Does Mayo Have Dairy?

You can add it to your favorite salad or sandwich. Mayonnaise makes almost every food taste so much better.

Almost as popular as ketchup, mayo is super creamy and helps to create some flavor even in bland foods.

Does Mayo Have Dairy

While many people know that mayo contains egg, not everyone knows that mayo doesn’t have any milk.

We find out whether your favorite condiment contains any dairy products, and what’s really in mayonnaise.

Does Mayo Contain Dairy?

No, most mayonnaise does not contain dairy and it is typically dairy-free. 

Products that have milk, cheese, butter or yogurt in them are not dairy-free. Luckily, mayo doesn’t contain any form of dairy, so people with lactose intolerance can safely eat mayonnaise.

Mayo is simply a combination of eggs, spices, vinegar or lemon juice. Due to the eggs, mayonnaise isn’t vegan but the traditional mayo recipe doesn’t include any dairy.

Saying this, there are some types of mayonnaise that add milk ingredients to create different flavors.

Eggless mayonnaise recipes often replace eggs with condensed milk. This makes the mayo a little sweeter and thicker than normal mayonnaise but it isn’t dairy-free anymore.

Also Portuguese mayonnaise is made with lemon juice, spices, oil as well as whole milk which means this type of mayo isn’t free from dairy.

Some mayonnaise manufacturers also add in Parmesan cheese and buttermilk to create a creamier texture.

If you see these ingredients on your favorite mayo’s label, then it’s not dairy-free.

Is Mayo OK For Lactose Intolerant?

As mayo doesn’t contain any lactose products such as milk, anyone with a lactose intolerance or a dairy allergy can safely enjoy mayo.

However, it’s important to keep in mind that some eggless mayo recipes use condensed milk as a replacement for eggs.

This means that eggless mayonnaise does usually contain dairy, and anyone allergic to lactose should avoid eggless mayo.

What’s In Mayonnaise?

If you are interested in making mayonnaise yourself or you just want to make sure that the mayo you buy doesn’t contain any dairy, then there are a few key mayo ingredients that you should look out for.

Traditionally, mayonnaise is made with four basic ingredients. These include oil, eggs, salt and some type of acid (usually vinegar or lemon juice).

Depending on your homemade mayonnaise recipe, you can also mix in some of your favorite mustard.

This will help blend the mixture and it increases the mayo flavor.

What Is Mayo?

Mayonnaise, or commonly known as mayo, is a condiment that can be added to salads and sandwiches.

Mayonnaise has a creamy, thick texture with a tart and tangy flavor.

The individual ingredients depend on the type of mayo but generally mayonnaise is a delicious mix of egg yolks, oil, flavorings, spices and acids, such as vinegar and lemon juice.

There are a wide range of different mayo varieties, including eggless, light and even specialty flavors.

How To Tell Your Mayo Is Dairy-free

If you ever picked up a mayonnaise from the shelf and wondered whether it is dairy-free, then there are a few sure ways to tell if your mayo contains dairy.

Read The Label

The best way to tell whether your mayo has dairy in it or not is by checking the ingredients list on the label.

Check if any of the ingredients contain dairy. Look out for things like condensed milk or cheese which have dairy.

If there are no dairy ingredients listed, then you can be sure that your mayo is dairy-free.

Make Your Own

Another great way to guarantee that your mayo does not have any dairy is to make your own mayonnaise.

Then you know exactly what you put in your mayo and you can specifically avoid any dairy products.

How To Use Mayo

Chances are that you have used mayo in a salad, sandwich or wth any of your favorite fries (Check out Are McDonald’s Fries Vegan?).

Mayo is such a versatile condiment, and although it isn’t as popular as ketchup (Find out Is Ketchup Vegan?), you can use it in plenty of different foods.

Mayo Salad Dressing

Thanks to its creamy texture, mayo works wonderfully as a salad dressing. You can squirt it on your potato or pasta (Find out Is Pasta Vegan?) salad, or use mayonnaise as a dressing base.

Potato Salad

Potato salad is very popular and there is almost no recipe where mayo doesn’t play an important role for adding flavor to bland potatoes.

You can add mayo on top of the salad or mix it in with some mustard and Parmesan cheese.

Mayonnaise-based Sauce

Mayonnaise on its own is a wonderful addition for every sandwich but if you want to spice things up, then make a herbal mayo with plenty of dill, rosemary and basil.

Plain mayo allows you to add almost any herb flavor.

Fish Stuffing

Perhaps not as commonly known as sandwich condiment, mayo can also be used to stuff fish.

Just mix some mayo with salt, lemon juice, pepper and a little brown sugar, and then stuff your favorite fish with it before cooking.

Is Mayo Gluten-free?

Yes, mayo is gluten-free. As mayonnaise only has a few basic ingredients, there is nothing in mayo that contains gluten.

Saying this, it is important to be aware of cross contamination. Your mayonnaise may be made in a factory where other gluten ingredients are handled.

This means that there is always a risk of contamination with mayonnaise, even though it is a relatively small risk.

If you can tolerate some gluten, then you should be fine to buy mayonnaise in store. However, if you prefer not to risk anything, then it’s a good idea to make mayo yourself at home.

Final Thoughts

Mayo is a great condiment that doesn’t contain any dairy, despite its bright white color.

Mayonnaise only includes spices, lemon juice (or vinegar) and egg yolks. These should be the basic ingredients.

However, you may also come across some other dairy mayo which contains milk and other dairy products.

If you are lactose intolerant, make sure that you check the ingredients list on the label for these products.
