When a pan of macaroni comes out of the oven, the top can look ready before the middle has finished setting. That’s the moment I watch most closely: the cheese should be golden, while the custard underneath still has a little softness. Southern Baked Mac and Cheese is baked until the center reaches 160°F, then rested so it settles into tender, creamy portions instead of spilling across the plate.
This version has the comforting contrast I want from a baked macaroni dish: a browned cheese top and noodles tucked into a savory egg-and-milk custard. I layer the macaroni with cheddar and Monterey Jack rather than stirring all the cheese into the custard, so there’s cheese throughout and a generous layer on top. It’s a straightforward, hearty casserole that serves eight and belongs on the table while the top is still warm.
Kitchen Note
Stop boiling the macaroni two minutes before the package time is up. It has more time in the oven, and starting with pasta that still has a little bite keeps the finished casserole from turning soft.
Save this Southern Baked Mac and Cheese for a golden-topped casserole with cheddar and Monterey Jack in every layer.
Why This Baked Mac Uses Custard Instead of Cheese Sauce
A stovetop macaroni and cheese gets its creaminess from a sauce that coats the noodles before serving. This casserole takes a different route: eggs, evaporated milk, and whole milk are whisked together, then poured over the layered pasta and cheese. As it bakes, the eggs help the mixture set around the macaroni, giving each serving a cohesive, tender texture rather than a pool of loose sauce.
Evaporated milk brings more body than regular milk alone, while whole milk loosens the mixture enough to pour through the layers. The eggs are part of the structure, not just a richness boost, so leaving them out changes how firmly the casserole sets. Whisk the custard until the eggs are fully blended before pouring; streaks of egg white won’t distribute evenly through the dish.
The layered assembly also gives the custard room to flow between the noodles while keeping the cheese in distinct, melty pockets. It’s a different texture from a smooth stovetop sauce, and that’s exactly what makes this baked version satisfying to serve warm from the dish.
What the Cheddar, Monterey Jack, and Elbows Bring to the Pan
- Sharp cheddar and Monterey Jack — Sharp cheddar gives the layers a pronounced cheese flavor, while Monterey Jack melts smoothly alongside it. Grate both from a block for an even, loose mixture that’s easy to layer; freshly grated cheese is the better choice here than a bag of pre-shredded cheese.
- Elbow macaroni — The curves and hollow centers catch custard and small bits of melted cheese. Use ordinary elbow macaroni for the familiar texture, and drain it well so excess water doesn’t thin the custard in the baking dish.
- Unsalted butter — Tossing the drained pasta with melted butter helps coat the noodles before assembly. Unsalted butter also keeps the salt level in your hands, since the pasta water and custard are seasoned separately.
- Paprika and black pepper — These season the custard without taking over the cheese. Ground paprika is all you need; there’s no special variety required for the gentle color and warm background note.
Getting the Pasta and Custard Into the Oven at the Right Texture
Boil the Elbows Just Short of Tender
Heat the oven to 350°F and coat a 9×13-inch baking dish with nonstick cooking spray. Bring a large pot of water to a boil, add 1 tablespoon of the kosher salt, then cook the macaroni for two minutes less than the package directions. Drain it well and toss it with the melted butter. If the noodles already feel fully soft in the pot, they’ll have less structure left for the oven.
Whisk a Smooth, Even Custard
In a large bowl, whisk the eggs with the evaporated milk and whole milk. Add the remaining 1 teaspoon of kosher salt, the black pepper, and paprika, then keep whisking until the mixture looks uniform. Check the bottom of the bowl for any egg that hasn’t blended in. An evenly mixed custard distributes its seasoning throughout the casserole.
Layer the Cheese, Pour, and Bake
Combine the cheddar and Monterey Jack, then set aside 1 1/2 cups for the top. Layer half the buttered macaroni in the prepared dish, scatter over half of the remaining cheese, and repeat with the rest of the macaroni and cheese. Pour the custard evenly over the layers, then finish with the reserved cheese. Bake for 35 to 45 minutes, until the center reaches 160°F and the top is golden; rest the dish for 10 minutes before serving.
Two Simple Ways to Adapt This Mac and Cheese
Give the cheese layer a little heat
Replace the Monterey Jack with the same amount of pepper Jack and grate it fresh. It keeps the mild, melty character of the original pairing but adds a noticeable chile kick; the sharp cheddar still anchors the cheese flavor.
Make it with gluten-free elbows
Use 1 pound of gluten-free elbow macaroni in place of the regular pasta, and cook it for two minutes less than its package directions before draining and buttering. Gluten-free pasta can soften quickly, so use the package timing for that specific brand rather than the timing for wheat pasta.
Storage and Reheating
- Refrigerator: Store leftovers covered for 3 to 4 days. The pasta will absorb more custard as it sits, so it won’t be quite as soft and creamy as it was fresh from the oven.
- Freezer: Freeze individual portions in airtight containers for up to 2 months. Thaw them overnight in the refrigerator; the custard may be a little less smooth after freezing.
- Reheating: Warm portions covered in a 325°F oven until the center reaches 165°F. Keep the cover on while reheating so the edges don’t dry out before the middle is hot.
