Fresh mushrooms can be pricey, and their shelf life is short. It is disappointing to find a slimy mess in the refrigerator where fresh mushrooms once were. The good news is that there are ways to prolong their shelf life. The best way to keep them fresh for as long as possible is to stash them in a paper bag or porous container in the refrigerator. This will allow for air circulation, which is necessary to extend the mushroom's freshness.

What You'll Learn
Raw mushrooms last 3-7 days in the fridge
Raw mushrooms can be stored in the refrigerator for 3 to 7 days. They should be wrapped in paper towels and stored in a paper bag on a shelf in the refrigerator. This is because mushrooms have a high water content and can act like a sponge, absorbing excess moisture and becoming slimy. Paper bags and unsealed plastic bags allow for air circulation, which is necessary to extend the mushroom's freshness. When trapped in a sealed container, mushrooms will become slimy and decay more quickly.
If you are not planning to use the mushrooms within a week, it is recommended to freeze them. Freezing mushrooms can cause water molecules to expand and burst, damaging the mushroom's cell walls and resulting in limp and mushy mushrooms once thawed. To prevent this, mushrooms can be cooked by sauteing or steaming before freezing.
It is also important to note that mushrooms should not be washed until ready to use. To clean mushrooms, brush off any dirt and quickly rinse under water, then pat dry.

Cooked mushrooms last 3-4 days
Fresh mushrooms can be stored in the refrigerator for 4-7 days if they are whole, and 1-2 days if they are sliced. They should be stored in a paper bag or porous container to prevent moisture from accumulating and spoiling the mushrooms.
Cooked mushrooms, on the other hand, will last 3-4 days in the refrigerator. They should be stored in an airtight container, as you would with any other cooked food. It is important to note that cooked mushrooms may expire sooner if they are included in a dish with ingredients that spoil quickly.
To extend the shelf life of fresh mushrooms, they can be frozen. Before freezing, they should be cooked, blanched, sautéed, poached, or steamed to help lock in their texture and flavour. They can then be frozen on a parchment paper-lined baking sheet and stored in an airtight, vacuum-sealed plastic bag. Frozen mushrooms will last for 9-12 months but may lose some nutritional value and become mushy when thawed.
Another option for extending the shelf life of mushrooms is to marinate them. Marinated mushrooms can be stored in a glass jar in the refrigerator for 10-14 days.

Paper bags prevent moisture
Fresh mushrooms can be stored in the refrigerator for up to 1-2 weeks. To maintain their freshness and prolong their shelf life, it is recommended to store them in a paper bag. Paper bags are highly effective in preventing moisture accumulation. They are designed to absorb excess moisture released by mushrooms as they age, keeping the mushrooms dry and slime-free. This is particularly important as mushrooms are susceptible to spoilage due to excess moisture.
Paper bags are a preferred option over plastic bags or sealed containers because they allow for air circulation, preventing the mushrooms from drying out too quickly. The porous nature of paper bags helps maintain the ideal humidity level, ensuring that the mushrooms remain fresh and edible for a longer period. Additionally, the absorption of moisture by the paper bag helps to prevent any moisture-related damage, such as leakage or product deterioration.
The use of paper bags for mushroom storage is a cost-effective solution. They are affordable and readily available, making them a practical choice for mushroom preservation. By investing in paper bags, you can reduce the risk of mushroom spoilage and make your produce last longer, ultimately saving money.
Moreover, paper bags offer an eco-friendly alternative to plastic packaging. They are made from biodegradable materials, contributing to sustainability efforts. By choosing paper bags, you can reduce your environmental impact and support environmentally conscious practices. Some paper bags are even designed with wax coatings or compostable linings, ensuring both moisture protection and environmental responsibility.

Freezing mushrooms
Fresh mushrooms can be stored in the refrigerator for up to a week, but they can also be frozen to extend their shelf life. Freezing mushrooms is a great way to reduce food waste, especially if you have leftovers or have bought more than you can use before they spoil.
Preparing Mushrooms for Freezing
Before freezing, it is important to wash the mushrooms to remove any dirt and debris. You should then trim the woody parts and stems. Mushrooms can be frozen raw, but this can affect their texture due to the water content. To preserve their texture, it is recommended to cook or steam the mushrooms before freezing. Cooking or steaming the mushrooms will also reduce their moisture content, helping to prevent sogginess.
Freezing Process
Once the mushrooms are prepared, cut them into equal-sized pieces so they cook evenly. Small mushrooms can be left whole. You can then sauté or steam the mushrooms. If steaming, place the mushrooms in a steamer basket over a pot of boiling water for 3-5 minutes. Transfer the mushrooms to an ice bath to cool, then strain and pat them dry. Place the mushrooms on a parchment-lined baking sheet and put them in the freezer. Once frozen, transfer the mushrooms to a freezer-safe container or bag, removing as much air as possible before sealing.
Using Frozen Mushrooms
Frozen mushrooms should be added directly to cooked dishes and should not be eaten raw. They can be thawed overnight in the fridge or tossed straight into a pan.

Don't wash until ready to use
When storing fresh mushrooms in the refrigerator, it is recommended that you do not wash them until you are ready to use them. This is because moisture is the number one enemy when it comes to keeping mushrooms fresh. Mushrooms have a high water content, and when stored in a damp container or bag, they can become discoloured, mouldy, and slimy.
To prevent this, it is best to store mushrooms in a paper bag or porous container in the refrigerator. The paper bag will absorb any excess moisture released by the mushrooms, keeping them fresh and slime-free for longer. If you do not have a paper bag, you can simply leave the mushrooms uncovered in the refrigerator. However, avoid using plastic bags or sealed containers as the lack of airflow will speed up spoilage.
If you are not planning to use the mushrooms within a week, it is recommended to freeze them. To do this, briefly steam or saute the mushrooms, then allow them to cool before storing them in a freezer-safe bag or container. Frozen mushrooms can be added directly to your dish while cooking, but they may not be suitable for frying into crispy pasta toppings as they may compromise in texture.
When you are ready to use the mushrooms, simply wipe off any dirt or quickly rinse them under water and then pat them dry. By following these storage tips, you can keep your fresh mushrooms lasting for up to a week or longer in the refrigerator.
