Ingredients for america's test kitchen mac and cheese recipe with evaporated milk
Sixteen ingredients transform into America's Test Kitchen's signature ultra-smooth mac and cheese.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lb | Dry, medium or elbow shape |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for roux |
| All-Purpose Flour 🌾 | ½ cup | Diamond Crystal preferred |
| Evaporated Milk 🥛 | 2 cups | Full-fat for creaminess |
| Sharp White Cheddar Cheese 🧀 | 3 cups | Shredded, block preferred |
| Gruyère Cheese 🧀 | 1 cup | Shredded, nutty flavor |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated, fine |
| Heavy Cream 🥛 | ½ cup | Full-fat for richness |
| Yellow Mustard 🌶️ | 1 tbsp | For subtle tang |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Panko Breadcrumbs 🍞 | ½ cup | For crispy topping |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For breadcrumb topping |
| Freshly Grated Nutmeg 🌿 | ¼ tsp | Fine, aromatic |
The cheeses are non-negotiable for that signature restaurant-quality flavor. Sharp white cheddar delivers the tangy backbone, while Gruyère adds depth and Parmesan brings umami richness. For the best quality, purchase block cheeses and shred them yourself—pre-shredded contains anti-caking agents that prevent smooth melting. Whole Foods Market and specialty cheese shops carry excellent options, but any well-stocked grocery store will have suitable cheddar. The evaporated milk is equally critical—it contains more fat than regular milk, which creates that velvety texture without separation.
No evaporated milk? Whole milk plus 1 tablespoon powdered milk per cup mimics its fat content. Substituting Gruyère with Comté or extra-sharp cheddar works well, but the flavor profile shifts slightly. For a dairy-free version (though not traditional), full-fat coconut milk can replace evaporated milk, though texture will differ. The panko breadcrumbs should be toasted lightly before mixing with olive oil to enhance their crispiness. If you prefer a different breadcrumb, Japanese panko or crushed cornflakes both work beautifully. The mustard is essential for balancing the richness—don't skip it.
Store the dry pasta in an airtight container for up to 12 months, while shredded cheese should be used within 3 days for optimal flavor. The roux mixture can be prepared ahead and refrigerated for 2 days before baking. For best results, assemble the dish just before baking to maintain the crispy topping. Leftovers reheat beautifully—cover with foil and warm in a 350°F oven for 15-20 minutes to restore that creamy texture without drying out the sauce.

Step-by-step instructions for america's Test Kitchen mac and cheese
Mastering this recipe delivers silky-smooth texture and perfect consistency every time.
🍳 Step 1: Create the Perfect Roux
Melt the 0.75 cup unsalted butter in a heavy-bottomed pot over medium heat. Once fully melted and foaming subsides, reduce heat to medium-low and whisk in the 0.5 cup all-purpose flour all at once. Cook for exactly 2 minutes, whisking constantly, until the mixture turns a pale golden color and smells nutty.
This is your foundation - don't rush it. The roux should coat the back of a spoon and hold its shape when you run your finger through it. If it darkens too quickly, reduce heat immediately. The proper roux creates that velvety texture without lumps, and this is where it all begins.
🥘 Step 2: Build the Cheese Sauce Gradually
Slowly whisk in the 2 cups evaporated milk over 2-3 minutes, adding it in a thin stream while maintaining constant motion. The sauce will thicken dramatically - keep whisking until it returns to a smooth consistency. Remove from heat and immediately stir in the 3 cups sharp white cheddar cheese, 1 cup gruyère cheese, 0.5 cup parmesan cheese, 0.5 cup heavy cream, 1 tbsp yellow mustard, 1.5 tsp kosher salt, 0.5 tsp ground black pepper, and 0.25 tsp freshly grated nutmeg. Stir until completely melted and smooth.
Here's the secret: the evaporated milk provides built-in thickness while preventing curdling. The gradual addition of milk to the roux creates microscopic fat globules that emulsify perfectly with the cheese. If you see any lumps, strain the sauce through a fine-mesh sieve for absolute silkiness.
