How Long Do Mushrooms Last in the Fridge?

Are you a fan of mushrooms? Whether you enjoy them as a delicious addition to your meals or hate to waste food, knowing how long mushrooms can last in the fridge is essential. Understanding their lifespan can help you plan your meals, reduce food waste, and maximize your culinary adventures. In this article, we’ll explore the factors that affect the shelf life of mushrooms, how to make them last longer, freezing options, and signs of spoilage.

How Long Are Mushrooms Good For?

On average, mushrooms can stay fresh in the refrigerator for 5 to 7 days. However, several factors can influence their lifespan, including the type of mushroom, form, and storage method. Let’s dive into each of these factors:

Type of Mushroom

When it comes to shelf life, not all mushrooms are created equal. Portobello and cremini mushrooms last longer than white button mushrooms, which spoil more quickly. Consider the specific type of mushroom you have when determining how long it will stay fresh.

Form of Mushrooms

Whether you have whole mushrooms or sliced ones can also impact their shelf life. Whole mushrooms tend to last longer than sliced mushrooms. The increased surface area of sliced mushrooms exposes more mushroom flesh, making them more susceptible to spoilage.

Storage Method

The way you store mushrooms plays a crucial role in extending their lifespan. It is generally recommended to store mushrooms in a paper bag rather than a plastic bag. The paper bag allows for better air circulation, preventing moisture buildup and reducing the chances of early spoilage.

Tips for Extending Mushroom Freshness

To ensure your mushrooms stay fresh for as long as possible, follow these tips:

Importance of Storing Mushrooms in the Fridge

Mushrooms are highly perishable and sensitive to temperature changes. Storing them in the refrigerator helps slow the spoilage process and keeps them fresher for an extended period.

Extended Lifespan in the Fridge

By refrigerating your mushrooms, you can typically extend their lifespan to around 5 to 7 days. Remember to place them in a paper bag to maintain optimal freshness.

Impact of Slicing Mushrooms

As mentioned earlier, sliced mushrooms have a shorter lifespan than whole mushrooms. If you plan to use only some of the mushrooms at a time, it is wise to keep them whole until it is time to cook with them.

Keeping Mushrooms Raw

Whenever possible, try to keep your mushrooms raw until you’re ready to use them. Avoid pre-slicing or washing them in advance, as this can accelerate spoilage.

Using a Paper Bag for Storing Opened Mushrooms

If you’ve opened a package of mushrooms but only used a portion, transferring the remaining mushrooms to a paper bag can help prolong their freshness. The paper bag allows for better airflow, reducing moisture accumulation and extending lifespan.

Can You Freeze Mushrooms?

If you find yourself with excess mushrooms or want to preserve them for longer, freezing can be a viable option. However, keep in mind the following considerations:

Freezing as an Option for Preserving Mushrooms

Freezing mushrooms can help retain their flavor and texture for an extended period. It allows you to store them beyond their usual shelf life, providing a convenient option for future use.

Drawbacks of Freezing

Although freezing is a practical preservation method, it does have a few drawbacks:

1. Appearance: Mushrooms contain high water content, and freezing can affect their texture. Once thawed, mushrooms may appear less appealing due to increased water release.

2. Nutritional Value: Freezing can cause a slight loss of nutritional value in mushrooms. However, they still retain many beneficial nutrients, making frozen mushrooms a viable option for cooking.

Freezing Methods

If you decide to freeze your mushrooms, there are two primary methods:

1. Freezing Raw Mushrooms: Clean and slice the mushrooms, then spread them in a single layer on a baking sheet. Once frozen, transfer them to a freezer-safe container or bag. This method allows you to use the desired amount of frozen mushrooms without thawing the entire batch.

2. Cooking Mushrooms before Freezing: Cook the mushrooms in a preferred manner, such as sautéing, blanching, or roasting. Allow them to cool and store them in a freezer-safe container or bag. This method preserves the cooked mushrooms for future use.

How Long Does Frozen Mushroom Last?

Frozen mushrooms can typically maintain quality for about 9 to 12 months when stored properly in the freezer. Ensure they are tightly sealed to prevent freezer burn.

When you’re ready to use frozen mushrooms, allowing them to thaw completely before incorporating them into your recipes is crucial. This ensures even cooking and maintains the desired texture.

Identifying Signs of Spoiled Mushrooms

Knowing how to identify spoiled mushrooms is essential for maintaining food safety. Look out for the following signs:

Signs of a Bad Mushroom:

  1. Slimy Texture: If your mushrooms feel slimy or sticky to the touch, they have likely spoiled and should be discarded.
  2.  Shrinking or Wrinkling: Mushrooms that have begun to shrink or develop wrinkles are no longer fresh and should not be consumed.
  3.  Darkening or Developing Dark Spots: Any significant darkening or the presence of dark spots on the mushrooms is an indication of spoilage.
  4.  Unusual Odor: Spoiled mushrooms often emit a strong, unpleasant odor. It’s best to avoid consuming them if they have a foul smell.


Understanding the lifespan of mushrooms and how to store them properly can help you reduce food waste and make the most of this versatile ingredient. On average, mushrooms can last in the fridge for 5 to 7 days, but factors such as mushroom type, form, and storage method can influence their lifespan.

Consider these factors when planning your meals and deciding how to store your mushrooms. Freezing can be a practical option for preserving mushrooms, but be aware of the slight changes in appearance and potential loss of nutritional value.

By being mindful of signs of spoilage and following proper storage practices, you can enjoy fresh mushrooms for an extended period and create delicious dishes with confidence.
