Making basil infused olive oil is a simple kitchen project that rewards you with a vibrant, aromatic oil perfect for drizzling, dipping, and cooking.
You can make basil infused olive oil at home with just two main ingredients, fresh basil and good quality olive oil, plus a little patience.
It’s one of those homemade staples that instantly elevates salads, pastas, and grilled vegetables with a fresh, herby punch.
In this post, we’ll walk through the best methods for making basil infused olive oil, share tips for flavor and safety, and answer common questions so you get it right every time.
Let’s dive into the wonderful world of homemade basil infused olive oil.
Why Make Basil Infused Olive Oil at Home
Making basil infused olive oil at home beats store-bought versions in freshness, flavor intensity, and cost.
You control the quality of the olive oil and the amount of basil, so you can tailor it exactly to your taste.
Plus, homemade basil infused olive oil makes a thoughtful gift or a beautiful addition to your own kitchen pantry.
Store-bought infused oils often sit on shelves for months, losing their vibrant aroma, but a fresh batch delivers that garden-fresh essence immediately.
It’s also a great way to use up an abundance of basil from your garden before it goes to seed.
1. Fresh Basil Brings the Best Flavor
The star of basil infused olive oil is, of course, the basil itself.
Fresh basil leaves, preferably from your own plant or a local farmer’s market, give the oil a bright, slightly sweet, and peppery character.
Dried basil just doesn’t compare here because it lacks the essential oils that infuse into the olive oil during the process.
You’ll want to use the freshest leaves you can find, washing them gently and patting them completely dry before starting.
Water is the enemy of infused oil because it can promote bacterial growth and spoilage.
2. Quality Olive Oil Matters
Your basil infused olive oil is only as good as the base oil you start with, so don’t skimp here.
Choose a mild, fruity extra virgin olive oil that won’t overpower the delicate basil flavor.
A robust, peppery olive oil can compete with the basil, while a neutral one allows the herb to shine through beautifully.
You could also use a lighter olive oil if you prefer a subtler infusion, but extra virgin adds its own health benefits and complexity.
The goal is a balanced basil infused olive oil where neither ingredient dominates the other.
How to Make Basil Infused Olive Oil: Step-by-Step Methods
Now let’s get into the actual steps for making basil infused olive oil, and there are two main approaches to try.
The first method is the cold infusion, which is quick and preserves the bright, fresh flavor of the basil perfectly.
The second is the warm infusion, which extracts more flavor but requires careful temperature control for safety.
We’ll cover both so you can decide which fits your kitchen style and needs.
1. Cold Infusion Method for Basil Infused Olive Oil
Cold infusion is my favorite way to make basil infused olive oil because it’s simple and keeps the basil tasting just-picked.
Start with about one cup of fresh basil leaves, washed and thoroughly dried with paper towels or a salad spinner.
Roughly tear or chop the leaves to release their oils, then place them in a clean, dry glass jar.
Pour one to two cups of extra virgin olive oil over the basil until it’s fully submerged.
Seal the jar tightly and place it in a cool, dark spot like a pantry or cupboard for at least 48 hours.
For a stronger basil infused olive oil, you can let it infuse for up to a week, shaking the jar gently once a day to mix.
The longer it sits, the more intense the basil flavor becomes, so taste it after two days and decide if you want more.
Once it reaches your preferred taste, strain the oil through a fine-mesh sieve lined with cheesecloth into a clean bottle or jar.
Press the leaves gently to extract every last drop of oil, then discard the basil.
Store your basil infused olive oil in the fridge and use it within two to three weeks for the freshest flavor.
2. Warm Infusion Method for Faster Results
If you want basil infused olive oil in under an hour, the warm method is your answer.
Blanch the basil leaves in boiling water for about 10 seconds, then immediately transfer them to an ice water bath.
This quick blanch kills any surface bacteria and helps the leaves retain their bright green color in the oil.
Pat the blanched basil dry completely, then gently crush the leaves with your hands or a mortar and pestle.
Combine the crushed basil with olive oil in a small saucepan over very low heat.
Heat the mixture gently to around 140–160°F (60–70°C), and maintain that temperature for about 5–10 minutes.
Do not let the oil boil, because high heat will turn the basil bitter and degrade the olive oil’s quality.
Remove the saucepan from the heat and let the basil infused olive oil cool completely at room temperature.
Strain the oil through cheesecloth as you would with the cold method, discarding the basil solids.
This warm basil infused olive oil is ready to use right away, though it won’t have the same raw, fresh aroma as the cold version.
It’s a great option when you’re short on time but still want that lovely homemade touch.
Flavor Variations for Basil Infused Olive Oil
Once you’ve mastered the basic basil infused olive oil, feel free to get creative with additions.
The beauty of homemade infusions is that you can customize them endlessly to suit your dishes and preferences.
Here are a few simple ideas to take your basil infused olive oil to the next level.
1. Add Garlic for a Savory Punch
Add a few peeled, lightly smashed garlic cloves to your jar along with the basil in the cold infusion method.
The garlic will infuse alongside the basil, creating a savory, aromatic oil perfect for pasta and bread dipping.
Be careful with garlic in oil because it carries a risk of botulism if stored improperly, so always keep it refrigerated.
Use garlic basil infused olive oil within one week and discard any leftover oil that sits out at room temperature.
2. Citrus Zest Brightens Things Up
Add a strip of fresh lemon zest or orange zest to your basil infused olive oil for a bright, sunny note.
The citrus oils will meld with the basil, creating a refreshing dressing base or a finishing drizzle for seafood.
Make sure to wash the fruit well and dry the zest completely before adding it to the oil.
You can also add a pinch of chili flakes for a gentle heat that pairs beautifully with the basil.
Safety Tips for Storing Basil Infused Olive Oil
Homemade basil infused olive oil is perishable, and proper storage is crucial to keep it safe and tasty.
The main concern with infused oils is the risk of botulism, especially when garlic or fresh herbs are used.
Always store your basil infused olive oil in the refrigerator, not at room temperature, to inhibit bacterial growth.
Use a clean, dry spoon or bottle each time you access the oil to avoid introducing moisture or contaminants.
For cold infusion, stick to a two to three week shelf life, while warm infused oil can last a bit longer if kept cold.
Never store basil infused olive oil for months like you would a commercial shelf-stable product, because homemade versions don’t have preservatives.
If you notice any off smells, cloudiness, or mold, toss the oil immediately and start fresh.
It’s always better to make small batches that you’ll use quickly rather than large quantities that might go bad.
So, How Do You Make Basil Infused Olive Oil?
You make basil infused olive oil by combining fresh basil with olive oil and letting time or gentle heat do the work.
The cold infusion method involves steeping dried basil leaves in oil for days, while the warm method uses low heat for quick results.
Both approaches yield a delicious basil infused olive oil that brightens up your meals with a fresh, herby essence.
Whether you’re drizzling it over caprese salad, tossing it with roasted vegetables, or dipping crusty bread, this homemade oil is a game changer.
So grab some fresh basil and good olive oil, and start infusing your way to a more flavorful kitchen today.