🍳 Step 3: Cook the Pasta Al Dente
While the sauce simmers gently (keep it warm over low heat), cook the 1.5 lb elbow macaroni in a separate pot of well-salted water until 1 minute before package directions specify for al dente. Drain thoroughly, reserving 1 cup pasta water, then immediately add the drained pasta to the cheese sauce. Stir vigorously for 2-3 minutes until fully coated and heated through.
This timing is crucial - slightly undercooked pasta absorbs the sauce better without becoming mushy. The reserved pasta water acts as an insurance policy - if the sauce becomes too thick, add it 1 tablespoon at a time until you reach the perfect clingy consistency. The sauce should coat the back of a spoon but still allow the noodles to be visible.
🔥 Step 4: Create the Crispy Topping
Preheat your broiler to high. In a small bowl, toss the 0.5 cup panko breadcrumbs with the 2 tbsp extra-virgin olive oil until evenly coated. Spread the mac and cheese evenly in a 9x13-inch baking dish and sprinkle the breadcrumb mixture over the top. Place under the broiler for 2-3 minutes until the topping turns deep golden brown and begins to smoke slightly at the edges.
Watch this step carefully - you want crispy, not burnt. The breadcrumbs should develop a toasty aroma and crisp texture that contrasts beautifully with the creamy cheese underneath. For even browning, rotate the dish halfway through if needed. The moment it reaches this perfect golden state, remove immediately from the oven.
Pro Tips For Making America'S Test Kitchen Mac And Cheese Recipe With Evaporated Milk
- STIR CONSTANTLY AT FIRST: The roux in this recipe is a make-or-break moment—I learned this the hard way when I walked away for "just a minute" and ended up with lumps. For the first 2-3 minutes of cooking the butter and flour, keep that wooden spoon moving like you’re stirring paint. Once it turns pale golden and smells nutty, you can ease up slightly, but don’t let it brown.
- GRATE CHEESE FINE: Sharp white cheddar loses its edge when it sits in big chunks. Use the smallest holes on your box grater (or pulse in a food processor) so every bite gets that tangy, melty punch. I was skeptical until I tried it—now I can’t go back to the lazy method.
- DON’T SKIP THE WATER BATH: The evaporated milk sauce needs time to thicken properly after mixing. Pouring it over the pasta and letting it sit covered for 10 minutes (yes, even if you’re impatient like me) lets the starches fully absorb. Trust me, the difference between a creamy sauce and a gloppy one is just waiting.
- USE FULL-FAT EVAPORATED MILK: This isn’t the place for skim or reduced-fat. The richness in whole milk evaporated milk is what makes the sauce velvety, not just thick. I tried cutting corners with a lighter version once—big mistake. The sauce turned out thin and chalky. Stick with the full-fat can for that classic, luxurious texture.

Frequently asked questions
Why does this recipe use evaporated milk instead of regular milk?
The evaporated milk creates that signature ultra-smooth texture without lumps. It contains more fat and natural thickening agents than regular milk, which helps emulsify the cheese perfectly. Plus, it adds subtle sweetness that balances the sharp cheddar and nutty Gruyère.
Can I make this mac and cheese ahead of time?
Prepare the roux and cheese sauce up to 2 days ahead and refrigerate. Assemble the dish just before baking to keep the breadcrumb topping crispy. For leftovers, reheat covered in the oven at 350°F for 15-20 minutes to restore that creamy texture without drying out the sauce.
What's the secret to getting that ultra-smooth texture?
The magic happens in the roux—cook it exactly 2 minutes at medium-low heat until pale golden. Then whisk in the evaporated milk gradually while stirring constantly. The key is patience: let the cheese melt slowly over low heat, and strain if you see any lumps. This method creates microscopic fat globules that prevent separation.
Can I substitute Gruyère with another cheese?
Yes! Try Comté or extra-sharp cheddar for similar nutty depth, though the flavor profile will shift slightly. For a creamier option, add ½ cup cream cheese to the sauce. The Gruyère's meltability is key—avoid cheeses with high moisture content like mozzarella, which can make the sauce watery.
Why does my mac and cheese get watery when reheated?
This usually happens when the sauce separates. To fix it, stir in 1-2 tablespoons cold butter while reheating—it helps re-emulsify the sauce. For prevention, always reheat covered and avoid boiling. The evaporated milk in this recipe is designed to resist separation, but adding a splash of heavy cream can help restore richness if needed.
