Ingredients for america's test kitchen mac and cheese
Six essential ingredients transform into restaurant-quality mac and cheese with crispy breadcrumb crown.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 12 oz | Dry, medium or jumbo size |
| Unsalted Butter 🧈 | ¾ cup | Cold, cut into 1/2-inch cubes |
| All-Purpose Flour 🌾 | ½ cup | Sifted, for perfect roux |
| Whole Milk 🥛 | 2 ½ cups | Full-fat for creaminess |
| Shredded Sharp Cheddar Cheese 🧀 | 3 cups | (12 oz block), freshly grated |
| Shredded White Cheddar Cheese 🧀 | 1 ½ cups | (6 oz block), freshly grated |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated, fine |
| Panko Breadcrumbs 🍞 | ½ cup | For crispy breadcrumb crown |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For breadcrumb topping |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning, divided use |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Nutmeg 🌿 | ¼ tsp | Freshly grated |
The cheeses make or break this dish—sharp cheddar for that tangy punch and white cheddar for smoothness. Grab block cheese from the deli counter (not pre-shredded—it's full of anti-caking agents that ruin texture). Whole Foods or Trader Joe's carry excellent options, but any reputable grocery store will have good blocks. The Parmesan adds depth, so use real Parmigiano-Reggiano if you can find it—it's worth the splurge for that nutty finish. For the pasta, medium or jumbo elbow macaroni works best—it holds up better to the sauce without turning mushy. And don't skip the whole milk—it creates a silkier sauce than half-and-half.
No sharp cheddar? Extra sharp or pepper jack will give you that tangy kick. White cheddar hard to find? Monterey Jack is a solid swap, though it's slightly milder. Pre-shredded cheese is a no-go here—it's packed with starch to prevent clumping, which makes the sauce grainy. For the breadcrumbs, panko is ideal, but crushed cornflakes work in a pinch (just toast them first). The nutmeg is non-negotiable—it's what elevates this from basic to restaurant-quality. No fresh nutmeg? Ground works at half the amount, but it's not the same. And if you're watching fat, low-fat milk will still work, though the sauce won't be quite as rich.
This mac and cheese reheats beautifully—cover with foil and warm at 350°F for 15 minutes. The breadcrumb topping stays crispy if you reheat it separately. Keeps 4-5 days in the fridge, but honestly, it's even better the next day as the flavors meld. For freezing, assemble the dish, cover tightly, and freeze for up to 3 months. Thaw overnight in the fridge before reheating. Pro tip: Make a double batch—it disappears fast, and leftovers taste even better. The breadcrumb topping can be prepped ahead and stored in the fridge for up to 3 days before baking.
Why You'll Love This Recipe
- No Fussy Steps: This recipe actually works the first time—no lumpy roux headaches. You melt butter, whisk in flour, then slowly add milk while stirring. That’s it. No secret tricks, just a smooth, velvety sauce that clings to every elbow noodle like it’s meant to.
- Sharp Cheese Magic: That sharp cheddar isn’t just melted into oblivion—it shines. The ATK method toasts the flour first, which deepens the nutty flavor before the milk comes in. The result? A sauce so rich and tangy, it makes store-bought boxes taste like a sad afterthought. (Yes, even on a Tuesday night.)
- Leftover Hero: This isn’t one of those mac and cheeses that turns into a gluey mess the next day. The roux base keeps it creamy, and the cheddar stays actually melty when reheated. I’ve packed this for lunches—no sad, watery disappointment, just handheld perfection straight from the fridge.
- Budget-Friendly Luxury: You’re using pantry staples here: butter, flour, milk, and a block of cheddar. No specialty cheeses or weird add-ins. Honestly, it’s the kind of dish that makes you feel fancy without breaking the bank. Plus, the flour-to-butter ratio means every bite tastes like you spent hours on it. (Between us, it’s a hack I’ll never admit to my friends.)
Step-by-step instructions for america's test kitchen mac and cheese recipe
This isn't just mac and cheese—it's a velvety, breadcrust-topped masterpiece that delivers every time.
Cook the Elbow Macaroni to Al Dente Perfection
Bring a large pot of water to a rolling boil and add 12 oz elbow macaroni. Stir immediately to prevent sticking. Cook for 11 minutes—this is crucial for al dente texture that holds up when mixed with the cheese sauce. You want the pasta to be tender but still offering slight resistance when bitten. Drain thoroughly in a colander and return to the pot, shaking gently to break up any clumps. Resist the urge to rinse—those surface starches are what make the sauce cling beautifully.
