How to Freeze Herbs

Learn how to freeze herbs and enjoy fresh-picked flavor all year long.

Throughout the summer, I pluck fresh herbs from my garden to add flavor to everything I cook—even in flavored herb butters. After learning how to store fresh herbs, I always keep some handy in the kitchen during the season for easy grabbing.

For years, though, as I watched the herb garden shrivel under the cold fall nights, I would dig up my rosemary bush, hoping to get it to overwinter inside. Alas, I could only make it to February before throwing a brown, shedding stick out the back door into the snow. But once I learned how to freeze herbs, I now look forward to having that fresh-picked taste anytime.

What’s the best way to freeze herbs?

Fortunately, there are multiple methods on how to freeze fresh herbs. Any of the easy ways below will work. But you’ll want to start each method with this crucial first step. Before freezing, rinse the herbs in clean water to remove any dirt. Then, pat them dry or dry them in a salad spinner.

How to freeze herbs in air-tight containers

Hardier herbs like rosemary, dill, thyme, bay leaves and sage can be frozen on their stem. Start by spreading the herbs in a single layer on a baking sheet, then place them in the freezer. Once the herbs are frozen, loosely place them in an airtight container or resealable plastic freezer bag. Then remove the sprigs one at a time as needed.

Don’t forget to label the bag or container with the type of herb and the date. Once frozen, many herbs look alike—you wouldn’t want to accidentally put basil in your rosemary sweet potato fries!

Editor’s Tip: If using a plastic bag, choose a designated freezer bag. The plastic is thicker and resists moisture better than a regular plastic bag. Press out as much excess air as possible or use a straw to suck the air out of the bag before sealing. You can do this by rolling the bag and securing it with butcher’s twine or a rubber band. A vacuum sealer works, too.

How to freeze herbs in water

For tender herbs like parsley and cilantro, remove the leaves from their stems. Pack them by tablespoonfuls into ice cube trays (a handy way to know how much you’re adding when cooking). Cover the herbs with water and place them in the freezer. Once the herbs are frozen, transfer them to an airtight container or resealable plastic freezer bag and label them.

Editor’s Tip: For an easy way to strip leaves from stems, bunch several stems together and run the tines of a fork from one end to the other several times.

How to freeze herbs in oil

For recipes like soups, sauces, pastas and others that can handle a touch of oil, freezing fresh herbs like basil, mint, oregano and tarragon in a bit of olive oil works beautifully.

First, remove the leaves from the stems. Chopping the leaves results in a rough, paste-like texture. If desired, pulse 2 cups of herb leaves with 1/3 cup olive oil in a food processor. (If you don’t have a food processor, here’s a helpful guide on how to chop herbs.)

Add the chopped herbs to a freezer bag and lay flat to freeze. (This saves a ton of freezer space!) Once frozen, you can break off sections to use as needed.

How long can you keep fresh herbs in the freezer?

Using the methods above, frozen fresh herbs can last in the freezer for up to 12 months. Frozen herbs taste much closer to fresh herbs than dried herbs and retain more of their nutrients.

Pro Tip: While frozen herbs taste delicious, their texture and appearance will be mushy and soft, so they aren’t pretty. Plan to use them to flavor soups, stews, gravies and cooked dishes rather than using them in salads or as a garnish.

How to Thaw Frozen Fresh Herbs

The best part about learning how to freeze fresh herbs is that there’s no thawing step. Letting the herbs thaw will either result in limp and soggy herbs (if you froze them still on their stem) or watered-down herbs (if you froze them in water or with oil). Instead, add the frozen herbs directly to your dish for the best results.
