Ingredients for old fashioned southern baked mac and cheese
Pantry staples plus a few key ingredients for that signature Southern melt and crunch.
| Ingredient | Amount | Notes |
|---|---|---|
| Elbow Macaroni 🍝 | 1 ½ lbs | Medium or elbow shape preferred |
| Sharp Cheddar Cheese 🧀 | 3 cups | Shredded, extra-sharp preferred |
| Unsalted Butter 🧈 | ¾ cup | Cold, cut into small cubes |
| Whole Milk 🥛 | 2 cups | Full-fat for creaminess |
| All-Purpose Flour 🌾 | ¼ cup | For roux, sifted if lumpy |
| Mustard Powder 🌶️ | 1 tsp | For smoky depth |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For subtle garlic flavor |
| Panko Breadcrumbs 🍞 | 1 cup | For crispy topping |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For breadcrumb topping |
| Dried Parsley 🌿 | 1 tbsp | For garnish, chopped |
That sharp cheddar is non-negotiable—Kraft or Cabot are solid choices, but if you can find sharp white cheddar from a specialty store, it takes this to the next level. The butter should be cold when you start the roux, otherwise you'll end up with a greasy mess. I always grab my elbow macaroni from Kroger—it's the same brand my grandma used, and it holds up perfectly. For the breadcrumbs, Panko is a must—it stays crispy even after baking. If you can't find it, toast regular breadcrumbs in the oven first for extra crunch.
No sharp cheddar? Monterey Jack or pepper jack works in a pinch, but the flavor won't be the same. Running low on butter? Olive oil works at half the amount, but it'll change the flavor slightly. The mustard powder is key for that smoky Southern taste—don't skip it. For the breadcrumb topping, you can add a pinch of paprika if you want extra color. Fresh parsley is ideal, but dried works fine if that's what you've got. The milk can be whole or 2%—just don't use skim, or the sauce won't be as creamy.
This reheats beautifully—just cover with foil and warm in the oven for 15-20 minutes at 350°F. Keeps in the fridge for 4-5 days, though I've never had leftovers last that long. For holiday gatherings, I double the recipe—it's always gone by dessert time. Store any extras in an airtight container, and the breadcrumb topping stays crispy if you press plastic wrap directly on top before sealing.
Why You'll Love This Recipe
- No-Fuss Stovetop Start: I swear by the roux here—just butter, flour, and milk simmered until thick enough to coat the back of a spoon. No fancy techniques, just a pot, a whisk, and 10 minutes of hands-off time while the cheese melts into that velvety base.
- Sharp Cheddar Magic: That first bite of crispy, golden top with the sharp cheddar pulling through? It’s the kind of flavor that makes you pause mid-fork. The milk keeps it creamy without being heavy, and the cheddar’s tang cuts through the richness perfectly.
- Potluck Hero: Between us, this is my go-to for gatherings—easy to double, travels well, and even holds up in a cooler. Serve it as a side at church dinners, a main for game day, or just because someone’s craving comfort food. (Yes, even on a Tuesday night.)
- Budget-Friendly Leftovers: A box of elbow mac, a block of cheddar, and a bag of flour stretch farther than you’d think. The leftovers reheat beautifully—just a splash of milk to loosen it up—and my kids still beg for seconds, even after three days.
Step-by-step instructions for old-fashioned Southern baked mac and cheese
Here's how to make a rich, creamy mac and cheese with a golden, crispy breadcrumb crown.
Cook the Elbow Macaroni Al Dente
Bring a large pot of water to a rolling boil and add 1.5 lbs elbow macaroni. Stir immediately to prevent sticking. Cook for 11-12 minutes until the pasta is al dente—it should have a slight bite but still be tender. Drain the pasta in a colander, but don't rinse it. The starch clinging to the pasta helps create that velvety cheese sauce later.
While the pasta cooks, I like to keep a small bowl nearby to catch any stray noodles that might slip through the colander. This ensures you use every bit of that delicious elbow macaroni. Once drained, give the pasta a quick shake in the colander to break up any clumps, but don't overdo it—you want some texture in your dish.
