How To Make Basil Oil (Easy Homemade Basil-Infused Oil)

Fresh basil has a way of taking over the garden—and the refrigerator—during the summer months. While pesto may be the first thing that comes to mind, basil oil is another simple and delicious way to put those fragrant leaves to good use. With its vibrant green color and fresh herb flavor, basil oil can instantly elevate everything from grilled vegetables and salads to pasta, soups, pizza, and even avocado toast.

One of my favorite things about basil oil is how versatile it is. A quick drizzle can transform a simple dish into something that feels restaurant worthy. It’s also a great way to preserve some of that fresh basil flavor before the season comes to an end. By briefly blanching the basil before blending, you’ll achieve a brighter green color that makes this oil just as beautiful as it is flavorful.

Ingredients: Basil Oil

• Fresh basil leaves (1 packed cups): The star of the recipe. Summer basil provides a bright, peppery, slightly sweet flavor and a beautiful green color.
• Extra-virgin olive oil (1/2 cup): Serves as the base of the oil and helps carry the fresh basil flavor throughout the recipe.
• Ice water: Used to quickly cool the basil after blanching, helping preserve its vibrant green color.
• Pinch of salt (optional): Can help enhance the flavor of the basil.

Instructions: How To Make Homemade Basil Oil

1. Bring a small pot of water to a boil and prepare a bowl of ice water nearby.
2. Add the basil leaves to the boiling water and blanch for about 10 seconds, just until the leaves wilt and turn bright green.
3. Transfer immediately the basil to the ice water bath to stop the cooking process. Once cooled, drain well and gently squeeze out excess moisture using a clean kitchen towel or paper towels.
4. Place the blanched basil, olive oil, and optional pinch of salt into a blender or food processor.
5. Blend until completely smooth, about 1–2 minutes. The mixture should be vibrant green and fully combined.

At this point, you have two options:

For a Smooth Basil Oil

Pour the blended mixture through a fine-mesh strainer, cheesecloth, or coffee filter into a clean jar or container. Allow the oil to strain naturally, pressing lightly if needed. Discard the solids.

For a Rustic Basil Oil

Skip the straining step and store the blended mixture as is. The small flecks of basil provide additional texture and concentrated basil flavor, making it ideal for spooning over vegetables, pasta, and grain bowls.

Transfer the basil oil to an airtight container and refrigerate until ready to use.

Ways to Use Basil Oil

This basil oil is incredibly versatile and can be used in countless ways throughout the summer:

• Drizzle over sliced tomatoes and fresh mozzarella
• Spoon onto grilled vegetables
• Finish soups with a swirl of basil oil
• Toss with warm pasta
• Drizzle over pizza
• Add to grain bowls and salads
• Use as a finishing oil for grilled chicken or fish
• Spread over toasted bread or avocado toast

Why Blanch the Basil?

Blanching may seem like an extra step, but it’s worth the effort. The quick dip in boiling water helps preserve the chlorophyll in the basil leaves, resulting in a brighter, more vibrant green oil. Without blanching, basil oil can darken more quickly and lose some of its visual appeal. The result is an oil that’s as beautiful on the plate as it is flavorful.

A Simple Way to Preserve Summer Flavor

If you’ve ever found yourself with more basil than you know what to do with, this recipe is the answer. Basil oil captures the essence of summer in a simple, versatile condiment that can be used throughout the week. Whether you strain it for a smooth finish or leave the basil intact for a more rustic texture, it’s an easy way to make the most of one of summer’s most beloved herbs.
