Store food in portions you'll actually eat.
A big, frozen platter of lasagna sounds great—until it's 5 pm, you and one other person in your family want to eat it for dinner tonight and it's rock solid. Becky Rosenthal, author of Fast to the Table Freezer Cookbook, often feeds her family of three with trays of food she's made ahead and frozen. Her trick: Instead of putting the entire recipe's worth into one 9- x 13-inch baking dish, she packages the meals in sizes that make sense for her family. An 8- x 8-inch container of lasagna is perfect for them; plus, the smaller portion defrosts more quickly. (Rosenthal uses foil trays, so she doesn't have to leave one of her own dishes in the freezer for weeks.)
