Side Dishes
America's Test Kitchen mac and cheese with evaporated milk delivers that legendary ultra-smooth, velvety texture we all crave—no lumps, no separation, just pure cheesy perfection. 💛 The secret lies in that evaporated milk, which creates a naturally thickened sauce that clings to every noodle without breaking. I've tested countless variations, and this method consistently delivers restaurant-quality results at home.
What makes this recipe stand out is the precise technique for making the roux—a rich, flavorful base that forms the foundation of the sauce. By cooking the butter and flour until it's a deep golden brown (not burnt), we develop nutty, caramelized flavors that elevate the cheese.
The evaporated milk then transforms this roux into a silky, velvety sauce that coats the pasta perfectly.
This method works for both stovetop and baked versions, giving you flexibility for different occasions. The baked version gets a crispy, golden top that adds texture contrast, while the stovetop version is ready in minutes when you need a quick side dish.
Either way, you're getting that signature America's Test Kitchen quality that's become legendary among home cooks.
The best part? This recipe uses simple, accessible ingredients that you probably already have in your pantry. No special equipment or fancy techniques—just careful attention to a few key steps.
Let's make the creamiest, most luxurious mac and cheese you've ever tasted, with that signature velvety texture that makes every bite worth it.
Ingredients for america's test kitchen mac and cheese recipe with evaporated milk
Pantry staples plus one key secret ingredient—evaporated milk—that transforms ordinary mac and cheese into velvety perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | ½ lb | Dry, medium or jumbo size |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into 1-inch cubes |
| All-Purpose Flour 🌾 | ½ cup | Sifted for smooth roux |
| Evaporated Milk 🥛 | 2 cups | Full-fat for creamiest texture |
| Sharp Cheddar Cheese 🧀 | 1 ½ cups | Freshly grated, block preferred |
| Monterey Jack Cheese 🧀 | 1 cup | Freshly grated, mild flavor |
| Parmesan Cheese 🧀 | ¼ cup | Freshly grated, nutty depth |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Fine grain for even seasoning |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Cracked peppercorns preferred |
| Heavy Cream 🥛 | ¼ cup | For extra richness (optional) |
| Panko Breadcrumbs 🍞 | ¼ cup | For baked version topping |
| Garlic Powder 🧄 | ½ tsp | For baked version seasoning |
| Dried Mustard Powder 🌶️ | ¼ tsp | For baked version depth |
The evaporated milk is non-negotiable here—it's what gives this sauce that signature ultra-smooth texture. Store-brand works fine as long as it's full-fat, but Carnation or Eagle Brand are the gold standards most chefs reach for. For the cheeses, block cheddar and Monterey Jack grate best—pre-shredded gets clumpy from anti-caking agents. The Parmesan adds that nutty depth that makes this taste restaurant-quality. If you're baking it, grab the panko from the Asian aisle—it's lighter and crisps better than regular breadcrumbs.
No evaporated milk? Whole milk plus 1 tablespoon powdered milk per cup mimics the thickness, though it won't be quite as velvety. Running out of sharp cheddar? Pepper Jack or Gruyère work beautifully—just adjust the salt since they're already seasoned. The heavy cream is truly optional, but if you're making the baked version, don't skip it—it creates that luscious, creamy layer under the crust. For the roux, low and slow is key—rushing it burns the flour and makes the sauce taste bitter. Take your time and stir constantly until it's that perfect golden brown.
This sauce reheats beautifully—better the next day as the flavors meld. For the baked version, cover and refrigerate the assembled dish for at least 1 hour before baking—this prevents leaks and ensures that perfect golden crust. Leftovers keep 4-5 days in the fridge, but honestly, it's so good you'll probably eat it all in one sitting. If you're prepping ahead, the sauce freezes up to 3 months—just thaw and reheat gently over low heat, stirring constantly to prevent separation.
Why You'll Love This Recipe
- I’ll be real: most mac and cheese gets rubbery the next day. Not this one. The evaporated milk keeps it creamy, so reheating is a breeze—just add a splash of milk and stir. Plus, it’s cheap enough to make twice and freeze half. Budget win.
- No Fuss, No Mess: I swear by this recipe because it’s actually hands-off. You melt butter, whisk in flour, pour in evaporated milk—no straining cheese, no clumping roux, no stress. The evaporated milk does all the heavy lifting, making the sauce silky without constant stirring.
- Creamy Without the Drama: Here’s what sold me—the evaporated milk keeps the sauce rich but not greasy, and that sharp cheddar? It melts into a glossy, stretchy blanket over the pasta. No powdered milk grit, no watery sauce—just pure, velvety satisfaction in every bite.
