Mayonnaise, commonly known as mayo, is a popular condiment used in various dishes and sandwiches. It is a creamy and tangy sauce that adds flavor and richness to food. However, for those following a vegetarian diet, the question arises: is mayo vegetarian? Let’s delve into this topic and explore the ingredients and production process of mayo to determine its vegetarian status.

Understanding Mayo Ingredients

Mayonnaise is traditionally made from a combination of oil, egg yolks, vinegar or lemon juice, and seasonings. These ingredients are emulsified to create a smooth and creamy texture. However, the specific ingredients used in mayo can vary depending on the brand and recipe. To determine if mayo is vegetarian, we need to examine the key components:


Eggs are a primary ingredient in traditional mayo recipes. They provide the emulsifying properties necessary to create the creamy texture. However, eggs are derived from animals, making them unsuitable for a vegetarian diet. Vegetarians who consume eggs may consider mayo made with eggs as vegetarian-friendly.

Egg Replacers

Some manufacturers produce vegetarian-friendly mayo by using egg replacers. These substitutes mimic the emulsifying properties of eggs without using animal-derived ingredients. Common egg replacers in vegetarian mayo include soy protein, pea protein, or other plant-based ingredients. Vegetarians can opt for mayo made with these egg replacers to ensure it aligns with their dietary choices.

Vegetarian Mayo Brands

As the demand for vegetarian and vegan products increases, many brands have started offering mayo alternatives suitable for those following a plant-based diet. These vegetarian mayo options are made without eggs or animal-derived ingredients. Here are a few popular vegetarian mayo brands:

  • Vegenaise: Vegenaise is a well-known brand that produces vegan mayo made from non-GMO soybeans. It is free from eggs, dairy, and other animal products.
  • Just Mayo: Just Mayo is another popular vegan mayo brand that uses a combination of pea protein and other plant-based ingredients to create a creamy texture.
  • Hellmann’s Vegan: Hellmann’s, a renowned mayo brand, offers a vegan version made with plant-based oils and starches instead of eggs.

Labeling and Certification

When purchasing mayo, it is essential to read the labels carefully. Look for indications such as “vegan,” “vegetarian,” or “egg-free” to ensure the product aligns with your dietary preferences. Additionally, some products may carry certifications from recognized organizations, such as the Vegan Society or Vegetarian Society, which provide further assurance of their vegetarian status.

Homemade Vegetarian Mayo

For those who prefer to make their own mayo at home, there are numerous vegetarian-friendly recipes available. These recipes often use egg substitutes like aquafaba (the liquid from canned chickpeas) or silken tofu to achieve the desired texture. By making mayo from scratch, vegetarians can have complete control over the ingredients and customize the flavors to their liking.


Mayo can be both vegetarian and non-vegetarian, depending on the ingredients used in its production. Traditional mayo recipes contain eggs, making them unsuitable for vegetarians. However, many brands now offer vegetarian and vegan mayo alternatives made without eggs or animal-derived ingredients. By carefully reading labels and choosing certified products, vegetarians can enjoy mayo that aligns with their dietary choices. Additionally, homemade mayo recipes provide an opportunity to create vegetarian-friendly versions using egg substitutes. Ultimately, the choice of whether mayo is vegetarian or not lies in the hands of the consumer.
