How to Freeze Basil + Recipes to Use Frozen Basil

Freezing basil minimizes food waste and ensures you always have some on hand for soups, stews, sauces, and more! This post explains how to freeze basil 4 ways, plus you’ll get access to 10+ basil recipes. 

I’m going to be using my own tips in this tutorial on How to Freeze Basil – my basil plant was huge after our week long Mexico vacation! It is amazing how quickly it grew after an unattended (and unused) week!

Why Should You Freeze Basil? 

Fresh basil is abundant in the summer months, but unfortunately this delicate herb doesn’t stay fresh for long once harvested. The solution? Freeze it! 

If you have a big basil harvest from your garden this year, freezing it is your best option. Basil leaves can be frozen a few different ways and their flavor isn’t impacted whatsoever once thawed. 

These methods for freezing basil leaves can be used year-round, not just in the summer months. 

Even I have trouble using up an entire packet of fresh basil from the grocery store, so I sometimes freeze just one or two portions of it at a time. It’s better than throwing away perfectly good basil! 

How to Freeze Basil 

Can you freeze fresh basil? Absolutely! You have a few options when it comes to freezing basil. 

Below are four of my favorite methods for freezing basil leaves. If you’re unsure how to freeze fresh basil, try one of the options below. 

You’ll find a free printable with instructions 4 ways to freeze fresh basil for your records at the bottom of this post.

1. Freezing Basil in Olive Oil

To a food processor, add roughly 2 cups of packed fresh basil leaves. Drizzle in 2 tablespoons of olive oil. Puree until the basil leaves are chopped up to your liking (you can leave them slightly chunky, or puree them completely). 

Once pureed, dollop the oil-basil mixture onto parchment-lined baking sheet(s). I like to use a large spoon or a tablespoon measure to do this. 

Place the baking sheet into the freezer, making sure not to tilt it. Freeze until the olive oil-basil mixture is solid, about 1 hour. 

Then, quickly transfer the frozen basil to a zip-top freezer bag. When ready to use, add straight to the recipe. 

2. Freezing Basil in Ice Cube Trays

Chop the basil, then press into an ice cube tray. Fill each well with water. Freeze the ice cubes until solid, then pop out of the tray and seal inside a zip-top bag. (You can also chiffonade your basil: How to Quickly Chiffonade Herbs)

When ready to use, place the frozen basil cubes in a bowl and let the ice melt. Drain the water from the bowl and proceed with the recipe as written. 

Tip: I recommend using silicone ice cube trays for this method, as they’re more flexible and make it easier to remove the frozen basil. 

3. Freezing Basil Leaves Whole 

To freeze basil leaves whole, you’ll first need to blanch them for 2 seconds in boiling water (I like to lower them into the pot and remove them using a metal sieve). 

Then, plunge the blanched basil leaves into a bowl of ice water. Remove the basil from the bowl, gently pat dry using a clean kitchen towel, and store in a freezer-safe container. 

It’s best to freeze basil leaves in layers separated by parchment paper. This way, the frozen basil doesn’t form one giant clump. 

4. Freezing Basil in Pesto 

Did you know that basil can be turned into pesto and then frozen? Pesto is essentially a step up from freezing basil in olive oil, if you think about it. 

Here are my go-to pesto recipes for using up fresh basil: 

• Walnut Almond Pesto – this is a traditional basil pesto that uses walnuts and almonds instead of pine nuts.
• Kale Pesto – this kale pesto recipe uses cilantro, but you can definitely substitute basil and make a basil kale pesto.
• Vegan Basil Pesto – in this vegan basil pesto, you use nutritional yeast instead of Parmesan to get that “cheesy” flavor.

I prefer freezing pesto in silicone ice cube trays or in small jars. This way, I can thaw out the exact amount of pesto I need for a recipe and no more. Pesto can be stirred into a dish from frozen, no need to thaw first! 

How Long Is Frozen Basil Good For? 

Frozen basil will last up to 1 year in the fridge, noting that the leaves may turn black over time. 

In general, basil frozen in olive oil (either in plain oil or as a pesto) will remain greener for longer. Basil that’s frozen in water or by itself will turn black much quicker. 

How to Thaw Frozen Basil 

Because basil is such a delicate herb, it can be thawed in a matter of minutes. Simply remove the frozen basil from the freezer and place on your countertop. 

Basil frozen in oil will take 10 to 15 minutes to thaw completely (depending on how large your dollops are), and frozen whole basil leaves will thaw in a couple of minutes. 

Do You Have to Thaw Frozen Basil? 

Nope, not always! You can add frozen basil (in any form) straight to soups, sauces, and stews. No need to thaw first!
