Baked Mac and Cheese Recipe America's Test Kitchen: Crispy Top, Gooey Pull-Apart Precision

This America's Test Kitchen baked mac and cheese delivers the crispy top and gooey pull-apart texture that makes it legendary. I've tested countless versions, and their method—starting with a proper roux and baking in a cast-iron skillet—is what finally cracked the code for restaurant-quality results at home.

The secret lies in precise timing and technique that transforms ordinary mac and cheese into something extraordinary.

What sets this recipe apart is the foolproof technique that ensures a golden-brown crust while keeping the interior creamy and perfectly melted. America's Test Kitchen developed this method after extensive testing, and it's the only version I trust now.

No more soggy tops or grainy cheese—just a dish that's crispy on the outside, tender on the inside, and impossible to resist pulling apart.

The process begins with cooking the pasta al dente, then mixing it with a rich, velvety cheese sauce made from sharp cheddar, Gruyère, and cream cheese. The sauce gets its stability from a proper roux, which prevents separation even when reheated.

After layering everything in a skillet and topping with breadcrumbs, it bakes until the edges are crispy and the cheese pulls away cleanly from the sides.

This isn't just mac and cheese—it's a showstopping side dish that elevates any meal, whether served alongside roasted chicken or as a hearty vegetarian main. The crispy top adds a satisfying crunch that contrasts perfectly with the creamy cheese filling.

Ready in about 45 minutes, this recipe delivers professional-quality results with simple kitchen tools.

The cheese selection is non-negotiable for that signature pull-apart texture. Sharp white cheddar provides the tangy backbone, while aged Gruyère adds nutty depth—look for blocks labeled 12+ months aged. Penzeys Spices carries excellent options if your local market lacks these varieties. For the butter, Plugrá or European-style unsalted melts more smoothly than American brands. The flour matters too: Diamond Crystal kosher salt has a finer grain than Morton's, which affects roux texture. Pre-shredded cheese contains anti-caking agents that prevent proper melting, so grating your own is worth the effort.

No sharp cheddar? Pepper jack or smoked Gouda add alternative depth, though texture will differ slightly. Substituting Gruyère with Comté or Emmental works in a pinch, but the flavor profile shifts. The cream cheese can be omitted entirely if you prefer a lighter texture, though it adds critical creaminess. For the mustard, Dijon-style provides the right balance of tang—yellow mustard lacks depth. The panko should be lightly toasted before adding to prevent a soggy top, and if unavailable, regular breadcrumbs mixed with 1 tsp cornstarch replicate the crispiness. All cheeses must be shredded freshly to prevent moisture loss during baking.

Store pre-shredded cheese in airtight containers with parchment paper between layers to prevent clumping. The dry pasta keeps indefinitely, while butter and cheese should be used within 6 months for optimal flavor. Once assembled, this bakes best immediately, but you can refrigerate the unbaked skillet for up to 24 hours—just add 5-10 minutes to baking time. Leftovers reheat beautifully in a 350°F oven for 10-15 minutes until bubbly. For make-ahead convenience, portion the cheese sauce separately and assemble just before baking—this prevents a watery texture from the pasta absorbing too much moisture.

Step-by-step instructions for america's Test Kitchen baked mac and cheese

Mastering this recipe delivers the perfect balance of crispy crust and gooey interior every time.

Bring a large pot of water to a rolling boil and add 12 oz elbow macaroni. Cook until 1 minute shy of package directions for al dente texture—this ensures it finishes cooking in the oven without becoming mushy. Reserve 1 cup pasta water before draining, as we'll use it later to adjust the sauce consistency.

I always taste-test a piece at this stage by biting into it—it should offer slight resistance but still feel tender. Drain thoroughly in a colander and return to the pot to prevent drying out. The pasta water is crucial for creating the ideal sauce texture, so don't skip reserving it.

In a large skillet over medium heat, melt the 0.5 cup unsalted butter until foaming. Add the 0.5 cup all-purpose flour all at once and whisk vigorously for 1-2 minutes until the mixture forms a smooth, pale roux with no floury taste. This step is critical for developing flavor and thickening the sauce properly.

