French Mayonnaise Ingredients

You only need a few simple ingredients:

1 whole egg, at room temperature
1 teaspoon Dijon mustard
1 cup avocado oil
1/4 teaspoon salt
1/8 teaspoon black pepper
1 teaspoon vinegar or lemon juice (optional)

This straightforward list gives you plenty of room to adjust the flavors if desired. Whether you like your mayo tangy or smooth, you’re in control.

French Mayonnaise Recipe (Mason Jar Method)

Here’s how to make French mayonnaise with an immersion blender in a mason jar.

Add all ingredients to a wide-mouth mason jar.

Place your immersion blender into the jar, making sure it touches the bottom. Turn it on and blend without moving it for about 15 seconds. The mayonnaise will start to thicken and emulsify quickly.

After the bottom has thickened, slowly raise the immersion blender while continuing to blend. This ensures the oil fully incorporates and your mayonnaise becomes smooth and creamy.

And that’s it! Your mayonnaise is ready in no time.

Different Uses for French Mayonnaise

Homemade mayonnaise is incredibly versatile and adds depth of flavor. Here are some delicious ways to use it in your cooking:

Spread for Sandwiches and Burgers
Elevate your sandwiches or burgers by spreading a generous layer of homemade French mayo. Its tangy, creamy flavor enhances every bite.
Dip for French Fries and Vegetables
Use French mayonnaise as a dip for French fries, roasted veggies or even raw vegetables. It also pairs super well with salty snacks.
Base for Salad Dressings
Mix your mayonnaise with lemon juice, garlic, and fresh herbs for a quick, creamy salad dressing. It works wonderfully with green salads, potato salad, pasta salad or coleslaw.
Sauce for Seafood
French mayonnaise is a perfect base for seafood sauces. Add a little lemon and dill, and you’ve got a great topping for shrimp, crab or fish.
Deviled Eggs
Take your deviled eggs up a notch by using French mayonnaise. Its rich texture gives a smooth, rich filling.
Binding Agent for Meatballs or Patties
Mayonnaise can act as a binder for meatballs, crab cakes, or burger patties, helping to keep everything moist and flavorful.
Grilled Cheese Add-On
Instead of butter, spread a thin layer of mayonnaise on the outside of your bread before grilling. It gives your grilled cheese a perfectly crispy, golden crust.

Using French mayonnaise adds a gourmet touch to everyday dishes. Whether you’re making simple snacks or more elaborate meals, its versatility shines through.

Frequently Asked Questions

How do I store homemade French mayonnaise? Store your mayonnaise in the mason jar with a tight lid. Keep it refrigerated, and it will last up to five days.
Can I use olive oil or vegetable oil instead of avocado oil? Yes, but the type of oil will change the taste. Olive oil has a stronger flavor, which some might like. I prefer avocado oil for its mild taste and health benefits, but if swapping out oils, consider a taste-neutral oil like vegetable or canola.
What if my mayonnaise doesn’t thicken? This method should create thick mayonnaise quickly. If it doesn’t, try blending a bit longer, making sure the blender stays at the bottom before lifting.
Is there a way to fix separated mayonnaise? If your mayonnaise separates, add a teaspoon of water or mustard to the jar and blend again. This usually brings it back together.
What makes French mayonnaise different from regular mayonnaise? French mayonnaise typically has Dijon mustard and a slight tang from vinegar or lemon juice, giving it a more distinct flavor.
Why use an immersion blender instead of a whisk? Using an immersion blender speeds up the emulsifying process and gives a consistently smooth texture. However, you can certainly use a small bowl and whisk for this recipe; it just takes longer to prepare.
Why is my French mayonnaise yellow? French mayonnaise often appears yellow due to the use of fresh egg yolks and Dijon mustard, both of which give it a naturally golden color.

Making French mayonnaise in a mason jar with an immersion blender is quick, easy, and virtually mess-free. With just a handful of ingredients, you can create a gourmet condiment that elevates any meal. Whether you’re spreading it on a sandwich or using it as a dip, this recipe is sure to become a kitchen staple. Give it a try. Julia Child would be proud. : )
