Macaroni and Cheese

Why This Macaroni and Cheese Works

During cooking, the butter and flour cook together first and turn into a paste. As the milk goes in and heats up, the flour soaks it in and the whole thing slowly thickens. It starts out thin, then after a few minutes it becomes a smooth, creamy sauce that can actually cling to the pasta instead of sliding off.

Once the cheddar, Gruyère, and Parmesan melt into that hot sauce, the cheese spreads all through it instead of clumping. The mustard, garlic, and onion powders mix in at this point too, so they’re carried in every bite. When the cooked macaroni goes into the pot, the hollow noodles fill up with the sauce and the starch on the pasta grabs onto it, so the cheese stays on the pasta.

In the oven, the sauce bubbles and settles into all the gaps between the macaroni. The breadcrumbs mixed with olive oil brown on top and turn crisp, while the pasta underneath stays soft and creamy.

Mistakes To Avoid

Boiling the macaroni until it’s very soft instead of al dente makes it fall apart later. Once it bakes in the sauce, the pasta keeps cooking, so overcooked noodles turn mushy and lose any bite, and the whole dish can feel like a thick paste instead of separate, creamy pieces.

Letting the roux and milk mixture stay thin and runny before adding the cheese leaves the sauce watery. The cheese then melts into a loose liquid instead of a smooth, clingy sauce, so the macaroni sits in a pool and never gets that rich, coating texture.

Adding the cheese over high heat or to a boiling sauce often makes it turn grainy. The proteins tighten and separate from the fat, so instead of a silky cheese sauce, the pan fills with little curds and an oily layer that will not smooth out in the oven.

Skipping the oil on the breadcrumbs or using them completely dry leads to a dusty topping. In the oven, the crumbs brown unevenly, stay hard in spots, and can burn on top while the layer underneath stays pale and powdery.
