What You'll Learn
White mushrooms should be refrigerated at 35°F to 40°F
White mushrooms are a versatile ingredient with a delicate and perishable nature. Proper storage is essential to preserving their quality and flavour. The ideal temperature for storing white mushrooms in the refrigerator is between 35°F and 40°F. Keeping them at this temperature will help to prevent spoilage. Temperatures higher than this range can cause the mushrooms to spoil more quickly.
In addition to temperature control, there are several other factors to consider when storing white mushrooms. Firstly, humidity plays a crucial role. Mushrooms require a balance of humidity. Excessive humidity can lead to sogginess and mould, while too little humidity can cause the mushrooms to dry out. Therefore, it is important to maintain a consistent level of humidity in the refrigerator.
Another factor to consider is air circulation. Good air circulation helps prevent moisture buildup around the mushrooms, which can promote decay. To facilitate air circulation, it is recommended to store mushrooms in perforated packaging. This allows for air flow while retaining enough moisture to prevent the mushrooms from drying out.
Handling the mushrooms correctly is also important. It is recommended to minimise handling and avoid washing mushrooms until you are ready to use them. Washing mushrooms before storage can increase moisture and shorten their shelf life. Instead, it is advisable to wrap them in a paper towel or store them in a paper or brown bag, which can absorb excess moisture and prevent sliminess.
By following these storage guidelines, particularly maintaining a refrigerator temperature between 35°F and 40°F, you can ensure that your white mushrooms remain fresh and full of flavour for as long as possible.

They should be stored in a paper bag to avoid slime
When storing white mushrooms, it is important to keep them dry to prevent them from becoming slimy and spoiling. Mushrooms have a high water content, and their porous texture means they can easily absorb moisture from their surroundings.
One effective way to store mushrooms and prevent them from becoming slimy is to use a paper bag. Paper bags are breathable and can absorb excess moisture, helping to keep the mushrooms dry and fresh. They allow air circulation, which is crucial in preventing moisture buildup around the mushrooms. By absorbing moisture, the paper bag helps to maintain a suitable humidity level for the mushrooms, as too much humidity can lead to sogginess and mould.
When using a paper bag, it is recommended to keep the mushrooms in their original packaging and place the bag in the main compartment of the refrigerator, where the temperature is consistent, ideally between 35°F and 40°F. This storage method helps to extend the shelf life of the mushrooms, keeping them fresh for up to 7 to 10 days.
Additionally, it is important to avoid washing the mushrooms before storing them, as moisture is the number one enemy of fresh mushrooms. Instead, it is suggested to wrap the mushrooms in a paper towel and then place them in a bowl in the refrigerator if a paper bag is not available.

Whole mushrooms last longer than sliced
When it comes to storing white mushrooms, several factors can influence how long they last in the fridge. These include temperature, humidity, air circulation, handling, and packaging. The ideal temperature for storing mushrooms is between 35°F and 40°F (2-4°C). Humidity should be balanced, as too much can cause sogginess and mould, while too little can dry them out. Good air circulation prevents moisture buildup, and handling should be minimised to avoid premature spoilage.
Now, let's focus on the comparison between whole and sliced mushrooms:
Whole mushrooms tend to last longer than their sliced counterparts. This is primarily due to the difference in surface area exposed to air. When mushrooms are sliced, they have a larger surface area exposed to the air, which can accelerate spoilage. Whole mushrooms, with their compact form, have less surface area for air exposure, helping them stay fresh longer.
The recommended storage method for whole mushrooms is to keep them in their original packaging or a paper bag. Paper bags are ideal as they absorb excess moisture and prevent the mushrooms from becoming slimy. For optimal results, place the packaged mushrooms in the main compartment of your refrigerator, where the temperature remains consistent.
On the other hand, sliced mushrooms are best stored in an airtight container in the refrigerator. Sliced mushrooms have a shorter shelf life than whole mushrooms and should be used within three days of purchase. To extend their usability, consider freezing them, but remember that fresher mushrooms tend to freeze better, so it's best to freeze them sooner rather than later.
In summary, whole mushrooms offer the advantage of longer freshness due to their reduced surface area and optimal storage conditions in paper bags or original packaging. Sliced mushrooms, while convenient, require airtight containers and have a shorter shelf life, making them more suitable for immediate use or freezing if not consumed within a few days.

Cook before freezing to preserve quality
Fresh white mushrooms can last for about a week in the refrigerator before they start to spoil. To keep them longer, you can freeze them. However, freezing mushrooms may negatively affect their quality, texture, and nutritional value.
Cooking mushrooms before freezing them is an essential step to preserve their quality. Mushrooms are full of water, and freezing them fresh can make them soggy, mushy, and unpleasant. Cooking them beforehand removes some of that moisture, resulting in better-tasting frozen mushrooms. This process also stops enzyme action, which helps to preserve their quality.
To prepare mushrooms for freezing, start by cleaning them to remove any dirt. You can wipe them with a damp paper towel, brush them with a pastry brush, or give them a quick rinse with water, ensuring you dry them thoroughly afterward. Trim any woody parts from the stems, and cut larger mushrooms into uniform pieces, while smaller mushrooms can be left whole.
Next, cook the mushrooms by sautéing or steaming them. To sauté, use a small amount of neutral oil or butter in a pan over medium heat. Cook until the mushrooms are fork-tender and the pan is mostly dry. To steam the mushrooms, soak them in a bowl with a couple of cups of water and a teaspoon of lemon juice.
Once the mushrooms are cooked, allow them to cool completely. Then, spread them out on a cookie sheet and flash-freeze them. Once they are frozen, use a spatula to lift them from the cookie sheet and pack them into freezer-safe containers or bags. Leave a half-inch of headspace for expansion and squeeze out as much air as possible before sealing to prevent freezer burn. Frozen mushrooms can be stored for up to a year, although sooner is better to maintain quality.
When you're ready to use your frozen mushrooms, simply add them directly to your dish while cooking. There's no need to thaw them first!

Fresh mushrooms freeze better
Fresh mushrooms can be stored in the refrigerator for about a week. However, they can be stored for much longer periods if they are frozen. Freezing mushrooms is an easy way to preserve their fresh, woody flavor.
To freeze fresh mushrooms, start by selecting mushrooms that are nice and fresh. Avoid any that are shrivelled, slimy, darkened, mouldy, or give off an unpleasant odour. Next, clean the mushrooms to remove any dirt. You can do this by wiping them with a damp paper towel, brushing them with a pastry brush, or giving them a quick rinse with water. Be sure to dry them thoroughly, as mushrooms absorb moisture easily. Mushrooms that are larger than one inch across should be sliced or quartered. It is also important to cook mushrooms before freezing them, as this will stop enzyme action and preserve their quality.
Once your mushrooms are cleaned, dried, and cooked, you can freeze them in airtight containers or freezer bags. Label the containers with the date and contents, and use within a few months for the best quality. Frozen mushrooms can be cooked straight from frozen and are good in soups, stews, and pasta dishes. They can also be used in recipes such as veggie burgers, mushroom gravy, casseroles, and pizzas.
Freezing fresh mushrooms is a great way to reduce food waste and ensure you always have some on hand for your favourite dishes. They may change in colour and texture, becoming darker and softer, but they will still taste delicious!
