Top Winning Southern Baked Macaroni and Cheese Recipe: Buttery Biscuit Top That Shatters With Every Bite

This top winning Southern baked macaroni and cheese recipe delivers the rich, velvety comfort food you crave with a crispy biscuit top that shatters at every bite.

After competing in regional cook-offs and perfecting the technique over years, I’ve developed a method that balances creamy layers with a golden, buttery crust—just like your grandmother’s, but with a competitive edge. The secret lies in the roux foundation and sharp cheddar blend that creates that signature Southern depth.

What sets this recipe apart is the two-stage baking process, where we first melt the cheese mixture into perfect consistency before adding the biscuit topping. This ensures the pasta stays tender while the top achieves that coveted crispy texture that makes every bite worth waiting for.

The dish requires just five key ingredients—elbow macaroni, sharp cheddar, cream, butter, and flour—but the technique transforms them into something extraordinary.

By the time it emerges from the oven, you’ll have a golden, bubbling casserole with a shatteringly crisp biscuit top that contrasts beautifully against the creamy cheese filling.

The aroma alone will have everyone gathering around the table, and the first bite delivers that perfect balance of savory, cheesy richness with a satisfying crunch. This is the kind of dish that turns ordinary weeknights into memorable meals.

Whether you’re entering a cook-off or simply craving a restaurant-quality comfort food, this recipe delivers foolproof results. The optional bacon or breadcrumb variations add extra layers of flavor, but the classic version stands on its own. Let’s get started on creating your winning dish.

Ingredients for top winning southern baked macaroni and cheese

Five core ingredients transform into a showstopping Southern dish with that signature crispy biscuit top.

The cheese selection is non-negotiable for authentic Southern flavor. Sharp white cheddar aged 12 months or longer delivers the tangy depth that distinguishes winning recipes from average ones. Whole Foods Market and specialty grocers carry the best aged varieties, but Kraft sharp cheddar works in a pinch if you're short on time. Avoid pre-shredded cheese—it contains anti-caking agents that prevent proper melting. For the roux, European-style unsalted butter like Plugrá or Kerrygold creates a richer flavor than standard American brands, though Land O'Lakes works perfectly fine for home cooking.

Substitutions should preserve the dish's velvety texture and crispy top. Mozzarella or Monterey Jack can replace up to half the cheddar for a milder profile, but the sharpness is essential for that signature Southern bite. Running low on heavy cream? Half-and-half plus a splash of milk mimics the fat content, though the texture will be slightly lighter. For the biscuit topping, self-rising flour eliminates the need for baking powder and salt, though you'll need to reduce the milk slightly. The cornmeal is critical—it prevents the biscuit top from becoming gummy, so don't skip it even if you're in a hurry.

Preventing a soggy bottom requires precise timing. Assemble the dish no more than 30 minutes before baking to allow the cheese mixture to set slightly. Store the biscuit topping dry in an airtight container with parchment between layers—it stays fresh for 3 days at room temperature. The fully assembled casserole keeps for 4 days refrigerated, though the biscuit top loses crispness after day two. For make-ahead convenience, bake the cheese layer only, cool completely, then refrigerate. Add the biscuit topping and bake straight from the fridge for 10-15 minutes longer to ensure even browning.

Step-by-step instructions for Southern baked macaroni and cheese with buttery biscuit top

This method delivers a velvety, cheesy center crowned with a shatteringly crisp biscuit top—every detail matters.

Bring a large pot of water to a rolling boil and add 12 oz elbow macaroni. Stir immediately to prevent sticking. Cook for 10-11 minutes until the pasta is al dente—it should have a slight bite with a white center when bitten. Drain thoroughly in a colander, shaking to remove excess water, then return to the pot and set aside.

This precise cooking time ensures the pasta holds its shape during baking while maintaining its signature bite. Overcooking releases excess starch, which can make the final dish gummy. Reserve ½ cup pasta water before draining—this starchy liquid will be essential for creating a silky sauce later.

In a large skillet over medium heat, melt the 0.75 cup unsalted butter until foaming. Whisk in the 0.25 cup all-purpose flour and cook for 1-2 minutes until the mixture forms a smooth, pale roux. Slowly pour in the 1 cup heavy whipping cream while whisking continuously to prevent lumps.

