Let’s start with the basics: homemade mayonnaise is made from egg yolks, oil, vinegar or lemon juice, and seasonings.

That way, you can enjoy your homemade mayo without worrying about its freshness. So, let’s dive in and learn how to keep your homemade mayo fresh for as long as possible!

How to make homemade mayonnaise

Making homemade mayonnaise is surprisingly easy and requires just a few simple ingredients:

  • 1 egg yolk
  • 1/2 teaspoon salt
  • 1 teaspoon Dijon mustard
  • 1 tablespoon lemon juice
  • 1/2 cup vegetable oil

Follow these steps to make your own delicious mayo:

  1. In a small mixing bowl, whisk together the egg yolk, salt, Dijon mustard, and lemon juice until well combined.
  2. While continually whisking, slowly pour in the oil, drop by drop, until the mixture starts to thicken.
  3. Once the mixture starts to thicken, you can start to pour the oil in a thin stream. Continue whisking until all the oil has been incorporated.
  4. Refrigerate your homemade mayo in an airtight container until ready to use.

You can experiment with different oils, vinegars, and herbs to create different flavors of mayo. If you prefer a lighter mayo, you can also add a small amount of Greek yogurt or sour cream.

The Ingredients Needed to Make Homemade Mayonnaise

Making homemade mayonnaise requires only a few ingredients that are readily available in most households. Unlike commercial mayonnaise, homemade mayonnaise does not contain any preservatives which means it has a shorter lifespan. But with proper storage, it can last for up to a week to a week and a half in the fridge.

  • Egg yolks – The yolks act as an emulsifier that helps to bind the oil and vinegar together.
  • Oil – Neutral oils such as vegetable, canola, or grapeseed oil work best for making mayonnaise. These oils have a mild flavor that does not interfere with the flavor of the mayonnaise.
  • Vinegar or Lemon Juice – The acidic component helps to balance the flavor and also acts as a preservative. You can use white vinegar, apple cider vinegar, or freshly squeezed lemon juice, depending on your preference.
  • Mustard – Adds flavor and helps to stabilize the emulsion. You can use dijon, yellow, or brown mustard.
  • Salt – Enhances the flavor of the mayonnaise.

Why Homemade Mayonnaise Has a Shorter Lifespan

Homemade mayonnaise has a shorter lifespan compared to commercial mayonnaise because it does not contain any stabilizers or preservatives. This means that it is more susceptible to bacterial growth, especially if stored improperly.

To prolong the lifespan of homemade mayonnaise, it is essential to store it in an airtight container in the refrigerator. It is also important to use clean utensils and containers when handling and storing the mayonnaise to prevent contamination.

How Long Does Homemade Mayonnaise Last in the Fridge?

The lifespan of homemade mayonnaise in the fridge depends on the freshness of the ingredients used and how well it is stored. Homemade mayonnaise can last for up to a week to a week and a half in the fridge if stored properly.

It’s best to make homemade mayonnaise in small batches to avoid waste and ensure freshness. If you notice any changes in color, texture, or smell, discard the mayonnaise immediately as it may have gone bad.

The Benefits of Making Homemade Mayonnaise

Making homemade mayonnaise is not only delicious but also has several benefits to offer. Here are some of the advantages of making your own mayonnaise:

  • Healthier Option: Store-bought mayonnaise often contains preservatives, additives, and excess sugar that can harm your health. Homemade mayonnaise, on the other hand, is made with fresh ingredients, making it a healthier option.
  • Customization: When you make your mayonnaise, you have the option to customize it as per your liking. You can experiment with different types of oils, flavors, and textures to create a unique and delicious mayonnaise that suits your taste.
  • Longer Shelf Life: One of the most significant benefits of making homemade mayonnaise is that it lasts longer than store-bought mayonnaise. Homemade mayonnaise can last up to two weeks in the fridge, whereas store-bought mayonnaise often contains preservatives and has a short shelf life.

  • Store it in an airtight container: Transfer your homemade mayonnaise to an airtight container to prevent moisture and bacteria from getting in. This will help your mayonnaise last longer and retain its flavor.
  • Refrigerate it at all times: Homemade mayonnaise should always be refrigerated to prevent bacteria from growing. Leave it out at room temperature for too long and it can quickly spoil and become unsafe to consume.

The Disadvantages of Making Homemade Mayonnaise

While homemade mayonnaise can be a delicious and cost-effective alternative to store-bought varieties, there are a few notable drawbacks that should be considered before diving in. Here are some of the disadvantages of making homemade mayonnaise.

  • Shorter Shelf Life: Unlike store-bought mayonnaise, homemade mayonnaise usually has a much shorter shelf life, typically lasting only a few days to a week in the fridge. This is because homemade mayonnaise is made with raw egg yolks that can spoil quickly if not properly stored and handled.
  • Time-Consuming: Making mayonnaise from scratch can be a time-consuming process, especially if you’re new to it. It requires a careful balance of ingredients and a lot of elbow grease to emulsify the mixture properly.
  • Potential Safety Concerns: Since homemade mayonnaise is made with raw eggs, there is a risk of contracting a foodborne illness like salmonella. However, this risk can be mitigated by using pasteurized eggs or by making the mayonnaise with a cooked egg yolk.

