This simple method locks in that fresh, summer flavor so you can enjoy garden basil all year long.
If you’ve ever wondered how to freeze basil with olive oil the right way, you’re in the perfect spot.
Olive oil not only protects the basil from freezer burn but also gives you ready-to-use flavor bombs for sauces, soups, and sautés.
In this post, we’ll walk through the best ways to freeze basil with olive oil, why this method works so well, and some pro tips to keep your basil tasting fresh.
Let’s dive right in.
Why Freeze Basil With Olive Oil Works So Well
Freezing basil with olive oil is a game-changer for anyone who grows their own herbs.
Basil has a high moisture content, and freezing it plain often turns it into a mushy, black mess.
When you freeze basil with olive oil, the oil coats each leaf or piece, acting as a barrier against the cold air.
This barrier prevents oxidation, which is what causes that ugly browning and loss of flavor.
Plus, the olive oil itself becomes a delicious part of your dish later on.
So you’re not just preserving basil; you’re creating a convenient cooking shortcut.
Whether you freeze basil with olive oil in cubes or in a flat layer, you’ll end up with a product that’s far superior to dried basil.
1. It Preserves Fresh Flavor and Aroma
When you freeze basil with olive oil, you’re essentially flash-freezing the volatile oils that give basil its signature scent and taste.
Those volatile compounds are delicate and easily lost through drying or slow freezing.
Olive oil helps trap them, so when you thaw a cube, it smells like you just picked the leaves from the garden.
This is the biggest reason home cooks prefer to freeze basil with olive oil over other methods.
You get that bright, peppery, slightly sweet flavor that dried basil just can’t match.
2. It Prevents Freezer Burn and Discoloration
Freezer burn happens when moisture sublimates and leaves dry, grayish patches on your food.
Basil is especially prone to this because its leaves are thin and delicate.
But when you freeze basil with olive oil, the oil forms a protective coating that seals out the dry air.
Your basil will come out of the freezer looking green and vibrant, not sad and brown.
The olive oil also helps the basil keep its texture better, making it easier to chop or crumble right into your pan.
3. It Creates Ready-to-Use Portions
One of the best parts of learning how to freeze basil with olive oil is the convenience factor.
You can portion it into ice cube trays, and each cube is exactly the right amount for a single recipe.
Need a tablespoon of basil for a pasta sauce? Just pop out one cube.
Making a big batch of pesto? Grab two or three cubes and let them melt right in.
This makes meal prep a breeze during those busy weeknights.
You don’t have to thaw a whole bag of basil when you only need a little bit.
How to Freeze Basil With Olive Oil: Step-by-Step
Now, let’s get into the actual process of how to freeze basil with olive oil.
It’s super straightforward, and you only need a few basic tools.
Here’s what you’ll need: fresh basil leaves, good quality olive oil, a knife or food processor, ice cube trays, and a freezer-safe container or zip-top bag.
Follow these steps, and you’ll have perfectly frozen basil ready whenever you need it.
Step 1: Wash and Dry Your Basil Thoroughly
Start by picking fresh basil leaves and giving them a gentle rinse under cold water.
Dirt and tiny bugs like to hide in the creases of basil leaves, so don’t skip this step.
After rinsing, pat the leaves dry with a clean kitchen towel or use a salad spinner.
It’s crucial that the leaves are as dry as possible before you freeze basil with olive oil.
Any excess water on the leaves will turn into ice crystals, and those crystals can break down the cell walls of the basil.
Dry leaves also help the olive oil cling better to the surface.
Step 2: Chop or Blend the Basil
Next, decide whether you want chopped basil or a smooth puree.
For a rustic texture, simply stack the leaves, roll them up like a cigar, and slice them into thin ribbons.
For a smoother option, toss the whole leaves into a food processor and give them a few quick pulses.
Some people also like to blend the basil with a small amount of olive oil first to create a paste.
Either way, the goal is to break down the leaves a bit so they pack tightly into the trays.
