinch (use 1/4 cup instead of 1/2). Want to skip the roux? A cornstarch slurry (1 tsp cornstarch + 1 tbsp cold water) can replace the flour. Butter substitutes like margarine work too, but real butter tastes best. The mustard powder might seem odd, but it’s what gives that signature processed cheese zing—don’t skip it.

Sauce keeps 3-4 days in the fridge when stored in an airtight container. Reheat gently on low heat, stirring constantly. Freezing isn’t ideal (it can separate), but if you must, it’ll last 1 month—just whisk vigorously when reheating.

Step-by-Step Instructions for Kraft Singles Cheese Sauce

This method transforms simple ingredients into a luxuriously smooth sauce perfect for dipping.

Step 1: Create the Roux Base

Melt the 2 tbsp Unsalted Butter in a medium saucepan over medium heat. Watch for the butter to melt completely and just begin to foam—this is your signal it’s ready for the next step.

Whisk in the 1 tbsp All-Purpose Flour immediately. The mixture will thicken into a paste. Keep whisking constantly for 1-2 minutes until the roux turns a pale golden color and smells slightly nutty. This cooks out the raw flour taste and creates the perfect base for your sauce.

Step 2: Gradually Incorporate Milk

Slowly pour in the 0.5 cup Whole Milk, about 1-2 tbsp at a time, while whisking continuously. This gradual addition prevents lumps from forming. The mixture will initially look thin, but it will thicken as you continue to cook and whisk.

After all the milk is incorporated, continue cooking for 2-3 minutes until the mixture thickens enough to coat the back of a spoon. You’ll notice it transforming from a thin liquid to a velvety base. This is when you know the roux has properly thickened the milk.

Step 3: Season and Add Cheese

Reduce the heat to low and stir in the 0.5 tsp Mustard Powder, 0.25 tsp Garlic Powder, 0.25 tsp Onion Powder, 0.25 tsp Salt, and 0.125 tsp Black Pepper. Whisk well to distribute the spices evenly throughout the sauce.

Add the 8 slices Kraft Singles, one at a time, stirring constantly until each slice is completely melted before adding the next. This slow addition ensures an ultra-smooth sauce without any cheese clumps. The sauce will become glossy and perfectly fluid when ready.

Step 4: Adjust and Serve

Once all the Kraft Singles have melted, taste and adjust seasoning if needed. The mustard powder should provide a subtle tang, while the garlic and onion powders add depth. If the sauce is too thick, thin it with a splash of milk, 1 tbsp at a time.

Transfer to a serving bowl immediately. The sauce will thicken slightly as it cools, so serve it warm for the best dipping consistency. It should cascade smoothly off a spoon with a beautiful, creamy texture that clings perfectly to whatever you’re dipping.

Troubleshooting This Recipe

Grainy Texture Fix

If your sauce turns grainy, the cheese likely overheated. Remove from heat immediately and whisk in 1-2 tbsp hot milk until smooth. Low and slow is key—I’ve saved many sauces this way. 💪

Thin or Runny

When the sauce is too thin, create a quick slurry with 1 tsp cornstarch and 1 tbsp cold water. Stir this into the sauce and cook for 1-2 minutes until thickened. Avoid boiling, which can break the emulsion.

Cheese Not Melting

If the Kraft Singles resist melting, switch to a double boiler method. Place your saucepan over a pot of simmering water, ensuring the bottom doesn’t touch the water. This gentle heat coaxes the cheese into a smooth melt.

Lumpy Sauce

Lumps often form from adding milk too quickly. If this happens, strain the sauce through a fine-mesh sieve while warm. Press gently with a spatula to push through any stubborn bits. I keep a sieve handy just for this.

Separated Sauce

If the sauce splits into greasy and liquid parts, whisk in 1 tsp lemon juice or white vinegar. The acid helps re-emulsify the fats and liquids. Stir vigorously until it comes back together.

Over-Salting

Kraft Singles can be salty. If your sauce is too salty, stir in 1-2 tbsp unsalted butter or a splash of milk. These dilute the saltiness without thinning the sauce too much. 💡
