How Long Do Mushrooms Last In The Fridge?

Have you ever bought a pack of mushrooms to use in a recipe, only to forget about them and find them shriveled up and unusable in your fridge?

Or maybe you have thrown out perfectly good mushrooms because you weren’t sure how long they would last. 

As with most fresh produce, mushrooms have a limited shelf life, proper storage plays a crucial role in extending the shelf life of mushrooms. 

In this blog post, we will dive into the world of mushroom storage and answer that burning question- how long do mushrooms last in the fridge?

Get ready to say goodbye to wasted food and hello to fresh ingredients every time! 

The Quality Of Mushrooms When Stored In The Fridge

Mushrooms have become a staple ingredient in cuisines worldwide due to their unique flavor and versatility.

They can easily absorb the flavors of other ingredients, making them a favored choice for dishes ranging from simple sautés to complex stews. 

Additionally, mushrooms are celebrated for their nutritional benefits.

They are a low-calorie food source rich in vital nutrients like Vitamin D, selenium, phosphorus, and potassium, not to mention their high protein and fiber content compared to most vegetables. 

This nutritional profile makes mushrooms a nutritious addition to any diet, appealing especially to those looking for plant-based protein sources.

Mushrooms are delicate and have a high moisture content, making them prone to spoilage.

When stored in the fridge, mushrooms can last longer depending on their freshness when purchased and how they are stored. 

Whole, raw mushrooms will keep longer than sliced or chopped ones due to the exposed surface area being smaller.

If you plan on using your mushrooms within a few days, you can leave them in their original packaging. 

However, for longer storage times, it is best to transfer them to an airtight container or wrap them tightly in plastic wrap before refrigerating.

This will help prevent the mushrooms from drying out and developing a slimy texture. 

How Long Do Mushrooms Last In The Fridge?

The storage time of mushrooms depends on many different factors, such as the type of mushrooms, how fresh they are when purchased, and whether they are stored properly.

Here’s a breakdown of how long different types of mushrooms can last in the fridge:

1. Raw Mushrooms

Generally, raw mushrooms can last in the fridge for about 4 to 7 days when stored correctly.

This timeframe can vary slightly depending on the mushroom type.

For instance, button and cremini mushrooms tend to stay fresh closer to the 7-day mark, whereas softer, more delicate varieties like oyster mushrooms may start to decline around the 3 to 4-day point.

2. Diced Mushrooms

If you have diced or sliced mushrooms, they may not last as long as whole mushrooms.

Diced mushrooms should be used within 1 to 2 days for optimal freshness. 

Chopped or sliced mushrooms have a larger surface area, which means they are more prone to moisture loss and spoilage.

For this reason, it’s best to only chop or slice the mushrooms right before using them.

3. Cooked Mushrooms

Cooked mushrooms will generally last for 3 to 5 days in the fridge.

However, this timeframe can vary based on factors such as how they were cooked and what other ingredients are included in the dish.

For example, if you cook mushrooms in a sauce or with other vegetables, their shelf life may be reduced due to added moisture and potential bacterial growth.

Similarly, if you use mushrooms in a dish that includes meat, they will likely have a shorter shelf life due to the meat’s perishable nature.

4. Dried Mushrooms

Dried mushrooms are an excellent option for extending the shelf life of mushrooms.

They can last several months or even up to a year when stored properly in an airtight container in a cool, dry place.

Although storing dried mushrooms in a refrigerator is not necessary, doing so can help preserve their quality over an extended period, especially in humid climates.

Additionally, refrigeration can protect dried mushrooms from pests and temperature fluctuations that could impact their flavor and texture over time.

For each type of mushroom and different conditions, the time mushrooms last in the fridge is different.

However, it is essential to use your mushrooms as soon as possible for the best flavor and nutritional value.

How To Store Mushrooms In The Fridge?

Now that you know the different types of mushrooms and how long do mushrooms last in the fridge, here are 5 simple steps to storing them correctly for optimal freshness:

1. Store In a Paper Bag Or a Loosely-Closed Container

Mushrooms need air circulation to stay fresh, so avoid storing them in an airtight container.