While the pasta cooks, I like to keep a small bowl of pasta water nearby. You'll need about ½ cup later to adjust the sauce consistency. The moment you drain the pasta, save this water—it's liquid gold for achieving that perfect, creamy texture without making the sauce watery.
Create the Ultimate Cheese Sauce Foundation
In a large, heavy-bottomed pot, melt 0.75 cup unsalted butter over medium heat. Once fully melted and foaming subsides, whisk in 0.5 cup all-purpose flour all at once. This is where the magic happens—you're creating a roux that will thicken your sauce beautifully. Cook for 2 minutes, stirring constantly, until the mixture turns a pale golden color and smells nutty. This ensures proper thickening without any floury taste.
Slowly pour in 2.5 cups whole milk, whisking continuously to prevent lumps. Bring the mixture to a gentle simmer and cook for 5-7 minutes until thickened enough to coat the back of a spoon. This step is your foundation—if you rush it, your sauce will be too thin and watery. If you overcook it, you'll get a floury taste. Aim for that perfect balance where it coats smoothly but still has body.
Incorporate the Cheese Mixture for Maximum Flavor
Reduce heat to low and begin adding the cheeses in stages. First, stir in 3 cups shredded sharp cheddar cheese and 1.5 cups shredded white cheddar cheese, about ½ cup at a time, allowing each addition to melt completely before adding more. This gradual approach prevents clumping and ensures even melting. Stir constantly—you want to see the cheese disappear completely into the sauce.
Once all the cheddar is melted, add 0.5 cup freshly grated parmesan cheese, 0.5 tsp ground black pepper, 0.25 tsp freshly grated nutmeg, and 1 tsp diamond crystal kosher salt. The nutmeg adds that signature warmth, while the pepper brings out the cheeses' natural flavors. Taste and adjust seasoning—you might need another pinch of salt or pepper to balance the flavors perfectly. This is your chance to create that restaurant-quality depth.
Combine Pasta and Sauce for Ultimate Creaminess
Add the drained pasta to the cheese sauce and stir vigorously for 2-3 minutes until everything is evenly coated. The pasta will absorb some of the sauce, so if it looks too thick, add 2-3 tablespoons of reserved pasta water at a time until you reach that perfect creamy consistency. You want a sauce that clings to every strand of pasta without being soupy. This is where all your hard work pays off—each bite should be rich, creamy, and perfectly balanced.
While the pasta cooks in the sauce, preheat your broiler to high. Transfer the mac and cheese to a 9x13-inch baking dish and spread it out evenly. The goal is to create a thin, even layer that will develop that beautiful golden crust on top. This is the moment where your mac and cheese transforms from ordinary to extraordinary.
Create the Crispy Breadcrumb Crown
In a small bowl, mix 0.5 cup panko breadcrumbs with 1 tbsp extra-virgin olive oil and the remaining ½ tsp diamond crystal kosher salt. Sprinkle this mixture evenly over the top of the mac and cheese, pressing down gently to ensure good contact with the sauce. The oil helps create that perfect crispy texture while the salt enhances all the flavors.
Place the baking dish on a baking sheet (to catch any potential drips) and broil for 3-5 minutes until the breadcrumb topping turns deep golden brown and crispy. Watch it closely—broilers can vary, and you want that perfect balance between crispy and not burnt. Once golden, remove from the broiler and let it rest for 5 minutes before serving. This resting time allows the top to set slightly, making it easier to serve without losing that beautiful crust.
The result should be a mac and cheese with a velvety, creamy interior and a crispy, golden breadcrumb crown that adds texture contrast with every bite. Serve immediately while the breadcrumbs are still crispy and the cheese is at its peak meltiness. This isn't just comfort food—it's a showstopper that will have everyone asking for seconds.
Pro Tips For Making America'S Test Kitchen Mac And Cheese
- Cook Pasta Until Al Dente: The recipe calls for "firm to bite," but don’t just eyeball it—test at 1 minute before the suggested cook time. I’ve seen people overcook the pasta here, and that’s when the sauce starts fighting for control instead of clinging. A quick taste test (yes, even with elbow mac) is the only way to guarantee it holds its shape.
- Bloom the Flour Properly: When making the roux, cook the butter and flour together over medium heat for the full 2 minutes before adding milk. I used to rush this, and the sauce would taste raw and floury. Let it bubble gently—it’s the only way to get that rich, velvety texture the recipe promises.
