Before you freeze herbs

Frozen herbs retain their flavor, vitamins and color exceptionally well. The  key is to make sure that they are absolutely fresh. Pick them in the morning, then prepare and freeze them right away.

Before freezing herbs,  you will need to prepare. Washing and drying the herbs ahead of freezing will save a lot of time.

Wash the herbs well and allow them to dry on a kitchen towel. Remove any thick stems before chopping unless you are going to freeze whole stems.

Now, let’s discover how to freeze them!

How to freeze herbs 7 ways

From freezing herbs in ice cube trays to making herb-infused oils and a simple pesto, here is how to make the most of your herbs for winter cooking. 

Try one of these 7 ways to freeze fresh herbs for later use:

Freeze herbs in water in ice cube trays

Some herbs are better suited to freezing in water in ice cube trays than others because of their moisture content and the way they hold up to freezing.

Basil, mint, chives and parsley are some herbs which freeze well in water since they have a high water content and delicate leaves.

Fragile herbs like these tend to lose their flavor when air dried, so freezing is perfect for them.

After washing and drying the herbs, chop them finely. Place a teaspoon or so of chopped herbs into each compartment of an ice cube tray.

Fill the compartments with water  to cover the herbs and freeze the ice cube tray.

Once frozen, transfer the herb cubes to a labeled freezer bag for easy, single-serve portions. To use the frozen herbs, simply drop a cube into your pan and cook as usual.

How to freeze fresh herbs in oil in ice cube trays

Rosemary, thyme and oregano are just a few of the herbs that freeze well in oil. Herbs  frozen in some oil can be easily used in a soup or in a sauce

Prepare the herbs and chop them. Fill an ice cube tray compartment about halfway with your chosen herb.

Cover the herbs with olive oil or a neutral oil like canola or grapeseed oil, making sure they are fully covered with the oil.

Freeze overnight until solid. Remove the herb oil cubes from the tray and transfer them to a labeled freezer bag for storage.

When using these herb oil cubes in your cooking, simply drop a cube or two into your pan or recipe directly from the freezer bag. The oil will melt, releasing the herb’s flavors and aroma into your dish.

Blanching and freezing fresh herbs

Blanching herbs before freezing helps to retain their vibrant color and fresh flavor. It stops enzymes responsible for color and flavor deterioration, preserving the herbs’ quality.

Blanching also softens the cell walls of the herbs, which can help maintain their texture when frozen and thawed.

Wash and dry the herbs first.

Make herb butter and then freeze

Herb butter will enhance the flavor of all your fall dishes. Freezing herbs in butter easy and the process can be customized with your favorite herbs and seasonings.

It is made similarly to the herb oil freezing trick above. Here is how to make it:

Blend washed and dried herbs with melted unsalted butter until the herbs are mixed well.

Spoon the mixture into ice cube trays and freeze until solid. Once frozen, you can transfer the herb butter cubes to freezer bags.

You can use herb butter for cooking or as a finishing touch for dishes.

Freeze herb pesto

Basil is a herb that freezes best when it is first made into pesto. You can also use other herbs such as oregano or thyme.

Remove the stems and combine about a cup of your chosen herb with 1/4 cup of olive oil in a food processor or with a mortar and pestle.

Blend well, then transfer the mixture into ice cube trays. Once frozen, transfer the pesto cubes to a freezer bag.

Use pesto cubes for pasta, sandwiches, or as a sauce for various dishes. Any dish which likes the addition of oil will work well with pesto cubes.

Flash freezing chopped herbs on baking sheets

Flash freezing works well for many types of herbs, particularly those with delicate leaves such as basil, cilantro, dill and parsley.

It is very simple to do. All you need are some fresh herbs, a baking tray and freezer bags.

Wash the herbs and thoroughly dry them to remove any excess moisture.

Finely chop the herbs with a knife, herb scissors or food processor. Line a baking sheet that will fit in your freezer with parchment paper or a silicone baking mat. 

Spread the chopped herbs in a single layer on the baking sheet.  Try to make sure that they do not touch each other. This will keep them from sticking together when frozen.

Place the baking sheet in the freezer and let the herbs freeze for a few hours. Once the herbs are frozen, remove the baking sheet from the freezer, and quickly place the frozen chopped herbs into an airtight freezer bags.

Try to remove as much air as possible to prevent freezer burn. Label the container or bags with the herb type and date.

When it’s time to use the frozen herbs, take out the desired amount and return the rest to the freezer. Flash freezing herbs makes it convenient to portion them for various recipes.

When properly frozen and stored, flash frozen herbs can last for several months to a year.

The exact time will vary depending on factors such as the type of herb, how well it was dried before freezing, and how airtight your storage containers or bags are.

Freeze whole herb sprigs in plastic bags

Freezing whole herb sprigs is a great way to preserve fresh herbs for later use, especially if you want to use the leaves and stems together.

It works best for hardy herbs like rosemary, dill, thyme, bay leaves or sage

Harvest herbs in whole sprigs or use store-bought bunches. Rinse them under cold running water to remove any dirt or debris.

Gently pat them dry with a paper towel. Trim any discolored or damaged leaves or stems from the sprigs.

You will be freezing the entire sprigs for this method. Lay the cleaned and trimmed herb sprigs in a single layer on a baking sheet. Make sure they are not touching each other.

Place the baking sheet in the freezer and allow the herb sprigs to freeze until they are solid. This typically takes a few hours.

Once frozen, remove the herb sprigs from the baking sheet and store them in labeled freezer bags or an airtight container.

Be sure to remove any excess air if using bags. Label and date the herbs.

When you want to use the frozen herb sprigs, you can add them directly to your recipes without thawing. They work well in soups, stews, roasts, and other dishes that benefit from the slow release of flavors during cooking.