A paper bag or a loosely-closed container allows for proper air circulation while protecting the mushrooms from absorbing moisture or odors from other foods.

2. Keep Them Dry

Moisture is the enemy of mushrooms, so avoid washing them until you’re ready to use them.

If your mushrooms are dirty, wipe them with a damp cloth or paper towel instead of rinsing them under running water.

3. Avoid Exposure To Direct Sunlight

Like many vegetables, mushrooms are sensitive to light and can spoil faster when exposed to direct sunlight.

Store them in a dark, cool place in your fridge.

4. Check On Them Periodically

Mushrooms can start to decline quickly after the 3-4 day mark, so it’s essential to check on them regularly for any signs of spoilage.

5. Use Them Promptly

To get the most out of your mushrooms, use them as soon as possible after purchasing or harvesting them.

The longer they sit in the fridge, the more likely they are to lose their freshness and flavor.

By following these storage tips and paying attention to the different types of mushrooms and their various lifespans, you can enjoy tasty and nutritious mushrooms for longer periods.

Should Mushrooms Freeze?

You may be wondering if it’s possible to freeze mushrooms to extend their shelf life.

The answer is yes, but there are some important considerations to keep in mind.

First and foremost, mushrooms should be cooked before freezing.

Freezing raw mushrooms will cause them to become mushy and lose flavor when thawed.

To prepare mushrooms for freezing, cook them in a bit of oil or butter until they become tender, then let them cool completely.

You can also add some herbs and spices for added flavor.

Once cooled, pack the cooked mushrooms into an airtight container or freezer bag and label with the date.

Frozen mushrooms can last up to 9 months if stored properly in the freezer.

When ready to use, simply thaw the mushrooms in the fridge and add them to your favorite dishes.

Some Factors That Affect Mushrooms Last In The Fridge

As soon as you know how long do mushrooms last in the fridge, here are several factors that can impact how long mushrooms last in the fridge.

These include:

1. Freshness when purchased: The fresher the mushrooms are when you buy them, the longer they will last in your fridge.

2. Storage temperature and humidity: Mushrooms should be stored at a cool temperature (around 36 to 41°F) and moderate humidity (85 to 95%) to maintain their freshness.

3. Properly storing and handling: Following the storage tips mentioned earlier is crucial in keeping your mushrooms fresh for longer periods.

4. Variety of mushrooms: Different types of mushrooms have varying lifespans, so it’s essential to know the specific variety you’re working with and its ideal storage conditions.

5. Cooking method and ingredients: How you cook mushrooms and what other ingredients are used in the dish can affect their shelf life.

By considering these factors and being mindful of proper storage techniques, you can enjoy fresh and delicious mushrooms for longer periods.

How Do Mushrooms Say They Have Gone Bad?

Besides, mushrooms can spoil quickly, so it’s crucial to know how to identify when they’ve gone bad.

Here are some signs that your mushrooms have spoiled and should not be consumed:

1. Slimy texture: If your mushrooms feel slimy or sticky to the touch, this is a clear sign of spoilage. This sliminess indicates bacterial growth and can also cause an off-putting smell.

2. Discoloration: If your mushrooms have turned dark or developed spots of discoloration, this could indicate mold growth and spoilage.

3. Strong odor: Mushrooms should have a mild earthy aroma. If they start to smell funky or pungent, this is a sign of spoilage.

If you notice any of these signs, it’s best to discard your mushrooms and avoid consuming them.

Conclusion

To conclude, mushrooms can be a delicious and nutritious addition to any dish, but they do require proper storage techniques to maintain their freshness.

By knowing the answer to the main question of how long do mushrooms last in the fridge and proper storage methods, you can enjoy tasty mushrooms for longer periods.

Remember to always use your mushrooms as soon as possible for the best flavor and nutritional value, and discard them if you notice any signs of spoilage.

With these tips in mind, you can make the most out of your mushrooms and elevate your meals with their unique flavors and textures.
