Ingredients for arby's white cheddar mac and cheese

Sixteen essential ingredients transform humble elbow macaroni into Arby's signature crisp-crowned, cheesy swirl sensation.

The cheese selection is non-negotiable for authentic flavor. Sharp white cheddar with a minimum 4-year aging delivers that signature tang—avoid pre-shredded blends that contain anti-caking agents. For the ultimate texture, Whole Foods Market or specialty cheese shops carry the ideal aged varieties. If using block cheese, grate it yourself for maximum meltability. The heavy cream and butter combination creates that velvety sauce base, so opt for European-style butter (like Plugrá) for superior fat content and flavor. For the breadcrumbs, Japanese-style panko from Trader Joe's provides the perfect light, airy crunch without weighing down the topping.

No sharp white cheddar? Muenster cheese can substitute at half the quantity for a milder profile, though it lacks the signature sharpness. Running low on heavy cream? Half-and-half works in a pinch, though the sauce will be slightly lighter. For the breadcrumb topping, crushed cornflakes add a budget-friendly alternative with similar texture. The garlic powder can be replaced with fresh minced garlic at double the amount, though it burns more easily during toasting. For those avoiding dairy, nutritional yeast adds a cheesy depth to the breadcrumb mix, though it won't replicate the authentic flavor. Always toast your breadcrumbs before seasoning—they should be golden and crisp for that signature crown texture.

Proper storage maximizes this dish's potential. The cheese sauce can be refrigerated for 3-4 days in an airtight container, though it thickens upon reheating—simply add a splash of warm milk to restore creaminess. For the breadcrumb topping, store separately in a sealed container for up to 5 days to maintain maximum crunch. When reheating, cover with a damp paper towel to prevent drying. This dish freezes exceptionally well—portion the sauce and breadcrumbs separately, then combine when ready to serve. For meal prep, I recommend assembling the dish fresh and baking immediately, as the breadcrumbs lose crispness when reheated. The pasta should be cooked al dente and tossed with sauce immediately to prevent clumping.

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

Master the perfect balance of crispy breaded crown and velvety cheese swirls with this precision method.

Bring a large pot of salted water to a rolling boil—it should taste like the sea. Add the 1.5 lbs elbow macaroni and cook until 1 minute before the package's suggested al dente time. This slight undercooking prevents mushiness when mixed with the cheese sauce. Drain the pasta in a colander, reserving 1 cup of starchy pasta water, which we'll use later to adjust the sauce consistency.

While the pasta cooks, I like to test for doneness by tasting a piece—it should have a slight bite but be fully tender. Overcooked pasta absorbs too much sauce, leaving you with dry mac and cheese. Immediately after draining, give the hot pasta a vigorous shake in the colander to separate the strands and prevent clumping.

In a heavy-bottomed saucepan, melt the 0.5 cup unsalted butter over medium heat until it foams. Whisk in the 0.25 cup all-purpose flour and cook for 2 minutes, stirring constantly, until you achieve a golden roux with no raw flour taste. This forms the foundation of our velvety sauce.

Gradually whisk in the 0.5 cup warmed whole milk and 1 cup heavy cream, ensuring no lumps form. Add the 3 cups sharp white cheddar cheese, stirring continuously until fully melted and smooth. Remove from heat and stir in the 1.5 tsp diamond crystal kosher salt and 0.5 tsp ground black pepper. If the sauce is too thick, whisk in reserved pasta water 1 tablespoon at a time until it reaches a luxurious, coatable consistency.

Working quickly, add the drained elbow macaroni to the cheese sauce. Using a wooden spoon or rubber spatula, fold the pasta into the sauce until every strand is fully coated and the mixture reaches 160°F—this ensures perfect texture without scrambling the cheese. The sauce should be thick enough to cling to the pasta but still flow smoothly when stirred.

For those signature Arby's swirls, transfer the mac and cheese to a 9x13-inch baking dish. Using a spoon, create swirling patterns in the dish, dragging the spoon through the mixture to create ribbons and peaks. This step is what gives the dish its iconic presentation and ensures even baking.

In a medium bowl, combine the 1.5 cups panko breadcrumbs, 1 tbsp granulated garlic powder, 0.25 cup freshly grated parmesan cheese, 2 tbsp extra-virgin olive oil, 1 tsp diamond crystal kosher salt, and 0.25 tsp ground black pepper. Mix thoroughly with your hands until the breadcrumbs are evenly coated and the mixture resembles coarse sand.

Spread the breadcrumb mixture evenly over the swirled mac and cheese, pressing down gently to adhere. Use the back of a spoon to create an even, ¼-inch thick layer across the entire surface. This creates the signature crispy crown that contrasts perfectly with the creamy interior.

Preheat your oven to 375°F. Place the baking dish on the center rack and bake for 20-25 minutes until the breadcrumb topping is deep golden brown and the edges are bubbling. The internal temperature should reach 165°F—this ensures both the crown is crispy and the cheese remains creamy.

Let the mac and cheese rest for 5 minutes before serving. This resting period allows the breadcrumbs to crisp further and the cheese to set slightly, preventing a runny mess. Serve immediately with a side of pickles or a simple green salad to complement the rich, cheesy flavors.

Pro cooking tips for great arby's white cheddar mac and cheese

Roux Perfection

The key to that signature creamy texture lies in a properly developed golden roux. Cook your butter and flour over medium heat for exactly 2 minutes, stirring constantly—don't walk away! A light golden color means you've achieved the perfect balance between flavor development and smoothness.

I use a heavy-bottomed saucepan like All-Clad to prevent burning. If your roux darkens too quickly, reduce the heat immediately to medium-low. 🌡️

Cheese Melting Magic

Sharp white cheddar must melt completely for that authentic Arby's texture. Add the cheese to your warm sauce in small batches, whisking vigorously between additions. Remove from heat for the final stir to prevent scorching.

I've found that 4-year aged cheese from specialty shops melts more smoothly than store-bought varieties. If you see any lumps, strain the sauce through a fine-mesh sieve for ultra-smooth perfection.

Pasta Water Secret

Never throw away that starchy pasta water! It's liquid gold for adjusting sauce consistency. After draining your pasta, reserve 1 cup of that cloudy water. If your sauce thickens too much during cooking, add pasta water 1 tablespoon at a time until it reaches that perfect coatable consistency.

The starch acts as a natural thickener and binder, creating those signature swirls that cling to every noodle. 💫

Swirl Technique

Creating those iconic Arby's swirls takes practice but makes all the difference. Use a long-handled spoon to drag the mac and cheese through the dish in overlapping strokes. Start from the center and work outward, creating ribbons that peak slightly in the middle.

Think of it like painting with your food—each stroke should be smooth and continuous. This technique not only looks impressive but ensures even baking throughout.

Breadcrumb Crisp Control

For that restaurant-quality crispy crown, toast your breadcrumb mixture in the oven for 3-5 minutes before adding it to the mac and cheese. This pre-toasting step ensures maximum crunch that survives baking.

Press the breadcrumbs firmly onto the cheese surface using the back of a spoon—this creates that perfect ¼-inch thick layer that becomes irresistibly crispy. A light spray of olive oil before baking helps achieve that deep golden color. 🔥

Resting Period

Never skip the 5-minute resting period after baking! This crucial step allows the breadcrumbs to crisp further and the cheese to set slightly, preventing a runny mess. During this time, the residual heat continues cooking the surface while the interior maintains its creamy perfection.

I like to tent the dish loosely with foil to keep the breadcrumbs crisp while the cheese stays warm. Serve immediately for that restaurant-fresh experience.
