Ingredients for annie's mac and cheese sauce
These ten ingredients transform into a velvety sauce with restaurant-quality cheese swirls and buttery richness.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for roux development |
| All-Purpose Flour 🌾 | ½ cup | Diamond Crystal preferred for volume |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Freshly shredded, block preferred |
| Cream Cheese 🧀 | 8 oz | Full-fat, room temperature |
| Whole Milk 🥛 | 1 ½ cups | 2% or whole for creaminess |
| Heavy Cream 🥛 | ¼ cup | For velvety texture |
| Yellow Mustard 🍯 | 1 tbsp | Dijon preferred for depth |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal for precise measurement |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked for aroma |
| Garlic Powder 🧄 | ½ tsp | For subtle savory note |
The roux foundation begins with unsalted butter—use European-style if available, as it has higher fat content for better flavor development. Diamond Crystal flour is recommended for its lighter volume, though regular all-purpose works fine. For the cheddar, block cheese is non-negotiable—pre-shredded contains anti-caking agents that prevent proper melting. The cream cheese should be full-fat (none of that low-fat nonsense) and brought to room temperature for smooth incorporation. I always grab Whole Foods' organic cheddar when possible, but any sharp white variety works if you're on a budget. The milk and heavy cream should be cold when added to prevent premature curdling of the roux.
No sharp cheddar? Pepper jack or Gruyère add complexity, though the tang will differ. Running short on cream cheese? Substitute an extra 0.25 cup of sharp cheddar—the sauce will be slightly tangier but just as creamy. The yellow mustard is crucial for binding and adding depth; if you're avoiding mustard, 1 tsp of white wine vinegar works in a pinch. For the flour, if you don't have Diamond Crystal, add an extra 1 tbsp as it's slightly denser. The garlic powder can be swapped for 1/4 tsp of fresh minced garlic if you're feeling fancy, but don't skip it entirely—the subtle savory note balances the richness.
This sauce reheats beautifully—store in an airtight container with a thin layer of milk on top to prevent skin formation. Keeps 5-6 days in the fridge, though I find it tastes best within 3 days. For longer storage, freeze in ice cube trays—thaw overnight in the fridge and whisk to restore creaminess. The cheese swirls develop more dramatically when reheated, so always warm gently on low heat. Portion into ramekins for individual servings or a large dish for family-style meals. Leftovers make incredible grilled cheese sandwich fillings or steak toppings.

Step-by-step instructions for annie's mac and cheese sauce
This method delivers restaurant-quality cheese sauce with perfect texture—silky yet thick, with those signature swirls.
Develop the Roux for Maximum Flavor
In a heavy-bottomed saucepan over medium heat, melt the 0.5 cup Unsalted Butter until it foams but doesn't brown. Immediately whisk in the 0.5 cup All-Purpose Flour to create a smooth paste. This is your roux foundation—keep it moving constantly to prevent burning.
Cook for 1-2 minutes until the mixture turns a pale golden color and smells nutty. You're looking for a light roux, not dark—this ensures a velvety sauce rather than a bitter one. The cold cubed butter helps create tiny air pockets that give the sauce its signature silkiness. If it starts to darken too quickly, reduce the heat slightly and keep whisking.
Cook the Cheese Mixture to Perfection
Gradually whisk in the 1.5 cups Whole Milk and 0.25 cup Heavy Cream over 2-3 minutes, adding just enough to create a thick, smooth sauce. The mixture should bubble gently but not boil vigorously. Stir in the 2 cups Sharp White Cheddar Cheese and 8 oz Cream Cheese (cut into small cubes for even melting), along with the 1 tbsp Yellow Mustard, 1.5 tsp Kosher Salt, 0.5 tsp Ground Black Pepper, and 0.5 tsp Garlic Powder.
Continue cooking on low heat for 5-7 minutes, stirring constantly, until the cheese melts completely and the sauce thickens to a creamy consistency. You'll see the sauce transform from chunky to smooth—this is where the magic happens. If it starts to separate, whisk vigorously to re-emulsify. The cream cheese adds luxurious body while the sharp cheddar delivers that signature tangy flavor.
Finish with Velvety Texture
Remove the sauce from heat and let it rest for 5 minutes to fully thicken. This resting period allows the starches to fully hydrate and the sauce to develop its characteristic silkiness. The residual heat will continue cooking the sauce gently without risking curdling.
For those signature cheese swirls, transfer the sauce to a blender or use an immersion blender to achieve a completely smooth texture. Return it to the saucepan and reheat gently if needed. The sauce should coat the back of a spoon and hold its shape when drizzled—this is the perfect consistency for coating pasta without becoming gloppy. The mustard adds subtle depth that balances the richness, while the garlic powder provides a subtle savory note that elevates the entire dish.
Pro Tips For Making Annie'S Mac And Cheese Sauce
- WHISK THE ROUX FAST: Get that butter and flour cooking over medium-high heat right away—no simmering. I learned this the hard way when my sauce turned into glue after sitting too long. Keep it bubbling gently, not browned, then immediately add the milk to stop the cooking.
