If you’ve ever wondered how to extract oil from basil right in your own kitchen, you’re in the right place.
 
This fragrant herb isn’t just for pesto or garnishing your pasta, it’s packed with aromatic compounds that make a wonderful oil for cooking, skincare, and natural remedies.
 
In this post, we’ll walk you through the different ways to extract oil from basil, what you need, and the pros and cons of each method.
 
Let’s dive into the world of basil oil extraction and get you set up for success.
 

Why You Might Want To Extract Oil From Basil

There are several reasons you might want to extract oil from basil at home, and it’s easier than you think.
 
Basil oil is a concentrated liquid that captures the herb’s sweet, peppery, and slightly minty aroma.
 
When you extract oil from basil leaves, you’re pulling out the volatile compounds like linalool and estragole, which give basil its signature scent.
 
These compounds are what make basil oil so valuable in aromatherapy, natural cleaning products, and even homemade salad dressings.
 
If you grow your own basil, you probably have more leaves than you know what to do with, so learning how to extract oil from basil is a brilliant way to preserve the harvest.
 
Plus, making your own oil means you control the quality and avoid any synthetic additives you might find in store-bought versions.
 
Let’s look at the main methods to get that liquid gold out of your basil.
 

How To Extract Oil From Basil: The Steam Distillation Method

Steam distillation is the gold standard when you want to extract oil from basil that’s pure and potent.
 
This is the same method used by commercial producers to make essential oils, and while it requires a bit of equipment, the results are amazing.
 
Here’s how it works and why it’s the best way to extract oil from basil if you’re serious about quality.
 

1. Gather Your Equipment

To extract oil from basil using steam, you’ll need a few specific items that might seem a little lab-like.
 
First, grab a large pot with a tight-fitting lid and a heatproof bowl that floats inside the pot.
 
You’ll also want a steamer basket or a metal strainer to hold the basil leaves above the water.
 
And finally, you need a glass collecting vial and some ice cubes to help condense the steam.
 
If you don’t have these at home, you can often find a home distillation kit online for under fifty dollars.
 
It’s a worthwhile investment if you plan to extract oil from basil regularly.
 

2. Prep The Basil Leaves

The freshness of your basil matters a lot when you want to extract oil from basil leaves.
 
Harvest your basil in the morning after the dew has dried, as that’s when the oil content is highest.
 
Rinse the leaves gently and pat them completely dry because any excess water will just dilute your steam.
 
Then, roughly chop or bruise the leaves to help release more of the aromatic compounds during distillation.
 
For best results, use about two to three cups of packed basil leaves for a single batch.
 
The more leaves you use, the more oil you’ll get, but you’ll also need a bigger pot.
 

3. Set Up The Distillation Process

Place your heatproof bowl in the center of the pot, then add the basil leaves around it.
 
Pour water into the pot, making sure the water level stays below the top of the bowl so it doesn’t spill in.
 
Turn the heat on medium-high and bring the water to a gentle boil, then reduce to a simmer.
 
Put the lid on upside down so the steam hits the lid and drips down into your bowl.
 
Place ice cubes on top of the lid to cool the steam, which speeds up condensation.
 
As the steam rises, it passes through the basil, captures the oils, and then drips into the bowl as a watery mix.
 
After about thirty to forty-five minutes, you’ll see a thin layer of yellow oil floating on top of the water in the bowl.
 

4. Separate The Oil

Now comes the most delicate part of extracting oil from basil, separating the oil from the hydrosol.
 
Carefully remove the bowl from the pot and let the liquid cool to room temperature.
 
Use a pipette or a small glass dropper to suction off the thin oil layer from the surface.
 
Technically, basil oil is lighter than water, so it will sit right on top.
 
Transfer the oil into a dark glass bottle and store it in a cool, dark place.
 
The remaining water is a fragrant basil hydrosol that you can use as a facial toner or room spray.
 

How To Extract Oil From Basil Using A Carrier Oil Infusion

If you want a simpler method that doesn’t require any special equipment, then a carrier oil infusion is your best bet.
 
This method doesn’t produce a pure essential oil, but it does extract oil from basil leaves into a base oil like olive or sunflower.
 
The result is a flavorful infused oil that’s perfect for cooking, massage, or adding to homemade soap.
 
Here’s how to do it step by step.
 

1. Choose Your Carrier Oil

The first step to infuse and extract oil from basil is picking a good carrier oil.
 
Extra-virgin olive oil is the classic choice because it has a neutral taste that doesn’t overpower the basil.
 
You can also use grapeseed oil, avocado oil, or even coconut oil if you prefer a slightly sweeter finish.
 
Make sure your oil is high quality and cold-pressed for the best flavor and shelf life.
 
You’ll need about one cup of carrier oil for every cup of packed basil leaves.
 
This ratio gives you a nice balance between basil flavor and oil consistency.
 

2. Dry The Basil Slightly

To prevent mold and rancidity, you should dry your basil leaves for a few hours before starting the infusion.
 
Spread the washed leaves on a clean kitchen towel and let them air dry until they feel slightly wilted.
 
This step removes excess moisture, which is the enemy of any infused oil.
 
Once they’re dry, bruise the leaves with your hands to release more of their essential oils.
 
Then, place the basil in a clean, dry glass jar with a tight-fitting lid.
 

3. Warm The Oil And Combine

Gently warm your carrier oil in a small saucepan over low heat until it’s just warm to the touch, not hot.
 
Pour the warm oil over the basil leaves in the jar, making sure they’re completely submerged.
 
Use a chopstick to stir the leaves and release any trapped air bubbles.
 
Then, seal the jar and place it in a sunny windowsill for one to two weeks.
 
Shake the jar gently every day to help the basil release its oils into the carrier oil.
 

4. Strain And Store

After the waiting period, it’s time to strain out the leaves and finish your basil oil.
 
Place a fine-mesh strainer lined with cheesecloth over a clean bowl.
 
Pour the infused oil through the strainer, pressing on the leaves to get every last drop.
 
Now you’ve successfully managed to extract oil from basil using the infusion method.
 
Transfer the oil into a dark glass bottle, label it with the date, and store it in the fridge for up to three months.
 

Tips To Get The Most Basil Oil Yield

Whether you’re using steam or infusion, you’ll get a better yield if you follow a few simple tricks.
 
First, always use fresh, high-quality basil because older leaves lose their volatile oils over time.
 
Second, bruise the leaves thoroughly before you start, since this breaks the cell walls and releases more oil.
 
Third, keep your temperatures low and slow, because heat that’s too high will destroy the delicate compounds.
 
And fourth, don’t skip the drying step in the infusion method because moisture is your biggest risk for spoilage.
 
If you follow these tips, you’ll extract oil from basil that smells amazing and lasts a long time.
 
Remember that essential oil yields are small, so don’t be surprised if a whole pot of basil gives you just a teaspoon of oil.
 

So, How Do You Extract Oil From Basil?

You can extract oil from basil using steam distillation for a pure essential oil or a carrier oil infusion for a kitchen-friendly version.
 
Steam distillation is the best method when you want a concentrated oil for aromatherapy or natural remedies.
 
Carrier oil infusion is easier, cheaper, and perfect for cooking and topical use.
 
Both methods are totally doable at home with just a few ingredients and a little patience.
 
Now that you know how to extract oil from basil, you can turn your herb garden into a tiny apothecary.
 
So grab your basil, pick a method, and enjoy the amazing scent of homemade basil oil.
