Sauces & Condiments
This powdered cheese sauce recipe transforms mac and cheese night from messy to magical with just a splash of milk and a sprinkle of powder. After years of testing, I've perfected a blend that dissolves smoothly into a creamy, velvety sauce every time—no lumps, no stress.
My grandmother used to make something similar, though her version was always measured by feel rather than precision.
The secret lies in the right balance of dehydrated cheese, cornstarch, and a touch of anti-caking agents like powdered milk. This version stays shelf-stable for months, so you can keep a batch on hand for quick weeknight dinners.
The powder dissolves instantly in hot milk or water, creating a sauce that's richer than boxed mixes but with none of the fuss.
What you'll end up with is a foolproof sauce that clings to pasta perfectly, melts over baked potatoes, or elevates grilled cheese to restaurant-quality levels. The texture is smooth and luxurious, with a depth of flavor that comes from real cheese—not powdered shortcuts.
It's the kind of recipe that makes comfort food feel effortless.
Scalable for small batches or large gatherings, this sauce keeps beautifully in airtight containers. Add garlic powder, smoked paprika, or herbs for customizable flavors—just stir before mixing. Here's how to make it, step by step.
Ingredients for powdered cheese sauce
Nine simple ingredients blend into creamy magic that dissolves instantly in hot milk.
| Ingredient | Amount | Notes |
|---|---|---|
| Shredded Sharp Cheddar Cheese 🧀 | 2 cups | Aged 6+ months for best flavor |
| Shredded Monterey Jack Cheese 🧀 | 1 cup | Mild for balanced flavor profile |
| Powdered Milk 🥛 | ½ cup | Non-fat, for anti-caking |
| Cornstarch 🌾 | ¼ cup | For ultra-smooth texture |
| Non-Fat Dry Milk Powder 🥛 | ¼ cup | Same as powdered milk |
| Granulated Garlic Powder 🧄 | 1 tbsp | For subtle depth of flavor |
| Onion Powder 🧅 | 1 tsp | Mild aromatic base |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Xanthan Gum 🧪 | ¼ tsp | Prevents clumping (optional) |
The cheeses are everything here. Sharp cheddar gives that tangy kick while Monterey Jack keeps it smooth. Grab pre-shredded from Trader Joe's or Kroger—the bags labeled 'freshly shredded' melt better than the pre-shredded kind. For the powdered milk, Nestle or Great Value brands work perfectly. The cornstarch is non-negotiable—it's what makes this sauce silky instead of grainy. I always double-check the expiration dates on spices because stale garlic powder ruins everything. Penzeys or the bulk bins at Whole Foods are my go-tos for fresh spices.
No powdered milk? Non-fat dry milk powder works exactly the same. Skip the xanthan gum if you can't find it—it's just a clump-preventer. Want extra richness? Add 1/4 cup powdered Parmesan to the mix. The cheeses can be swapped: Colby Jack instead of Monterey Jack or Pepper Jack for heat. Just keep the ratio 2:1 cheddar to other cheese. For a smoky version, stir in 1/2 tsp smoked paprika before mixing. And if you're making this for a crowd, double the batch—it keeps forever.
Store the powder in an airtight container with a silicone desiccant packet to absorb moisture. Keeps for up to 6 months in a cool, dark pantry. For extra shelf life, freeze portions in 1/4 cup measures—just scoop and mix when needed. The sauce itself? 3-4 days in the fridge once mixed, or freeze for 3 months. I always label my containers with the date so I don't accidentally use expired powder.

Step-by-step instructions for powdered cheese sauce
Here's how to create velvety, lump-free cheese sauce that's perfect for mac and cheese.
Whisk Dry Ingredients Together
In a medium bowl, combine the 2 cups shredded sharp cheddar cheese, 1 cup shredded Monterey Jack cheese, 0.5 cup powdered milk, 0.25 cup cornstarch, 0.25 cup non-fat dry milk powder, 1 tbsp granulated garlic powder, 1 tsp onion powder, 1.5 tsp salt, and 0.5 tsp ground black pepper. Use a whisk to break up any cheese clumps and ensure everything is evenly distributed.
Add the 0.25 tsp xanthan gum (if using) to the dry mixture. This optional ingredient helps prevent clumping and creates an ultra-smooth texture. Whisk again until the gum is fully incorporated and no dry spots remain. The mixture should look like a fine, powdery blend with no visible cheese chunks.
Gradually Add Hot Liquid
In a separate saucepan, heat 2 cups of milk (or your preferred liquid) over medium heat until it reaches 185°F. This temperature is crucial—it's hot enough to melt the cheese completely without scorching. Watch carefully as the milk heats, stirring occasionally to prevent hot spots.
Slowly pour the hot milk into the dry cheese mixture while whisking continuously. This gradual addition prevents clumping and ensures even distribution of the dry ingredients. Whisk vigorously for 1-2 minutes until the mixture becomes smooth and creamy. The sauce should thicken noticeably as the cornstarch and powdered milk activate.
Cook Until Thick and Silky
Return the saucepan to medium-low heat and transfer the cheese mixture back into it. Stir constantly with a wooden spoon or silicone spatula for 3-5 minutes until the sauce reaches a smooth, velvety consistency. You're looking for a sauce that coats the back of a spoon and leaves a slight sheen—this indicates proper thickening.
The sauce should be thick enough to coat the back of a spoon but still flow smoothly. If it thickens too quickly, whisk in 1-2 tablespoons of warm milk to adjust the consistency. Avoid boiling the sauce, as this can cause it to separate or develop a grainy texture. The final mixture should be completely smooth with no visible cheese particles.
Season and Finish
Taste the sauce and adjust the seasoning if needed. Add a pinch more salt or pepper if desired, or a dash of lemon juice for brightness. The cheese should be rich and flavorful, with a perfect balance between the sharp cheddar and mild Monterey Jack. Stir well to incorporate any additional seasonings.
