Mushrooms are a versatile ingredient used in a variety of dishes, but they can be a little tricky to clean. The best method for cleaning mushrooms depends on the type of mushroom and the level of dirt present. Wild mushrooms, for example, are often full of forest debris and require a more rigorous cleaning process than cultivated mushrooms, which are usually grown in a sterile environment. While some sources recommend rinsing or soaking mushrooms in water, others advise against it, as it can make them waterlogged and affect the cooking process and taste. As such, many chefs recommend simply wiping mushrooms with a dry cloth or paper towel to remove any dirt, or using a brush to gently loosen and remove any stubborn debris.

What You'll Learn
Commercial mushrooms are grown in sterile conditions, so they don't need washing
Most mushrooms available in grocery stores are cultivated in indoor farms and not harvested from the wild. Commercial mushrooms are grown in sterile conditions, so they don't need to be washed before cooking. The soil in which they are grown is heat-treated at controlled temperatures to remove common plant pathogens like mold, bacteria, viruses, worms, bugs, and slugs. This process does not kill all microorganisms, but it eliminates most of them.
Research from Penn State's College of Agricultural Sciences supports this process, stating that the heat generated during the traditional composting process is adequate for eliminating human pathogens that might be present. Additionally, a study from the Research Group on Food of Plant Origin at the University of Zaragoza in Spain found that cultivated mushrooms had no traces of E. coli or Salmonella.
However, some people prefer to clean mushrooms before cooking, especially if there are visible patches of dirt and grime. The recommended method is to use a dry cloth, paper towel, or a pastry brush to wipe off any dirt. This is because washing mushrooms can make them waterlogged, potentially impacting the taste and texture of the dish.
If you choose to wash your mushrooms, it is important to do so quickly in lukewarm water, then drain them in a colander and blot them with a towel. Washed mushrooms should be cooked immediately as they do not keep well.

Wild mushrooms should be washed, then dried
Wild mushrooms, such as chanterelles or black trumpets, are typically foraged from the forest floor and are therefore likely to be dirty. As such, it is recommended that they are washed and then dried.
While cultivated mushrooms are typically grown in indoor farms in a heat-treated compost that is practically sterile, wild mushrooms are exposed to everything the forest has to offer, including bugs, wood chips, and pine needles. Therefore, it is crucial to wash them before consumption to remove any dirt and grime.
Some people argue that mushrooms should not be washed, as they can become waterlogged, which may affect the cooking process and the final texture and taste of the dish. However, experts like Alton Brown, Harold McGee, Robert Wolke, and Kenji Lopez Alt encourage washing mushrooms. Their experiments have shown that mushrooms absorb an insignificant amount of water, resulting in a negligible impact on cooking time.
After washing wild mushrooms, it is important to dry them thoroughly. This can be done by patting them with a clean cloth, paper towel, or kitchen towel. Drying the mushrooms helps remove any remaining moisture, ensuring they do not become waterlogged. It also helps to remove any lingering dirt or debris. Once dried, wild mushrooms can be stored in the fridge in a paper bag or cooked immediately, as washed mushrooms do not keep well for extended periods.

Cultivated mushrooms can be cleaned with a dry cloth or paper towel
When it comes to cleaning mushrooms, there are two schools of thought: either to wash them or not. Some people believe that washing mushrooms is a sin, as it can make them slimy, waterlogged, and difficult to brown when cooked. On the other hand, mushrooms are often dirty and covered in a peaty-smelling growing medium when purchased, so cleaning them is necessary.
The best way to clean cultivated mushrooms is to use a dry cloth or paper towel. Gently rub the mushrooms with a dry cloth or paper towel to remove any dirt or debris. If you want to go the extra mile, you can use a pastry brush or a mushroom brush, which is small and round with soft bristles, to gently brush away any dirt. This method is especially useful for mushrooms with exposed gills, such as portobellos and shiitakes, as they are more absorbent.
If your mushrooms are particularly dirty, you may need to rinse them with water. However, this should be done sparingly and only if necessary. If you do rinse your mushrooms, make sure to dry them thoroughly before cooking. You can blot them with a dry paper towel or lay them on a kitchen towel to air dry. It is important to remove excess moisture to prevent sogginess and promote even browning during cooking.
Additionally, it is recommended to clean and dry mushrooms before slicing them to avoid extra moisture absorption. It is also best to use washed mushrooms right away, as they do not keep well and can become slimy. Storing cleaned mushrooms in a brown paper bag in the fridge is ideal, as plastic bags can lead to condensation and slime.
By following these steps, you can effectively clean cultivated mushrooms with a dry cloth or paper towel, ensuring they are ready for your favourite mushroom recipes.

