About this recipe
You know that one dish at the potluck that disappears before everything else? This is it. Southern baked mac and cheese isn't just regular boxed pasta. It uses a rich custard base made with eggs and evaporated milk to hold all that gooey cheddar together. That custard sets up perfectly in the oven. It gives you those clean, perfectly set slices while staying unbelievably creamy on the inside. Plus, the top gets golden and slightly crispy (the absolute best part of the whole pan). You're going to want to save this recipe for your next Sunday dinner.
Ingredients
Mac and cheese
- 1 lb elbow macaroni
- 4 tbsp unsalted butter (melted)
- 2 cups sharp cheddar cheese (shredded)
- 1 cup Colby Jack cheese (shredded)
- 1 cup whole milk
- 1 cup evaporated milk
- 2 large eggs
- 1/2 cup sour cream
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1/2 tsp paprika
- 1/2 tsp garlic powder
Topping
- 1 cup sharp cheddar cheese (shredded)
- 1/4 tsp paprika (optional)
Equipment
Baking dish
Large pot
Colander
Mixing bowl
Whisk
Instructions
Cook the macaroni
Preheat the oven to 350°F (175°C). Cook the macaroni in well-salted water just until al dente. You want it a little firm because it will soak up liquid and keep cooking in the oven.
Mix the custard
In a large bowl, whisk together the whole milk, evaporated milk, eggs, sour cream, melted butter, salt, pepper, paprika, and garlic powder. Make sure the eggs are fully beaten into the milk so you get a smooth, creamy base without any streaks.
Add pasta and cheese
Fold the cooked macaroni, sharp cheddar, and Colby Jack directly into the wet ingredients. Stir it up well so every single noodle is coated in that creamy mixture.
Transfer to baking dish
Spread the cheesy pasta mixture into a greased 9x13-inch baking dish. Top it evenly with the remaining cheddar cheese and a light sprinkle of paprika for color.
Bake
Bake for about 30 to 35 minutes. You'll know it's ready when the edges are bubbling and the cheesy top has a beautiful golden-brown crust.
Rest and serve
Pull it out of the oven and let it rest for 10 minutes. This resting time is non-negotiable—it helps the custard set up so the mac and cheese slices nicely instead of pooling on your plate.
Common Mistakes to Avoid
Overcooking the pasta
If you boil the macaroni until it's completely soft, it will turn into mush in the oven. Always pull it when it's still slightly firm.
Tips
- Cook the pasta just al dente. The macaroni will continue to soften as it bakes, and overcooked noodles ruin the texture.
- Shred the cheese yourself off the block. Freshly shredded cheese melts so much smoother than pre-shredded bags (which are coated in anti-caking powder).
- Let the pan rest before serving. Resting helps the creamy custard layers settle, making it way easier to scoop.
Substitutions
- Monterey Jack, mild cheddar, gouda, or mozzarella can replace part of the cheese if you want a different flavor profile.
- Add a pinch of cayenne pepper, a dash of hot sauce, or swap in pepper jack if you want some extra heat.
- Replace part of the whole milk with half-and-half for an even richer, thicker texture.
Storage
Refrigerator
Store leftovers in an airtight container in the fridge for up to 3 days.
Reheating
Reheat gently in the microwave or oven until hot. Add a quick splash of milk before heating to bring that creamy texture back to life.
Freezer
You can freeze sturdy baked portions for up to 2 months. Thaw completely in the fridge before reheating.

FAQ
What makes Southern baked mac and cheese different?
Southern baked mac and cheese relies on a custard base—usually eggs and milk—that bakes right into the pasta. It gives it a denser, creamier texture compared to a stovetop roux-based cheese sauce.
Can I make this ahead of time?
Yep! Assemble everything in your baking dish, cover it tightly, and keep it in the fridge. When you're ready, just bake it (you might need to add an extra 5-10 minutes if it's going in cold).
Why is my baked mac and cheese dry?
It usually happens if you over-bake it or don't use enough liquid. Pull it from the oven when it's just set—it will keep firming up as it cools on the counter.
