Au Bon Pain Mac and Cheese Recipe: Triple-Layered Crunch With Gooey Cheese Streaks

This Au Bon Pain mac and cheese recipe delivers the restaurant’s signature triple-layered crunch and gooey cheese streaks right in your oven. The secret lies in a precise blend of sharp cheddar, a buttery roux, and a crispy breadcrumb topping that locks in moisture while creating that coveted golden crust.

After perfecting this technique through countless test batches, I’ve streamlined it for home cooks—no fancy equipment required, just attention to temperature and timing.

The foundation begins with al dente pasta cooked in salted water, then tossed with a velvety cheese sauce made from a rich roux and a mix of cheddar cheeses. The sauce must coat every noodle completely, creating that signature creamy texture with visible cheese ribbons.

What sets this apart is the layering technique: a crispy breadcrumb topping bakes directly onto the cheese, forming a caramelized crust that contrasts perfectly with the tender pasta beneath.

By the time it emerges from the oven, you’ll have a dish that rivals the original—golden, bubbling, and with that signature crunch that makes every bite satisfying. The cheese sauce remains luscious and stretchy, clinging to each noodle, while the breadcrumb topping adds a delightful textural contrast.

This is comfort food at its finest, elevated by restaurant-quality techniques you can replicate at home.

Serve immediately with a side of garlic bread or a simple green salad to let the mac and cheese take center stage. The key to success? Precision in cooking times and cheese temperatures—don’t skip the broiling step, as it’s what creates that perfect crispy top.

Let’s get started on recreating this iconic dish.

Ingredients for au bon pain mac and cheese

Sixteen ingredients. One iconic dish. The secret's in the layers and timing.

The cheeses are non-negotiable here. Sharp white cheddar gives the signature tang, while extra-sharp cheddar adds depth—both need to be freshly shredded from blocks (pre-shredded gets clumpy). Monterey Jack keeps the sauce creamy. Grab these at Whole Foods or your local specialty cheese shop if possible; the flavor difference is noticeable. For the roux, unsalted butter is key—it should foam but not brown. The milk? Whole milk and heavy cream combo makes this sauce velvety, not watery. Don't skimp on the fat content here.

No sharp cheddar? Pepper jack at half the amount works in a pinch, but the flavor won't be identical. Pre-shredded cheese? Toast it in a dry pan for 2 minutes to remove excess moisture. Running low on panko? Toasted breadcrumbs from a baguette (pulse in food processor) give the same crunch. The garlic and onion powders can be swapped for fresh minced garlic and onion if you prefer, but the powders are more reliable for consistent flavor. And for the love of cheese, don't use powdered milk substitutes—the sauce will curdle.

This dish is all about timing. Cook the pasta 1 minute less than package instructions—it finishes baking in the oven. The cheese sauce should be thick but pourable; if it's too stiff, whisk in 1-2 tbsp milk. Assemble the casserole at least 30 minutes before baking to let flavors meld. Leftovers? 3-4 days refrigerated, but honestly, it's best eaten fresh. For make-ahead, assemble the dish, refrigerate overnight, then bake straight from cold—add 10 minutes to baking time. Worth it for a crowd.

Step-by-step instructions for triple-layered mac and cheese

Here's how to build that iconic Au Bon Pain texture—crispy crust, gooey cheese, and perfect al dente pasta.

Bring a large pot of water to a rolling boil and add the 1.5 lb elbow macaroni. Season generously with 1.5 tsp kosher salt—the water should taste like the sea. Cook until 1 minute before the package suggests al dente (about 11-12 minutes). The pasta should have a slight bite when you taste it.

Drain the pasta in a colander, but don't rinse it—those starches are essential for the sauce to cling. Transfer the hot pasta to a large mixing bowl and set aside. Here's the thing—overcooking pasta ruins everything. You want each bite to have that satisfying resistance.

In a separate large pot, melt the 0.5 cup unsalted butter over medium heat. Once fully melted, whisk in the 0.25 cup all-purpose flour to create a roux. Cook for 1-2 minutes until the mixture bubbles and smells nutty—this removes the raw flour taste.

Gradually whisk in the 2 cups whole milk and 0.5 cup heavy cream, letting each addition absorb completely before adding more. Bring the mixture to a gentle simmer and cook for 5-7 minutes until thickened. Now for the cheese—add the 1.5 cups sharp white cheddar, 1 cup extra-sharp cheddar, and 0.5 cup monterey jack, stirring constantly until fully melted and smooth.

