Basil oil is a vibrant, aromatic addition that can elevate everything from salads and pastas to grilled veggies and even desserts. Making your own basil oil at home is easier than you might think, and it’s a fantastic way to capture the fresh, sweet, and slightly peppery essence of basil in a versatile, shelf-stable form. Whether you want to drizzle it over dishes, use it in dressings, or add a fragrant touch to your cooking, this guide will walk you through how to make basil oil step-by-step.
What Is Basil Oil and Why Make It?
Basil oil is an infused oil made by blending fresh basil leaves with a neutral or mild-flavored oil, such as olive or grapeseed oil. The result is a beautifully green, flavorful oil that carries the essence of basil in a concentrated form.
Benefits of basil oil:
– Adds fresh, herbal flavor and aroma to dishes
– Contains antioxidants and anti-inflammatory properties
– Can be used in cooking, skin care, and aromatherapy
– Easy to make with simple ingredients and equipment
Homemade basil oil is fresher and more vibrant than store-bought versions, and you control the ingredients and intensity of flavor.
Ingredients and Tools You’ll Need
– Fresh basil leaves (about 1 cup tightly packed or one bunch)
– Oil: Extra virgin olive oil for flavor, or grapeseed/refined oil for a lighter taste
– Optional: garlic, salt, lemon juice, or pepper for added flavor
– Blender or food processor
– Large pot for blanching
– Ice bath (bowl with ice water)
– Cheesecloth or fine strainer (optional, for a clear oil)
– Airtight glass container for storage
Step-by-Step Instructions for Making Basil Oil
1. Prepare the Basil
Start by washing your fresh basil leaves thoroughly. Tear the leaves off the stems, discarding the stems or saving them for other uses.
2. Blanch the Basil
Bring a large pot of water to a rolling boil. Quickly blanch the basil leaves by submerging them in boiling water for about 10 to 30 seconds. This step helps set the bright green color and softens the leaves without cooking them fully.
Immediately transfer the basil to an ice bath to stop the cooking process and preserve the vibrant color.
3. Dry the Basil
Remove the basil from the ice bath and squeeze out as much water as possible. Pat the leaves dry with paper towels or a clean kitchen towel. This step is crucial to avoid diluting the oil and to prevent spoilage.
4. Blend the Basil and Oil
Place the blanched and dried basil leaves in a blender. Add your chosen oil—typically about 1 cup of oil for every cup of basil leaves.
Blend until the mixture is smooth and vibrant green. For extra flavor, you can add a pinch of salt, a clove of garlic, or a splash of lemon juice before blending.
5. Strain the Oil (Optional)
If you prefer a clear, smooth basil oil without any solids, strain the blended mixture through a cheesecloth or fine mesh strainer. Press or squeeze to extract as much oil as possible. The strained oil will be bright green and perfect for drizzling or garnishing.
6. Store Properly
Pour the basil oil into a clean, airtight glass container. Store it in the refrigerator and use within 2-5 days to ensure freshness and safety. Because basil oil is fresh and contains water from the leaves, it has a short shelf life and should be consumed quickly.
Tips for the Best Basil Oil
– Use fresh, vibrant basil leaves for the best flavor and color.
– Blanching is key to keeping the oil bright green and fresh-tasting.
– Dry the basil leaves thoroughly to prevent water in the oil, which can cause spoilage.
– Use a mild-flavored oil like grapeseed if you want the basil flavor to shine without olive oil’s stronger taste.
– Blend just enough to combine; over-blending can bruise the leaves and darken the oil.
– Store in the fridge and use quickly to avoid botulism risks associated with fresh herb oils.
Creative Ways to Use Basil Oil
– Drizzle over fresh mozzarella, tomatoes, and salads for a classic Caprese twist
– Add to pasta dishes or risottos for a fresh herbal kick
– Use as a dipping oil for crusty bread or roasted vegetables
– Stir into soups or sauces for added aroma and flavor
– Garnish grilled meats or fish for a colorful finish
– Mix into vinaigrettes or homemade mayonnaise for a basil-infused dressing
Basil oil is a simple yet impressive way to bring the fresh taste of basil into your kitchen year-round. With just a handful of ingredients and a few easy steps, you can create a versatile, flavorful oil that brightens up any dish.
