The first thing I watch when this pan comes out of the oven is the edge: it should be bubbling, with a golden layer of cheese across the top. Southern baked mac and cheese has a custardy middle, not a loose cheese sauce, so the noodles need a little room to finish cooking as everything bakes together.

I cook the elbows just short of tender, then stir them into eggs and milk while they’re still hot. The custard coats each noodle, and the cheddar and Monterey Jack melt through it as the casserole bakes. Freshly grating the cheese takes a few extra minutes, but it gives you a smoother melt than the pre-shredded bags.

The top gets its color while the center sets, so I use both the visual cues and a thermometer rather than judging by the crust alone. After a short rest, the slices hold their shape but stay soft in the middle, with a sharp-cheddar bite and a browned, bubbling top.

Kitchen Note

The center temperature is a more dependable cue than color alone. Once it reaches 160°F, let the casserole rest for 10 minutes; that pause helps the custard settle so it scoops cleanly.

Save Southern baked mac and cheese for its golden cheddar top, bubbling edges, and soft custardy center.

Why the Elbows Need to Leave the Pot Before They’re Tender

Macaroni that’s fully tender before it goes into the dish has nowhere to go during baking. It keeps absorbing the egg-and-milk custard in the oven, and that extra cooking can leave the noodles too soft by the time the top is golden. I stop boiling them two minutes before the package timing says they’re done. They should still have a firm bite in the center.

That short head start matters because this casserole bakes long enough for the noodles to finish cooking while the custard sets. It also gives the pasta time to take on some of the seasoned milk mixture instead of turning into a soft layer beneath the cheese. Drain the elbows well before combining them with the custard; water clinging to the pasta dilutes the mixture and works against a firm, creamy set.

Think of the pot of water as the first part of the cooking, not the whole job. Pull the pasta while it still feels a little underdone, and let the oven finish it alongside the cheese and custard.

The Custard and Cheese Have Different Jobs in This Pan

Southern Baked Mac and Cheese with cheesy custard
  • Elbow macaroni — Its curves hold onto the custard and make it easy to serve in a scoop. Use regular dried elbows for the timing and texture described here. If you need a gluten-free version, gluten-free elbows are the closest swap; see the variation below because brands can cook at different speeds.
  • Eggs — The eggs set the milk mixture into a custard around the pasta. They’re doing more than adding richness, so I don’t recommend leaving them out or replacing them with a liquid-only substitute; the finished casserole would lose its structure.
  • Evaporated milk and whole milk — Evaporated milk brings concentrated dairy richness, while whole milk keeps the custard fluid enough to coat the noodles. Both are useful here, and using two kinds of milk gives the baked interior a fuller texture than swapping in only a thinner milk. There isn’t a direct equal-volume replacement that keeps the same balance.
  • Sharp cheddar — This is where the casserole gets its familiar tang and most of its cheese flavor. Buy a block and grate it fresh; freshly grated cheese melts more evenly than bagged shreds. Extra-sharp cheddar works in the same place if you want a more pronounced bite.
  • Monterey Jack — Jack brings a mild, smooth melt that softens the cheddar’s sharper edge. It’s a practical cheese to buy by the block and grate at home. You can replace some of the cheddar with more Jack for a milder result, while keeping the total amount of cheese the same.
  • Dry mustard and paprika — These season the custard without turning it into a strongly spiced dish. The dry mustard gives the cheese a little savory lift; paprika adds gentle warmth and color. Ground spices from an ordinary pantry work well here, so there’s no need to seek out a specialty brand.
  • Butter — Softened butter coats the baking dish so the casserole releases more easily around the edges. A thin, even coating is enough; the butter is for the pan, not part of the custard.

Build the Custard Around Hot, Just-Undercooked Elbows

Boil the pasta to a firm bite

Heat the oven to 350°F and grease a 9×13-inch baking dish with the softened butter. Bring a large pot of water to a boil, add the elbows and the tablespoon of salt, then cook until two minutes shy of the package directions. The pasta should bend but still feel firm when you bite into it. Drain it well so excess cooking water doesn’t thin the custard.

Whisk a smooth, seasoned custard

In a large bowl, whisk the eggs with the evaporated milk and whole milk until the mixture looks even. Add the remaining salt, black pepper, paprika, and dry mustard, whisking until the seasonings are distributed and there are no obvious streaks of egg white. A large bowl gives you room to add the hot pasta without splashing. Have the cheese ready before you combine everything, since the next step works best while the macaroni is hot.

Coat, layer, and bake until set

Add the hot macaroni to the custard and stir until the noodles are coated. Mix in 12 ounces of the cheddar and 4 ounces of the Monterey Jack, then transfer everything to the prepared baking dish. Sprinkle the remaining cheeses evenly over the surface so you get a cheesy top from edge to edge. Bake for 35 to 45 minutes, until the top is golden, the edges bubble, and the center reaches 160°F.

Three Changes That Keep the Casserole’s Character

Make it with gluten-free elbows

Use gluten-free elbow macaroni in place of the regular pasta, and follow its package timing while still stopping two minutes early. Gluten-free noodles can soften quickly, so check them before the timer rather than letting them boil past a firm bite. The custard and cheeses stay the same, though the pasta’s texture may be a little less springy.

Turn up the cheddar flavor

Replace the sharp cheddar with extra-sharp cheddar, keeping the quantity the same. The finished mac and cheese has a stronger, tangier cheese flavor, while Monterey Jack still brings a mild note to the blend. Grate the block yourself for an even melt.

Use cavatappi instead of elbows

Swap in the same quantity of dried cavatappi for a shape with ridges and a larger spiral. Cook it according to its package, stopping two minutes short, then follow the same custard and baking method. The grooves catch the cheese mixture, and the casserole looks a little more substantial on the plate.

Storage and Reheating

  • Refrigerator: Store leftovers in an airtight container for 3 to 4 days. The chilled custard firms up, so the pasta will feel less soft straight from the fridge.
  • Freezer: Freeze cooled portions in airtight containers for up to 2 to 3 months for best quality. Thaw them in the refrigerator; the custard may be a little less smooth after freezing.
  • Reheating: Cover a portion and warm it in a 325°F oven until it reaches 165°F throughout. Uncovered reheating can dry out the top before the middle is hot.

Questions I Get Asked About Southern Baked Mac and Cheese

Can I use pre-shredded cheese?+

You can, but freshly grated cheese gives the casserole a smoother melt. Bagged shreds are coated to keep them from clumping, and that coating can make the cheese feel less cohesive in the custard. For the most even result, grate the blocks just before assembling.

Can I make the casserole ahead?+

You can grate the cheeses and butter the baking dish ahead, but I’d wait to cook the pasta and mix it with the egg-and-milk custard until you’re ready to bake. Once combined, the noodles keep absorbing liquid, which can leave them softer than intended if the assembled dish sits. Bake it after mixing for the best texture.

Can I leave out the dry mustard?+

Yes. The casserole will still set because the eggs and dairy form the custard; it will simply have less of the savory sharpness that dry mustard brings to the cheese. Keep the other seasonings as listed so the flavor stays balanced.

Can I make this without eggs?+

I wouldn’t omit them in this version. The eggs set the milk mixture around the noodles, so without them the center won’t have the same custardy structure. For an egg-free baked macaroni, you’d need a different sauce method rather than a direct swap here.

How do I know the center is cooked through?+

Look for bubbling around the edges and a golden top, then check the middle with an instant-read thermometer. The surface can brown before the custard has finished setting, so color by itself isn’t enough to judge doneness. Let the casserole rest before serving so the center has time to settle.
