Au Bon Pain-style macaroni and cheese delivers that signature triple-layered crunch and velvety sauce we all crave. 🔥 The secret lies in a crispy breadcrumb topping, perfectly melted cheddar blend, and al dente pasta—all baked to golden perfection. This isn’t your childhood casserole; it’s restaurant-quality comfort food you can make at home with simple techniques.
What sets this apart is the layered texture: a crunchy breadcrumb crust on top, creamy cheese sauce throughout, and tender pasta at the base.
I’ve perfected the cheese ratio (sharp cheddar, Gruyère, and cream cheese) to create a sauce that’s rich but not heavy, with just the right amount of tang. The breadcrumbs toast to a perfect golden brown while staying crispy, even after baking.
This dish is ideal for family dinners, potlucks, or when you’re craving that nostalgic mac and cheese flavor. The sauce clings to every noodle, and the breadcrumb topping adds a satisfying crunch with every bite. It’s the kind of meal that disappears faster than you can say “triple-layered.”
Ready to recreate that Au Bon Pain magic at home? The process is simpler than you think—just follow the steps for al dente pasta, the perfect cheese sauce, and that signature crunchy topping. Let’s get started!
Ingredients for au bon pain macaroni and cheese
Sixteen ingredients, three layers of magic—this is your Au Bon Pain moment at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lb | Al dente cooking essential |
| Sharp White Cheddar Cheese 🧀 | 2 cups | Freshly grated from block |
| Gruyère Cheese 🧀 | 1 cup | Aged 12 months minimum |
| Cream Cheese 🧈 | 8 oz | Full-fat for creaminess |
| All-Purpose Flour 🌾 | ½ cup | For roux base |
| Unsalted Butter 🧈 | ½ cup | Cold for roux |
| Whole Milk 🥛 | 1 ½ cups | Warmed for sauce |
| Panko Breadcrumbs 🍞 | 1 ½ cups | Japanese-style for crunch |
| Parmesan Cheese 🧀 | ½ cup | Freshly grated |
| Garlic Cloves 🧄 | 3 cloves | Minced for flavor |
| Yellow Onion 🧅 | 1 whole | Diced fine |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Mustard Powder 🧂 | ¼ tsp | For tangy depth |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For breadcrumb topping |
The cheese blend is where this dish shines. Sharp white cheddar gives that signature tang, while Gruyère adds nutty depth—don't skimp on either. I grab mine from Whole Foods or Wegmans for the best quality. The cream cheese keeps the sauce velvety without being heavy. Pro tip: grate your own cheddar and Gruyère—pre-shredded gets clumpy and lacks flavor. For the pasta, elbow macaroni is classic, but any short pasta shape works. Cook it al dente—it'll finish cooking in the oven.
No sharp cheddar? Extra-sharp cheddar at half the amount works in a pinch, but the flavor won't be the same. Swap Gruyère for Comté if you can find it—similar nutty profile. Running low on cream cheese? Creamy goat cheese adds a tangy twist. The mustard powder is non-negotiable—it cuts through the richness. For the breadcrumb topping, Panko is a must (the good stuff, not the pre-seasoned kind). If you're feeling fancy, toast the breadcrumbs with a pinch of garlic powder before adding them to the top.
This dish reheats beautifully—just cover with foil and bake at 350°F for 15 minutes. The sauce gets even creamier after sitting overnight, so make extra. Store leftovers in the fridge for 4-5 days or freeze for 3 months. I always double the breadcrumb topping—it disappears fast. For serving, a sprinkle of extra Parmesan and fresh parsley makes it look restaurant-worthy. The key to that signature Au Bon Pain crunch? Bake it uncovered for the last 5 minutes—watch those breadcrumbs turn golden!

Step-by-step instructions for triple-layered crunch mac and cheese
This isn't your grandma's mac and cheese—we're building layers of flavor and texture.
🍳 Step 1: Cook the Elbow Macaroni Al Dente
Bring a large pot of salted water to a rolling boil—it should taste like the ocean. Add the 1.5 lb elbow macaroni and cook until 1 minute before the package suggests for al dente (it should have a slight bite). Drain immediately, reserving 1 cup of pasta water. I always taste-test one piece—it should be tender but still have a little resistance when you bite it.
While the pasta cooks, I like to set up my baking dish with a light layer of the 2 cups sharp white cheddar cheese and 1 cup gruyère cheese shaved thinly over the bottom. This creates that signature Au Bon Pain golden crust when we bake. Don't skip this—it's what makes this version special.
🥘 Step 2: Build the Creamy Cheese Sauce
In a large saucepan, melt the 0.5 cup unsalted butter over medium heat until foaming. Whisk in the 0.5 cup all-purpose flour to form a roux—cook for 2-3 minutes until it turns a pale golden color (this removes the raw flour taste). Slowly whisk in the 1.5 cups warmed whole milk until smooth.
Reduce heat to low and stir in the 8 oz cream cheese, 0.5 cup parmesan cheese, 1.5 tsp salt, 0.5 tsp black pepper, and 0.25 tsp mustard powder. Let it simmer for 5 minutes until thickened—it should coat the back of a spoon. If it's too thick, add 1-2 tablespoons of the reserved pasta water. Here's the thing—this sauce needs to be velvety smooth, so strain it through a fine-mesh sieve if needed.
👨🍳 Step 3: Create the Crispy Breadcrumb Topping
While the sauce simmers, prep the breadcrumb topping. In a small bowl, mix the 1.5 cups panko breadcrumbs, 2 tbsp extra-virgin olive oil, 3 minced garlic cloves, and 0.5 tsp black pepper. Spread this evenly on a baking sheet and toast in a 375°F oven for 5-7 minutes until golden brown—watch it closely so it doesn't burn.