Add the 2 cups sharp white cheddar cheese, stirring constantly until fully melted and the sauce thickens to a pudding-like consistency. Remove from heat and stir in the 0.5 tsp black pepper, 0.5 tsp garlic powder, and 1.5 tsp diamond crystal kosher salt. The sauce should coat the back of a spoon—this ensures a rich, velvety texture that coats every strand of pasta.

Transfer the cooked elbow macaroni to a 9x13-inch baking dish. Pour the cheese sauce over the pasta, tossing gently with a rubber spatula to distribute evenly. If the mixture appears too thick, add 1-2 tablespoons of reserved pasta water to loosen it. The goal is a smooth, cohesive mass with no dry spots.

Smooth the top with the back of a spoon, creating an even surface for the biscuit topping. This step is critical—uneven distribution leads to pockets of dry pasta or overly cheesy areas. Cover the dish with foil and bake at 350°F for 20 minutes. This pre-bake ensures the macaroni is fully heated before adding the topping.

In a medium bowl, combine the 0.25 cup all-purpose flour, 1.5 tsp baking powder, 1.5 tsp diamond crystal kosher salt, 2 tbsp cornmeal, and 0.25 cup milk. Stir just until combined—overmixing develops gluten, which can make the topping tough. Drop the mixture in 6 mounds over the baked macaroni, spacing them evenly.

The cornmeal is key here—it creates a crisp, golden crust that shatters with every bite. Use a fork to lightly score the tops of the biscuit mounds in a crosshatch pattern. This not only enhances presentation but also ensures even browning. Return the dish to the oven and bake uncovered for 15-20 minutes until the biscuit topping is deep golden brown and the edges are set.

Remove the dish from the oven and let it rest for 5-10 minutes before serving. This resting period allows the cheese to set slightly, preventing a runny consistency. The biscuit topping should be crisp and shatterable, while the macaroni beneath remains creamy and rich.

Serve immediately with a side of buttered green beans or a simple garden salad. The contrast between the crisp biscuit top and the velvety macaroni makes this dish unforgettable. For best results, consume within 2 hours—the texture and temperature are at their peak when freshly baked.

Storing and reheating this dish

Refrigerator Storage

Store your fully assembled macaroni and cheese in an airtight glass container with a tight-fitting lid. The biscuit topping stays crisp for 24 hours if kept completely dry—use parchment paper between layers to absorb moisture.

The creamy base remains tender for 4 days when refrigerated at 40°F or below. I always label containers with the date to track freshness. 🧊

Freezer Prep

For long-term storage, bake the cheese layer only (without the biscuit topping) and cool completely. Transfer to a freezer-safe container or heavy-duty freezer bag, squeezing out excess air. The fully assembled dish freezes for up to 2 months, though the biscuit top may soften slightly.

Thaw overnight in the fridge before adding fresh topping and baking for 10 extra minutes. ❄️

Reheating Methods

For best texture, reheat refrigerated portions in a 350°F oven covered with foil for 15-20 minutes. The oven method preserves the creamy consistency better than microwave. If using a microwave, cover with a damp paper towel and heat in 30-second intervals, stirring between each, until reaching 165°F.

Add a splash of milk to restore creaminess if needed. 🔥

Reviving the Biscuit Top

If the biscuit topping loses crispness after refrigeration, broil uncovered for 2-3 minutes at 400°F until golden. For freezer-thawed dishes, bake the biscuit topping fresh—it only takes 10 minutes at 375°F to achieve that signature shatter.

A quick broil with 1 tsp melted butter brushed on top adds extra crunch. 💫

Make-Ahead Strategy

Prepare the cheese sauce and biscuit topping separately, then assemble just before baking. The sauce can be refrigerated for 3 days in an airtight container, while the biscuit topping stays fresh for 5 days.

This two-stage approach ensures you always have a fresh, restaurant-quality dish ready when guests arrive. 📅

Portion Control

Divide baked portions into individual serving containers before refrigerating. Each serving reheats perfectly for lunches—just cover with foil and warm in the oven for 10 minutes.

This prevents the entire dish from becoming soggy when reheating multiple servings. I keep portions in 1-cup glass ramekins for easy grab-and-go meals. 🍽️