Pour the melted cheese sauce over the hot pasta in the mixing bowl. Add the 1 tsp garlic powder, 1 tsp onion powder, and 0.5 tsp black pepper. Using a wooden spoon or spatula, fold everything together until the pasta is fully coated in the sauce. Taste and adjust seasoning—you might need a pinch more salt.

This is where the magic happens. The residual heat from the pasta will help melt the cheese completely, creating those signature cheese streaks. If the sauce looks too thick, add 1-2 tablespoons of pasta water to loosen it to a creamy consistency that clings beautifully to each noodle.

Preheat your oven to 375°F and grease a 9x13-inch baking dish with 2 tbsp extra-virgin olive oil. Spread half of the macaroni mixture evenly in the bottom of the dish. In a small bowl, mix the 1 cup panko breadcrumbs with the 0.25 cup freshly grated parmesan cheese—this is your crispy topping.

Sprinkle half of the breadcrumb mixture over the first layer of macaroni. Add the remaining macaroni mixture on top, then sprinkle the remaining breadcrumb mixture evenly over the top. Press down gently but firmly—this ensures maximum crispiness when baked.

Bake uncovered for 20-25 minutes until the top is deep golden brown and the edges are crispy. The cheese should be bubbling and pulling away from the sides slightly. If it's browning too quickly, tent loosely with foil for the last 5 minutes to prevent burning.

Let the mac and cheese rest for 10 minutes before serving—this allows the layers to set slightly and makes slicing much easier. The result should be a crispy, crunchy top layer that contrasts perfectly with the creamy, cheesy interior. Serve warm with a side of garlic bread for the ultimate comfort food experience.

Essential equipment for this dish

Essential Baking Dish

You’ll need a 9x13-inch baking dish—preferably made of heavy-gauge aluminum or stainless steel to distribute heat evenly. I recommend a Wilton Professional Baking Pan (about $20) for its durability and even heat conduction.

Avoid dark-colored pans—they can cause uneven browning. Grease it thoroughly with 2 tbsp extra-virgin olive oil before adding the macaroni mixture to prevent sticking. 🧈

Precision Thermometer

A kitchen thermometer is non-negotiable for this recipe. I use a Thermoworks Thermapen ONE ($50) to monitor the oven temperature and ensure it stays at 375°F—fluctuations can ruin the crispy crust.

If your oven runs hot, reduce the temperature to 350°F for more consistent results. A basic instant-read thermometer (like OXO Good Grips, $20) works too, but it’s less precise for long bakes.

Mixing Tools

For the roux and sauce, use a heatproof mixing bowl (I love Le Creuset stoneware bowls) and a wooden spoon or heat-resistant silicone spatula to stir without scratching your pot.

A hand mixer (like KitchenAid KHM5221USB, $100) isn’t essential, but it saves time when whisking in the milk and cheese. For folding the pasta, a large, sturdy spatula (like OXO Good Grips) ensures even coating without breaking noodles.

Breadcrumbs & Cheese Prep

Freshly shredded cheese makes all the difference—use a box grater (like Microplane) for sharp white cheddar and extra-sharp cheddar to avoid clumping. For the breadcrumb topping, panko is ideal, but if you’re using regular breadcrumbs, pulse them in a food processor for a finer texture.

A small mixing bowl (like Pyrex glass) works perfectly for combining panko with Parmesan cheese before topping the mac and cheese.

Oven Rack Position

Place your baking dish on the middle rack of your oven for even heat distribution. If your oven has a broiler, use it for the last 2-3 minutes of baking to achieve that signature golden, crispy crust.

Just watch it closely—broilers can burn quickly! A timer (set on your phone or oven) ensures you don’t overbake, which can turn the top rubbery instead of crunchy. 🕒

Optional: Food Processor

For extra efficiency, a food processor (like Ninja FP101, $50) can quickly pulse stale bread into homemade breadcrumbs.

If you’re making this ahead of time, a large airtight container (like Rubbermaid Brilliance) keeps the assembled mac and cheese fresh in the fridge for up to 24 hours before baking. Just add 10 extra minutes to the baking time if starting from cold.
