Atlanta Mac and Cheese Recipe: Crispy Buttermilk Biscuit Top, Gooey Cheddar Layers

This Atlanta mac and cheese recipe delivers the ultimate Southern comfort food experience—crispy buttermilk biscuit topping that shatters over gooey cheddar layers so rich they practically melt in your mouth.

The secret lies in the technique: baking the pasta first for a sturdy base, then piling on that velvety cheese sauce, and finally crowning it with a golden, crackly biscuit topping that's impossible to resist.

I've perfected this version after years of testing, and it's the one that finally convinced even the biggest mac-and-cheese skeptics in my family.

The magic happens in the layers—extra-sharp cheddar blended with cream cheese for that signature Southern tang, then baked until bubbly and golden. The buttermilk biscuit topping isn't just a garnish; it's the star, providing a crispy contrast that cuts through the richness while adding a subtle sweetness.

This isn't your average mac and cheese; it's a restaurant-quality dish that tastes like it came straight from a Southern kitchen, complete with that perfect balance of textures and flavors.

What makes this recipe truly special is how it captures the soul of Atlanta-style mac and cheese—the kind that's worth the wait, the kind that disappears faster than you can say "hot sauce."

The biscuit topping stays crispy even after cutting, while the cheese underneath remains creamy and stretchy, with just the right amount of heat from a touch of cayenne. It's the kind of dish that transforms a simple weeknight dinner into a celebratory meal, no matter the occasion.

Serve it as a main course with a side salad or collard greens, or turn it into a crowd-pleasing casserole for gatherings. The best part? Every bite delivers that perfect harmony of crispy, creamy, and cheesy—just like the best Southern cookouts.

Let's get started on making this iconic dish at home.

Ingredients for atlanta mac and cheese

Six layers of Southern cheesy perfection—crispy topping, gooey center, and that signature tang.

The cheddar is non-negotiable—extra-sharp is the secret to that bold, tangy flavor. Publix or Whole Foods carry the best block cheddar, but any sharp cheddar works if you can't find those. I always buy a whole block and grate it myself; pre-shredded gets clumpy and lacks that fresh-from-the-grater texture. The cream cheese adds that velvety richness, but don't skimp on the quality—Philadelphia brand is my go-to. For the biscuit topping, King Arthur flour gives the best rise, but any all-purpose works in a pinch. That said, don't use self-rising flour—it's a game-changer for crispiness.

No sharp cheddar? Monterey Jack or pepper jack in a pinch, but it won't be the same. Running low on buttermilk? Mix 1 tbsp vinegar or lemon juice with 1 cup milk—it's a Southern classic trick. The cayenne is optional but adds that signature kick; if you're sensitive to heat, cut it to 1/8 tsp. For the biscuit topping, baking powder is crucial—don't substitute baking soda. And if you're feeling fancy, add 1/4 cup grated Parmesan to the topping mix for extra depth. The chicken broth adds richness, but half-and-half works too if you're out.

This dish is all about layers—bake the pasta first for structure, then assemble and bake again for that perfect set. The biscuit topping stays crispy for 3-4 days if stored in an airtight container, but honestly? It disappears faster than that. Freeze portions of the cheese sauce separately for up to 3 months—just bake the pasta fresh when you're ready to serve. Pro tip: Make the biscuit topping dry mix ahead and refrigerate it; it's stable for 5 days that way. Leftovers? Reheat in a 350°F oven for 15 minutes—microwaving makes the topping soggy.

Step-by-step instructions for Atlanta mac and cheese with crispy biscuit top

Here's how to build layers of gooey cheddar and a golden biscuit crust that'll have everyone begging for seconds.

Bring a large pot of water to a rolling boil and add 1.5 lbs elbow macaroni. Cook for 1 minute less than package instructions—you want it al dente because it'll finish cooking in the oven. Reserve 1 cup of the pasta water before draining, then drain the noodles completely.

While the pasta cooks, preheat your oven to 375°F. The high heat will help create that signature crispy biscuit top later. I like to keep the reserved pasta water handy—it's the secret weapon for keeping our cheese sauce silky smooth.

