Cook for 20 minutes at 375F/190C, or until bubbling and golden.Place the pasta in a skillet or a lightly greased 2-quart baking dish sprinkle with the remaining cheese.After that, throw in the cooked pasta and mix everything up thoroughly.Add the cheeses, setting aside some for garnishing, and whisk until melted, blended, and smooth.Put on low heat and simmer for 2 minutes.Toss in some salt, pepper, Creole seasoning, and cayenne pepper, along with the onion and garlic powder.
Keep at a low boil for about 5 minutes, or until the liquid has thickened somewhat.
Do not add the evaporated milk or the half and half all at once, but rather gradually this will prevent lumps from forming. Continue cooking for a minute to remove any trace of flour flavor. Whisk until all of the flour and butter are evenly combined. When the butter has melted in the pan, mix in the flour. Pasta should be prepared in accordance with package instructions. Serve immediately (very creamy) or pour into a buttered baking dish, top with extra cheese, and bake at 350˚ for 20 to 25 minutes, or until bubbly and golden on top. (Do not under-salt!) Pour in the drained, cooked macaroni and stir to combine. Taste the sauce and add more salt and seasoned salt as needed. Step 5 Pour the egg mixture into the sauce, whisking constantly. Step 4 Take 1/4 cup of the sauce and slowly pour it into the beaten egg, whisking constantly to avoid cooking the egg. Pour in the milk, add the mustard, and whisk until smooth. Cook the mixture for 5 minutes, whisking constantly.
Step 3 Melt the butter in a large pot and sprinkle in the flour. The macaroni should be too firm to eat right out of the pot.
Step 1 Cook the macaroni until very firm.