Make the Creamy Cheddar Sauce
In a large, heavy-bottomed pot, melt 0.75 cup unsalted butter over medium heat. Once the butter has fully melted and starts to foam, whisk in 0.25 cup all-purpose flour to create a roux. Cook the roux for 2-3 minutes until it turns a light golden color and smells nutty—this removes the raw flour taste and thickens the sauce.
Slowly pour in 2 cups whole milk while whisking constantly to prevent lumps from forming. Stir in 1 tsp mustard powder, 1.5 tsp salt, 0.5 tsp black pepper, and 0.5 tsp garlic powder. The mustard powder adds that classic Southern smokiness that sets this recipe apart. Bring the mixture to a gentle simmer and let it cook for 5-7 minutes until it thickens enough to coat the back of a spoon.
Add the Sharp Cheddar Cheese
Lower the heat to low and begin adding 3 cups sharp cheddar cheese, one handful at a time. Stir constantly until each addition is fully melted and smooth. The cheese should create a rich, creamy sauce that coats the back of a spoon. If the mixture seems too thick, add 1-2 tablespoons of pasta water to loosen it. This step is where the magic happens—don't rush it.
Once all the cheese is incorporated, fold in the drained elbow macaroni until every noodle is coated in that luscious, cheesy sauce. Taste and adjust the seasoning if needed—sometimes the sharpness of the cheddar needs a little more salt or pepper to balance it out. Transfer the mac and cheese to a well-greased 9x13-inch baking dish and spread it out evenly.
Prepare the Crispy Breadcrumb Topping
In a small bowl, mix together 1 cup panko breadcrumbs, 2 tbsp extra-virgin olive oil, and 1 tbsp dried parsley. The olive oil helps create a crispy, golden-brown topping instead of a soggy one. Sprinkle this mixture evenly over the top of the mac and cheese, pressing down gently to help it adhere.
Here's the thing—don't skimp on the breadcrumb topping. This is what gives the dish that classic Southern crunch and makes it look like it came straight from a grandma's kitchen. The breadcrumbs should cover the entire surface, leaving no cheese exposed.
Bake Until Golden and Bubbly
Preheat your oven to 375°F. Place the baking dish on the middle rack and bake for 20-25 minutes until the top is golden brown and the edges are bubbling. The breadcrumb topping should be crispy enough to stand up to a gentle poke with your finger—if it gives way too easily, let it bake for another 5 minutes.
When it's done, let the mac and cheese rest for 5-10 minutes before serving. This resting time allows the cheese to set slightly, making it easier to slice and serve. The result should be a creamy, cheesy center with a golden, crispy crown on top—just like your grandma used to make. Serve it warm with a simple green salad or crusty bread to soak up every last bit of that cheesy goodness.
Pro Tips For Making Old Fashioned Southern Baked Mac And Cheese
- Cook pasta al dente: DESCRIPTION: Southern mac and cheese demands slightly undercooked elbows—pull them when the package says "2 minutes early." They’ll finish cooking in the oven, and mushy pasta ruins everything. Trust me, I’ve learned this the hard way after slurping up a batch that turned to glue.
- Grate cheese fresh: DESCRIPTION: Pre-shredded cheese has anti-caking agents that make the sauce grainy. Use a box grater for sharp cheddar, and toss the shreds in 1 tablespoon of flour before mixing—this keeps the cheese suspended in the sauce instead of sinking. (Yes, even if you’re impatient like me.)
- Melt butter slowly: DESCRIPTION: Don’t rush the roux—cook the butter and flour over medium heat for 3–4 minutes until it’s a pale gold, not brown. Burning it once turned my mac into a sad, bitter mess. Stir constantly, and resist the urge to crank the heat.
- Bake uncovered first: DESCRIPTION: Start the mac and cheese in the oven uncovered for 10 minutes. This lets the top crust form before you add foil to melt the cheese—otherwise, you’ll end up with a soggy, uneven mess. (Your future self will thank you.)
