Mushrooms are a versatile ingredient that can be used in a variety of dishes, from pasta to meat roasts. However, their high water content and spongy texture make them prone to spoilage, especially when stored in the refrigerator. When properly stored, raw mushrooms can last for about a week in the fridge, while cooked mushrooms should be consumed within 3 to 4 days. To extend their lifespan, various storage methods can be employed, such as using paper bags, marinating, or freezing, each with its own advantages and drawbacks.

What You'll Learn
Raw mushrooms last 3-7 days in the fridge
Mushrooms have a high water content, making them extremely porous. This means they have a shorter shelf life than other vegetables like cabbage, carrots, or sweet potatoes. To maximize their lifespan, it is recommended to store mushrooms with the stems intact to minimize their exposure to air. They should also be kept unwashed in a porous container with paper towels to absorb excess moisture, as fungi thrive in damp, sealed environments.
It is important to inspect mushrooms for signs of spoilage before consuming them. Mushrooms that have gone bad will develop dark spots, feel or look slimy or mushy, or emit a pungent odour. To prevent spoilage, some sources suggest freezing mushrooms, either raw or cooked. However, freezing can affect their texture, causing them to become limp and mushy when thawed. If you choose to freeze mushrooms, it is recommended to cook or blanch them beforehand to help retain their structure and flavour.
By understanding the factors that influence the shelf life of raw mushrooms and following proper storage practices, you can ensure that your mushrooms stay fresh and edible for the full 3-7 day period in the fridge.

Cooked mushrooms last 3-4 days in the fridge
Cooked mushrooms will typically last in the fridge for 3–4 days. This is a shorter shelf life than raw mushrooms, which can be kept in the fridge for 5–7 days. However, it is important to note that mushrooms are highly perishable, and they can quickly become slimy or develop dark spots and mould if not stored properly.
To maximise the lifespan of cooked mushrooms, it is best to store them in an airtight container in the refrigerator. This will help to keep them fresh for as long as possible. It is also important to note that mushrooms are highly porous and have a high water content, which makes them great for cooking but also means they can spoil quickly.
To prevent spoilage, it is recommended to store mushrooms in a porous container that promotes air circulation. Paper towels can also be used to absorb excess moisture, as fungi often thrive in damp, sealed environments. Additionally, it is best to store mushrooms in their original container or a paper bag rather than a plastic bag, as plastic can trap moisture and cause the mushrooms to spoil more quickly.
If you want to keep mushrooms for longer than a few days, freezing is an option. However, freezing mushrooms can affect their texture and make them mushy when thawed due to their high water content. To maintain their structure, it is recommended to cook, blanch, sauté, poach, or steam mushrooms before freezing.

Frozen mushrooms last 9-12 months
Fresh mushrooms can be stored in the refrigerator for about a week before they start to spoil. They can also be frozen to prolong their shelf life, but this can negatively affect their quality. Mushrooms have a high water content, and freezing causes water molecules to expand and sometimes burst, damaging the mushroom's cell walls. As a result, when frozen mushrooms are thawed, they may become limp and mushy.
However, if you're looking to make the most of your mushrooms and reduce food waste, freezing them is a great option. Frozen mushrooms will last in your freezer for 9-12 months. To prepare them for freezing, it is recommended that you cook them first to ensure optimal quality. You can steam, saute, or blanch them before freezing. Blanching, in particular, helps to preserve produce by destroying enzymes that can cause spoilage. It also inactivates Listeria and Salmonella, improving food safety.
When it comes to cooking with frozen mushrooms, they are best suited for dishes that will be thoroughly cooked, such as soups, casseroles, stews, or as a pizza topping. You can also add them to dishes like pasta, rice, or quinoa by allowing them to thaw in the refrigerator until they are softened enough to use.
It's important to note that freezing mushrooms may alter their texture, but they can still be delicious in various recipes. Some people choose to freeze mushrooms raw, and while this is possible, cooking them first will help preserve their quality. Additionally, while freezing does not affect the calorie, fiber, or mineral content of mushrooms, it can reduce their nutritional value over time.

Vacuum sealing raw mushrooms can make them last 3 weeks
Fresh mushrooms have a short shelf life, typically lasting only a few days in optimal conditions. In general, raw mushrooms can last for anywhere between three and seven days in the fridge. However, vacuum sealing them can extend their shelf life by up to three weeks.
Vacuum sealing is a popular method for preserving food by reducing its exposure to oxygen, which slows down the deterioration process. While it helps inhibit bacterial growth, it does not eliminate the need for proper food safety practices. When vacuum sealing leftovers, they will generally last twice as long as they would have without the vacuum seal. For example, pizza will last about a week when vacuum-sealed versus three days without.
Mushrooms have a high water content and are extremely porous, making them great for cooking and eating but challenging to store. Their water content and absorbency can lead to spoilage, resulting in a soggy, slimy mess. Therefore, it is essential to store them correctly to prevent this from happening.
The best method for storing mushrooms will keep them free of slime and mold and even improve their taste. One effective way to store mushrooms is to place them in a paper bag in the refrigerator. The paper bag absorbs excess moisture and maintains freshness. However, this method may not keep the mushrooms fresh for more than ten days, as some users have reported minor slime development by then.
Vacuum sealing raw mushrooms can be an even more effective way to extend their shelf life by up to three weeks. However, it is important to note that some sources advise against vacuum sealing raw mushrooms. Instead, it is recommended to vacuum seal dried mushrooms or cooked dishes containing mushrooms.

Marinated mushrooms last 10-14 days in the fridge
Fresh mushrooms are a versatile ingredient that can be used in a variety of dishes. However, their high water content and porous nature make them prone to spoilage, resulting in a slimy, soggy mess if not stored properly.
Marinated mushrooms can last in the fridge for 10-14 days. This extended shelf life is due to the marinade, which can include ingredients like oil, vinegar, and herbs that inhibit bacterial growth. However, it's important to note that the specific ingredients and preparation methods can affect this timeline. For example, adding acidic ingredients like lemon juice or vinegar can increase the shelf life, while the addition of fresh herbs may shorten it due to their higher water content.
To maximize the shelf life of marinated mushrooms, follow these storage tips:
- Use a clean, airtight container: Store the marinated mushrooms in a clean container with a tight-fitting lid to prevent spillage and minimize exposure to air, which can cause spoilage.
- Keep the mushrooms fully submerged: Ensure that the mushrooms are completely covered in the marinade. This creates an anaerobic environment that inhibits the growth of spoilage-causing bacteria.
- Store in the refrigerator: Maintain a consistent temperature by storing the marinated mushrooms in the refrigerator. Aim for a temperature between 34°F and 40°F (1°C and 4°C).
- Monitor for signs of spoilage: Even with proper storage, marinated mushrooms can eventually spoil. Check for changes in smell, texture, or the growth of mould before consuming.
It's worth noting that the shelf life of marinated mushrooms also depends on the type of mushroom and the ingredients used in the marinade. Some varieties, like oyster mushrooms, may have slightly different storage requirements or optimal shelf lives. Additionally, while marinating can extend the shelf life of mushrooms, it's still best to consume them as fresh as possible for optimal taste and texture.
