Store fresh oregano in a plastic bag in the refrigerator for up to 3 days. If you place a damp paper towel in the bag with the fresh oregano and leave some air in the bag, it may extend the life up to one week. You can also extend the life of fresh cut oregano by storing whole stems with leaves in a glass of water and a plastic bag loosely tented over the glass.
Fresh oregano may be frozen. Wash and dry oregano sprigs. Strip whole leaves from the stems and place in a plastic bag loosely without crushing, but remove all air. Keep in a location where it will not get crushed. Freeze. No need to thaw before using.
To dry oregano, tie sprigs into a bunch and hang in a cool dark place with good ventilation. Once dried, seal tightly and store away from sunlight.
Oregano goes well in just about any tomato dish. It also complements meats and vegetables with dominant flavors such as chili, spaghetti sauce, pizza, zucchini, broccoli, cauliflower, eggplant and lamb.
