How Long Do Cooked Mushrooms Stay Fresh in the Fridge?

Mushrooms are wonderful ingredients that can be used to create a range of dishes. They are versatile, healthy, and delicious. However, it’s important to know how to store them properly to ensure their freshness and taste.

If you’ve cooked too many mushrooms and you’re wondering how long they will stay good in the fridge, this guide will help you understand the storage methods and how long they last.

Cooked Mushrooms Storage Guide

The storage method is critical to preserving cooked mushrooms’ freshness and taste. Mushrooms are delicate and can spoil easily if not stored properly.


How long can cooked mushrooms stay fresh in the fridge?

Cooked mushrooms can remain fresh if stored correctly in the refrigerator. When stored in a container with an airtight lid, they can last between 3-5 days, depending on the type of mushrooms.

It’s important to let the cooked mushrooms come to room temperature before storing them in the fridge or freezing. Storing them while still hot can compromise their freshness and contribute to bacterial growth, resulting in premature spoilage.

The ideal temperature to store cooked mushrooms in the refrigerator is 40°F or lower. Once they exceed that temperature, their shelf life is significantly reduced.


How long do cooked mushrooms last in the freezer?

Cooked mushrooms can also be frozen to increase their shelf life. When correctly stored in an airtight container or a freezer-safe bag, they can last for up to 3-4 months.

It’s essential to freeze cooked mushrooms immediately after letting them cool down to preserve their freshness. Also, make sure to use them within the recommended period, because their quality can deteriorate if they stay in the freezer for too long.

It’s worth mentioning that freezing can alter the texture of mushrooms, so it may not be ideal for them to be frozen for dishes like salads or sandwiches. It’s best to use them for cooked dishes like soups and stews.

Factors That Affect Cooked Mushrooms Shelf Life

The shelf life of cooked mushrooms can be affected by several factors, including storage method, type of mushrooms, and hygiene.

Storage Method

The storage method is the most significant factor that can influence the shelf life of cooked mushrooms. Keeping them in the fridge or freezer, depending on the expected duration, is crucial to keep them fresh and maintain their taste.

Type of Mushrooms

The type of mushrooms can also affect their shelf life. More delicate mushrooms like shiitake and enoki may not last as long as thicker varieties like portobello.


Hygiene is an essential factor in ensuring the longevity of cooked mushrooms. Using clean utensils and dishware when preparing, serving, and storing cooked mushrooms is necessary to prevent bacterial contamination.

Signs Cooked Mushrooms Have Gone Bad

It’s essential to keep an eye on the cooked mushrooms’ condition to avoid consuming spoiled food. Some of the telltale signs of spoilt cooked mushrooms include:

  • Foul odor
  • Visible mold growth
  • Discoloration or slimy texture
  • Off taste

How to Store Cooked Mushrooms to Ensure Freshness

Cooked mushrooms can be stored using the following methods to ensure their freshness:

Airtight Containers

Airtight containers are ideal for storing cooked mushrooms in the refrigerator. Make sure to let them cool down to room temperature before storing them to avoid the accumulation of moisture, which can cause bacterial growth and spoilage.

Freezer-Safe Bags

Freezer-safe bags are ideal for storing cooked mushrooms in the freezer. Make sure to remove all the air from the bag before storing to prevent freezer burn and contamination.

Parchment Paper

Parchment paper is ideal for storing and wrapping cooked mushrooms. It’s less prone to stick to the mushrooms, which could result in a slimy texture. The paper’s moisture-absorbing properties can also help keep them fresh for longer.

The Bottom Line

When it comes to cooked mushrooms’ shelf life, proper storage and hygiene are the critical factors that determine their freshness and taste. Ensure that you store them in an airtight container or a freezer-safe bag and maintain appropriate temperature levels to prolong their shelf life.
