Arby's Copycat Mac and Cheese Recipe: Crispy Breadcrumb Crown Over Smoky Cheddar Rivers

Arby's mac and cheese copycat recipe delivers that iconic crispy breadcrumb crown and smoky cheddar rivers you crave. 🔥 The secret lies in a perfectly balanced cheese sauce that's creamy yet tangy, topped with golden, buttery breadcrumbs that stay crunchy until the very last bite.

I've recreated this comfort food staple using simple techniques that guarantee restaurant-quality results at home.

What makes this copycat recipe work is the two-stage cooking process: first, we create a rich, velvety cheese sauce with sharp cheddar and a touch of mustard for depth, then we assemble it in a baking dish and crown it with buttery breadcrumbs that bake until golden and crispy.

The result is a mac and cheese that's foolproof—no clumpy sauce or soggy toppings here.

By the time you pull this out of the oven, you'll have a dish that looks and tastes exactly like the Arby's original: tender pasta swimming in a smooth, slightly tangy cheese sauce, topped with a crispy breadcrumb crown that shatters at every bite.

The aroma alone will have everyone gathering around the table, and the first forkful will have them asking for seconds.

This recipe serves four and comes together in about 45 minutes, making it perfect for weeknight dinners or meal prep. The best part? You can customize it with optional toppings like crispy bacon bits or fresh green onions if you want to put your own spin on this classic.

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

Ingredients for arby's mac and cheese copycat

Four cheeses, two butters, and one secret tangy kick. That's all you need for Arby's magic.

The cheddar is where this dish shines. Sharp white chedddar gives that signature tang, while medium cheddar adds smoky depth. I grab Kraft 2% sharp white from the deli section—it's pre-shredded and melts perfectly (no clumps!). For the medium cheddar, Boar's Head is my go-to, but any good block will work. Pro tip: if your cheddar smells like milk, it's too fresh—let it sit out for 10 minutes to release its full flavor. The Parmesan? Kraft grated is fine here—no need to splurge on a wedge. The mustard is non-negotiable though; French's Dijon gives that signature tang without overpowering.

No sharp cheddar? Colby Jack at half the amount works in a pinch, but it won't be as tangy. Out of panko? Crushed cornflakes are a decent swap, though they won't get as crispy. The milk can be whole or 2%—just don't use skim, or the sauce will break. For the breadcrumb crown, toasted panko (spread on a baking sheet at 350°F for 5 minutes) adds extra crunch. And if you're feeling fancy, add a pinch of smoked paprika to the breadcrumb mix for that Arby's smokiness. The butter? Land O'Lakes unsalted is my standard, but any good brand works.

This reheats beautifully—just cover with foil and bake at 350°F for 15 minutes. The breadcrumb crown stays crispy if you reheat it separately. Keeps for 4 days in the fridge, but honestly, it's gone by day 2. For make-ahead magic, assemble the dish (without baking) up to 24 hours ahead. The sauce will thicken slightly, but a splash of milk brings it back. Freezes for 3 months—just bake straight from frozen, adding 10 minutes to the time. Portion into individual servings before freezing for easy lunches.

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

Here's how to nail that iconic crispy crown and creamy cheese combo every time.

Bring a large pot of water to a rolling boil and add 12 oz elbow macaroni. Stir immediately to prevent sticking. Cook for 2 minutes less than the package directions—you want it slightly underdone since it'll finish cooking in the oven. Drain and set aside, reserving 1 cup of the starchy pasta water.

Here's the thing—overcooked pasta turns mushy in the oven. You'll know it's perfect when you bite into a strand and it has a tiny bit of resistance. That starchy water we reserved? It's liquid gold for creating the creamiest sauce later.

In a large skillet over medium heat, melt 0.5 cup butter until it foams. Whisk in 0.25 cup all-purpose flour and cook for 1-2 minutes until it forms a smooth roux and smells nutty. This is your flavor foundation—don't rush it or you'll get a raw flour taste.

Slowly whisk in 2 cups whole milk and 1 tbsp yellow mustard, letting the mixture thicken between each addition. Stir in 2 cups sharp white cheddar cheese and 1 cup medium cheddar cheese until completely melted. Season with 1.5 tsp salt, 0.5 tsp black pepper, and 0.5 tsp garlic powder. The sauce should be thick but pourable—add a splash of reserved pasta water if needed.

Add the drained macaroni to the skillet and stir until every noodle is fully coated with the creamy cheese sauce. The mixture should look like a thick, glossy river of melted cheddar. Taste and adjust seasoning—you want that perfect balance of sharp cheddar flavor with just a hint of tang from the mustard.

Transfer the entire macaroni and cheese mixture to a greased 9x13-inch baking dish. Spread it out evenly with a spatula, pressing down gently to eliminate air pockets. This ensures even baking and that signature Arby's texture throughout.

In a bowl, mix together 1 cup panko breadcrumbs, 0.25 cup melted butter, and 0.25 cup grated Parmesan cheese until evenly combined. The breadcrumbs should look moist but not wet—if they clump, add a few more panko.

Sprinkle the breadcrumb mixture evenly over the top of the macaroni and cheese, pressing down lightly with your fingers. This creates the perfect crispy crown that's the hallmark of Arby's version. Don't skip pressing—it makes all the difference in texture.

Preheat your oven to 375°F. Bake the macaroni and cheese for 20-25 minutes until the top is deep golden brown and the edges are bubbling. The crown should be crispy enough to hold its shape when you lift it.

Let it rest for 5 minutes before serving—this gives the cheese time to set slightly and makes it easier to cut. The center should still be creamy, with that perfect melt-in-your-mouth texture. Cut into squares and serve immediately while the crown is still crispy and the cheese is gooey.

Wine and beer pairings for this arby's mac and cheese copycat

Creamy Cheese Pairings

For a smooth, velvety mac and cheese experience, opt for a crisp Chardonnay with notes of vanilla and citrus. I love a California Chardonnay like Kim Crawford—its buttery texture mirrors the dish’s richness while the acidity cuts through the cheddar’s sharpness. 🍷

If you prefer something lighter, a Sauvignon Blanc from New Zealand, like Oyster Bay, adds a zesty contrast that brightens the dish’s creamy depth. The grapefruit notes complement the mustard tang in the sauce beautifully.

Bold Beer Options

A honey wheat beer is my go-to pairing—try Blue Moon or Allagash White. The caramel and floral notes enhance the cheddar’s smokiness while the light body prevents the beer from overpowering the dish. 🍺

For beer lovers, a light lager like Miller Lite or Coors Light works surprisingly well. The crisp, clean finish cleanses your palate between bites of the rich, cheesy pasta. Avoid heavy stouts or IPAs—they’ll clash with the delicate balance of flavors.

Unexpected Wine Twists

For a fun twist, try a Pinot Noir with earthy, red fruit notes—Meiomi is a crowd-pleaser. The light tannins won’t overpower the dish, and the berry flavors echo the smoky cheddar. It’s a refreshing change from typical red wine pairings.

If you’re feeling adventurous, a sparkling rosé like Whispering Angel adds a festive touch. The bubbles cut through the richness, making each bite feel lighter and more refreshing. Perfect for a special dinner or holiday gathering!
