Why You’ll Love Making Basil Mayonnaise
Learning how to make basil mayonnaise from scratch is a game changer for your meals.
The homemade version is far more flavorful than anything you’ll find in a store-bought jar.
Plus, you control the quality of the oil and the amount of garlic and lemon, which means every batch of basil mayonnaise can be tailored exactly to your taste.
1. Fresh Flavor That Beats Store-Bought
Fresh basil leaves bring a sweet, peppery, and slightly minty note that dried herbs just can’t replicate.
When you make basil mayonnaise at home, the herb’s essential oils are released right into the emulsion.
That’s why this basil mayonnaise tastes so much brighter than anything from a bottle.
2. Quick and Easy to Prepare
Don’t be intimidated by the idea of making mayo from scratch.
With an immersion blender or a food processor, you can have basil mayonnaise ready in less than five minutes.
The process is forgiving, and even if you’ve never made mayonnaise before, this basil mayonnaise recipe will work beautifully for you.
3. Endless Versatility
Once you know how to make basil mayonnaise, you’ll find a hundred uses for it.
Use it as a spread on tomato sandwiches, a dip for crispy fries, or a topping for grilled chicken.
You can even thin it with a little buttermilk to make a fantastic basil mayonnaise salad dressing.
How to Make Basil Mayonnaise from Scratch
Here is the step-by-step method for making basil mayonnaise in your own kitchen.
The key to success is having all your ingredients at room temperature.
Your Ingredient Checklist
You’ll need one large egg yolk, one teaspoon of Dijon mustard, one tablespoon of fresh lemon juice, one clove of garlic (minced), half a cup of fresh basil leaves (packed), and one cup of neutral oil like avocado or grapeseed oil.
Salt and a pinch of white pepper round out the flavors.
Step 1: Blend the Basil and Acid
Start by adding the basil leaves, lemon juice, garlic, and mustard to your blender jar.
Blend these ingredients until the basil is finely chopped and you have a green paste.
This step ensures the basil is evenly distributed throughout your final batch of basil mayonnaise.
Step 2: Add the Egg Yolk
Now add the room-temperature egg yolk to the basil mixture.
Blend for about ten seconds until everything is fully combined.
The mustard here acts as an emulsifier, which is why this basil mayonnaise won’t break or separate.
Step 3: Slowly Stream in the Oil
This is the most important step in learning how to make basil mayonnaise.
With your blender running on low speed, begin adding the oil in a very thin, steady stream.
Think of it like slowly pouring a thread of oil into the mixture.
If you pour too quickly, the emulsion can break, so take your time.
Watch as the mixture transforms from a loose liquid into a thick and creamy basil mayonnaise.
Step 4: Finish and Season
Once all the oil is in and your basil mayonnaise is thick and glossy, stop the blender.
Taste it and add salt and white pepper as needed.
If you like a thinner consistency, you can whisk in a teaspoon of warm water at the end.
Transfer your basil mayonnaise to a jar and refrigerate it.
Pro Tips for the Perfect Basil Mayonnaise
Even though this recipe is simple, a few extra tips will guarantee you make basil mayonnaise like a pro.
Use a Neutral Oil
For the best flavor, choose a mild oil like avocado, canola, or a light olive oil.
Extra-virgin olive oil can be too bitter and will overpower the delicate basil flavor in your basil mayonnaise.
If you do use olive oil, try mixing it half and half with a neutral oil.
Blanch the Basil for a Brighter Color
One trick to keep your basil mayonnaise a vibrant green is to blanch the basil first.
Drop the leaves in boiling water for five seconds, then plunge them into ice water.
Pat them dry before blending. This stops the oxidation process that can turn your basil mayonnaise brown.
Fix a Broken Mayonnaise
If your basil mayonnaise does separate, don’t panic.
You can fix it by placing a fresh egg yolk in a clean bowl.
Then whisk in the broken mixture, a few drops at a time, until the emulsion comes back together.
Delicious Variations of Basil Mayonnaise
Once you’ve mastered the basic how to make basil mayonnaise method, get creative with add-ins.
1. Garlic Basil Mayonnaise
Add an extra clove of roasted garlic for a sweeter, mellower flavor.
This version of basil mayonnaise is incredible on burgers or stirred into pasta salads.
2. Lemon Basil Mayonnaise
Increase the lemon juice by another half tablespoon and add a teaspoon of lemon zest.
This bright and tangy basil mayonnaise is perfect for seafood like crab cakes or fried fish.
3. Spicy Basil Mayonnaise
Mix in a teaspoon of sriracha or a pinch of cayenne pepper.
The heat balances beautifully with the fresh basil, and this spicy basil mayonnaise is fantastic on tacos.
4. Vegan Basil Mayonnaise
You can still make basil mayonnaise without eggs.
Use a quarter cup of aquafaba (the liquid from a can of chickpeas) instead of the egg yolk.
Follow the same steps of adding acid, basil, and then oil slowly.
The result is a creamy and plant-based basil mayonnaise that works just as well.
How to Store Basil Mayonnaise
Proper storage keeps your homemade basil mayonnaise safe and tasty.
Store it in an airtight glass jar in the refrigerator.
Because it contains fresh herbs and raw egg, it will last for about three to four days.
Never leave basil mayonnaise out at room temperature for more than two hours.
For longer storage, you can freeze basil mayonnaise in an ice cube tray.
Once frozen, pop the cubes into a freezer bag and use them within a month.
Just thaw them in the fridge overnight before using.
