Fail-Proof Homemade Mayonnaise

Making your own mayonnaise at home can be daunting, but with the right recipe and technique, it can become a fail-proof process. Store-bought mayonnaise often contains additives and preservatives, while homemade mayo allows you to have full control over the ingredients, ensuring a healthier and tastier option for you and your loved ones.

To create a fail-proof homemade mayonnaise, you will need a few simple ingredients:

  • Eggs: Fresh eggs will give your mayo a rich and creamy texture.
  • Oil: Choose a neutral-tasting oil like vegetable or grapeseed, which will not overpower the flavor of the mayonnaise.
  • Vinegar or Lemon Juice: Acid is crucial to give your mayo a tangy flavor. You can use either white vinegar or fresh lemon juice.
  • Mustard: A small amount of mustard will help emulsify the ingredients and give the mayo a smoother texture.
  • Salt: Add salt to taste, enhancing the overall flavor.

To start, separate the egg yolks from the whites and place them in a medium-sized bowl. Whisk the yolks until they become smooth and slightly thickened. Gradually add the oil, a few drops at a time, whisking vigorously until the mixture begins to thicken. Once the mayonnaise starts to emulsify, you can add the oil in a slow, steady stream, continuing to whisk until it reaches the desired consistency. Finally, add vinegar or lemon juice, mustard, and salt, and whisk until everything is well combined.

With a little practice and careful attention to detail, you can easily whip up a fail-proof homemade mayonnaise that is both delicious and preservative-free. Enjoy it as a dip, spread, or as a base for your favorite sauces and dressings!




Eggs are the base ingredient for homemade mayonnaise. They provide emulsifying properties that help to bind the oil and other ingredients together. It’s important to use fresh and high-quality eggs for the best results.


Oil is the main component of mayonnaise and provides its creamy texture. It’s important to use a neutral-flavored oil, such as canola or vegetable oil, as it won’t overpower the flavor of the other ingredients. Olive oil can also be used for a more robust flavor.



An acid, such as lemon juice or vinegar, is necessary to give homemade mayonnaise its tangy taste. The acid also helps to stabilize the emulsion and prevent separation. Freshly squeezed lemon juice or white vinegar are popular choices for homemade mayonnaise.



Mustard acts as an emulsifier and helps to bind the oil and other ingredients together. It also adds a subtle tanginess to the mayonnaise. Dijon or yellow mustard can be used, depending on your preference.


Seasonings, such as salt and pepper, can be added to enhance the flavor of the mayonnaise. You can also experiment with additional herbs and spices, such as garlic powder, paprika, or cayenne pepper, to customize the taste.

  • Eggs: Fresh and high-quality eggs
  • Oil: Neutral-flavored oil like canola or vegetable oil
  • Acid: Lemon juice or vinegar
  • Mustard: Dijon or yellow mustard
  • Seasonings: Salt, pepper, and optional herbs/spices

With these ingredients on hand, you’ll be well-equipped to make a fail-proof homemade mayonnaise that’s both delicious and versatile.

Step-by-Step Instructions

  1. Gather your ingredients: You will need 1 egg yolk, 1 teaspoon of Dijon mustard, 1 tablespoon of lemon juice, 1 cup of vegetable oil, and salt and pepper to taste.
  2. Whisk the egg yolk and mustard: In a medium bowl, whisk together the egg yolk and Dijon mustard until well combined. This will help to emulsify the mayonnaise.
  3. Add the lemon juice: Slowly add the lemon juice to the egg yolk mixture while continuing to whisk. The lemon juice adds brightness and helps to stabilize the mayonnaise.
  4. Slowly stream in the oil: Begin adding the vegetable oil to the egg yolk mixture very slowly, while whisking continuously. It is important to add the oil in a slow, steady stream to ensure that the mayonnaise emulsifies properly and doesn’t separate.
  5. Continue whisking until thickened: As you add the oil, the mayonnaise will begin to thicken. Keep whisking until it reaches your desired consistency. If the mayonnaise becomes too thick, you can add a small amount of water to thin it out.
  6. Season with salt and pepper: Once the mayonnaise has reached the desired consistency, season it with salt and pepper to taste. Adjust the seasoning as needed.
  7. Transfer to a jar: Transfer the homemade mayonnaise to a clean jar or container and refrigerate for at least 30 minutes before using. The mayonnaise will continue to thicken as it chills.

Now that you have mastered this fail-proof homemade mayonnaise recipe, you can enjoy the creamy goodness on sandwiches, salads, and more!
