The major advantage of purchasing a separate mini freezer is cost savings. Although it costs money to buy the freezer and keep it turned on, the extra space makes it possible to stock up on frozen vegetables, meats and other staples when they are at their lowest prices.
Having an extra freezer creates valuable storage space for ingredients and pre-made meals. When the local growing season ends, stores have to purchase fresh produce from suppliers around the globe. As a result out-of-season produce costs more and does not taste as good as in-season produce. With a separate freezer, it is possible to store large quantities of blueberries, strawberries and other seasonal produce picked at the height of freshness.
Extra freezer space also makes bulk cooking more convenient. With enough freezer space, cooks can prepare casseroles and stews several weeks or months in advance. Some cooks use the extra room to store cooked ingredients, reducing the amount of time it takes to prepare meals. Ree Drummond, host of "The Pioneer Woman," recommends using extra freezer space to store grilled chicken breasts, browned meat, and other ingredients for use in tacos, salads and soups.
With extra freezer space, shoppers can take advantage of bulk savings. In many cases, larger bags of frozen vegetables, pasta and other foods cost less per ounce than smaller bags. Shoppers with mini freezers can purchase several large bags at a time without worrying about running out of freezer space.
