Southern Baked Mac and Cheese

Creamy, cheesy, and baked to golden perfection—this Southern-style mac and cheese is pure comfort in a casserole dish. With a velvety roux-based sauce made from whole milk, heavy cream, and three kinds of melted cheese, it’s rich without being greasy. Then there’s the secret: eggs, which give the center a silky custard texture that holds its shape when sliced. Topped with crispy panko or extra cheddar, it’s the ultimate side dish for holidays, weeknights, or any time you need a taste of home.


Why You’ll Love This Recipe

This isn’t just another mac and cheese—it’s a Southern kitchen heirloom. Inspired by church potlucks, Sunday dinners, and holiday feasts, this version skips the stovetop-only method and goes straight into the oven for depth of flavor and a perfect finish. The blend of sharp cheddar, creamy Colby Jack, and stretchy mozzarella creates layers of flavor, while garlic, mustard, and paprika add warmth and complexity.

Perfect for:

  • Thanksgiving, Easter, and Christmas dinners
  • Feeding a crowd (or just yourself for days)
  • Fans of custardy, not soupy, baked mac & cheese
  • Making memories with every bite

🧀 “I made this for my family reunion,” said one home cook. “My cousin asked if I’d been cooking all day—but I mixed it up while the turkey rested!”


Ingredients

For the Pasta & Custard Base

  • 16 oz (450g) elbow macaroni (uncooked)
  • 2 large eggs, beaten (key for creamy texture)

For the Roux & Sauce

  • 4 tbsp (½ stick / 56g) unsalted butter
  • ¼ cup (30g) all-purpose flour
  • 4 cups (950ml) whole milk, warmed (not cold!)
  • 1 cup (240ml) heavy cream

For Seasoning

  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1 tsp dry mustard (or 1 tbsp Dijon)
  • ½ tsp paprika (smoked or sweet)
  • Salt and freshly ground black pepper, to taste

For Cheesy Goodness

  • 4 cups (400g) sharp cheddar cheese, shredded (divided)
  • 2 cups (200g) Colby Jack cheese, shredded (divided)
  • 1 cup (100g) mozzarella cheese, shredded (divided)

For the Crispy Top (Optional)

  • ½ cup (45g) panko breadcrumbs
  • 2 tbsp melted butter

Step-by-Step Instructions

1. Preheat Oven & Prep Pan

  • Preheat oven to 350°F (175°C).
  • Grease a 9×13-inch baking dish or large casserole with butter or nonstick spray.

2. Cook the Pasta

  • Bring a large pot of salted water to a boil.
  • Cook macaroni until al dente (~1 minute less than package directs).
  • Drain and set aside—do not rinse.
  • 3. Make the Roux

    In a large saucepan over medium heat:

    • Melt butter.
    • Whisk in flour and cook 1–2 minutes, stirring constantly—this removes raw flour taste.

    4. Build the Creamy Sauce

    • Gradually whisk in warmed milk and heavy cream, a little at a time, until smooth.
    • Cook 8–10 minutes, stirring often, until thickened enough to coat the back of a spoon.

    ❗ Don’t rush—low and slow prevents lumps.


    5. Season & Melt Cheese

    • Stir in garlic powder, onion powder, mustard, paprika, salt, and pepper.
    • Remove from heat.
    • Stir in 3 cups cheddar, 1½ cups Colby Jack, and ½ cup mozzarella until fully melted and smooth.

    6. Temper the Eggs

    In a small bowl:

    • Add beaten eggs.
    • Slowly pour in ½ cup hot cheese sauce, whisking constantly—this warms the eggs without scrambling them.
    • Pour egg mixture back into the saucepot and stir well.

    ✅ Tempering tip: Prevents curdling.


    7. Combine with Pasta

    • Add cooked macaroni to the cheese sauce.
    • Stir gently until every noodle is coated.

    8. Assemble & Top

    • Transfer mixture to prepared baking dish.
    • Sprinkle top with:
      • Remaining 1 cup cheddar
      • Remaining ½ cup Colby Jack
      • Remaining ½ cup mozzarella

    ✅ Optional crunch: Mix panko with 2 tbsp melted butter and sprinkle over cheese.


    9. Bake to Golden Perfection

    • Bake 30–35 minutes, uncovered, until:
      • Edges are bubbly
      • Top is golden brown
      • Center is hot and slightly firm

    ✅ Tent with foil after 20 mins if browning too fast.

    • Let rest 10–15 minutes before serving—this helps it hold shape when scooped.
    • Serve warm, straight from the dish.

    Pair with:

    • Fried chicken or pulled pork
    • Collard greens or green beans
    • Cornbread or garlic toast

    ✅ Leftovers? Reheat gently in the oven—the custard only gets better!


    You Must Know

    • Use freshly grated cheese —pre-shredded contains anti-caking agents that make sauce grainy.
    • Warm the milk —cold liquid can shock the roux and cause separation.
    • Eggs = silky texture —don’t skip them; they bind and enrich.
    • Tastes better the next day! Flavors deepen overnight.
    • Freezer-friendly —cool completely and freeze before or after baking.

    Storage Tips

    • Store leftovers in an airtight container in the fridge for up to 5 days.
    • Reheat in oven at 350°F for 15–20 minutes (best texture). Microwave works but may soften edges.
    • Freeze for up to 3 months —thaw overnight before reheating.
