How Long Do Mushrooms Last: Tips for Storing and Extending Their Shelf Life

Mushrooms are versatile and delicious ingredients known to elevate the flavor of various dishes. But their short shelf-life compared to other vegetables makes it crucial to learn how to store them properly. It's important to understand the lifecycle of mushrooms, whether bought in bulk or individually. By doing so, you can increase their longevity and reduce waste. This article explores the different factors that affect mushrooms shelf-life and provides valuable tips and tricks to help you keep them fresh for more extended periods. Discover proven ways to preserve and store mushrooms to ensure their quality and taste are maintained for longer.

Why Mushrooms Have a Short Shelf Life

Due to their high moisture content, mushrooms are vulnerable to bacteria and mold. Temperature and light fluctuations can quickly spoil them. Storing mushrooms correctly is crucial to extending their lifespan.

How Long Do Mushrooms Last?

Proper refrigeration is a vital step in extending the shelf-life of mushrooms. While most types can last for 7-10 days, certain varieties such as shiitake or oyster mushrooms need to be consumed sooner since they perish more quickly. Maintaining the freshness of mushrooms boils down to proper storage and consistent checks for signs of spoilage, including textural changes and color variation. It's a simple way of ensuring top-notch quality and flavor when cooked.

Factors That Affect The Shelf Life Of Mushrooms

There are a number of factors that affect the shelf life of mushrooms:

  1. Moisture content: Due to their high moisture content, mushrooms are vulnerable to the growth of mold and bacteria.
  2. Temperature: The proper storage of mushrooms is vital as they are very temperature sensitive. They require consistent refrigeration between 34-38°F (1-3°C) to avoid spoilage. Be sure to keep them at a constant temperature to maintain their quality.
  3. Light: Mushrooms are vulnerable to light, leading to rapid deterioration. To protect their quality and savor, it's important to store them in a dark place for extended shelf life.
  4. Airflow: Proper airflow is essential to prevent moisture and humidity buildup and promote freshness.
  5. Variety: Different mushroom varieties have varying lifespans, which makes it crucial to understand their specific storage requirements.
  6. Bruising: Mushrooms are fragile and can bruise easily, which can lead to spoilage and bacterial growth. Be gentle when handling them, and avoid stacking one on top of the other.
  7. Contamination: Keep mushrooms away from other foods that could contaminate them with bacteria or mold.
  8. Packaging: Store mushrooms in a paper bag or wrapped in paper towels to absorb excess moisture, and avoid storing them in plastic bags or containers.

Proper handling and storage of mushrooms are crucial as they are sensitive to various factors, including moisture, temperature, contamination, and packaging. Factors such as light, airflow, variety, and bruising also affect their quality. Therefore, it's best to handle them gently and store them in a consistent, dark, and well-ventilated place.

How Long Do Cooked Mushrooms Stay Good?

By keeping cooked mushrooms inside an airtight container in the refrigerator, they can survive up to 7 days. Before being stored in the fridge, ensure that the mushrooms have cooled down to room temperature.

To prevent food poisoning and ensure the safe consumption of your meals, disposing of mushrooms left unrefrigerated for over two hours is strongly advised. Keep this in mind next time you're handling mushrooms.

When reheating cooked mushrooms, make sure they are heated to an internal temperature of 165°F to ensure food safety.

How To Properly Prepare Mushrooms For Cooking

For an easy way to get mushrooms cooking-ready, follow these six simple steps:

Step 1: Choose fresh mushrooms

The first step to ensuring the longevity of your mushrooms is to select fresh ones. Look for mushrooms that are firm, plump, and free of blemishes. Avoid mushrooms that are slimy, discolored, or have a strong odor, as these are signs of spoilage.

Step 2: Clean the mushrooms

Before cooking with mushrooms, it's essential to clean them properly. Rinse them under cold running water and use a soft-bristled brush to remove any dirt or debris. Avoid soaking the mushrooms, as they can absorb excess water, which can lead to spoilage.

