Ingredients for baked mac and cheese recipe america's test kitchen

Six ingredients transform this classic into America's Test Kitchen's crispy-topped, melty masterpiece.

The cheese trio is non-negotiable for that signature ATK flavor. Gruyère brings nutty depth while sharp cheddar delivers tang, and cream cheese ensures velvety texture. For Gruyère, Whittard of Chelsea or Cowgirl Creamery are top-tier choices—look for aged wheels with vibrant color. Cheddar should be block, not pre-shredded (the anti-caking agents ruin texture), and room temperature makes all the difference when blending. Pro tip: Toast your panko in a dry pan for 2 minutes before topping—this eliminates any moisture that could make your crust soggy.

No Gruyère? Comté or Emmental work in a pinch, though flavor will differ slightly. Pre-shredded cheese? Grated yourself—it melts like a dream. The mustard adds subtle tang that balances richness, but if you're avoiding it, lemon zest at half a teaspoon mimics the brightness. For the roux, butter and flour must cook 5-7 minutes until nutty brown—this builds flavor foundation. Need to substitute milk? Heavy cream at half the quantity gives similar richness. And that olive oil? Don't skip it—it's what makes the breadcrumb crust shatter perfectly.

This masterpiece reheats beautifully—just 10 minutes at 350°F covered with foil. For make-ahead magic, assemble completely (including topping) and refrigerate up to 24 hours before baking. The cheese sauce actually improves overnight as flavors meld. Freezes for 3 months if wrapped tightly in parchment and foil. I always bake an extra cup—leftover portions reheat perfectly for quick lunches or late-night cravings. The secret to restaurant-quality texture? Bake until golden (425°F for 20-25 minutes)—don't peek or poke the top until the very end!

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

Here's the foolproof method for that perfect baked mac and cheese—crispy golden top, creamy melt-in-your-mouth center, every time.

Boil a large pot of well-salted water (it should taste like the ocean) and add the 1.5 lb elbow macaroni. Cook until 1 minute before the package's recommended al dente time—this ensures it finishes cooking in the oven without turning mushy. Drain thoroughly but don't rinse; those starchy strands are essential for binding the sauce.

Here's the thing—undercooking the pasta slightly is crucial. When you mix it with the hot cheese sauce, it'll finish cooking perfectly in the oven. I always taste-test a piece at this stage; it should be firm but with just a hint of resistance when you bite down.

In a large, heavy-bottomed pot, melt the 0.75 cup unsalted butter over medium heat until foaming. Whisk in the 0.5 cup all-purpose flour and cook for 2-3 minutes until the roux turns a pale golden color—this creates the velvety texture we're after. Be patient; rushing this step makes the sauce grainy.

Slowly whisk in the 2 cups whole milk, a ladle at a time, ensuring each addition is fully incorporated before adding more. Bring to a gentle simmer and cook for 5-7 minutes until thickened. Remove from heat and stir in the 2 cups sharp white cheddar cheese, 1 cup gruyère cheese, 8 oz cream cheese, 1 tbsp yellow mustard, 2 minced garlic cloves, 1.5 tsp salt, and 0.5 tsp black pepper. Stir until completely melted and smooth—this is where all the magic happens.

Transfer the drained macaroni to the cheese sauce and gently fold everything together using a wooden spoon or rubber spatula. You want to distribute the sauce evenly without breaking the pasta. The mixture should be thick but still coat the back of the spoon. If it's too thick, add 1-2 tablespoons of hot pasta water to loosen it.

This is the moment that matters: the sauce should be thick enough to cling to the pasta but still have a silky consistency. I like to taste-test here too—it should be rich, cheesy, and just slightly tangy from the mustard. If it needs more salt, add it now; you can't adjust seasoning later.

Transfer the macaroni mixture to a 9x13-inch baking dish and spread it evenly. In a small bowl, combine the 0.5 cup panko breadcrumbs, 1 tbsp extra-virgin olive oil, and 0.25 cup freshly grated parmesan cheese. Sprinkle this mixture evenly over the top, pressing down gently to ensure good contact with the cheese sauce.

Bake at 375°F for 25-30 minutes until the top is deep golden brown and the edges are bubbling. The center should still be slightly jiggly—this indicates the perfect melt. If the top browns too quickly, tent with foil for the last 10 minutes to prevent over-browning.

Remove from the oven and let the mac and cheese rest for 5-10 minutes before serving. This resting period allows the sauce to set slightly, making it easier to slice and serve without losing that creamy consistency. The crispy top will soften just a bit, but it'll still hold its texture beautifully.

Serve immediately with a side of steamed broccoli or a simple green salad. Each bite should deliver that perfect balance of crispy, cheesy goodness—rich, creamy, and just slightly tangy from the mustard. This is the baked mac and cheese America's Test Kitchen would be proud of!

Perfect pairings for these flavors

Crispy Top Secrets

For that signature America's Test Kitchen crispy top, I swear by toasting the panko in a dry skillet for 2 minutes before topping—it eliminates moisture that would otherwise make your crust soggy.

Mix the panko with 1 tbsp extra-virgin olive oil and ¼ cup freshly grated parmesan for extra flavor and adhesion. Press it down firmly so every bite gets that satisfying crunch. 🌟

Classic Side Pairings

A simple steamed broccoli with lemon zest and toasted almonds cuts through the richness perfectly. I always serve it with a crisp green salad—mixed greens, cherry tomatoes, and a light apple cider vinaigrette—to balance the meal.

For a heartier option, roasted Brussels sprouts with bacon crumbles add smoky contrast.

Unexpected Add-Ins

Add ½ cup diced smoked gouda to the cheese blend for a smoky depth, or ½ cup cooked bacon crumbled throughout for salty crunch. For a vegetarian twist, ½ cup roasted butternut squash cubes blend beautifully into the sauce.

I once added ½ cup sautéed mushrooms for an earthy note—it worked surprisingly well!

Beverage Pairings

A crisp Chardonnay from California—like La Crema—complements the creamy richness without overpowering. For beer lovers, a hoppy IPA (like Sierra Nevada Pale Ale) cuts through the fat beautifully. If you prefer something lighter, sparkling apple cider adds a refreshing contrast to the rich flavors. 🍷

Make-Ahead Magic

Assemble the dish completely (even with the topping) and refrigerate for up to 24 hours before baking. The flavors actually deepen overnight, and it bakes just as perfectly.

For gatherings, bake it 30 minutes ahead and keep it warm in a 200°F oven—it reheats beautifully with just 5 minutes of extra baking time.

Unexpected Toppings

After baking, sprinkle crushed red pepper flakes for heat or fresh chives for brightness. A drizzle of hot honey adds sweetness that balances the richness. For a gourmet touch, truffle oil (just ½ teaspoon) elevates the dish to restaurant-quality.

These finishing touches make it feel extra special without overpowering the cheesy goodness. 💛