The Risk of Foodborne Illness

One of the biggest concerns when it comes to homemade mayonnaise is the risk of contracting a foodborne illness. Since homemade mayonnaise is made with raw egg yolks, there is a chance that it could be contaminated with harmful bacteria like salmonella.

To reduce the risk of foodborne illness, it’s important to use fresh, high-quality eggs and to store the mayonnaise properly. Homemade mayonnaise should be kept refrigerated at all times, and any leftover mayonnaise should be discarded after a few days.

Storing Homemade Mayonnaise

Proper storage is key when it comes to homemade mayonnaise. To keep the mayonnaise fresh as long as possible, it should be stored in a clean, airtight container in the refrigerator.

If the mayonnaise has been left at room temperature for more than two hours, it should be discarded immediately. It’s also a good idea to mark the container with the date the mayonnaise was made so you can keep track of how long it’s been in the refrigerator.

How Long Store-Bought Mayonnaise Lasts in the Fridge

Mayonnaise is a common condiment used in many households. It’s delicious on sandwiches, salads, and as a dipping sauce. The shelf life of store-bought mayonnaise depends on many factors such as the brand, ingredients, and storage conditions.

  • Unopened store-bought mayonnaise can last up to 3 months in the fridge.
  • Once opened, the shelf life reduces to 1-2 months.
  • Homemade mayonnaise or mayonnaise made from scratch has a shorter shelf life than store-bought ones because of the lack of preservatives. Homemade mayonnaise can last up to 1 week in the fridge.

It’s important to store mayonnaise properly to extend its shelf life. Store-bought mayonnaise should be stored in the refrigerator at all times and away from direct sunlight and heat.

Store-bought mayonnaise also comes in different varieties, such as low-fat or reduced-fat mayonnaise. These types have a shorter shelf life due to the added water content and lack of preservatives. It’s essential to check the expiration date before using any store-bought mayonnaise, including reduced-fat or low-fat ones.

To ensure the safety and quality of your mayonnaise, check for any signs of spoilage, such as a change in color, texture, or smell. Discard any mayonnaise that has a sour or foul odor, a strange color, or unusual texture. Additionally, always use a clean utensil to scoop mayonnaise to prevent bacteria growth.

In summary, store-bought mayonnaise has a shelf life of 3 months when unopened and 1-2 months when opened. Reduced-fat or low-fat mayonnaise has a shorter shelf life, and homemade mayonnaise has a shelf life of 1 week. Proper storage and handling are essential to maximize the shelf life of mayonnaise and ensure its safety and quality.

Tips for Storing Homemade Mayonnaise

Homemade mayonnaise is a delicious and versatile condiment that you can whip up easily at home. But how long does it last in the fridge? And what are the best tips for storing it to keep it fresh and safe? Here are some expert tips to help you store your homemade mayonnaise:

  • Always use clean utensils and containers when making and storing your homemade mayonnaise. Any bacteria or contaminants can spoil the delicate emulsion and reduce its shelf life.
  • Store your mayonnaise in an airtight container with a tight-fitting lid. This will prevent air and moisture from getting in and causing spoilage. Glass jars or plastic containers are good options, but avoid metal containers as they can react with the acidic ingredients in the mayo.
  • Keep your mayonnaise in the coldest part of your fridge, such as the back or bottom shelf. This will help it stay fresh for longer and reduce the risk of bacterial growth.
  • Label your container with the date you made the mayonnaise so that you can keep track of its freshness. Homemade mayonnaise can last for up to a week in the fridge, but it’s best to consume it within 3-4 days to ensure maximum freshness and quality.
  • Avoid leaving your mayonnaise out at room temperature for more than 2 hours. This can increase the risk of bacterial growth and spoilage. If you need to serve your mayo at room temperature, take it out of the fridge just before serving and return it promptly when you’re done.
  • If you notice any strange smells, colors, or textures in your mayonnaise, discard it immediately. These are signs of spoilage and can make you sick if consumed.

By following these tips, you can ensure that your homemade mayonnaise stays fresh, safe, and delicious for as long as possible. Enjoy!

  • The mayonnaise smells rancid or sour. If the mayonnaise smells off or has an unpleasant odor, it is an indication that it has gone bad.
  • The texture of the mayonnaise has changed. If the mayonnaise appears to be separated or lumpy, it is not safe for consumption.

It is important to store homemade mayonnaise properly to prevent it from spoiling. The mayonnaise should always be stored in an airtight container in the refrigerator. It is recommended to consume homemade mayonnaise within three to four days to ensure its freshness and safety.

There’s no denying that homemade mayonnaise is a delicious addition to any sandwich or salad. But if left out too long or not stored properly, it can quickly go bad. Here are some tips to keep your homemade mayonnaise fresh and safe to eat:

  • Use pasteurized eggs – Pasteurized eggs are heated to kill any bacteria that may be present, reducing the risk of foodborne illness.