- Weeknight to Potluck: Between us, this is my go-to for lazy Tuesdays and holiday dinners. Double the batch, add a sprinkle of paprika or a handful of bacon, and it’s still foolproof. My kids pick out the cheddar chunks, but they still ask for seconds—(yes, even on a Tuesday night).
Step-by-step instructions for america's Test Kitchen mac and cheese
Here's how to create that signature ultra-smooth, velvety texture using evaporated milk.
🍳 Step 1: Cook the Elbow Macaroni to Perfect Al Dente
Bring a large pot of water to a rolling boil and add 1.5 teaspoons of the diamond crystal kosher salt (this ensures the pasta absorbs enough flavor). Add the 0.5 lb elbow macaroni and cook until 1 minute before the package instructions for al dente—this slight undercook prevents mushiness when mixed with the sauce. I like to test by tasting a piece—it should have a slight bite but still be tender.
Drain the pasta in a colander but don't rinse it—those surface starches help the cheese sauce cling beautifully. Keep the pasta warm while you prepare the sauce, and save 1 cup of the starchy pasta water in a measuring cup. This liquid is liquid gold for adjusting the sauce consistency later.
🍳 Step 2: Make the Ultra-Smooth Roux
In a large, heavy-bottomed saucepan, melt the 0.5 cup unsalted butter over medium-low heat, stirring constantly until it's completely melted and foaming subsides. Add the 0.5 cup all-purpose flour all at once and whisk vigorously for 2-3 minutes until the mixture turns a pale golden color and smells nutty.
This roux is the foundation of our velvety texture. Watch carefully—if it darkens to tan, you've burned it, and the sauce will taste bitter. The evaporated milk will help prevent this, but keeping the heat gentle is key. Here's the thing—don't rush this step. A properly made roux creates that signature creamy mouthfeel we're after.
🥘 Step 3: Incorporate the Evaporated Milk Gradually
Slowly pour in the 2 cups evaporated milk while whisking constantly to prevent lumps. The mixture will thicken immediately as it comes together into a smooth sauce. Bring the sauce to a gentle simmer and cook for 5-7 minutes, stirring frequently, until it thickens enough to coat the back of a spoon.
If the sauce looks too thick before it reaches that point, whisk in 2-3 tablespoons of the reserved pasta water. The evaporated milk gives us a head start on creaminess, but we still need to control the thickness carefully. Here's where it gets fun—taste the sauce now. It should be rich and slightly tangy, with no floury aftertaste.
🥘 Step 4: Add the Cheese Mixture and Finish
In a separate bowl, combine the 1.5 cups sharp cheddar cheese, 1 cup monterey jack cheese, 0.25 cup parmesan cheese, 0.5 teaspoon freshly ground black pepper, and 0.25 teaspoon dried mustard powder. Grate the cheeses freshly if possible—the pre-shredded kind often contains anti-caking agents that make the sauce grainy.
Temper the cheese mixture by slowly sprinkling it into the hot sauce while whisking vigorously. This gradual addition prevents the cheese from clumping. Once all the cheese is incorporated, stir in the 0.25 cup heavy cream (if using) for that extra luxurious texture. The sauce should now be gloriously smooth and glossy, with a beautiful golden hue.
🍽️ Step 5: Combine and Serve (Baked or Stovetop)
For the stovetop version, gently fold the cooked macaroni into the cheese sauce until every noodle is fully coated. If the sauce is too thick, add more pasta water 1 tablespoon at a time until it reaches a creamy, pourable consistency. The final texture should be like a thick, velvety blanket clinging to each noodle.
For the baked version, transfer the macaroni mixture to a greased 8x8-inch baking dish. Sprinkle the 0.25 cup panko breadcrumbs mixed with 0.5 teaspoon garlic powder evenly over the top. Bake at 375°F for 15-20 minutes until the top is golden brown and bubbly. Let it rest for 5 minutes before serving to allow the top to set slightly.
Pro Tips For Making America'S Test Kitchen Mac And Cheese Recipe With Evaporated Milk
- STOP STIRRING SO SOON: The roux in this recipe needs to cook until it’s a deep, nutty gold—about 3-4 minutes after the flour disappears. I learned this the hard way when I rushed it and ended up with a bland, floury sauce instead of that rich, velvety texture. Let it bubble quietly, and resist the urge to check every 30 seconds.
