3. Step-By-Step Instructions

This classic baked mac and cheese follows a simple but powerful method: cook pasta, mix cheeses, prepare custard, combine, and bake.

Optional Add-Ons / Variations

Preparation Steps

  1. Preheat oven to 350°F (175°C).
  2. Cook macaroni in salted water until just shy of al dente (it continues cooking in the oven).
  3. Drain and immediately toss with butter to prevent sticking.
  4. Shred all cheeses (avoid pre-shredded; they contain anti-caking agents).
  5. In a large bowl, whisk eggs, milk, heavy cream, salt, pepper, paprika, and mustard powder.
Preparation Steps

Cooking Steps

  1. In a baking dish, layer half the macaroni evenly.
  2. Sprinkle half the shredded cheeses on top.
  3. Add the remaining macaroni and sprinkle the rest of the cheeses.
  4. Pour the custard mixture slowly over the layered pasta.
  5. Gently shake the dish to distribute liquid evenly.
  6. Optional: add more cheddar or breadcrumbs on top.
  7. Bake for 30–40 minutes until the center is set and the top is golden.
  8. Let it rest for 10 minutes before serving — this helps it firm up while staying creamy inside.

Serving Suggestions

Southern baked mac and cheese pairs beautifully with:

  • Fried chicken
  • BBQ ribs
  • Baked chicken

4. Tips, Substitutions & Notes

Pro Tips for Better Results

  • Always shred your cheese fresh — it melts much better.
  • Under-cook the pasta so it doesn’t turn mushy in the oven.
  • Don’t skip the eggs — they are key to the Southern creamy texture.
  • Let the dish rest before serving for perfect slices.

Common Mistakes to Avoid

Ingredient Substitutions

  • Use half-and-half instead of heavy cream.
  • Swap cheddar for Gouda or Monterey Jack.
  • Replace paprika with smoked paprika for deeper flavor.
  • Use lactose-free milk if needed.

Texture, Flavor, or Health Variations

  • Add cream cheese for extra creaminess.
  • Use whole-wheat pasta for more fiber.
  • Add chopped spinach or broccoli for a veggie boost.
  • Make it spicy with jalapeños or Cajun seasoning.

5. Storage & Reheating

Refrigeration

  • Store in an airtight container for 3–4 days.
  • Reheat with a splash of milk to restore creaminess.

Freezing

  • Freeze portions for up to 2 months.
  • Thaw overnight before reheating.

Reheating

  • Oven: Reheat at 300°F with foil on top for 10–15 minutes.
