Ingredients for annie's mac and cheese sauce

Pantry staples plus a few specialty touches for that signature velvety crunch.

The butter and flour combo is non-negotiable for that perfect roux—use cold butter to avoid lumps, and whisk constantly over low heat until it's golden. Sharp cheddar is a must (the kind that melts smoothly, not the pre-shredded dust). I grab mine from Whole Foods or Trader Joe's—their blocks shred perfectly. For the celery, use the stringy bottoms (the ones you'd normally toss)—they're packed with flavor and give that signature crunch. Fresh garlic is ideal, but jarred minced works in a pinch if you're short on time.

No sharp cheddar? Gruyère or white cheddar works too, but the tang will differ. Heavy cream can be swapped for half-and-half if you're watching calories, though it won't be as rich. Mustard hater? Skip it—just know the sauce will be slightly less complex. Celery stems too fibrous? Blend them first for a smoother texture, though you'll lose some crunch. The roux is the star here—don't rush it. If it browns too fast, lower the heat and keep whisking. That golden color is your goal.

This sauce keeps beautifully—3-4 days in the fridge, 3 months frozen. For freezing, cool it completely first, then portion into airtight containers. The celery crunch disappears when reheated, so add fresh chopped celery stems when serving leftovers. Double the batch if you're feeding a crowd—it disappears fast. And trust me, leftovers taste even better the next day as everything melds together.

Step-by-step instructions for annie's mac and cheese sauce

Here's how to make that ultra-smooth, velvety sauce without ever turning on the oven.

In a small skillet over medium heat, melt 0.5 cup unsalted butter until it foams but doesn't brown. Add the 0.5 cup chopped celery stems and 2 minced garlic cloves, cooking for 3-4 minutes until the celery softens and becomes translucent. You're not trying to caramelize here—just get those flavors infused into the butter.

Remove from heat and stir in 1 tbsp yellow mustard and 0.5 tsp ground black pepper. Set this mixture aside—it'll be our secret weapon for adding texture later. The celery will soften into the sauce while keeping just enough bite to give that signature crown crunch we all love.

In a large saucepan, melt the remaining 0.5 cup unsalted butter over medium heat until it's completely liquid but not browned. Add the 0.5 cup all-purpose flour all at once and whisk vigorously for 1-2 minutes until the mixture turns a light golden color and smells nutty.

This is your roux—the foundation of our sauce. Don't walk away; keep whisking until it's smooth and free of any raw flour taste. If it starts to darken too quickly, reduce the heat slightly. You want it to be a light blond color, not browned—we're making a sauce, not gravy.

Slowly pour in 0.5 cup milk while whisking constantly to prevent lumps from forming. Let the mixture cook for 2-3 minutes until it thickens slightly. Then gradually add the 1 cup heavy cream, whisking continuously, and let it simmer for another 3-4 minutes until the sauce is smooth and velvety.

Here's where the magic happens: gradually add the 2 cups shredded sharp cheddar cheese a handful at a time, whisking until each addition is completely melted. The sauce should be thick enough to coat the back of a spoon but still flow smoothly. If it gets too thick, add a splash more milk or cream to reach your desired consistency.

Remove the sauce from heat and stir in the celery-butter mixture you prepared earlier. The celery will soften slightly but maintain just enough texture to give that satisfying crunch when you bite into it. Season with the 1 tsp salt, tasting as you go to adjust to your preference.

Let the sauce sit for 5 minutes off the heat—this allows all the flavors to meld together perfectly. The cheese should be completely melted, and the sauce should be silky smooth with just a hint of celery crunch throughout. If you're serving it immediately, give it one last stir before pouring over your pasta.

This sauce is best served immediately over cooked macaroni, but it can also be used as a creamy side dish or even as a filling for baked potatoes. The no-bake method means you get that restaurant-quality texture without any oven time, and the celery crown adds that signature crunch that makes this sauce so special.

For the best experience, serve right away while the sauce is still warm and the celery maintains its subtle crunch. If you're making this ahead, you can prepare the sauce up to the point before adding the celery crown and reheat gently on the stove, then stir in the celery mixture just before serving.