- GRATE CHEESE FINE (AND USE ALL OF IT): Sharp cheddar loses its edge when grated too coarsely, and clumps won’t melt smoothly. Pulse it in a food processor for a powdery consistency, then mix it into the sauce while it’s still hot—this guarantees every bite gets that gooey, tangy hit. Don’t skimp on the amount either; this isn’t the time to play it safe.
- DON’T DRAIN THE PASTA COMPLETELY: Reserve about 1 cup of pasta water before draining, even if the noodles look dry. The ATK recipe relies on that starchy water to bind the sauce and prevent a dry, gritty texture. If you drain it bone-dry, you’ll be fighting to salvage the dish later—trust me, it’s not worth it.
- USE COLD EVAPORATED MILK: Warm the evaporated milk just enough to dissolve the cheese (about 10 seconds in the microwave), but don’t let it get hot. I was skeptical until I tried it—I thought cold milk would curdle the roux, but it actually keeps the sauce silky and prevents that dreaded "broken" texture. Sounds weird, but it works.
Creative variations of america's test kitchen mac and cheese recipe with evaporated milk
Cheesy Twist
Swap the classic cheddar-Monterey Jack combo for Gruyère and fontina—these European cheeses melt into a luxurious, nutty sauce with a subtle tang. Use 1.5 cups Gruyère and 1 cup fontina instead, and reduce the Parmesan to 0.125 cup to maintain balance.
The Gruyère adds a delicate sweetness that pairs beautifully with the evaporated milk's richness. 🧀
Spicy Kick
For heat lovers, add 1 tablespoon hot sauce (like Cholula or Crystal) or 1 teaspoon cayenne powder to the sauce base before incorporating the cheese. For a smoky twist, stir in ½ teaspoon smoked paprika with the spices.
If baking, sprinkle ½ teaspoon cayenne over the panko topping for extra heat. 🌶️
Veggie-Packed
Add 1 cup roasted butternut squash cubes or ½ cup sautéed mushrooms to the baked version for texture and depth. Toss the veggies with 1 teaspoon olive oil and ½ teaspoon garlic powder before mixing into the macaroni.
Roasted broccoli florets also work beautifully—they hold their shape and add a fresh contrast to the creamy sauce. 🥦
Crispy Top Variations
For the baked version, experiment with different toppings: crushed potato chips (like Kettle Brand salted) for a retro vibe, or toasted breadcrumbs mixed with 1 teaspoon dried parsley for a classic touch.
For extra crunch, press ½ cup panko mixed with 2 tablespoons melted butter onto the top before baking. 🍞
Protein Boost
Turn this into a full meal by folding in ½ lb cooked bacon crumbles or ½ cup shredded rotisserie chicken after combining the macaroni and sauce. For a vegetarian option, stir in ½ cup white beans (like cannellini) for extra protein and creaminess.
The evaporated milk sauce helps balance the flavors beautifully. 🍗
Quick Stovetop Upgrade
For a faster version, use 2 cups whole milk instead of evaporated milk and add 2 tablespoons cornstarch to the roux. Simmer the sauce longer to achieve the same velvety texture.
If you're short on time, stir in ½ cup sour cream at the end for extra richness without baking. This works perfectly for weeknight dinners! ⏰

Frequently asked questions
Why does evaporated milk make the sauce so velvety?
The evaporated milk's concentrated proteins and natural thickness create a smooth, creamy texture without needing extra thickeners. It also adds subtle sweetness that balances the sharp cheddar. Plus, it reduces the risk of lumps compared to regular milk—this recipe's secret weapon!
Can I make this without a roux?
Yes! For a quick version, whisk 2 tablespoons cornstarch with 2 cups whole milk until dissolved, then heat until thickened. Add cheese and pasta water as usual. The texture won't be quite as rich, but it's still delicious for weeknight meals.
How do I prevent the cheese from clumping?
Temper the cheese by sprinkling it gradually into the hot sauce while whisking vigorously. Never add cold cheese directly to cold sauce. Also, use freshly grated cheese—pre-shredded contains anti-caking agents that cause graininess. Patience here makes all the difference!
Can I make this ahead of time?
Assemble the stovetop version up to 2 days ahead and refrigerate. Reheat gently with a splash of milk to restore creaminess. For baked mac and cheese, refrigerate the unbaked dish for 1 hour before baking to prevent leaks. Both reheat beautifully.
What's the best way to crisp the baked top?
Press the panko topping firmly onto the cheese before baking. For extra browning, broil for 1-2 minutes at the end. A trick I use: Mix 1 teaspoon melted butter into the breadcrumbs before topping—they'll crisp up perfectly every time.