Remove the sauce from heat immediately after reaching the desired consistency. The sauce will continue to thicken slightly as it cools, so it's better to pull it off heat a touch early. Transfer to a serving bowl or keep warm in a slow cooker for serving over macaroni, broccoli, or your favorite comfort food.
Pro Tips For Making Powdered Cheese Sauce
- Whisk Like Your Life Depends On It: I learned this the hard way—lumpy cheese sauce is a crime. Once the cheese hits the liquid, get that whisk moving in fast, firm strokes. No half-hearted stirring. The goal is to break up clumps before they form, especially with that powdered milk and dry milk powder. If you let it sit, you’re fighting a losing battle.
- Prep Cheese Properly: Skip the pre-shredded cheese unless you’re okay with a sauce that tastes like it’s been sitting in a bag for months. Buy blocks of sharp cheddar and Monterey Jack, then shred them yourself—it’s faster than you think, and the flavor is night and day better. Pulse the cheese in a food processor for even shreds, but don’t overdo it or you’ll end up with cheese dust.
- Heat the Liquid First: Cold liquid + cheese = disaster. Warm your milk mixture (or water, if you’re using that) to at least 160°F before adding the cheese. This isn’t just a suggestion—it’s the thing that keeps your sauce smooth and prevents separation. Use a thermometer if you’re skeptical, but even eyeballing it works if you’re paying attention to the little bubbles forming at the edges.
- Cornstarch Slurry Saves Everything: Mix your cornstarch with a splash of cold milk or water before adding it to the pot—this is non-negotiable. Dumping dry cornstarch into hot sauce will clump like crazy, and your cheese sauce will turn into a gloppy mess. A 1:1 ratio (cornstarch to liquid) works every time, and it thickens faster than you’d expect.
Regional styles of these flavors
Southern Comfort Style
In the South, this powdered cheese sauce becomes the star of baked mac and cheese—think of it as the secret weapon behind the creamy, bubbly top layer.
I remember my grandmother adding a pinch of mustard powder (about ¼ tsp) to the dry mix before blending, which gives that signature tangy depth Southern cooks love. Serve it over cavatappi pasta with crispy fried onions on top for a true Alabama-style dish. 🧀
Midwest Casserole Classic
The Midwest takes powdered cheese sauce to heart in cheesy broccoli casseroles and potato au gratin.
Here, I swap half the cheddar for Colby cheese (about 1 cup) to keep it milder, then mix in 1 tbsp cream of mushroom soup powder (like Campbell's) for that nostalgic, creamy texture. Layer with steamed broccoli and buttery breadcrumbs for a crowd-pleasing side dish. ❄️
New England Clam Chowder Twist
Up north, this sauce transforms New England clam chowder into something extraordinary. I blend in 1 tbsp dried parsley powder and ½ tsp celery salt to the dry mix, then whisk it into warm half-and-half instead of milk for extra richness.
Stir in clams and potatoes at the end for a sauce that clings to every bite. The result? A chowder so creamy it feels like a hug in a bowl. 🍲
Southwest Fiesta Sauce
For a Tex-Mex twist, I replace half the Monterey Jack with pepper jack (about ½ cup) and add 1 tsp cumin powder and ½ tsp smoked paprika to the dry mix.
Mix with warm evaporated milk for a sauce that pairs perfectly with enchiladas or quesadillas. The smoky, slightly spicy flavor makes it a standout for taco nights. 🌶️
Italian-Inspired Risotto Base
In Italian-American kitchens, this powdered sauce becomes the shortcut to creamy risotto. I blend in 1 tbsp dried parsley and ½ tsp nutmeg to the mix, then whisk it into warm chicken broth instead of milk.
Stir into cooked Arborio rice with sautéed mushrooms for a restaurant-worthy risotto in minutes. The nutmeg adds that classic Italian touch. 🍝

Frequently asked questions
Can I use this powdered cheese sauce for dishes other than mac and cheese?
This versatile sauce works beautifully over baked potatoes, grilled cheese sandwiches, or even as a dip for veggie sticks. The silky texture clings to everything from broccoli casseroles to enchiladas. Just adjust the liquid ratio—use half-and-half for extra richness or chicken broth for savory dishes.
Why does my powdered cheese sauce get grainy when mixed?
Graininess usually happens when the cheese isn't fully melted or the liquid isn't hot enough. Always heat your milk to 185°F and whisk continuously while adding it to the dry mix. For extra smoothness, sift the dry ingredients before blending or add 1/4 tsp xanthan gum to prevent clumping. Stirring constantly for 3-5 minutes on low heat also helps.
How do I store the dry powdered cheese mix?
Keep the powder in an airtight container with a silicone desiccant packet to absorb moisture. It stays fresh for 6 months in a cool, dark pantry. For longer storage, freeze portions in 1/4 cup measures—just scoop and mix when needed. Label containers with dates to track freshness. The sauce itself keeps for 3-4 days in the fridge or 3 months frozen.
Can I make this sauce without dairy?
Yes! Swap the milk for unsweetened almond milk or oat milk and use vegan cheese powder (like Follow Your Heart) instead of dairy cheeses. Add 1/2 tsp nutritional yeast for a cheesy flavor. The texture will be slightly lighter, but it still works perfectly for vegan mac and cheese or grilled cheese.
What’s the best way to reheat leftover sauce?
Reheat gently on low heat with a splash of milk to restore creaminess. Stir constantly to prevent scorching—never microwave directly as it can split the sauce. For frozen portions, thaw overnight in the fridge first, then reheat slowly. If the sauce thickens too much, whisk in 1-2 tbsp warm milk until smooth.
