How to Use Frozen Herbs Instead of Fresh Ones

Use frozen herbs in place of fresh herbs by adding them directly from the freezer to the dish without thawing them first. Soft-leaved herbs such as parsley, dill, and mint lose their cellular structure when frozen. As they thaw, they release liquid and cannot retain their leaf shape, so they are better suited to cooked dishes than to salads or raw garnishes. The difference is not only visual but also textural: fresh leaves stay crisp, while frozen leaves soften and darken as they thaw. For dishes where presentation matters, fresh herbs remain the better choice.

Which herbs can be frozen?

Leafy herbs such as parsley, dill, mint, basil, and garden cress can be chopped and frozen in small bags or ice cube trays. Broad-leaf greens such as spinach and Swiss chard can also be frozen after briefly blanching and draining them; if frozen without blanching, they become mushy when thawed. For firm herbs such as thyme and bay leaves, drying is more practical than freezing because they retain much of their aroma when dried and last much longer on the shelf than frozen herbs. Store-bought frozen herb packages are used the same way. Refreezing after opening is not recommended because each freeze-thaw cycle causes the leaves to lose more moisture, darken, and lose aroma. Buying frozen herbs in small portions instead of a large package helps keep an opened package from sitting in the freezer for a long time.

When should frozen herbs be added to a dish?

Add frozen herbs during the last few minutes of cooking. If added too early, they can lose their color and aroma during a long cooking time, and some herbs may develop a slight bitterness. For hot dishes such as soup, sautéed dishes, or omelets, stirring them in just before removing the dish from the heat is enough. The heat of the dish will warm the herbs in a few seconds, so no additional wait is needed. If you want to add frozen herbs to salad dressing or cold appetizers, let them sit at room temperature for a few minutes first, then blot away excess liquid with a paper towel. Otherwise, the dish may become unnecessarily watery and its flavor diluted.

Should you use the same amount as fresh herbs?

Frozen herbs can generally be used in the same amount as fresh herbs. Because their volume shrinks a little when frozen, you may want to use a little more if a recipe calls for a handful of fresh herbs. Dried herbs are different: use much less than fresh or frozen herbs because drying concentrates their aroma, and even a small amount creates a noticeable flavor. Overall, frozen herbs are a practical, economical option for cooked dishes during winter, when fresh herbs are unavailable or expensive. The main points are to avoid using them in raw presentations and to add them near the end of cooking.

How do color and aroma differ?

Frozen herbs are a little darker and duller than the vivid green of fresh herbs because some chlorophyll in the cell walls breaks down during freezing. The difference in aroma is smaller: thawed frozen herbs smell almost the same as fresh herbs, though their aroma becomes slightly weaker within a few hours. For dishes where appearance matters, choose fresh herbs; for cooked dishes where aroma matters most, frozen herbs are a convenient choice.
