Step 1

Preheat the oven to 375 degrees F. Bring a large pot of salted water to a boil.

Step 2

Cook the macaroni according to the package directions until 3 minutes less than fully cooked. Drain and rinse under cold water until cooled; drain well. Add the cooked pasta back to the pot.

Step 3

Put the eggs, heavy cream, Cajun seasoning, ground mustard, nutmeg and a big pinch of salt in a medium bowl and whisk to combine. Pour over the cooked pasta and stir to combine.

Step 4

Toss together the Cheddar, mozzarella and Gouda in a large bowl. Add the cheeses to the pot and stir to evenly combine. Transfer the mixture to a 9-by-13-inch baking dish.

Step 5

Bake until the center of the mac and cheese is set and the top is golden brown, 60 to 70 minutes. Let cool about 10 minutes before serving.
