How long does mayonnaise last in the fridge

Mayonnaise generally lasts about 2 months in the fridge if unopened and 3-4 months after being opened. However, this duration can vary based on the mayonnaise’s ingredients and storage conditions. To ensure your mayonnaise stays fresh:

  • Store it in the fridge at all times after opening.
  • Tightly seal the jar to prevent contaminants.
  • Always check for discoloration or an off smell before use.

It’s essential to understand how long mayonnaise lasts in the fridge, especially if it’s homemade or if the jar has been opened for a while.