This maximizes the amount of basil you can store in each cube.
Step 3: Pack the Basil Into Ice Cube Trays
Spoon or scoop the chopped basil into each compartment of your ice cube tray.
Don’t fill it all the way to the top; leave a little room for the olive oil.
A good rule of thumb is to fill each compartment about two-thirds full with basil.
Then, carefully pour olive oil over the basil until it’s fully submerged.
The oil should completely cover the basil to ensure no part of the leaf is exposed to air.
Gently tap the tray on the counter to release any air bubbles trapped in the oil.
Step 4: Freeze Until Solid
Place the ice cube tray on a flat surface in your freezer.
Make sure it’s level so the olive oil doesn’t pool to one side and leave some basil exposed.
Let the trays freeze for at least four to six hours, or preferably overnight.
Once they’re completely frozen solid, pop the cubes out of the tray.
If they’re stuck, run the bottom of the tray under warm water for a few seconds to loosen them.
Step 5: Store the Cubes for Long-Term Use
Now that you’ve got your basil and olive oil cubes, transfer them to a freezer-safe zip-top bag or airtight container.
Label the bag with the date so you know how long they’ve been in there.
Frozen basil cubes will last up to six months and still taste great.
When you’re ready to use them, just grab a cube or two and toss them directly into your hot pan.
There’s no need to thaw them first; the heat will melt the oil and release the basil flavor instantly.
Tips and Variations for Freezing Basil With Olive Oil
You’ve got the basics down, but there are a few extra tricks to make your frozen basil even better.
These tips will help you customize the method to suit your cooking style.
Let’s explore some creative ways to freeze basil with olive oil.
1. Use Garlic or Lemon Infused Olive Oil
Instead of plain olive oil, try using a garlic-infused or lemon-infused olive oil.
This adds an extra layer of flavor to your basil cubes without any extra work.
Imagine dropping a garlic-basil cube into a tomato sauce; it’s like having a ready-made flavor base.
Just be careful with garlic-infused oil, as the flavor can be strong.
Start with a mild infusion or mix it half and half with regular olive oil.
2. Freeze Flat for a Rustic Feel
If you don’t want cubes, you can freeze basil with olive oil in a flat layer instead.
Spread the chopped basil on a parchment-lined baking sheet and drizzle with olive oil.
Freeze until solid, then break the basil into large flakes or pieces.
Store these flakes in a bag, and use them like you would fresh chopped herbs.
This method works great for topping pizzas or folding into salads.
3. Don’t Forget the Pest Game
This method is essentially a shortcut to frozen pesto, minus the nuts and cheese.
If you want, you can add a pinch of salt, some minced garlic, and a squeeze of lemon juice to the basil before freezing.
When you melt the cube, you’ll have a quick sauce base that just needs pasta and a little parmesan.
It’s a brilliant hack for busy nights when you want homemade flavor in minutes.
4. Use Quality Olive Oil That You Love
Since the olive oil is a major component of the final product, don’t skimp on quality.
Use an oil that you enjoy eating, as its flavor will come through in your dishes.
A fruity extra virgin olive oil pairs beautifully with basil.
Mild olive oil is better if you want the basil to be the star of the show.
Taste your olive oil first, and if you wouldn’t dip bread in it, don’t freeze your basil in it.
So, Can You Freeze Basil With Olive Oil Easily?
Yes, you can absolutely freeze basil with olive oil easily, and it’s one of the smartest ways to preserve your harvest.
By following the simple steps above, you’ll lock in the fresh flavor and vibrant green color of your basil.
Whether you choose to freeze basil with olive oil in cubes or flakes, you’ll always have a tasty addition to your cooking.
Just remember to dry your leaves well, cover them completely with olive oil, and store them properly.
Next time your basil plant is overflowing, don’t let those leaves go to waste.
Grab your olive oil, break out the ice cube trays, and freeze basil with olive oil for those cold winter months.
Your future self will thank you every time you add a burst of summer flavor to a cozy winter stew.
