How Do You Make Basil Infused Olive Oil? Step-by-Step Methods
There are two main ways to make basil infused olive oil: the cold infusion method and the gentle heat method.
Both work well, but they produce slightly different results, so let’s break them down.
Method 1: The Cold Infusion Method
The cold infusion method is the safest approach, especially if you plan to store your oil for more than a few days.
Here’s how you make basil infused olive oil using cold infusion: first, wash and completely dry your basil leaves.
Moisture is the enemy here, because any water left on the leaves can lead to bacterial growth.
Gently bruise the leaves with your fingers to release their essential oils, then place them in a clean glass jar.
Pour your favorite olive oil over the basil until it’s completely submerged.
Seal the jar and let it sit in a cool, dark place for about one to two weeks.
You can shake the jar gently every day to help the flavors mingle.
After the steeping period, strain out the basil leaves and transfer the oil to a clean bottle.
This method yields a light, fresh basil infused olive oil with a delicate grassy flavor.
Method 2: The Gentle Heat Method
The gentle heat method is quicker and gives you a more intense basil infused olive oil in just a few hours.
To make basil infused olive oil with heat, start by washing and drying your basil thoroughly.
Place the basil and olive oil in a small saucepan over the lowest possible heat.
Warm the mixture gently for about 15 to 20 minutes, making sure the oil never sizzles or bubbles.
You want the oil to feel warm but not hot to the touch.
Once you smell the basil strongly, remove the pan from the heat and let it cool completely.
Strain the oil through a fine mesh sieve or cheesecloth into a sterilized bottle.
This method is perfect when you need basil infused olive oil on the same day.
Choosing the Right Ingredients to Make Basil Infused Olive Oil
The quality of your basil infused olive oil depends almost entirely on the quality of your ingredients.
Here’s what you need to pay attention to when you make basil infused olive oil.
1. Pick the Best Olive Oil
Use a mild, fruity extra virgin olive oil rather than a super peppery or bitter one.
The olive oil should complement the basil, not overpower it.
A good quality olive oil will make your basil infused olive oil taste smooth and luxurious.
2. Use Fresh, Dry Basil Leaves
Fresh basil leaves are non-negotiable when you make basil infused olive oil.
And they must be bone-dry before they touch the oil.
Pat them gently with a kitchen towel and let them air dry for an hour if you have the time.
Wet basil will introduce water into your oil, which can cause spoilage and rancidity.
Important Safety Tips When You Make Basil Infused Olive Oil
While making basil infused olive oil is easy, there is one major safety concern you have to know about.
Fresh garlic and fresh herbs in oil can create the perfect environment for botulism bacteria if not handled correctly.
1. The Botulism Risk with Fresh Herbs
When you make basil infused olive oil with fresh basil, the risk is much lower than with garlic, but it’s still there.
Fresh herbs can harbor Clostridium botulinum spores, which thrive in oxygen-free, low-acid environments like oil.
To minimize this risk, always keep your infused oil refrigerated and use it within a week or two.
If you want to store it longer, freeze the basil infused olive oil in ice cube trays.
2. Acidify the Basil for Long-Term Storage
If you want to make basil infused olive oil that lasts for months without freezing, you can add a bit of acid.
A splash of lemon juice or white vinegar lowers the pH and makes it harder for bacteria to grow.
Some recipes call for steeping the basil in a vinegar solution first, but honestly, that changes the flavor profile.
For most home cooks, the freezer method is the safest and easiest way to preserve basil infused olive oil.
So, How Do You Make Basil Infused Olive Oil and Store It Properly?
You make basil infused olive oil by combining fresh, dry basil with good olive oil, using either cold or gentle heat infusion.
The cold method takes longer but gives you a fresher, more delicate basil infused olive oil.
The heat method is quicker and yields a deeper, more robust basil infused olive oil that’s ready in a few hours.
Always dry your basil completely, keep the oil away from light and heat, and refrigerate your final product.
So, how do you make basil infused olive oil work for your kitchen?
Start with a small batch, taste it, and adjust the basil-to-oil ratio to your liking.
Once you’ve mastered the basics, you can experiment with adding other herbs like thyme or rosemary.
Making basil infused olive oil is a rewarding, delicious project that will add a fresh burst of summer to any dish.
Now go grab some basil and a bottle of olive oil, because you’re fully equipped to make basil infused olive oil like a pro.
Enjoy every last drop.
