A full freezer is a week you don't have to think about.
Buy in packs, portion the same day
Club packs are the cheapest way to buy chicken and beef, but the saving disappears if the whole tray goes in the freezer as one brick. Split it into single dinners the day it arrives and it thaws in an hour instead of a day.
Flat freezes faster
Anything flat freezes quicker, stacks better and thaws evenly. Ground meat pressed flat in a bag is the single best habit in a busy kitchen.
What freezes beautifully
Raw chicken and beef, burgers, schnitzel — breaded raw or already fried — soup, cholent, kugel, gefilte, kreplach, hotdogs and salami. Cooked roasts freeze well whole; slice them after thawing, never before.
What doesn't
Anything dressed with mayonnaise, cut salads, and cooked potatoes, which come back grainy.
Thaw in the fridge
Overnight, on a plate, on the bottom shelf. Not on the counter and not in warm water — the outside spoils long before the middle gives.
