Arby's Copycat Mac and Cheese Recipe: Smoky Cheddar Crunch With Pull-Apart Magic

This Arby's copycat mac and cheese recipe delivers the same smoky cheddar crunch and pull-apart magic you crave—without the drive-thru wait. The secret lies in a perfectly balanced cheese sauce with sharp cheddar and a crispy breadcrumb topping that locks in all the melty goodness.

After years of perfecting my own version, I finally cracked the code for that iconic restaurant texture and flavor.

The key to authentic copycat results starts with al dente elbow macaroni and a rich, velvety cheese sauce made with butter, milk, and a blend of cheddar cheeses.

The sauce gets its signature depth from a touch of mustard powder and smoked paprika, while the breadcrumb topping transforms it into a golden, crispy masterpiece. This isn't just mac and cheese—it's a crowd-pleasing appetizer that disappears faster than you can say "extra cheese."

What sets this recipe apart is the combination of tender pasta, creamy sauce, and that irresistible crunch on top—just like the original. The sauce clings perfectly to every noodle, and the breadcrumbs create a satisfying contrast with each bite.

Whether you're feeding a game day crowd or craving comfort food, this version delivers restaurant-quality results in your own kitchen.

Ready in under 45 minutes, this mac and cheese requires minimal prep but maximum flavor. The best part? You can customize it with add-ins like crispy bacon or jalapeños if you want to take it to the next level.

Let's get started on recreating that iconic Arby's experience at home.

Ingredients for arby's mac and cheese copycat

Six ingredients for the cheesy sauce, six more for that iconic crunchy topping.

The cheeses are non-negotiable here. Sharp cheddar gives that tangy kick, while smoked Gouda delivers that signature Arby's smokiness. Grab a block of each and shred it yourself—pre-shredded gets clumpy and lacks that restaurant-quality melt. For the best flavor, look for aged cheddar (6+ months) and natural smoked Gouda. If you're in a hurry, Kraft Natural cheddar and Lundberg Farms smoked Gouda are solid shortcuts. The butter should be cold when you start—this keeps the sauce from breaking.

No smoked Gouda? Substitute extra smoked paprika (½ tsp more) and a little smoked cheddar if you can find it. The mustard powder is key for that signature tang—Dijon mustard powder works best, but regular mustard powder is fine in a pinch. For the breadcrumbs, Panko is a must—it's lighter and crisps up better than regular breadcrumbs. If you're feeling fancy, toast the breadcrumbs in the oven for 5 minutes before adding them to the top. The macaroni should be al dente—undercooked pasta soaks up more sauce, but overcooked turns mushy. Trust me on this one.

This mac and cheese keeps beautifully—3-4 days in the fridge, covered tightly. The breadcrumb topping stays crispy for about 2 days if you reheat it covered, then uncover to crisp again. For game day prep, I make it a day ahead and reheat in a 350°F oven for 15 minutes until bubbly. Freezes well for up to 3 months, but the texture gets a little softer after thawing. If you're making it ahead, hold off on the breadcrumb topping until right before serving—otherwise, it gets soggy.

Step-by-step instructions for Arby's copycat mac and cheese

Here's how to nail that signature smoky cheddar crunch with pull-apart perfection.

Bring a large pot of salted water to a rolling boil. Add the 1.5 lbs elbow macaroni and cook for 1 minute less than the package instructions specify. You want it al dente—when you bite into a piece, it should have a slight bite in the center. Drain the pasta and set it aside, reserving 1 cup of pasta water for later. This starchy water is your secret weapon for creating a silky sauce.

Don't rinse the pasta—those surface starches help the cheese cling beautifully. I like to give the pasta a quick shake in the colander to separate the strands before mixing. This ensures each piece gets coated evenly with the sauce later.

In a large pot, melt the 0.75 cup unsalted butter over medium heat until it's completely liquid. Add the 0.25 cup all-purpose flour and whisk vigorously for 1-2 minutes until the mixture forms a smooth, thick paste called a roux. This step is crucial—don't walk away, or you'll get lumps.

Gradually whisk in the 2.5 cups whole milk over 2-3 minutes, ensuring each addition is fully incorporated before adding more. Once fully combined, stir in the 3 cups sharp cheddar cheese and 1.5 cups smoked gouda cheese, letting them melt completely. You'll know it's ready when the sauce becomes glossy and smooth. Remove from heat and stir in the 1 tsp mustard powder, 1 tsp smoked paprika, 1.5 tsp salt, and 0.5 tsp black pepper.