For the onion, sauté the 1 whole yellow onion diced fine in 1 tbsp olive oil over medium heat for 5-6 minutes until soft and translucent. This adds sweetness that balances the cheesy richness. Set aside—you'll use it in the next layer.
🥘 Step 4: Assemble the Triple-Layered Masterpiece
Preheat your oven to 375°F. In a 9x13-inch baking dish, spread half of the cooked macaroni evenly over the bottom. Pour half of the cheese sauce over the pasta, then sprinkle half of the sautéed onion. Add the remaining macaroni, then the rest of the sauce and onion. Top with the toasted breadcrumb mixture and press down gently.
Bake uncovered for 20-25 minutes until the top is deep golden brown and bubbly. Here's where patience pays off—if you open the oven early, you'll lose that perfect crust. The edges should pull away slightly from the pan, and the cheese should be melted but not runny. Let it rest for 10 minutes before serving—this helps everything set properly.
Pro Tips For Making Au Bon Pain Macaroni And Cheese
- Melt Cheeses Slowly: Dump all the cheeses into the pot at once and you’ll end up with lumps—trust me, I’ve done it. Instead, whisk in the sharp cheddar first until it’s fully melted, then gradually add the gruyère and cream cheese, stirring constantly. The cream cheese needs time to soften properly, so don’t rush it.
- Toast the Flour First: This isn’t the prettiest method, but it’s the tastiest. Dry-toast the all-purpose flour in a separate pan over medium heat for 1-2 minutes until it smells nutty. Stir it into the butter-milk mixture cold—this adds depth and prevents that chalky aftertaste.
- Cook Pasta Al Dente: The Au Bon Pain version relies on the pasta holding its shape, so don’t overcook. Test a piece at 1 minute before the package’s suggested time—it should have a slight bite. Drain it and immediately toss with a splash of pasta water to keep it from drying out.
- Add a Splash of Milk: The roux in this recipe can get thick fast. If it starts seizing up before the cheeses are fully incorporated, whisk in 1-2 tablespoons of milk (or the reserved pasta water) to loosen it. It’s better than scraping burnt bits off the bottom.
Make-ahead tips for this recipe
Prep Ahead Strategy
Assemble the entire dish—pasta, sauce, and toppings—up to 24 hours ahead in a 9x13-inch baking dish. Cover tightly with aluminum foil and refrigerate. When ready to bake, remove the foil and bake at 375°F for 25-30 minutes until golden and bubbly.
The cold start helps the breadcrumbs crisp up beautifully. 💫
Cheese Sauce Prep
Make the cheese sauce a day ahead and store it in an airtight container in the fridge. Reheat gently over low heat, adding a splash of milk if it thickens too much.
The sauce actually tastes better after resting overnight as the flavors meld together. I often double the recipe for leftovers.
Breadcrumb Toasting
Toast the breadcrumb mixture separately and store it in an airtight container at room temperature for up to 3 days. Keep the garlic and pepper separate until ready to use to prevent sogginess.
When baking, sprinkle fresh toasted breadcrumbs on top just before the final 5 minutes of baking for maximum crunch.
Pasta Pre-Cooking
Cook the pasta al dente and store it in the fridge for up to 2 days in an airtight container. When reheating, add it to the sauce directly in the baking dish—no need to pre-cook again.
The pasta will finish cooking perfectly in the oven while the cheese melts. I always rinse the pasta after cooking to remove excess starch.
Complete Make-Ahead Bake
For ultimate convenience, assemble the entire dish (including breadcrumbs) and refrigerate for up to 24 hours. When ready to serve, bake at 375°F for 35-40 minutes, covered with foil for the first 25 minutes then uncovered for the final 10-15 minutes to crisp the topping.
This method works perfectly for holiday gatherings when you want to focus on serving instead of cooking.
Freezer-Friendly Method
Assemble the dish completely and freeze it in a single layer in a baking dish for up to 3 months. When ready to serve, thaw in the fridge overnight, then bake at 375°F for 40-45 minutes until bubbly and golden.
The texture remains creamy and the breadcrumbs stay crispy when reheated properly. Add a splash of milk when reheating if the sauce looks dry.

Frequently asked questions
Why does this recipe use three different cheeses?
The cheese blend creates the signature Au Bon Pain flavor profile. Sharp white cheddar delivers that tangy punch, Gruyère adds nutty depth, and cream cheese keeps the sauce silky smooth without being heavy. Each cheese plays a role—skip any and you'll miss that restaurant-quality taste.
Can I make this mac and cheese without baking it?
For a stovetop version, mix the cooked pasta with the cheese sauce, then stir in the sautéed onion. Top with toasted breadcrumbs and broil for 3-5 minutes until golden. The texture will be creamier but still have that satisfying crunch.
What's the secret to the perfect breadcrumb topping?
Toast the breadcrumbs separately before adding them to the dish—this ensures maximum crunch. Use Panko (not regular breadcrumbs) and press them gently into the top so they stay in place. Bake uncovered for the last 5 minutes to get that golden, crispy finish.
How do I fix runny cheese sauce?
If your sauce separates or looks too thin, mix 1 tablespoon cornstarch with 1 tablespoon cold water to make a slurry. Stir it into the sauce while heating gently until thickened. Never use flour—it can make the sauce grainy.
Can I add other ingredients like bacon or broccoli?
Yes! Cook 4 oz bacon until crispy and crumble it into the sauce, or stir in 2 cups steamed broccoli florets when assembling. Just reduce the cheese by 0.5 cup to maintain the perfect balance. For extra flavor, try adding a pinch of smoked paprika or cayenne.