Mushrooms can become waterlogged and change in taste if washed
Mushrooms are a versatile ingredient with a unique taste and texture. However, they can be delicate and require careful handling and preparation. One of the most common questions about mushrooms is whether or not to wash them before cooking. The answer is not straightforward, as it depends on the type of mushroom and the level of dirt present.
Wild mushrooms, for example, are more likely to be dirty and require a good wash or even a soak to remove impurities. On the other hand, cultivated mushrooms are typically grown in sterile environments and compost, so a simple brush-off with a dry towel or mushroom brush is usually sufficient. It is worth noting that even cultivated mushrooms can sometimes be dirty and may need a more thorough cleaning.
The main concern with washing mushrooms is that they can absorb water, leading to a change in texture and taste. Waterlogged mushrooms can become slimy, rubbery, and less flavourful. As Sofia Norton, RD, explains, "Mushrooms should be slightly crispy and browned on the outside and tender on the inside. In other words, they need to be caramelized for maximum flavour and best texture." Therefore, it is crucial to ensure that mushrooms are thoroughly dried after washing to prevent waterlogging.
Some people prefer to avoid washing mushrooms altogether to prevent them from becoming soggy. Instead, they use a knife or a damp cloth to remove visible dirt or cut off any sections of the mushroom holding dirt, typically the base or end of the stem. This method ensures that the mushrooms remain dry and retain their desired texture and flavour when cooked.
While the decision to wash or wipe mushrooms may depend on personal preference and the level of dirt present, it is important to prioritise food safety. Cooking mushrooms kill any remaining germs, and commercial mushrooms are typically grown in heat-treated compost, ensuring they are safe for consumption. However, wild mushrooms may require more thorough cleaning to eliminate potential impurities. In conclusion, while mushrooms can become waterlogged and change in taste if washed, proper cleaning and drying techniques can help mitigate these risks and ensure a delicious final product.

Washing mushrooms can increase cooking time
Mushrooms are a versatile ingredient, but they do require some preparation before cooking. The method of cleaning mushrooms is often debated, with some chefs advising against washing them. The primary concern is that washing mushrooms can make them soggy, increasing cooking time and negatively impacting the dish's texture and flavour.
Mushrooms are like little sponges, and they can absorb a lot of water when washed. This extra moisture can lead to a rubbery, slimy texture and a diluted flavour. To avoid this, some chefs recommend simply brushing off dirt with a dry towel, cloth, or brush. This method is especially recommended for cultivated mushrooms, which are typically grown in sterile environments and do not require extensive cleaning.
However, not all mushrooms are created equal. Wild mushrooms, for example, are more likely to be dirty and may require a more thorough cleaning. In these cases, a quick rinse followed by thorough drying may be necessary. According to Joseph Rizza, Executive Chef of Prime & Provisions in Chicago, "All wild mushrooms should be washed and it is crucial to dry them out afterwards."
It's worth noting that modern farming practices significantly reduce the risk of contamination in commercially grown mushrooms. Soil is heat-treated to remove common pathogens, and cooking further eliminates any remaining germs. Therefore, the risk of foodborne illness from consuming unwashed mushrooms is relatively low.
In conclusion, while it is possible to wash mushrooms, it is essential to be mindful of the potential impact on cooking time and the final dish. Proper drying after washing is critical to mitigating this effect. As a general rule, a quick inspection and gentle cleaning with a dry cloth or brush are sufficient for most cultivated mushrooms. However, for dirtier wild mushrooms, a careful wash and thorough drying may be necessary.