Add the cooked elbow macaroni to the cheese sauce and stir gently but thoroughly to coat each piece. If the sauce is too thick, add pasta water 1 tablespoon at a time until it reaches a creamy, pourable consistency. You want it thick enough to coat the pasta but still able to flow when you pour it. Taste and adjust seasoning if needed—this is where you'll notice if you need more salt or pepper.

Here's the magic: transfer the mixture to a 9x13-inch baking dish and spread it out evenly. The sauce should be just below the top edge of the dish, leaving room for the breadcrumb topping. This layering creates that signature pull-apart texture you love from Arby's.

In a small bowl, mix the 1.5 cups panko breadcrumbs with the 0.25 cup melted butter and 1 tsp garlic powder until evenly combined. The breadcrumbs should look moist but not wet—just damp enough to hold together when sprinkled. Spread this mixture evenly over the top of the mac and cheese, pressing down gently to ensure good contact with the sauce.

Bake uncovered at 375°F for 20-25 minutes, until the top is deep golden brown and the edges are bubbling. The breadcrumbs should be crispy enough to crunch between your teeth, while the cheese underneath remains creamy and pull-apart. If the top browns too quickly, tent it loosely with foil for the last 5 minutes of baking.

Remove the dish from the oven and let it rest for 5-10 minutes before serving. This resting time allows the cheese to set slightly, making it easier to get that perfect pull-apart texture. The dish will be hot, so handle with care—this is where most people burn themselves trying to get the first bite.

Serve immediately with a side of buttery dinner rolls or a crisp green salad. The contrast of the creamy, smoky mac and cheese with the crispy breadcrumb topping is what makes this copycat recipe so special. Each bite should deliver that perfect balance of cheesy pull and crunchy top—just like the original!

Troubleshooting this dish

Sauce Too Thin?

If your cheese sauce turns out too thin after combining with pasta, don't panic! The fix is simple: remove the baking dish from the oven and let it cool for 5 minutes. The cheese will naturally thicken as it cools.

For immediate results, sprinkle 1 tablespoon cornstarch mixed with 1 tablespoon cold water over the sauce, stir gently, then return to the oven for 5-10 minutes until thickened. This trick works wonders without altering the flavor. 🧂

Breadcrumbs Not Crispy?

The breadcrumb topping is the star of this dish, so if it's not crispy enough, you likely need to adjust baking time or temperature. First, ensure your oven is properly calibrated—most home ovens run 25°F hotter than set.

Bake at 375°F for 25 minutes, then broil for 2-3 minutes at the end for extra crispiness. For extra insurance, toast the panko in a dry skillet over medium heat for 2-3 minutes before mixing with butter. This pre-toasting adds an extra layer of crunch. 🍞

Cheese Not Melting Smoothly?

Uneven cheese melting usually means the sauce wasn't hot enough when added. To fix this, gently reheat the sauce over low heat while stirring constantly until fully melted.

For future attempts, melt the cheese in two batches—first melt 2 cups of cheese into the sauce, then stir in the remaining 2.5 cups off the heat. This gradual approach prevents clumping.

If you're using pre-shredded cheese, pulse it in a food processor for 10 seconds to break up clumps before adding. 🧀

Mac and Cheese Too Dry?

If your mac and cheese ends up dry, the issue is usually overcooking the pasta or insufficient sauce. To salvage it, stir in 2-3 tablespoons of warm milk or pasta water while gently reheating over low heat.

For future attempts, ensure your pasta is cooked to al dente and that the sauce fully coats each noodle. If making ahead, cover tightly with foil to retain moisture during storage. Reheat covered with 1-2 tablespoons of water or milk to restore creaminess. 💧

Lumpy Sauce?

Lumps in your cheese sauce are usually caused by uneven heating or adding cheese too quickly. For immediate fixes, use an immersion blender to smooth out the sauce, or press it through a fine-mesh sieve for a silky texture.

To prevent lumps next time, melt the butter and milk together first, then gradually whisk in the cheese while keeping the mixture over low heat. If you're in a hurry, mix the cheese with a splash of milk before adding it to the sauce.

This pre-mixing trick works wonders! 🥣

Topping Too Soggy?

A soggy breadcrumb topping is the most common issue with copycat mac and cheese. The fix is simple: bake the dish uncovered for the full 20-25 minutes at 375°F, then broil for 1-2 minutes right before serving.

For extra insurance, sprinkle the breadcrumbs directly onto the hot mac and cheese right out of the oven and broil immediately. If reheating leftovers, cover with foil and bake at 350°F for 10 minutes, then uncover and broil for 2 minutes to restore crispiness. 🔥
