The edges of a baked macaroni casserole can turn golden while the middle is still loose, which makes it tempting to pull the dish early. I wait for the center to set, not just the top to brown. That’s what gives this Southern Baked Mac and Cheese its tender, cheesy middle and a top you can scoop through without the custard running across the plate.
This version gets its body from eggs whisked with evaporated milk and whole milk, rather than a stovetop cheese sauce. I layer the cheddar and Monterey Jack between the macaroni, then pour the custard over everything so it settles through the dish as it bakes. The pasta goes into the oven just shy of al dente, leaving room for it to finish cooking in the custard. Once rested, the casserole serves eight with distinct layers of pasta and melted cheese beneath its golden top.
Kitchen Note
Use the softened butter to coat the bottom and all four sides of the baking dish, including the corners. That thin coating helps the baked cheese release cleanly when you serve it.
Save this Southern Baked Mac and Cheese for its layered cheddar and Monterey Jack, custardy center, and golden top.
Why This Mac and Cheese Sets Like a Custard, Not a Cheese Sauce
Eggs change the texture of this casserole. Whisked with evaporated milk and whole milk, they set around the macaroni in the oven, giving each serving enough structure to hold together after a short rest. This isn’t a stovetop cheese sauce that needs to stay fluid; it’s a baked custard with cheese layered through it. Evaporated milk brings more body than whole milk alone, while the whole milk keeps the mixture easy to pour.
The cheese stays in layers instead of being stirred into the custard. Cheddar and Monterey Jack melt between the macaroni, and the last layer of cheddar forms a continuous top. Pour the custard across the whole dish so it can settle through the pasta rather than pooling at one edge. That balance is why the casserole has a tender center without feeling like a bowl of loose sauce. The color of the top is a useful cue, but it can’t tell you whether the center has set.
What the Cheddar, Jack, and Evaporated Milk Each Bring
- Evaporated milk and eggs — Together, they create the custard that holds the pasta in a baked casserole. Use evaporated milk, not sweetened condensed milk; condensed milk is sweetened and would change the dish. Whole milk keeps the mixture pourable, so whisk the eggs and dairy until they look evenly combined before assembling.
- Sharp cheddar — This is the bold, familiar cheese flavor in every layer and on the top. A block that you shred yourself melts more evenly than pre-shredded cheese, which is coated to keep the shreds separate. Pre-shredded cheddar still works if convenience matters more than the smoothest melt.
- Monterey Jack — Jack softens the sharper cheddar with a mild, creamy melt. It’s a good choice when you want a blend without adding another assertive cheese. Keep the shreds fairly even so they scatter through the layers instead of clumping together.
- Elbow macaroni and butter — Elbows hold the layered cheese well, and the butter tossed with the drained pasta helps coat the pieces before they meet the custard. Unsalted butter lets the measured kosher salt do the seasoning work. Paprika and black pepper add gentle warmth without taking over the cheddar.
Build the Layers Before the Custard Goes In
Cook the Elbows Just Short of Tender
Heat the oven to 350°F and grease a 9×13-inch baking dish with the softened butter. Bring 4 quarts of water and 1 tablespoon of kosher salt to a boil in a 6-quart pot, then add the elbow macaroni. Cook it according to the package directions until it’s just shy of al dente; it should still have a little firmness when you bite into it. Drain it well, then toss it with the melted butter while it’s still warm.
Whisk the Milk and Egg Custard
In a medium bowl, whisk the eggs with the evaporated milk and whole milk. Add the remaining salt, black pepper, and paprika, whisking until the seasonings are spread through the mixture. You’re looking for a uniform pale custard, not separate streaks of egg white and yolk. Set the bowl close to the baking dish so it’s ready to pour after the cheese is layered.
Layer the Macaroni and Cheese
Spread half the macaroni in the prepared dish, then scatter over 1 1/2 cups of cheddar and 1/2 cup of Monterey Jack. Add the remaining macaroni, followed by another 1 1/2 cups of cheddar and the rest of the Jack. Finish with the remaining cheddar across the top, spreading it toward the corners for an even cover. Pour the custard evenly over the whole dish so no section is left dry.
Bake Until the Center Sets
Bake for 35 to 45 minutes, until the top is golden brown and the center registers 160°F. The top may brown before the middle is ready, so use an instant-read thermometer to check the center rather than relying on color alone. Once it reaches temperature, take the casserole out and let it rest for 10 minutes before serving. That pause gives the custard time to settle into a scoopable texture.
Simple Swaps That Keep the Casserole’s Character
Use Gluten-Free Elbow Pasta
Replace the regular elbows with the same amount of gluten-free elbow macaroni. Cook it according to its package directions, stopping just shy of al dente before draining and continuing with the same layers. Gluten-free pasta can soften faster in the oven, so begin checking the casserole at the early end of the bake time.
Make It All Cheddar
Use sharp cheddar in place of the Monterey Jack, keeping the same total cheese amount and layering pattern. The result has a more pronounced cheddar bite and loses the Jack’s mild, creamy contrast. This is an easy swap when you’d rather buy one kind of cheese.
Choose a Milder Cheddar
Swap medium cheddar for the sharp cheddar if you want a gentler cheese flavor. Keep the same amount and layering; the custard and Monterey Jack still provide the same baked structure and creamy contrast. The finished casserole will taste less tangy, with a softer cheddar presence.
Storage and Reheating
- Refrigerator: Store leftovers covered for 3 to 4 days. The pasta firms up as it chills, so the casserole will be denser straight from the refrigerator.
- Freezer: Freeze fully cooled portions in airtight containers for up to 2 months. The custard may be a little less smooth after thawing, but the portions are still handy for reheating.
- Reheating: Thaw frozen portions in the refrigerator, then reheat covered in a 350°F oven until the center reaches 165°F. A microwave works for individual portions; heat in short intervals and stop once the middle is hot, since prolonged heating can dry the macaroni.