- GRATE CHEESE FINE: Sharp white cheddar loses its punch if it sits in clumps. Use a box grater or food processor to get it as fine as possible, then melt it in the sauce off the heat. I skip the microwave here—just stir until fully incorporated, or you’ll end up with stringy cheese.
- TEMPER THE MILK: Warm the milk slightly before adding it to the roux—just enough to feel lukewarm to the touch. Cold milk shocks the butter and makes the sauce seize. I keep a small saucepan nearby and heat it to about 100°F (38°C) while the butter melts.
- STIR IN CREAM CHEESE LAST: Add the cream cheese when the sauce is thick but still liquid, not when it’s fully reduced. If you dump it in too early, it’ll clump like sad cottage cheese. Stir in small pieces until fully melted, then taste—you might need a splash more milk to smooth it out.
Make-ahead tips for this annie's mac and cheese sauce
Prep Ahead Sauce
Make this sauce up to 3 days in advance—it actually tastes better after resting as the flavors meld together. Let it cool completely before storing in an airtight container with a thin layer of milk on top to prevent a skin from forming.
I like to portion it into ramekins for easy reheating later. The cheese swirls become even more dramatic after chilling and reheating, giving you that restaurant-quality texture. ❄️
Freezer-Friendly
For longer storage, freeze the sauce in ice cube trays—this makes it easy to thaw just what you need. Once frozen, transfer the cubes to a freezer bag with all the air squeezed out to prevent freezer burn.
When ready to use, thaw overnight in the fridge and whisk vigorously to restore that velvety consistency. The sauce keeps well for up to 3 months without losing its creamy texture. 🥶
Reheat Like a Pro
Always reheat the sauce gently on low heat to prevent curdling or separation. I add a splash of milk or heavy cream if the sauce looks too thick after reheating. For best results, warm it in a heavy-bottomed saucepan over medium-low heat for 5-7 minutes, stirring constantly.
If you're using frozen portions, let them thaw in the fridge first before reheating. The sauce should be smooth, silky, and ready to coat your pasta perfectly. 🔥
Make-Ahead Meal Prep
Pair this sauce with pre-cooked pasta to create a complete meal ahead of time. Cook your pasta al dente, drain, and toss it with a little olive oil to prevent sticking. Store the pasta and sauce separately in the fridge, then combine them when ready to serve.
This is perfect for busy weeknights—just reheat and enjoy. For extra convenience, assemble the entire mac and cheese in a baking dish, cover tightly, and bake at 350°F for 20-25 minutes before serving. 📅
Sauce for Multiple Uses
This versatile sauce isn't just for mac and cheese—use it as a dipping sauce for burgers or steak, a topping for baked potatoes, or even a cheesy pasta sauce. Portion it into small jars for individual servings or keep it in a large container for family-style meals.
The sauce reheats beautifully, so you can make a big batch and use it throughout the week without worrying about leftovers. 💡
Cheese Swirl Trick
For the most dramatic cheese swirls, melt an extra 1-2 tablespoons of butter in a small pan and stir it into the sauce just before serving. This adds extra richness and helps create those beautiful swirls when you drizzle it over the pasta.
If you're serving it as a dip, garnish with a sprinkle of freshly cracked black pepper or a pinch of paprika for added visual appeal. The swirls are the signature touch that makes this sauce feel extra special. ✨

Frequently asked questions
Why does this sauce use both sharp cheddar and cream cheese?
The sharp cheddar delivers that signature tangy flavor while the cream cheese adds luxurious body and prevents separation. The combination creates a perfectly balanced sauce that's both creamy and rich without being too heavy. The cream cheese also helps bind the sauce together during reheating.
Can I make this sauce without a blender?
Yes! If you don't have a blender, whisk the sauce vigorously for 2-3 minutes after removing it from heat. The constant motion helps break up any cheese lumps and creates a smooth texture. For extra silkiness, strain it through a fine-mesh sieve if needed. The key is patience—keep whisking until it reaches that velvety consistency.
What's the secret to preventing lumps in the sauce?
Low and slow heat is your best friend! Keep the sauce on low heat while stirring constantly, and never let it boil. The cream cheese should be cut into small cubes and added gradually to melt evenly. If lumps appear, whisk vigorously or strain the sauce through a sieve. The mustard also helps emulsify the mixture for a smoother finish.
How do I adjust the consistency if it's too thick or too thin?
For a thicker sauce, simmer uncovered for 2-3 minutes to evaporate excess liquid. If it's too thin, whisk in 1 tablespoon of cold butter or 1 tablespoon of flour mixed with water (1:1 ratio) while stirring constantly. For a thinner sauce, gradually add 1 tablespoon of milk at a time until you reach the desired consistency. Always adjust gradually to avoid overcorrecting.
Can I use this sauce as a dip instead of over pasta?
This sauce makes an amazing dip for burgers, steak fries, or even veggie sticks. For extra richness, add a splash of heavy cream** (1-2 tablespoons) before serving. Garnish with freshly cracked black pepper or a sprinkle of smoked paprika for added visual appeal. The velvety texture makes it perfect for dipping—just make sure it's fully cooled before serving to prevent burning.
