Why Freeze Fresh Basil?

Preserving basil is a fantastic way to maintain the abundance of this herb that often comes from growing basil plants.

As gardeners know, basil plants can produce more leaves than you can use at once, especially during summer.

By choosing to freeze basil, you can extend the life of these fresh herbs and ensure you have a supply ready for your culinary adventures throughout the year. Its vibrant taste brings an ideal enhancement to so many dishes. The freezing process transforms fresh leaves into frozen herbs that retain much of their original flavor and aroma.

This preservation method allows you to enjoy the essence of fresh basil in your dishes long after the growing season has passed.

Does Frozen Basil Taste Good?

Frozen basil might have a different fresh flavor and texture than fresh basil leaves, but it certainly retains all its charm.

Frozen fresh basil retains most of its unique aroma and taste, which can still enhance your dishes beautifully.

The freezing process can alter the texture, making it a bit limp, so it might not be the best for garnishing. However, it is perfectly fine in sauces, soups, or stews where the texture is not as crucial and gives the dish a quick pop of herb flavor.

Is It Better to Freeze Basil or Dry It?

When it comes to preserving herbs like basil, the method you choose can greatly affect the flavor and usability of the herb in your future culinary endeavors.

Freezing fresh basil is often considered a better option compared to drying, particularly if you want to preserve the vibrant, fresh taste that basil brings to dishes.

The freezing process can maintain the herb’s robust flavor, making it ideal for use in sauces, stews, or other cooked dishes.

On the other hand, drying basil changes its flavor profile, making it more concentrated and less fresh-tasting.

Dried basil is commonly used to flavor pizzas, salads, pasta, and meats, as well as being a key ingredient in pesto and a seasoning for dishes like soups, rice, lentils, and chickpeas.

Nonetheless, drying isn’t the most effective preservation technique for delicate leafy herbs like basil, cilantro, tarragon, lemon balm, and mint.

How to Freeze Basil: A Step-By-Step Guide

Freezing fresh basil is an excellent way to preserve its vibrant color and distinct flavor. Here’s a comprehensive guide on how to freeze basil.

Supplies Needed:

How to Freeze Basil

Clean and Dry the Basil Leaves

Start by washing basil with cold water. Then place them inside a salad spinner to dry basil.

After using the salad spinner, the leaves might still have some residual moisture. To remove this, gently pat the basil dry with a paper towel.

Make sure to do this delicately to avoid crushing or damaging the leaves. The key here is to ensure the leaves are completely dry but still intact.

Remove the Stems

Using a sharp knife, cut the stems from the basil leaves, and remove the leaves from the stems.

Chop the Basil

Place the leaves on your cutting board and chop them into small pieces. The size can be imperfect, as they will be further broken down in the freezing process.

Method 1: Freezing Basil in Ice Cube Trays

Fill the Trays

Distribute the chopped basil evenly among the compartments of your ice cube trays.

Add Liquid

Either submerge the basil in water or drench it with olive oil.

Both methods work well, but oil can help retain the basil’s vibrant green color and add extra flavor.


Place the trays in the freezer and wait until the cubes are solid, which should take 2-4 hours.


Once frozen solid, pop the basil ice cubes out of the trays and transfer them to a freezer bag or freezer-safe container. Be sure to squeeze out as much air as possible before sealing the bags. These basil cubes can be stored in the freezer for up to six months.

Method 2: Making Basil Pesto

Blend the Basil

Start by cleaning and coarsely chopped basil leaves. Place them in your food processor bowl. As you begin blending, gradually drizzle olive oil into the mix. This process helps to break down the basil and combines everything into a smooth paste. The slow addition of oil while blending ensures a well-emulsified and flavorful basil pesto.


Spoon the basil paste into ice cube trays and freeze until solid.

Like the first method, once the basil paste cubes are frozen, transfer them to freezer bags for long-term storage.

Can I Freeze Basil Without Blanching?

Yes, you can freeze basil without blanching. One method is to pack the basil leaves straight into a baggie or container and then freeze them.

However, it’s important to note that fresh basil has enzymes that can cause it to darken in the freezer.

If your goal is to preserve the fresh green color of the basil, blanching for 2-4 seconds in boiling water before freezing can help as it kills these enzymes.

How Do You Defrost Frozen Basil?

Defrosting frozen basil is a simple process. First, remove the basil from the freezer and let it sit at room temperature.

This allows the ice crystals to melt naturally without damaging the delicate leaves. If you’re in a hurry, submerge the frozen basil in a sealed plastic bag in a bowl of cold water.

This helps speed up the thawing process but do not let the water get into the bag, as it could make the basil soggy.

After the basil has thawed, lightly dab it using a paper towel to eliminate any surplus moisture before incorporating it into your dish.

How Long Does Frozen Basil Last?

According to various sources, frozen basil can last up to a year in the freezer. However, it’s important to note that the quality may decline after about three months.
