When you know how to make basil pesto for freezing properly, you’ll never have to buy the jarred stuff again.
In this post, we’ll cover the best methods for making basil pesto for freezing, the ideal ingredients, and how to store it so it stays bright green and delicious.
Let’s dive right in.
Why Freeze Basil Pesto Instead of Just Storing It Fresh
Freezing basil pesto is the ultimate way to lock in that garden-fresh taste long after the basil plant has finished for the season.
When you make basil pesto for freezing, you’re essentially capturing the peak of summer in a convenient, ready-to-use form.
Fresh pesto only lasts about a week in the fridge, but frozen pesto can last for up to six months without losing its punch.
The key is that freezing stops the oxidation process, which is what causes pesto to turn brown and lose its vibrant color.
So, if you’re wondering how to make basil pesto for freezing that keeps its bright green color, the secret lies in a few simple steps.
1. The Blanching Method for Maximum Green
Blanching your basil leaves before blending is a game changer when you make basil pesto for freezing.
This quick dip in boiling water, followed by an ice bath, deactivates the enzymes that cause browning.
To blanch, bring a pot of water to a rolling boil and drop in your basil leaves for just 10 to 15 seconds.
Immediately transfer them to a bowl of ice water to stop the cooking process.
Pat them dry thoroughly before using them in your pesto.
This extra step ensures that your frozen pesto stays a beautiful, appetizing green.
2. The No-Blanch Shortcut
You can also make basil pesto for freezing without blanching, and it will still taste amazing.
Simply wash and dry your basil leaves completely, as any excess water can lead to ice crystals and a watery pesto.
Then, proceed with your favorite pesto recipe using garlic, pine nuts, parmesan, and olive oil.
The color might be slightly darker than blanched pesto, but the flavor will still be fantastic.
If you’re in a hurry, this is the easiest way to freeze basil pesto without any extra fuss.
How to Make Basil Pesto for Freezing: The Perfect Recipe
Here is a foolproof recipe to make basil pesto for freezing that’s balanced and freezes beautifully.
You’ll need about two cups of packed fresh basil leaves, which is roughly one large bunch.
Add in half a cup of grated parmesan cheese, a third of a cup of toasted pine nuts, and two garlic cloves.
Place all of these ingredients in a food processor and pulse until they are coarsely chopped.
With the processor running, slowly drizzle in about half a cup of extra virgin olive oil.
For freezing, you want the pesto to be slightly looser than you would serve fresh, so add a bit more oil if needed.
Season with salt and pepper to taste, but go light on the salt because parmesan adds saltiness.
When you make basil pesto for freezing, you can also omit the parmesan and add it later after thawing.
This is because parmesan can sometimes alter the texture after being frozen and thawed.
The choice is yours, and both methods work wonderfully.
1. Toast Your Nuts First
Toasting your pine nuts or walnuts before adding them is a crucial step in the best way to make basil pesto for freezing.
Toasting brings out their natural oils and adds a deeper, nuttier flavor that really shines through.
Just place them in a dry skillet over medium heat for a few minutes, shaking frequently until fragrant.
Keep a close eye on them as they can burn quickly and become bitter.
Once toasted and cooled, they’re ready to be blended into your pesto.
2. Use High-Quality Olive Oil
The olive oil is the backbone of any pesto, and it’s especially important when you want to freeze basil pesto.
Use a good quality extra virgin olive oil that has a robust, peppery flavor.
The oil not only carries the flavors but also acts as a protective barrier against air, helping to prevent oxidation.
When you pour a thin layer of olive oil over the top of your pesto before freezing, it seals it from freezer burn.
This simple trick is how to make basil pesto for freezing that tastes just as fresh as the day you made it.
Best Ways to Store Your Freezer Pesto
Now that you know how to make basil pesto for freezing, let’s talk about the best containers and methods.
The right storage method makes all the difference in both convenience and longevity.
There are three main ways you can store frozen basil pesto, and each has its own benefits.
Choose the one that best fits how you plan to use the pesto later.
1. Ice Cube Trays for Perfect Portions
Using ice cube trays is arguably the most popular way to freeze basil pesto for individual portions.
Spoon your pesto into the trays, filling each cavity almost to the top.
Place the trays in the freezer until the pesto is solid, which usually takes a few hours.
Once frozen, pop the pesto cubes out and transfer them to a zip-top freezer bag.
This method gives you perfectly measured portions to drop into pasta sauces, soups, or marinades.
Each cube is typically about one to two tablespoons, which is perfect for a single serving of pasta.
2. Freezer Bags for Bulk Storage
If you often cook for a crowd or like to make large batches of sauce, freezer bags are a great option.
Fill a resealable freezer bag with your pesto and flatten it out to remove as much air as possible.
Laying the bag flat in the freezer allows it to freeze quickly and stack neatly.
When you need pesto, simply break off a piece of the frozen slab and use it.
This method is efficient for storing big batches, and you can easily freeze basil pesto in any quantity.
3. Small Glass Jars
Glass jars are also excellent for freezing basil pesto for short-term storage of a few weeks.
Make sure to leave about half an inch of headspace at the top, as the pesto will expand when frozen.
You can also pour a thin layer of olive oil over the pesto in the jar to create a seal.
This oil layer will protect the pesto from the air and keep that bright color intact.
Just remember to thaw glass jars in the refrigerator to prevent thermal shock and cracking.
How to Thaw and Use Frozen Basil Pesto
Knowing how to make basil pesto for freezing is only half the battle; you also need to know how to thaw it.
The best way to thaw frozen basil pesto is to move it from the freezer to the refrigerator overnight.
For a quicker method, you can place the sealed bag or container in a bowl of cold water.
Avoid using the microwave to thaw pesto as it can cause the olive oil to separate and the flavors to dull.
Once thawed, give it a good stir to recombine any ingredients that may have separated.
If the pesto is a bit watery, you can drain off the excess liquid or add a fresh sprinkle of parmesan.
You can also add a little fresh lemon juice to brighten up the flavor after freezing.
Pro tip: You can add frozen pesto cubes directly to hot pasta or soups without thawing.
The heat will melt the pesto and release all the flavors perfectly.
This is one of the most convenient ways to use your frozen stash.
So, How to Make Basil Pesto for Freezing Successfully?
Making basil pesto for freezing successfully is all about proper preparation and storage.
Whether you choose to blanch your basil or use it raw, the recipe remains simple and delicious.
The best way to freeze basil pesto is to decide on your portion sizes beforehand, using ice cube trays or bags.
Remember to coat the top of your pesto with a little olive oil to ensure a longer shelf life.
By following these steps, you can make basil pesto for freezing that preserves that burst of summer flavor.
So next time you have an abundant basil harvest, don’t let it go to waste.
