Common Questions
Is this actually spicy?
It is more warm and toasty than hot. The smoked paprika and nutmeg are the main “festive” notes. Cayenne is optional and you can keep it to a pinch or skip it.
Can I make it without baking?
Absolutely. Once the pasta is tossed with sauce, you can serve it straight from the pot. If you still want crunch, toast the breadcrumbs in a skillet and sprinkle them on top.
What cheeses work if I do not have Gruyère?
Swap Gruyère for fontina, Gouda (smoked is great), or Monterey Jack. Keep at least one sharp cheese like cheddar for flavor.
Why did my sauce turn grainy?
Usually it is heat that is too high. Take the pot off the heat before adding cheese, then stir until melted. Also use freshly shredded cheese if possible, since pre-shredded often has anti-caking agents that mess with smooth melting. One more culprit: if the sauce reduces too much (or gets too acidic), it can push the cheese to break. If it starts looking tight, loosen it with a splash of warm milk or reserved pasta water.
Can I make it ahead for a party?
Yes. Assemble in the baking dish, cool, cover, and refrigerate up to 24 hours. Bake at 350°F covered for 20 minutes, then uncover and bake 10 to 20 minutes more, until hot in the center (165°F). Fridge-cold mac can take a little longer than you think. If it looks dry, splash a little milk around the edges before baking.
Can I freeze it?
Yes, best texture is freezing before baking. Wrap tightly and freeze up to 2 months. Thaw overnight in the fridge, then bake as directed (plan on extra time). Baking straight from frozen tends to give you a hot edge and a cold middle, so thawing is the move.