Essential equipment for this dish
Heavy-Bottomed Pot
You’ll need a large, heavy-bottomed pot (like a Le Creuset Dutch oven or All-Clad stainless steel) for the roux and cheese sauce. This prevents scorching and ensures even heat distribution.
I’ve ruined more than one batch using thin aluminum pots—the sauce sticks and burns too easily. A 5-6 quart pot works perfectly for this recipe. 🔥
Mixing Tools
Invest in a good whisk (I love the OXO Good Grips) and a wooden spoon for stirring the cheese sauce. The whisk helps prevent lumps when adding milk, while the wooden spoon gently folds in the cheese without breaking the curds.
Avoid metal spoons—they can scratch nonstick pans or react with acidic cheeses over time.
Baking Dish
A 9x13-inch baking dish is essential for even baking and that signature Southern presentation. I recommend Ceramic CorningWare or USA Pan—they distribute heat evenly and handle the high temperatures without warping.
Grease it well with butter or olive oil before adding the mac and cheese to prevent sticking. A well-greased dish ensures easy serving and cleanup.
Measuring Tools
Precision matters in Southern mac and cheese! Use a stainless steel measuring cup set (like Farberware) for accurate measurements of flour, milk, and breadcrumbs. A kitchen scale is optional but helpful for the cheese—3 cups shredded cheddar should weigh about 12-14 ounces.
Don’t eyeball it; the balance of fat and starch is what makes this dish creamy without being greasy.
Breadcrumbs
For the perfect crispy topping, panko breadcrumbs are a must. Brands like Kikkoman or Schar provide that light, airy texture that stays crispy even after baking. If you’re using regular breadcrumbs, toast them in a dry skillet over medium heat for 3-4 minutes until golden.
This step adds extra crunch that makes the dish irresistible. ✨
Optional Extras
Add a fine-mesh sieve for shredding cheese (like Microplane) to avoid clumps, and a pastry brush for greasing the baking dish. A timer keeps track of the baking time, and a spatula helps transfer the hot dish from oven to table.
These small tools make all the difference in achieving that restaurant-quality finish. 💡

Frequently asked questions
Why does this recipe use elbow macaroni instead of other pasta shapes?
Elbow macaroni is the classic choice for Southern baked mac and cheese because its shape holds the creamy cheese sauce perfectly while baking. The nooks and crannies trap the melted cheese, creating that signature gooey texture. Other shapes like penne or rigatoni work too, but elbow macaroni delivers that nostalgic, traditional bite.
Can I make this ahead of time for a holiday gathering?
Assemble the dish completely (including the breadcrumb topping) up to 24 hours ahead and refrigerate uncovered. When ready to bake, let it sit at room temperature for 1 hour before baking at 375°F for 30-35 minutes (covered with foil the first 20 minutes to prevent over-browning). The cheese will still melt beautifully.
What's the secret to getting the perfect crispy breadcrumb topping?
Use panko breadcrumbs and press them gently into the cheese before baking. The olive oil in the topping mixture prevents sogginess, and pressing helps them adhere. For extra crunch, toast the breadcrumbs in a dry skillet for 3-4 minutes before mixing with olive oil. Bake uncovered for the last 5 minutes to crisp them up.
Can I substitute cream cheese for some of the sharp cheddar?
You can replace up to 1 cup of the sharp cheddar with cream cheese for extra creaminess, but don't exceed that amount. The cream cheese adds richness but reduces the signature sharp cheddar flavor. If substituting, reduce the milk by 2 tablespoons to maintain the right texture balance.
Why does my Southern mac and cheese sometimes turn out greasy?
Greasy mac and cheese usually happens from one of three things: using too much butter in the roux, not cooking the roux long enough, or adding cold cheese too quickly. Always cook the roux until it's golden and nutty (2-3 minutes), use the full 3 cups of cheese called for, and let the sauce thicken properly before adding the pasta.
