Ingredients for america's test kitchen mac and cheese
Sixteen ingredients transform into restaurant-quality mac and cheese with velvety cheddar swirls and crispy breadcrumb crown.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 12 oz | Medium or jumbo size preferred |
| Unsalted Butter 🧈 | ¾ cup | Cold, cut into 1-inch cubes |
| All-Purpose Flour 🌾 | ½ cup | Sifted for smooth roux |
| Sharp White Cheddar Cheese 🧀 | 3 cups | Finely grated, 2 years aged minimum |
| Cream Cheese 🧀 | 8 oz | Full-fat, room temperature |
| Whole Milk 🥛 | 1 ½ cups | Warmed to 160°F |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For seasoning, not roux |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Freshly Ground Nutmeg 🌿 | ¼ tsp | Microplane for fine texture |
| Panko Breadcrumbs 🍞 | ½ cup | Japanese-style, toasted |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For breadcrumb crown |
| Garlic Powder 🧄 | ½ tsp | For breadcrumb seasoning |
| Dried Parsley Flakes 🌿 | ½ tsp | For garnish |
The cheese selection is non-negotiable for that signature ultra-smooth texture. Sharp white cheddar aged at least 2 years delivers the perfect balance of tang and creaminess—avoid mild varieties or pre-shredded cheese, which contains anti-caking agents that prevent proper melting. For the best results, Whittier Farms or Cabot cheddars are professional-grade choices available at specialty grocers. The cream cheese must be full-fat; low-fat versions compromise the sauce's richness. When grating the cheddar, use a box grater for uniform particles that melt evenly. For the roux, Gold Medal all-purpose flour is preferred for its protein content, which creates a smoother sauce.
Substitutions require strategic adjustments to maintain texture and flavor. If you lack sharp cheddar, Parmigiano-Reggiano in equal quantity adds depth but may alter the color slightly. For dairy-free adaptations, nutritional yeast blended with olive oil can mimic some cheesy notes, though the texture will differ significantly. Panko breadcrumbs can be swapped for Italian-style breadcrumbs, but Japanese panko provides superior crispiness due to its lighter, airier structure. The garlic powder in the breadcrumb crown can be replaced with 1/4 teaspoon minced garlic if you prefer fresh flavor, though it requires additional toasting time. For those avoiding gluten, certified gluten-free panko works well, though the crown may be slightly less crisp.
Proper storage ensures the dish maintains its restaurant-quality texture. The assembled mac and cheese should be refrigerated in an airtight container for up to 4 days, though the breadcrumb crown loses crispness after 2 days. For longer storage, freeze the assembled dish (without the crown) for up to 3 months. When reheating, cover with a damp paper towel to prevent drying. The breadcrumb crown is best prepared fresh but can be toasted separately and stored in an airtight container for 1 day. For optimal presentation, assemble the dish just before serving to maintain the crown's crispness.
Why You'll Love This Recipe
- One-Pot Magic: I swear by this recipe because it’s actually one pot—no strainer, no extra bowls. The roux builds right in the pot with butter, flour, and milk, then the cheeses melt into a velvety sauce while the pasta cooks. Honestly, I’ve made mac and cheese for years, and this is the first time I didn’t feel like I was doing dishes and a science experiment.
- Cheese Overload (The Good Kind): Sharp white cheddar and cream cheese team up for a sauce that’s both rich and slightly tangy—not too heavy, not too bland. The secret’s in the slow melt and whisking, which gives it that perfect, stretchy texture. Between us, my picky husband actually licks the plate clean. That’s saying something.
- Weeknight Hero: This is my go-to when I’m exhausted but still need to feed the family. The pasta cooks in the same pot as the sauce, so it’s done in 20 minutes flat. I’ll even make a double batch on Sundays and freeze half—because reheating it later? Still creamy, still delicious. (Yes, even on a Tuesday night.)
- Budget-Friendly Luxury: Elbows, butter, and cheese aren’t exactly cheap, but this recipe stretches ingredients just right. A single batch feeds four, and the leftovers taste just as good cold the next day (great for lunches). Plus, the cream cheese adds that restaurant-quality richness without breaking the bank. My wallet and taste buds win.
Step-by-step instructions for america's Test Kitchen mac and cheese
This method delivers ultra-smooth cheddar swirls with a crispy breadcrumb crown—every technique matters.
