It’s possible to freeze some fresh herbs and maintain good flavor, when you have an overabundance of such green glory. Plan on using frozen herbs for cooking; you won’t be able to use them in applications that call for raw fresh herbs. Thyme, rosemary, and sage can be rinsed, dried well, and stored in zipper-top freezer bags as is. It’s a snap to strip the leaves from the still-frozen stems, says MakingSense. Parsley leaves can be washed, dried, chopped, and frozen loose in freezer bags. Just grab the amount you need to throw into your dish.
There’s no satisfactory way to freeze whole basil leaves, but they can be minced finely, mixed with a little bit of olive oil and frozen in ice cube trays. Pop the cubes into a freezer bag and add them directly to sauces, etc., as they cook.
SeaSide Tomato makes herbed salts with end-of-season herbs, which can be enjoyed year ‘round and make great gifts. Wash, dry, and tear the leaves of fresh herbs in small pieces, and combine with kosher or sea salt in a ratio of 2/3 salt to 1/3 herbs or half and half. Use a combination of herbs or a single type, depending on your preference. The salt can be stored in tightly sealed bags for months (it will be damp at first, from the fresh herbs, but will dry out over time). Transfer the salt to pretty jars for gift giving or to keep in your spice rack.
