Basil Vinaigrette Recipe | Easy Homemade Basil Dressing

Vibrant green Basil Vinaigrette in a small glass jar, smooth and glossy with an emulsified texture.

A great vinaigrette should taste like whatever herb it's built around, not like an afterthought. This Basil Vinaigrette Recipe puts fresh basil front and center, blended with shallot, Dijon mustard, and a good red wine vinegar into a smooth, emulsified dressing that stays vibrant green thanks to one simple trick: a quick blanch of the basil before blending.

Unlike a basic oil-and-vinegar shake, this vinaigrette is properly emulsified, meaning the oil and vinegar blend into a smooth, cohesive dressing that clings to greens instead of pooling at the bottom of the bowl. The shallot and Dijon mustard both help stabilize that emulsion while adding depth of flavor.

This is one of the easiest homemade basil vinaigrettes you can make with a few fresh ingredients and a blender. Whether you need a fresh basil vinaigrette for a simple summer salad or an easy basil vinaigrette to keep on hand as a marinade, this recipe delivers bright, balanced flavor every time.

Ingredients

1 ½ cups fresh basil leaves, packed
1 small shallot, roughly chopped
1 small clove garlic
1 teaspoon Dijon mustard
3 tablespoons red wine vinegar
⅔ cup extra-virgin olive oil
½ teaspoon salt, or to taste
¼ teaspoon black pepper
½ teaspoon granulated sugar (optional, to balance acidity)

Equipment Needed

Small pot, for blanching
Bowl of ice water
Blender or food processor
Measuring cups and spoons
Airtight jar or container, for storage

Step-by-Step Instructions

1. Prepare an Ice Bath

Fill a bowl with ice and cold water and set it aside. This will be used to quickly cool the basil after blanching.

2. Blanch the Basil

Bring a small pot of water to a boil. Add the basil leaves and blanch for about 10–15 seconds, just until they turn bright green and slightly wilted. Immediately transfer the basil to the ice water bath to stop the cooking process.

3. Drain and Dry the Basil

Once cooled, drain the basil and squeeze out as much excess water as possible using a clean towel or paper towels.

4. Combine the Base Ingredients

Add the blanched basil, shallot, garlic, Dijon mustard, and red wine vinegar to a blender or food processor. Blend until smooth.

5. Emulsify the Oil

With the blender running on low speed, slowly drizzle in the olive oil in a steady stream. This gradual addition helps the dressing emulsify into a smooth, cohesive vinaigrette rather than separating.

6. Season and Adjust

Add the salt, black pepper, and sugar, if using. Blend briefly to combine, then taste and adjust the seasoning as needed.

7. Store or Serve

Transfer the vinaigrette to an airtight jar or container. Serve immediately over your favorite salad, or refrigerate for later use.

Expert Tips

Don't skip the blanching step. This is the key to keeping the vinaigrette a vibrant green color instead of a duller, olive-green shade.
Work quickly when blanching. Basil only needs a brief dip in boiling water — leaving it in too long can cause it to lose flavor and turn mushy.
Squeeze out as much water as possible after blanching. Excess water can dilute the vinaigrette and throw off its consistency.
Add the oil slowly while blending. Pouring it in gradually, rather than all at once, is essential for achieving a smooth, stable emulsion.
Use a good-quality olive oil. Since this is a no-cook dressing base, the oil's flavor really comes through in the final product.
Taste before adding sugar. Depending on your vinegar's acidity, you may not need the optional sugar at all.

Common Mistakes to Avoid

Skipping the blanching step. Without it, the vinaigrette will still taste great but will turn a duller, less vibrant green color, especially after a day or two in the fridge.
Over-blanching the basil. Leaving it in boiling water for too long can cause it to lose its fresh flavor and turn an unappealing, overly soft texture.
Adding the oil too quickly. Pouring in all the olive oil at once instead of drizzling it in slowly can prevent the dressing from properly emulsifying, resulting in a separated, greasy texture.
Not squeezing out excess water from the basil. This can make the vinaigrette thinner and more diluted than intended.
Skipping the Dijon mustard. Beyond adding flavor, mustard acts as a natural emulsifier that helps keep the oil and vinegar blended together.

Variations

Lemon Basil Vinaigrette: Replace the red wine vinegar with fresh lemon juice for a brighter, more citrus-forward flavor.
Parmesan Basil Vinaigrette: Add 2 tablespoons of grated parmesan cheese for a slightly richer, savory twist.
Honey Basil Vinaigrette: Use honey instead of granulated sugar to balance the acidity with a more rounded sweetness.

Dairy-Free and Vegan Version: This recipe is naturally dairy-free and vegan as written.

What to Serve With It

A simple green salad with mixed greens, cherry tomatoes, and cucumber
Caprese salad, drizzled over fresh mozzarella and tomatoes
Grilled chicken, shrimp, or steak, used as a marinade or finishing sauce
A pasta salad, tossed in as a fresh, herby dressing
Roasted or grilled vegetables, drizzled on right before serving

Storage Instructions

Store the vinaigrette in an airtight jar or container in the refrigerator for up to 5 days. Thanks to the blanching step, the color will stay noticeably more vibrant over time compared to a vinaigrette made with raw basil.

Give the vinaigrette a good shake or stir before each use, as the oil and other ingredients may naturally separate slightly while sitting in the fridge.

This recipe is not recommended for freezing, as the texture and emulsion won't hold up well after thawing.

Reheating Tips

This vinaigrette is served cold or at room temperature and does not require reheating. If the olive oil solidifies slightly in the refrigerator, simply let the vinaigrette sit at room temperature for about 10–15 minutes and give it a good shake or stir before serving.

Frequently Asked Questions

Why do I need to blanch the basil first? Blanching briefly cooks the basil just enough to deactivate the enzymes that cause it to darken and turn an unappealing olive-green color once blended. This keeps the vinaigrette a much brighter, more vibrant green, especially after a day or two in storage.

Can I skip the blanching step? Yes, if you're short on time. The vinaigrette will still taste great, but it will likely turn a duller green color more quickly than the blanched version.

Why isn't my vinaigrette emulsifying properly? This usually happens when the oil is added too quickly. Make sure to drizzle it in slowly while the blender is running, and don't skip the Dijon mustard, which helps stabilize the emulsion.

How long does homemade basil vinaigrette last? Stored in an airtight container in the refrigerator, it will keep well for up to 5 days.

Can I use this as a marinade? Yes. This vinaigrette works well as a marinade for chicken, shrimp, or steak, adding bright, herby flavor before grilling or roasting.

Is this recipe vegan? Yes, this recipe is naturally vegan as written, with no dairy or animal products included.