Cook the Elbow Macaroni to Perfect Al Dente
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 ensures the pasta is al dente with a slight bite, as overcooking releases too much starch into the roux later. Reserve 1 cup pasta water before draining, as this starchy liquid will be essential for emulsifying the cheese sauce.
Drain the pasta in a colander and return it to the pot. Toss immediately with 1 tbsp extra-virgin olive oil to prevent clumping. Keep the pot warm over low heat while you prepare the roux—this maintains the pasta's temperature and prevents drying.
Create a Smooth Roux with Butter and Flour
In a 5-quart Dutch oven, melt the 0.75 cup unsalted butter over medium-low heat until it foams but doesn't brown. Whisk in the 0.5 cup all-purpose flour all at once and cook for 2 minutes, stirring constantly with a wooden spoon. This creates a pale blond roux—the foundation for your velvety sauce.
Gradually whisk in the 1.5 cups warmed whole milk, about ¼ cup at a time, allowing each addition to fully incorporate before adding more. The mixture should thicken to a smooth, paste-like consistency. If it looks too thin, whisk in 1 tbsp reserved pasta water to achieve the perfect texture for cheese incorporation.
Incorporate Cheeses for Ultra-Smooth Texture
Reduce heat to low and add the 8 oz cream cheese, stirring until completely melted and smooth. Then, gradually sprinkle in the 3 cups finely grated sharp white cheddar cheese, whisking vigorously after each addition. The cheese should melt into a silky sauce—if it looks grainy, whisk in 1-2 tbsp reserved pasta water to emulsify.
Season immediately with 1.5 tsp diamond crystal kosher salt, 0.5 tsp freshly cracked ground black pepper, and 0.25 tsp freshly ground nutmeg. Taste and adjust seasoning—this is your chance to balance the rich cheddar before adding the pasta. The sauce should coat the back of a spoon with a luxurious, velvety finish.
Combine Pasta and Cheese for Maximum Creaminess
Add the drained pasta to the Dutch oven and toss gently but thoroughly with tongs, ensuring every strand is fully coated. The residual heat will finish cooking the pasta while melting the cheese into a cohesive sauce. If the mixture looks dry, whisk in 2-3 tbsp reserved pasta water until it reaches a creamy, clingy consistency.
Transfer the mac and cheese to a 9x13-inch baking dish, spreading it evenly. The sauce should be smooth with no visible cheese lumps—this is where precise technique pays off. Cover loosely with foil and let it rest for 10 minutes while you prepare the breadcrumb topping.
Create the Crispy Breadcrumb Crown
Preheat your oven to 375°F. In a small bowl, combine the 0.5 cup panko breadcrumbs, 0.5 tsp garlic powder, and remaining 1 tbsp extra-virgin olive oil. Mix until evenly coated—this ensures crispy, flavorful crumbs rather than dry, flavorless ones.
Sprinkle the breadcrumb mixture evenly over the mac and cheese, pressing down lightly with the back of a spoon to help it adhere. Bake uncovered for 15-20 minutes until the topping is deep golden brown and the edges bubble slightly. Garnish with 0.5 tsp dried parsley flakes before serving immediately.
Pro Tips For Making America'S Test Kitchen Mac And Cheese
- Cook the Pasta Al Dente: The recipe calls for elbow macaroni, and I learned this the hard way—undercooked pasta turns mushy when mixed with the cheese sauce. Test a piece by biting into it raw: it should have a slight bite, not be fully soft. Drain it right away and toss with a tiny bit of pasta water (just 1-2 tablespoons) to help the sauce cling.
- Grate the Cheese Fine: Sharp white cheddar is the star, but I used to buy pre-shredded cheese—big mistake. The anti-caking agents make the sauce grainy and watery. Use a box grater or food processor for a powdery texture, and mix in the cream cheese while the roux is still hot (it dissolves better).
- Don’t Rush the Roux: Whisking butter and flour over medium heat until it’s a deep golden brown (about 5-7 minutes) is non-negotiable. I skipped this once and ended up with a bland, pasty sauce. Keep the heat steady—no skipping the color, even if it smells nutty.
- Stir Constantly After Adding Milk: Once you pour in the milk, the sauce thickens fast. I’ve had it split into lumps because I walked away for "just a minute." Keep stirring like your life depends on it for the first 2-3 minutes after adding the milk to avoid gluey globs.
