How long does miso soup last in the fridge

Miso soup can typically last in the fridge for up to 3 to 5 days. This timeframe allows you to enjoy the rich flavors without compromising safety. For the best experience, store it in an airtight container.

When refrigerating miso soup, ensure it cools down to room temperature first to maintain its quality. The ingredients in miso soup, especially if they include proteins like tofu or seaweed, can influence its shelf life.


Always check for signs of spoilage before consuming leftover miso soup. If it has an off smell, unusual taste, or noticeable growth, it’s best to discard it.

Factors that affect the shelf life of miso soup

Several factors can affect how long miso soup lasts, including the ingredients used, storage conditions, and your fridge temperature. Here’s what to consider:

  • Ingredients: Soups with fresh vegetables or proteins may spoil quicker than those with basic ingredients.
  • Storage: Use airtight containers to limit exposure to air, which can lead to quicker degradation.
  • Fridge temperature: Ensure your refrigerator is set at or below 40°F (4°C) to maximize food safety.
  • Cooked vs. uncooked: Miso soup that has been cooked and cooled properly lasts longer than versions left at room temperature before refrigeration.

How to store miso soup correctly

Proper storage can extend the life of your miso soup. Here are some tips:

  • Cool Before Storing: Allow soup to cool to room temperature before refrigerating.
  • Airtight Container: Store miso soup in a sealed container to keep out moisture and other odors.
  • Label and Date: It’s helpful to label your container with the date it was made, so you know when to consume it.

Freezing miso soup

If you want to keep miso soup for a longer period, consider freezing it. Here are the steps:

  • Separate Ingredients: For best results, freeze soup without added ingredients such as tofu or vegetables, as they may become mushy.
  • Use Freezer Bags: Store your miso soup in freezer bags or containers designed for freezing.
  • Label and Date: Don’t forget to label your bags with a date for future reference.

Miso soup can last up to 6 months in the freezer when stored properly.


Signs of spoiled miso soup

Always use your senses to judge the safety of your miso soup:

  • Odor: A sour or fermented smell indicates spoilage.
  • Texture: Slimy or fuzzy textures can be signs of mold growth.
  • Color Change: Significant discoloration may indicate that the soup has gone bad.
