How To Freeze Herbs – 3 Awesome Ways To Freeze Herbs

Today I’m going to explain how to freeze herbs. Freezing fresh herbs is an excellent way to preserve their flavor. First, I’m going to list the herbs that freeze best.

Second, I’ll walk you through the different techniques you can use to freeze herbs.

And third, I’ll leave you with some absolutely scrumptious recipes that you can try out, using your frozen bounty!

Let’s jump straight in!

Why Do We Freeze Herbs?

For those of us who grow a large variety of herbs, the same dilemma always occurs, when it comes time to harvest. We end up with far too much fresh produce! And unless you sell herbs, or make your own herbal teas and decoctions, or tinctures, you know there is going to be waste.

In order to use up all our lovely fresh herbs, it’s common practice to preserve as much as we can. In a previous article, I spoke about drying herbs, to store and preserve. You can read the entire article here.

Besides the storage factor, freezing herbs is an effective way to trap the essential oils inside the plant before they disappear. The more you handle the freshly harvested herbs, the easier it is for them to get bruised and damaged. This will seriously diminish their fragrance and appearance.

Freezing is an excellent way to preserve the aroma of your fresh herbs. When the time comes to use them the best way is to either cook from frozen or, in the case of teas, pour hot water over the frozen herbs and allow to steep. Then do a reheat but don’t boil. When cooking, they thaw fast and release their aroma into the food, adding depth and flavor to soups, casseroles, sauces, and teas.

Best Herbs To Freeze

When freezing herbs, choose fresh material with a high water content. Often these types of herbs don’t dry well unless the air is dry and the hanging area is well-ventilated. But often a lot of the flavor gets lost drying high water content herbs. That’s not to say you must not try! But if you have space to freeze sometimes it’s a better option. 

You can also freeze herbs with a lower water content, like thyme and rosemary. But they dry so well, it is often the preferred method.

Frozen herbs can be kept for up to 3-6 months in the freezer whereas dried herbs can be stored for longer (up to a year). I would not keep anything frozen for longer than 3 months.