Dietary considerations for this dish
Gluten-Free Adaptations
For gluten-free versions, replace the elbow macaroni with gluten-free pasta like Barilla Gluten-Free or De Cecco Gluten-Free, which cook similarly to traditional pasta. The roux requires substitution too—use gluten-free all-purpose flour blend like Bob's Red Mill 1:1 and add 1 tbsp cornstarch to improve thickening.
The breadcrumb crown becomes the biggest challenge; opt for certified gluten-free panko like Annie's Homegrown and ensure it's toasted in a 375°F oven for 5 extra minutes to compensate for lower starch content. 🌾
Dairy-Free Options
Creating a dairy-free version requires strategic substitutions that mimic the creamy texture. Replace the butter with olive oil or dairy-free margarine like Earth Balance, and use nutritional yeast blended with cashew cream (soaked cashews blended with water) to replicate the cheesy flavor.
For the cheddar, vegan sharp cheddar shreds like Violife work best, though they may require extra 1 tbsp reserved pasta water to achieve smoothness. The breadcrumb crown stays the same but loses its crispy contrast without butter—consider adding 1 tsp melted coconut oil to the mix for extra crunch. 🥛
Lower-Carb Versions
Transform this into a lower-carb dish by swapping the pasta for cauliflower rice or shirataki noodles. For the cauliflower option, sauté 4 cups riced cauliflower in 1 tbsp olive oil for 5 minutes until tender, then proceed with the roux and cheese steps.
If using shirataki noodles, rinse thoroughly and blanch for 2 minutes to remove excess sodium. The breadcrumb crown remains unchanged but adds a satisfying crunch to the lighter base. For extra protein, stir in ½ cup cooked chickpeas with the pasta substitute. 🥦
Vegan Protein Boost
Add plant-based protein to any version by mixing in ½ cup cooked lentils or chickpeas with the pasta. For a cheesy texture without dairy, fold in ½ cup vegan cream cheese like Kite Hill along with the regular cheese.
The lentils work particularly well—their earthy flavor complements the sharp cheddar notes. For the breadcrumb crown, consider adding 1 tbsp ground flaxseed to the mix for extra binding and nutritional boost. The result is a heartier dish that still maintains the signature creamy texture. 💪
Lactose-Intolerant Friendly
For those with lactose intolerance but who can tolerate small amounts of dairy, use lactose-free milk instead of whole milk in the roux. Replace regular cheddar with lactose-free sharp cheddar like Green Valley Organics, which melts smoothly without causing digestive issues.
The cream cheese can be swapped for lactose-free cream cheese like Breyers Lactose-Free. Keep the breadcrumb crown as-is, but reduce the baking time to 12-15 minutes to prevent over-browning while maintaining crispiness. 🧀

Frequently asked questions
Why does America's Test Kitchen use both sharp cheddar and cream cheese?
The sharp cheddar provides that signature tangy depth, while the cream cheese adds smoothness and prevents separation. The combination creates ultra-smooth swirls that cling perfectly to the pasta—something store-bought versions can't replicate. The cream cheese also helps emulsify the sauce, ensuring no graininess.
Can I make this mac and cheese without baking it?
Skip the breadcrumb crown and serve it as a stovetop version. After combining the pasta and cheese sauce, stir in 1 tbsp butter for extra richness and serve immediately with extra breadcrumbs on top. The texture will be creamier but still delicious—just without that crispy crown.
What's the secret to getting that perfect breadcrumb crown?
Toast the panko in the oven for 5 minutes before mixing with olive oil and garlic powder—this removes moisture for maximum crispiness. Press the crumbs down gently after sprinkling to help them adhere, and bake at 375°F until deep golden brown. The key is patience: don't rush the baking time or the crown will be pale and soggy.
How do I fix lumpy cheese sauce?
If you see lumps, immediately whisk in 1-2 tbsp reserved pasta water to emulsify. For stubborn lumps, remove the pan from heat and vigorously stir in 1 tbsp cold butter or 1 tbsp cream cheese—the fat breaks down the cheese particles. If all else fails, strain the sauce through a fine-mesh sieve for silky perfection.
Can I make this ahead of time?
Assemble the dish up to 2 days ahead (without the breadcrumb crown) and refrigerate in an airtight container. Reheat covered with a damp paper towel at 350°F for 20 minutes. For the crown, toast it fresh before serving—it won't reheat crispy. The cheese sauce actually improves overnight as flavors meld!
