Oh, you want to go full time traveler? Yes, you can freeze homemade mac and cheese. But there are rules. You can’t just throw it in the freezer and hope for the best.
The best method: Assemble everything except the topping. Wrap the dish in plastic wrap, then a layer of foil. It will be fine for about 3 months.
To reheat, thaw it in the fridge overnight. Then add the topping and bake as usual. It won’t be quite as good as fresh, but it’s still 1,000 times better than the boxed stuff. I promise.
A Few Pro Tips (Because I’m Generous)
Use whole milk or half-and-half. Skim milk is a traitor in this dish. It will separate and make you cry.
Add a pinch of mustard powder or a dash of hot sauce. It doesn’t make it spicy; it just wakes up the cheese flavor. It’s like giving your sauce a good morning coffee.
And for the love of all that is holy, salt your pasta water. Like, aggressively. That’s the only chance you have to season the pasta itself. Don’t skip it.