Step 3: Trim the stems

Trim the stems of the mushrooms using a sharp knife. Some recipes may call for removing the stems entirely, while others may require leaving them on. If you're unsure, follow the recipe's instructions.

Step 4: Slice or chop the mushrooms

Follow the recipe's instructions for either sliced or chopped mushrooms. Keep in mind that the size and shape of the mushrooms can affect their cooking time and texture.

Step 5: Cook the mushrooms

Now that your mushrooms are properly prepared, it's time to cook them. Saute, roast, grill, or use them in any recipe that calls for mushrooms.

Step 6: Store any leftover mushrooms properly

If you have any leftover mushrooms, store them in an airtight container in the fridge. They can last for up to five days if properly stored. Avoid reheating cooked mushrooms, as this can cause them to become soggy and lose their texture. Instead, use them as a topping for salads or sandwiches, or add them to a stir-fry or pasta dish.

Do Raw Mushrooms Last Longer Than Cooked Mushrooms?

No, raw mushrooms do not last longer than cooked mushrooms. In fact, cooked mushrooms have a shorter shelf life than raw ones. This is because cooking breaks down the cell walls and releases moisture, making them more susceptible to going bad. However, properly storing both raw and cooked mushrooms can help extend their shelf life and ensure they remain safe to eat.

How To Properly Store Mushrooms

To ensure your mushrooms remain fresh for longer, it's important to store them properly. Here are four simple steps to follow:

  1. Avoid plastic bags or containers

Mushrooms are quite sensitive and can quickly spoil when exposed to excess moisture. Avoid storing them in plastic bags or containers because these are prone to trap moisture, resulting in slimy fungi.

  1. Store in a dry, dark, and well-ventilated place

Mushrooms prefer cool, dark, and well-ventilated places. Store fresh, easily prepped mushrooms in an area that is cold, dry, and well-ventilated. Avoid exposure to direct sunlight for optimal results. Stash them in a paper or cloth bag, as it allows them to breathe and maintain their quality.

  1. Do not wash before storing

Mushrooms absorb moisture quickly, so it's best to avoid washing them before storage. It's best to avoid rinsing your belongings until you actually need them cleaned.

  1. Store in the fridge

To ensure freshness, refrigerate mushrooms if you don't plan to use them immediately. Place them in a paper or cloth bag and store them in the vegetable crisper. Avoid placing them near any moisture sources, such as fruits or vegetables that release moisture.

By following these guidelines, home cooks can enjoy fresh and safe mushrooms for a longer period of time.

Preservation Of Mushrooms

While fresh mushrooms have a short shelf life, there are various ways to preserve them for their nutritional and health benefits.


Fresh mushrooms can be dehydrated at a low temperature over a period of 24-48 hours. Dried mushrooms can be rehydrated for use in dishes in the future or ground into a powder to be used as a seasoning.

Dehydration is not a sufficient method to attain most of the nutritional and health virtues inherent in the mushrooms, and mushrooms that have just been dehydrated need further processing to become more bio-available.


You can preserve mushrooms in a vinegar brine or via lacto-fermentation to extend the shelf life into a shelf-stable good.


Health benefits can be concentrated out of the mushrooms in the form of a liquid tincture. Tinctures are extracted with water and alcohol or just water and then preserved with alcohol or glycerin. Tinctures are shelf stable for many years, and are a great way to access the health benefits latent in many mushrooms.

Powdered Extracts

Powdered extracts are made by boiling the mushrooms for a minimum of 2 hours, after a strong tea is made, the water is cooked off and the remaining mushrooms and concentrated tea are dehydrated and ground into a fine powder. This powder can be used for cooking or as a dietary supplement.


In conclusion, mushrooms can last for a decent amount of time if stored properly. Mushrooms can last up to a week when raw and up to five days when cooked. By avoiding excess moisture, storing them in a dry and dark place, refraining from washing them before storing, and refrigerating them, home cooks can extend the duration and freshness of their mushrooms. Remember to always follow this system to enjoy delicious and safe mushrooms for an extended period of time.
