If you’ve been wondering how to freeze basil in olive oil without blanching, the answer is simple: chop, cover, and freeze.
No blanching needed, no ice bath, no fuss.
In this post, we’ll walk through the best way to freeze basil in olive oil without blanching, why it works so well, and a few pro tips to make sure your frozen basil tastes just-picked.
Let’s dive right in.
Why You Can Freeze Basil In Olive Oil Without Blanching
Freezing basil in olive oil without blanching works because the oil acts as a protective barrier against air and ice crystals.
Blanching is traditionally used to deactivate enzymes that cause browning and off-flavors, but olive oil does a surprisingly good job of minimizing that damage.
When you freeze basil in olive oil without blanching, the oil coats each leaf piece and locks in the essential oils that give basil its signature taste.
Plus, skipping the blanching step saves you time in the kitchen, which is always a win.
The key is to prepare the basil properly and use high-quality olive oil, so your frozen cubes are ready for sauces, soups, and sautés anytime.
1. The Oil Protects the Basil’s Flavor
When you freeze basil in olive oil without blanching, the oil prevents direct contact with cold air inside the freezer.
This reduces freezer burn, which is that dry, mushy texture you get when food is exposed to air.
The olive oil also carries fat-soluble flavor compounds, so your basil actually tastes richer after freezing.
It’s a clever trick that keeps basil tasting fresh without the extra pot of boiling water.
2. No Mushy Leaves After Thawing
Blanching can sometimes make basil leaves waterlogged, especially if you don’t dry them perfectly.
But when you freeze basil in olive oil without blanching, the leaves stay more intact because the oil replaces water in the freezing process.
This means your thawed basil won’t turn into a sad, soggy pile.
Instead, you’ll have pliable pieces that mix beautifully into pesto, pasta, or marinades.
3. It’s a Time-Saving Kitchen Hack
Blanching requires boiling water, an ice bath, and careful drying, which can take a good 15 minutes.
Freezing basil in olive oil without blanching cuts that down to just a few minutes of prep.
You’ll spend more time chopping and less time babysitting pots on the stove.
For busy cooks, that’s a huge advantage when you have a big bunch of basil to preserve.
How To Freeze Basil In Olive Oil Without Blanching, Step By Step
Ready to get freezing?
Here’s the foolproof method to freeze basil in olive oil without blanching, plus a few variations to suit your cooking style.
Step 1: Wash and Thoroughly Dry the Basil
Start by gently washing your basil leaves under cold water to remove dirt or tiny bugs.
Then, it’s crucial to dry them completely, because any lingering water will create ice crystals and dilute the flavor.
Use a salad spinner or pat each leaf with a clean kitchen towel.
The drier the leaves, the better your frozen basil will taste.
Step 2: Chop or Tear the Leaves
You can leave small leaves whole, but tearing or chopping larger leaves helps them fit snugly into ice cube trays.
A rough chop is all you need, since the basil will be cooked or blended later anyway.
If you prefer a finer texture, you can pulse the basil in a food processor with a little olive oil first.
Step 3: Fill Ice Cube Trays with Basil
Pack the chopped basil into each compartment of an ice cube tray, filling them about 70–80% full.
Don’t pack too tightly, you want room for the olive oil to seep in and coat everything.
This is the core technique when you freeze basil in olive oil without blanching, so make sure every piece is lightly nestled.
Step 4: Pour Olive Oil Over the Basil
Slowly pour a good-quality extra virgin olive oil over the basil until each cube is completely submerged.
The oil should cover the leaves entirely, with no bits poking out at the top.
Exposed basil will oxidize and turn dark, so full coverage is non-negotiable.
Step 5: Freeze Until Solid
Place the tray flat in the freezer for at least 4–6 hours, or overnight until the cubes are rock hard.
Once solid, pop the basil-oil cubes out of the tray and transfer them to a zip-top bag or airtight container.
Label the bag with the date and use them within 6 months for the best quality.
Tips For The Best Results When You Freeze Basil In Olive Oil Without Blanching
There are a few little tricks that separate good frozen basil from great frozen basil.
Keep these in mind and your basil will taste like it was just plucked from the garden.
1. Use Leafy, Not Woody, Basil Stems
Only freeze the leaves and tender upper stems.
Woody, thick stems don’t soften well and can be bitter.
So strip the leaves off and reserve the stems for stocks if you like, but don’t toss them in the olive oil.
2. Choose a Mild or Robust Olive Oil
The olive oil you use will flavor the basil, so pick one you enjoy eating.
A mild oil works well for delicate uses like salad dressings, while a robust, peppery oil adds a punch to pasta sauces.
If you want a neutral taste, you can also freeze basil in olive oil without blanching using a light, refined olive oil.
3. Add Garlic or Lemon for a Flavor Boost
Before freezing, you can mix in minced garlic, lemon zest, or even a pinch of chili flakes.
This creates instant flavor bombs for quick weeknight dinners.
Just remember that these additions will infuse the oil, so keep the combos simple and versatile.
4. Don’t Skip the Air-Tight Storage
After the cubes are frozen, squeeze as much air out of the freezer bag as possible.
Oxygen is the enemy of frozen basil, even when it’s coated in oil.
With proper storage, you’ll enjoy that fresh flavor for months.
So, How Do You Freeze Basil In Olive Oil Without Blanching?
You freeze basil in olive oil without blanching by simply chopping fresh, dry leaves, packing them into ice cube trays, and covering them completely with olive oil before freezing.
No hot water, no ice baths, and no special equipment.
This method preserves the color, aroma, and flavor of your basil, making it a reliable pantry hack for year-round cooking.
Once you try this, you’ll never worry about a glut of basil going to waste again.
Pop a cube into tomato sauce, throw one in a pan with shrimp, or melt it over roasted veggies for an instant herb-kissed finish.
The next time your garden overproduces, you’ll know exactly what to do.
Freeze basil in olive oil without blanching, and you’ll always have a taste of summer ready in your freezer.
