Gather your ingredients for a classic Southern mac and cheese recipe.

Core Ingredients

A true Southern mac and cheese recipe needs quality staples.

• 1 lb elbow macaroni
• 1/2 cup unsalted butter
• 3 large eggs
• 1 can (12 oz) evaporated milk
• 1/2 cup whole milk or sour cream
• Salt and black pepper

The Cheese Blend

The secret lies in mixing multiple cheeses for maximum flavor and that perfect melt.

Optional Flavor Boosters

Add these for a more complex taste.

• 1 tsp dry mustard powder
• 1/4 tsp garlic powder
• 1 bay leaf (remove before baking)
• Hot sauce (few dashes)
• Smoked paprika for topping

Pantry Checklist

Before starting your authentic Southern mac and cheese verify you have these items.

• 9x13 baking dish
• Large pot for boiling pasta
• Mixing bowls
• Whisk
• Aluminum foil

Quality ingredients make or break this dish. Splurge on good sharp cheddar for the best results.

Boil the elbow macaroni until just tender.

Water Volume and Salt

Use a large pot. Fill with 4-6 quarts of water per pound of pasta. This prevents sticking and clumping. Salt the water generously. It should taste like the sea. This is your only chance to season the pasta itself.

Cooking Time for Al Dente

Bring water to a rolling boil. Add pasta and stir immediately. Cook for 1-2 minutes less than the package directs for "al dente." The pasta will finish cooking in the oven's custard. Overcooking leads to a mushy final casserole.

Draining and Rinsing

Drain pasta thoroughly in a colander. Do not rinse. Rinsing removes surface starch needed to bind the cheese sauce. Return hot pasta directly to the empty pot or a large bowl. The residual heat helps it absorb the custard later.

Common Mistakes to Avoid

• Using a small pot. Crowding causes sticky pasta.
• Skipping the salt. Pasta tastes bland without it.
• Cooking to full doneness. It will become overcooked during baking.
• Rinsing with cold water. This washes away the starch glue.
• Draining poorly. Excess water dilutes the cheese sauce.

Why Undercook the Pasta?

The Southern baked mac and cheese custard is a liquid. The pasta sits in it for 25-40 minutes. The residual heat and moisture from the baking dish continue to soften the noodles. Starting with al dente pasta ensures a perfect final texture—tender but still with a slight bite, never mushy.

Whisk eggs milk and shredded cheese to form the custard base.

Temper the eggs

Crack three large eggs into a mixing bowl.

Beat the eggs vigorously until yolks and whites blend completely.

Pour one can of evaporated milk and half a cup of whole milk into a saucepan.

Warm the milks gently on the stove but do not boil them.

Slowly stream the warm milk mixture into the beaten eggs while whisking constantly.

This tempering process prevents scrambled eggs in your Southern baked mac and cheese.

Mix the custard base

Add melted butter to the milk and egg mixture.

Whisk in dry mustard black pepper and salt.

This liquid forms the rich custard that sets the casserole.

• Ensure the mixture is completely smooth.
• Do not add cold milk straight from the fridge.
• Keep whisking to incorporate air for a lighter texture.

Select and shred the cheese

Buy cheese in blocks rather than pre-shredded bags.

Pre-shredded cheese contains anti-caking powders that ruin the melt.

Grate sharp cheddar and mild cheddar using the large holes on a box grater.

Toss the hot drained pasta with the grated cheeses.

Pour the wet custard base directly over the cheesy noodles.

Stir everything together off the heat until the pasta coats evenly.

Custard ratio guide

Bake the assembled casserole until the top gets golden.

Prep the baking dish

Coat a 9x13 inch baking dish with butter or nonstick spray.

Pour the cheesy pasta and custard mixture into the dish evenly.

Spread it out with a spatula so it sits level.

Sprinkle extra shredded cheese across the top for a crispy crust.

Two-stage baking method

Cover the dish tightly with aluminum foil.

This traps steam and lets the egg custard set without drying out.

Bake at 350 degrees for the first 25 minutes covered.

Remove the foil carefully to avoid steam burns.

Continue baking uncovered for 15-20 more minutes.

The top should turn golden brown and bubble at the edges.

Baking time and temperature reference

Signs it is done

• Edges are bubbling and lightly browned.
• Center is set not jiggly when you gently shake the dish.
• Top cheese layer is golden with crispy spots.
• A knife inserted in the center comes out clean.

Broiler option

Want a darker crust with extra crunch?

Switch the oven to broil for the final 2-3 minutes.

Watch it constantly. Broil goes from perfect to burnt in seconds.

Common baking mistakes

• Skipping the foil cover. Dries out the top before the center sets.
• Cutting into it immediately. Causes the casserole to fall apart and look soupy.
• Using a glass dish without adjusting temp. Reduce oven by 25 degrees for glass bakeware.

Serve this rich comfort food hot at your next potluck.

Transporting the casserole

Use a dish with a tight-fitting lid or heavy-duty foil.

Wrap the entire dish in a thick towel then place in a cooler.

For longer trips use a insulated food carrier.

The goal is to retain heat without drying the top.

Maintaining serving temperature

If the potluck has a warming oven use it.

Set your dish in a water bath pan with hot water.

This gentle steam heat prevents the edges from drying.

Never leave the casserole at room temperature over two hours.

Presentation and garnishes

Bring the dish straight from the oven if possible.

The bubbling golden top is part of the appeal.

Garnish simply with fresh parsley or extra black pepper.

• Paprika adds color but little flavor
• Crispy bacon bits are a popular add-on
• A drizzle of hot sauce on the side pleases many

Reheating instructions

If reheating is needed cover with foil.

Warm at 300 degrees until hot throughout.

Uncover for the last 10 minutes to crisp the top.

Microwave individual portions only as it makes the pasta rubbery.

Pairing suggestions

This rich dish balances with simple sides.

• Mixed green salad with vinaigrette
• Steamed green beans
• Collard greens
• Cornbread

Storage and leftovers

Cool leftovers quickly spread thin on a sheet pan.

Refrigerate within two hours in an airtight container.

Reheat portions in a skillet with a splash of milk.

Leftover baked mac and cheese keeps 3-4 days.
