How To Freeze Fresh Basil

Freezing fresh basil is a simple and effective way to preserve that vibrant, summer-fresh flavor for months.
 
If you’ve ever wondered how to freeze fresh basil without it turning into a black, mushy mess, you’re in the right place.
 
You see, freezing basil isn’t quite as straightforward as tossing the leaves in a bag, but once you learn the right methods, it’s incredibly easy.
 
In this post, we’ll walk you through the best ways to freeze fresh basil, why each method works, and how to use your frozen basil in cooking.
 
Let’s get started so you can enjoy that garden-fresh taste all year long.
 

Why You Can Freeze Fresh Basil Successfully

The good news is that you can freeze fresh basil, and it’s a fantastic way to reduce waste and save money.
 
The trick to successfully freezing fresh basil lies in understanding what causes it to turn dark and limp in the first place.
 
When basil leaves freeze, the water inside them expands, which can rupture the cell walls and lead to that unappealing brown or black color.
 
But, there are a few clever techniques that protect the leaves, so you can freeze fresh basil with excellent results every time.
 
These methods either remove the water, coat the leaves in oil, or puree them, all of which help maintain the color and flavor.
 
So, let’s dive into the top three approaches you can use to freeze fresh basil at home.
 

1. Freezing Whole Basil Leaves

The simplest way to freeze fresh basil is to do it with whole leaves, but it requires a quick blanching step first.
 
Blanching involves dropping the basil leaves into boiling water for just a couple of seconds, then immediately shocking them in an ice bath.
 
This process deactivates the enzymes that cause browning, so your basil stays bright green.
 
After patting the leaves completely dry, lay them in a single layer on a baking sheet lined with parchment paper.
 
Freeze them for a couple of hours until they’re solid, then transfer the frozen leaves to a zip-top freezer bag.
 
This method is perfect for when you need whole leaves for garnishes or for recipes that call for them to be added at the last minute.
 

2. Freezing Basil in Oil

Another excellent way to freeze fresh basil is to pack it in oil, which is my personal favorite for flavor.
 
You can do this by chopping the basil leaves and placing them into an ice cube tray.
 
Then, cover the chopped basil completely with a good quality olive oil, and pop the tray into the freezer.
 
Once the cubes are frozen solid, you can pop them out and store them in a labeled freezer bag.
 
The oil acts as a protective barrier, preventing the basil from getting freezer burn and locking in that fresh, peppery taste.
 
These basil-oil cubes are a godsend for quickly adding a burst of flavor to pasta sauces, soups, and sautés.
 

3. Freezing Basil as a Puree

You can also freeze fresh basil by pureeing it with a little water, which is a great option if you have a large harvest.
 
Simply blend the basil leaves with just enough water to create a smooth, thick puree.
 
Pour the puree into ice cube trays, or small silicone molds, and freeze until solid.
 
Once frozen, transfer the basil cubes to an airtight freezer bag or container.
 
Each cube is equivalent to roughly one tablespoon of fresh chopped basil, which makes it super easy to measure out for recipes.
 
This method is great for dishes where the basil will be cooked down, like in marinara sauce, curry, or pesto.
 

Tips for the Best Frozen Basil

To get the most out of your efforts to freeze fresh basil, there are a few key tips to keep in mind.
 
These simple steps will ensure that your frozen basil tastes as close to fresh-picked as possible.
 

1. Wash and Dry Thoroughly

Before you do anything else, always give your basil leaves a good rinse in cold water to remove dirt and any little critters.
 
After washing, drying is the most crucial step, as any excess water on the leaves will turn into ice crystals, which can degrade the texture.
 
Use a salad spinner to remove most of the water, then lay the leaves out on a clean kitchen towel and gently pat them dry.
 
You want the leaves to be as dry as possible before you freeze fresh basil, no matter which method you choose.
 

2. Label and Date Your Bags

It might seem obvious, but you’d be surprised how easy it is to forget what’s in that bag three months later.
 
Always use a permanent marker to write the date and the contents on the freezer bag or container.
 
Frozen basil is best used within six months, so dating ensures you use the oldest first.
 
Plus, labeling helps you avoid mistaking your basil cubes for your spinach cubes when you’re rummaging through the freezer.
 

3. Avoid Freezer Burn

Freezer burn is the enemy of all frozen foods, and basil is no exception.
 
To prevent it, make sure you squeeze out as much air as possible from your freezer bags before sealing them.
 
If you’re using containers, leave a little headspace for expansion, but make sure the lid fits snugly.
 
A vacuum sealer is the gold standard for this, but the water displacement method works great for zip-top bags.
 
Just seal the bag almost all the way, then dip it in a bowl of water, which forces the air out before you seal it completely.
 

What Not to Do When Freezing Basil

While you can freeze fresh basil, there are definitely some rookie mistakes you’ll want to avoid to get the best results.
 

1. Don’t Skip the Blanching for Whole Leaves

As we mentioned, you can freeze fresh basil leaves whole, but never do it without blanching them.
 
If you skip this step, the leaves will turn dark and discolored within a week, and the flavor will become bitter and unpleasant.
 
The two-second blanch and ice bath is your secret weapon for keeping those leaves vibrant and appealing.
 

2. Don’t Thaw at Room Temperature

When you’re ready to use your frozen basil, you should typically add it directly to your hot dish.
 
Thawing basil at room temperature will cause it to become slimy and watery, ruining its texture.
 
If you’re using whole leaves for a garnish, add them to the dish while they’re still frozen, or thaw them in the refrigerator for a very short time.
 
For pureed or oil-packed cubes, just toss them straight into the pan and let them melt into the heat.
 

So, How to Freeze Fresh Basil?

You can freeze fresh basil easily using one of three main methods: blanching whole leaves, packing them in oil, or making a simple puree.
 
Each method has its advantages depending on how you plan to use the basil later.
 
Whole leaves are best for finishing dishes, oil-packed cubes are amazing for sautéing, and pureed cubes are perfect for soups and sauces.
 
It’s a great way to preserve the taste of summer so you can enjoy it even when the snow is falling.
 
So don’t let that beautiful basil plant go to waste, get out there and freeze fresh basil today.