In a large bowl, combine the drained macaroni with 2 cups shredded extra-sharp cheddar cheese, 8 oz cream cheese, 1 cup heavy whipping cream, and 1 cup chicken broth. Mix gently but thoroughly until the cheese melts completely and coats the pasta evenly.

Here's where the magic happens: the cream cheese adds that rich, velvety texture while the chicken broth keeps everything moist. If the mixture looks too thick, add 2-3 tablespoons of that reserved pasta water to loosen it. The sauce should be creamy but still coat the back of a spoon.

In a separate bowl, whisk together 2.5 cups all-purpose flour, 2 tbsp baking powder, 1 tbsp garlic powder, 0.25 tsp cayenne pepper, 0.5 tsp black pepper, and 1 tbsp granulated sugar. Cut in 0.5 cup cold salted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces.

Add 1 whole large egg and 0.5 cup buttermilk to the dry ingredients and stir just until combined. Don't overmix—you want a thick, shaggy dough. The buttermilk adds tenderness while the baking powder ensures that perfect lift in the biscuit top. Keep this mixture cold until ready to use.

Transfer the cheesy macaroni mixture to a greased 9x13-inch baking dish. Spread it out evenly, creating a smooth surface. This is your base layer—make sure it's level so the biscuit top cooks evenly.

Drop spoonfuls of the biscuit dough over the top of the macaroni, spacing them about 1 inch apart. Gently press down to create a continuous layer, but don't overwork it. Bake at 375°F for 25-30 minutes until the biscuit top is deep golden brown and the edges are set.

Let the mac and cheese rest for 5-10 minutes before serving. This gives the biscuit top time to set properly and prevents it from falling apart when you cut into it. The internal temperature should reach 165°F at the center.

Cut into squares and serve immediately. You'll want that biscuit top to be warm and crispy—each bite should deliver that perfect contrast of creamy, cheesy macaroni with a golden, slightly crunchy biscuit crust. Trust me, it's worth the wait!

Creative variations of this dish

Southern BBQ Twist

Transform your mac and cheese into a true Southern showstopper by adding ½ cup BBQ sauce (I love Sweet Baby Ray's) to the cheese mixture before baking. Stir it in with the chicken broth for a smoky-sweet depth that pairs perfectly with the biscuit topping.

Top with crumbled bacon and pickled red onions for extra texture and tang. This version screams "tailgate food" and disappears even faster than the classic. 🔥

Spicy Hot Honey Drizzle

For a sweet-and-spicy kick, drizzle the finished mac and cheese with a mix of 2 tbsp hot honey (like Chimichurri or Honey Bee Hot Honey) and 1 tbsp sriracha right before serving.

The honey softens the biscuit topping slightly while the cayenne adds a slow-building heat that balances the richness. I like to serve this with a side of cool ranch dressing for dipping. 🌶️

Breakfast Mac and Cheese

Turn this into a brunch sensation by adding ½ cup cooked breakfast sausage (like Johnsonville Original) to the cheese mixture and topping with fried eggs and chives before baking. The eggs add a runny yolk element that cuts through the cheesiness, while the sausage brings a smoky depth.

Bake covered for 15 minutes first, then uncovered for 10 minutes to crisp the biscuit topping. Serve with hot sauce on the side. 🍳

Vegetarian Veggie Load

Make this dish veggie-friendly by stirring in 1 cup roasted butternut squash and ½ cup sautéed mushrooms with the macaroni. For extra protein, fold in ½ cup crumbled feta cheese along with the sharp cheddar.

The squash adds natural sweetness that balances the tangy biscuit topping, while the mushrooms bring an umami depth. Garnish with toasted pecans for crunch and fresh thyme for brightness. 🥕

Bacon and Cheddar Casserole

For a heartier version, layer ½ lb crispy bacon (cooked and crumbled) into the cheese mixture and top with an extra ¼ cup shredded cheddar before adding the biscuit topping. The bacon adds a smoky richness that pairs perfectly with the buttery biscuit crust.