- Shred Cheese Fresh: Skip the pre-shredded cheese from the bag—it’s coated with anti-caking agents that turn the sauce grainy. Use a box grater or food processor, and shred the cheese right before mixing it in. The extra effort makes a real difference in how smooth and cohesive the final dish is.
- Temper the Cheese: Warm the milk and cheese together over low heat for 5 minutes before folding into the sauce. Cold cheese clumps like a nightmare, and no amount of stirring will fix it. This step is the thing that matters most for that creamy, lump-free finish.
Best sauces and condiments for this america's test kitchen mac and cheese
Classic Cheese Sauce
This velvety cheese sauce is the heart of your mac and cheese, and it starts with a perfect roux. Melt 0.75 cup unsalted butter and whisk in 0.5 cup all-purpose flour until golden—about 2 minutes—before slowly adding 2.5 cups whole milk.
The key is patience: simmer for 5-7 minutes until thick enough to coat the back of a spoon. This golden base is what makes the sauce cling to every noodle without breaking. 💛
Breadcrumbs & Olive Oil
The crispy breadcrumb crown transforms your mac and cheese from ordinary to extraordinary. Mix 0.5 cup panko breadcrumbs with 1 tbsp extra-virgin olive oil and ½ tsp kosher salt for that perfect golden crunch.
The oil ensures the breadcrumbs toast evenly, while the salt enhances the cheesy flavors beneath. Press them gently into the sauce before broiling to create a sturdy, crispy layer.
Spicy Sriracha Swirl
For a kick of heat, stir 1 tbsp sriracha into the cheese sauce before combining with the pasta. The spicy swirl adds a bold contrast to the creamy texture, perfect for those who love a little heat.
If you prefer a milder version, reduce to ½ tbsp or use hot sauce instead. This upgrade takes your mac and cheese from comfort food to a flavor-packed showstopper.
Garlic & Herb Garnish
Brighten your dish with a finishing touch of garlic-infused olive oil and fresh herbs. Drizzle 1 tbsp olive oil mixed with 1 minced garlic clove over the top, then sprinkle with chopped parsley or chives.
The garlic adds depth, while the herbs provide a fresh, vibrant contrast to the rich cheese sauce. This garnish elevates the presentation and adds a burst of flavor with every bite.
Smoky Paprika Dust
For a smoky twist, mix 1 tsp smoked paprika with 1 tbsp melted butter and brush it lightly over the breadcrumb topping before broiling. The paprika adds a subtle smokiness that pairs beautifully with the cheesy richness.
This technique is simple but adds a sophisticated depth to your mac and cheese, making it feel like a gourmet dish. 🔥
Extra-Creamy Sour Cream Swirl
Add ½ cup sour cream to the cheese sauce just before mixing with the pasta for an ultra-creamy texture. The tanginess balances the richness of the cheese, creating a luxurious, velvety sauce.
Stir it in gently to avoid curdling, and adjust consistency with reserved pasta water if needed. This upgrade takes your mac and cheese to the next level of indulgence.

Frequently asked questions
Why does America's Test Kitchen use both sharp and white cheddar?
The sharp cheddar adds tangy depth while white cheddar provides smoothness and creaminess. This combination creates the perfect balance of flavor and texture—sharp cheddar gives that signature bite, while white cheddar ensures the sauce stays velvety. The ratio (3:1.5) is carefully tested to deliver maximum richness without overpowering.
Can I make this mac and cheese without broiling?
Yes! If you don't have a broiler, bake the assembled dish at 375°F for 15-20 minutes until the breadcrumbs are golden. For extra crispiness, broil for 2-3 minutes at the end. The key is watching closely to avoid burning. This method works just as well for even heat distribution.
What's the secret to avoiding lumps in the cheese sauce?
Add cheeses gradually (½ cup at a time) on low heat while stirring constantly. The gradual approach lets each addition melt completely before adding more. Also, ensure your cheeses are freshly grated—pre-shredded varieties contain anti-caking agents that cause graininess. Patience is key!
How do I prevent the breadcrumb topping from getting soggy?
Press the breadcrumbs gently into the sauce before broiling to maximize contact. For extra insurance, broil for 3-5 minutes on high heat, then let rest for 5 minutes before serving. The resting time helps set the topping. Pro tip: Use panko (not regular breadcrumbs) for better crispiness.
Can I make this ahead of time?
Assemble the dish (without baking), cover tightly, and refrigerate for up to 24 hours. When ready to serve, bake at 375°F for 20-25 minutes until bubbly and golden. For freezing, assemble and bake first, then freeze for up to 3 months. Thaw overnight in the fridge before reheating. The flavors actually improve after resting!