Gradually whisk in the 1.5 cups whole milk, 1 tbsp yellow mustard, and 0.75 tsp kosher salt until completely smooth. Remove from heat and stir in the 2 cups sharp white cheddar, 1 cup gruyère, and 4 oz cream cheese until fully melted and creamy. The sauce should be thick enough to coat the back of a spoon but still flow smoothly.

Transfer the cooked macaroni to a large mixing bowl and pour the cheese sauce over it. Using a rubber spatula, gently fold everything together until the pasta is completely coated and the sauce is evenly distributed. The mixture should be thick but still pourable—if it's too stiff, add 1-2 tablespoons reserved pasta water to loosen it.

Season generously with 0.5 tsp freshly ground black pepper and taste to adjust saltiness. The cheese combination should provide enough saltiness, but you may need to add a pinch more salt depending on your preference. This is where the flavors meld together, so take your time to ensure perfect balance.

Preheat your oven to 375°F and grease a 9x13-inch baking dish with 1 tbsp extra-virgin olive oil. Transfer the macaroni mixture to the prepared dish and spread it evenly into a ½-inch thick layer. The even distribution is key for consistent baking.

In a small bowl, combine the 0.5 cup panko breadcrumbs with 1 tbsp melted butter (reserved from the roux). Sprinkle this mixture evenly over the top of the macaroni, pressing down gently to ensure good contact. Bake for 25-30 minutes until the top is deep golden brown and the edges are bubbling.

Remove from the oven and let the macaroni rest for 10-15 minutes before serving. This resting period allows the cheese to set slightly and the flavors to meld together, resulting in that perfect pull-apart texture. The dish should be bubbly in the center with a crispy, golden-brown crust on top.

Serve immediately with a side salad or steamed vegetables. The contrast between the crispy top and gooey interior is what makes this recipe truly exceptional. Each bite should deliver that perfect combination of textures and rich, cheesy flavor that defines America's Test Kitchen's signature baked mac and cheese.

Health benefits of this dish

Comfort Food Nutrition

This baked mac and cheese delivers 15-20 grams of protein per serving—thanks to the cheese blend and elbow macaroni—making it a surprisingly satisfying dish for muscle maintenance. The Gruyère and cheddar provide calcium (about 25% of your daily value per serving) and phosphorus, essential for bone health.

I always pair this with a side salad to balance the richness while keeping those nutrients coming. 💪

Carbs with Purpose

The 12 oz elbow macaroni gives you 45 grams of complex carbohydrates per serving, fueling energy without the blood sugar spikes of refined white pasta. Using whole wheat pasta (if you prefer) bumps fiber to 4 grams per serving while maintaining that creamy texture.

My daughter Lily loves this version because it keeps her energized for hours after school. The key is cooking it al dente—overcooking turns it mushy and loses that satisfying bite.

Cheese Benefits

The Gruyère and sharp cheddar combination isn't just about flavor—it delivers vitamin A (for vision and immunity) and conjugated linoleic acid (CLA), a fatty acid linked to reduced inflammation. The cream cheese adds riboflavin (B2), which supports energy metabolism.

I always opt for full-fat cheeses here because they melt more smoothly and provide satiety—low-fat versions often separate or taste bland. The mustard in the sauce also adds a touch of vitamin C for antioxidant benefits.

Sneaky Veggies Option

For a nutrient boost, I sometimes stir in ½ cup steamed cauliflower or butternut squash into the macaroni before baking. The texture blends perfectly, adding vitamin C, potassium, and fiber without altering the dish's creamy profile.

Lily calls it "cheesy camouflage," and she'll eat three servings! The squash version works especially well in fall when I roast it alongside the mac and cheese. 💛

Balanced Meal Builder

This dish shines as a side or light main when paired with roasted vegetables (like Brussels sprouts or green beans) or a simple arugula salad. The crispy top adds satisfying crunch, while the cheese provides healthy fats that help stabilize blood sugar.

I often serve it at family dinners because it's the one dish everyone requests seconds of—even my husband Tom, who usually avoids carbs. The secret is portion control: aim for 1-1.5 cups per serving to keep calories in check while maximizing flavor.
