In this post, we’ll walk you through the best methods for making basil olive oil, the key ratios for a balanced infusion, and how to store your homemade basil olive oil so it stays fresh and flavorful for weeks.
 
Let’s get right into it.
 

How Do You Make Basil Olive Oil: The Core Method

The most direct answer to how do you make basil olive oil is to combine fresh basil with good olive oil, then let the flavors meld through gentle heat or time.
 
The magic happens because basil’s essential oils are fat-soluble, meaning they dissolve beautifully into olive oil, releasing that aromatic, peppery, and slightly sweet character.
 
Here’s the breakdown of the main techniques so you can pick the one that fits your schedule and kitchen setup.
 

1. The Cold Infusion Method for Basil Olive Oil

Cold infusion is the purest way to make basil olive oil because it doesn’t involve heat, which can dull the basil’s freshness.
 
Start with thoroughly washed and completely dried basil leaves, any moisture will encourage spoilage and cloudy results.
 
Gently bruise the leaves with your fingers or the back of a spoon to release their natural oils before placing them in a clean glass jar.
 
Pour your extra virgin olive oil over the basil, ensuring the leaves are fully submerged, then seal the jar tightly.
 
Store the jar in a cool, dark place for one to two weeks, shaking it gently every day to encourage the infusion process.
 
After that, strain the basil olive oil through a fine mesh strainer lined with cheesecloth, and you’ll have a delicate, green-tinted oil ready to use.
 

2. The Warm Infusion Method for Basil Olive Oil

If you’re short on time, the warm infusion method is your best bet because it speeds up the process dramatically.
 
To make basil olive oil this way, gently heat your olive oil in a saucepan over low heat, being careful not to let it smoke or bubble.
 
Add your bruised basil leaves to the warm oil and let them steep for about 15 to 20 minutes, stirring occasionally.
 
The warmth helps the basil release its flavor into the oil much faster than the cold method.
 
Once the oil has cooled completely, strain it and bottle your basil olive oil in a sterilized glass container.
 
Just remember that warm infusion can slightly cook the basil, so the final flavor will be a bit more mellow and toasted compared to the cold method.
 

3. The Food Processor or Blender Quick Method

For an instant basil olive oil, you can actually blend the basil with oil to create a vibrant, emulsified version that’s perfect for dressings and marinades.
 
Add fresh basil leaves and a neutral olive oil to a blender, then pulse until the leaves are finely chopped, but not completely pureed if you don’t want a thick pesto-like texture.
 
This basil olive oil is more of a suspension than a pure infusion, so it will separate over time, but you can shake it before use.
 
This method also works wonderfully if you want a stronger basil presence right away, and you don’t mind straining it later for a smoother finish.
 

Tips for the Best Basil Olive Oil Flavor and Shelf Life

To truly master how do you make basil olive oil, you need to focus on quality ingredients and smart storage habits.
 
The basil you choose plays a huge role, as older or wilted leaves will produce a less vibrant basil olive oil.
 
You should always pick fresh, young basil leaves for the brightest flavor.
 
Here are some pro tips to make basil olive oil like a seasoned home cook.
 

1. Use a High-Quality Extra Virgin Olive Oil

The olive oil you use is just as important as the basil itself, so never skimp on this component.
 
A fruity, slightly peppery extra virgin olive oil will complement the basil rather than overpower it.
 
If you use a cheap, overly bitter oil, your basil olive oil will inherit those harsh notes.
 
Taste your oil before you start and make sure it’s something you’d happily dip bread in on its own.
 

2. Dry Basil Leaves Thoroughly

Moisture is the enemy of homemade basil olive oil because water promotes bacterial growth and rancidity.
 
After washing your basil, pat the leaves dry with a clean kitchen towel or use a salad spinner to remove excess water.
 
Even tiny droplets can cause your oil to cloud and potentially spoil faster.
 
Taking this extra step will make your basil olive oil last much longer and taste cleaner.
 

3. Store Your Basil Olive Oil Properly

Once you’ve made your basil olive oil, how you store it determines its longevity and freshness.
 
Keep the oil in a dark glass bottle or jar, as light and heat degrade both the olive oil and the basil flavor over time.
 
Store it in a cool pantry or cupboard, away from the stove and direct sunlight.
 
For the cold infusion method, your basil olive oil can last up to two to three weeks when stored this way.
 
Always refrigerate your basil olive oil if you plan to keep it longer than that, just remember it may solidify slightly, so let it come to room temperature before use.
 

4. Strain the Oil Well for Clarity

Leaving bits of basil in your oil might look rustic, but those tiny particles can cause the oil to go rancid more quickly.
 
Strain your basil olive oil through a fine mesh sieve lined with double-layered cheesecloth to capture all the sediment.
 
You can strain it once, then again after a day to catch any remaining particles that settle at the bottom.
 
A clean, clear basil olive oil not only looks more professional, but it also tastes fresher and stores better.
