Mustard Aioli Sauce

Mustard aioli takes two the world’s best condiments and slaps them together: mustard and mayo. This zesty Mustard Aioli comes together in less than 5 minutes and is the perfect dipping sauce and sandwich topper for any meal or BBQ.

 

What is Aioli Sauce?

Aioli is popular in Mediterranean cuisine and is a sauce made of garlic, olive oil, lemon juice, and egg yolk, which makes it sneakily similar to a garlic mayo. It is the most popular in Spain, France and Italy.

This is also why you can make super easy aioli with just a store bought mayonnaise. You can also make your own mayonnaise super quick in a blender. You can use any type, but to be more authentic, look for one made with olive oil opposed to vegetable or other types of oil.

Best Type pf Mustard to Use

I like to use Dijon mustard, which is a French mustard from the Dijon region of France. The mustard seeds are more brown that yellow and produce a slightly subdued, but tangy mustard flavor.

You can also use specialty mustards like spicy brown mustard, horseradish, caramelized onion, sweet or even whole grain mustard.

Even though mustard is acidic, I still like to add lemon juice to brighten the flavor further. Salt is optional since it is also an ingredient in both mayonnaise and mustard. I only use a pinch anyhow.

You can even add a dab of honey or agave nectar to make a slightly sweet honey mustard aioli sauce. These are perfect for popcorn chicken or even as a basting sauce for grilled chicken or pork.

Mustard Aioli Ingredients

You will easily be able to find all of these simple ingredients at your local grocery store.

• Mayonnaise – Of course you can grab your favorite store-bought mayonnaise or make your own homemade mayonnaise!
• Fresh garlic – This isn’t a garlic aioli, but we do add some for flavor! You can mince garlic or freshly grate it.
• Mustard of choice – This really depends on taste. I like to use dijon mustard, but check the section above for alternatives.
• Lemon juice – Using fresh lemon juice is always preferable. Any citrus juice starts to lose flavor as soon as it is harvested. Fresh has much more flavor than bottled lemon juice and without any preservatives.
• Kosher salt – You only need a pinch. I like to use coarse kosher salt

Variations

There are many ways to make this delicious mustard aioli your own. Here are a few of our favorite suggestions:

• Worcestershire sauce – You can add a splash of worcestershire to this mustard sauce for even more tang and flavor.
• Spice – toss some cayenne pepper or crushed red pepper or even Old Bay to take the spice level up a notch.
• Pickle juice – spill a little pickle juice into this sauce to give it some tang. 

How to Make Mustard Aioli

Making the perfect sauce is as easy as one, two, three!

1. Combine ingredients. Combine all ingredients in a small bowl and whisk until combined.
2. Allow to chill. Chill for 30 minutes before serving. This allows the flavors of all the ingredients to marry together.

How to Use Mustard Aioli?

Homemade aioli is excellent as a dipping sauces or condiment to slather on sandwiches or burgers. You can dip olives, carrots or potato chips and even put a dollop on top of roasted vegetables or crab cakes.

And of course, optimal for French Fries and tater tots. Mustard aioli is also dynamite on corn dogs! I also like to use mine with brussels sprouts. It’s an all around great condiment for just about anything!

Storage and Freezing

​How to Store

You can store any leftover mustard aioli in an airtight container in the refrigerator for up to a week.

Can I Freeze Mustard Aioli?

I do not recommend freezing this creamy sauce as the ingredients will separate.
