Mushrooms are a versatile ingredient, adding depth and body to a variety of dishes. However, their high water content means they are prone to shrinking during the cooking process. This is because mushrooms act like sponges, absorbing liquids and releasing their water content when cooked. While there is no way to completely stop mushrooms from shrinking, there are techniques to minimise this, such as cooking them whole on high heat to reduce the opportunity for water release, or steaming to maintain moisture.

What You'll Learn
Mushrooms are mostly water, so they shrink when cooked
Mushrooms are like sponges—they have a high water content, with some varieties containing as much as 90% water. When cooked, the water evaporates, leading to shrinkage. This is why mushrooms shrink during the cooking process, similar to what happens to spinach.
To minimize shrinkage, some recommend cooking mushrooms whole and for a shorter duration. However, it's important to note that there is no way to completely prevent mushroom shrinkage during cooking.
The type of mushroom and cooking method also play a role in how much shrinkage occurs. Wild mushrooms, such as shiitakes, maitakes, and chanterelles, are more susceptible to becoming waterlogged if washed before cooking. Therefore, it is advisable to clean them with a damp paper towel or brush instead.
When cooking mushrooms, it is recommended to use a high heat setting. A low to medium heat setting may cause the mushrooms to release water, resulting in a rubbery texture and diminished flavour. By cooking at a higher temperature, the mushrooms will brown and develop a more appealing texture and taste.
Additionally, the use of oil or butter is important when cooking mushrooms. Mushrooms are highly absorbent, and a sufficient amount of oil or butter will prevent them from burning. However, adding salt before or immediately after placing the mushrooms in the pan should be avoided, as salt draws out water from the mushrooms, making them rubbery and less flavourful. Instead, it is recommended to add salt towards the end of the cooking process.

Salt draws out water, so add it at the end
Mushrooms are like sponges—they're full of water, and when cooked, they release this water and shrink. This is why they are often rubbery and tough. To avoid this, it's important to control how much water is released during cooking.
Sofia Norton, RD, advises against adding salt to mushrooms before or immediately after putting them in the pan. Salt draws out water from mushrooms, causing them to simmer in their liquids and resulting in rubbery, flavourless mushrooms. Instead, Norton recommends adding salt towards the end of the cooking process, after the mushrooms have caramelised. This will help achieve the desired taste and texture.
To cook mushrooms properly, it's also important to use a high enough heat. Medium-high heat is recommended as it allows the mushroom's liquids to slowly evaporate while the mushrooms caramelise, building flavour. Cooking mushrooms on low to medium heat will cause them to release too much water, resulting in rubbery mushrooms with little flavour.
To summarise, when cooking mushrooms, avoid adding salt at the beginning of the cooking process as it will draw out water and cause the mushrooms to become rubbery. Instead, add salt towards the end of cooking, after the mushrooms have caramelised, to enhance their flavour and texture.

Don't wash mushrooms, they get waterlogged
Mushrooms are like sponges and will absorb any moisture they come into contact with. This is why they should not be washed before cooking, as they will become waterlogged and slimy. If your mushrooms are dirty, it is better to wipe them with a damp paper towel or brush them with a pastry brush.
When cooking mushrooms, it is also important not to overcrowd the pan. This is because mushrooms release a lot of water when cooked, and if they are crowded, they will stew and become soggy. Instead, cook them in batches, ensuring each mushroom has some space. This will allow the water to evaporate quickly and give the mushrooms a nice brown colour and flavour.
If you want to sauté mushrooms without releasing too much water, it is best to use a wide pan to maximise evaporation. You can also put them in a low oven for an hour before cooking to draw out some of the moisture.
Some people recommend sweating the mushrooms in a dry pan first to release their water, before adding fat and turning up the heat. Others suggest starting with no oil and cooking the mushrooms until the water leeches out and cooks off before adding oil.
It is worth noting that some people disagree with the advice to not wash mushrooms, arguing that washing does not significantly increase their water content. However, the general consensus among professional cooks and chefs is to avoid washing mushrooms to prevent them from becoming waterlogged.

High heat evaporates liquid and prevents shrinkage
When exposed to high heat, the cells in the mushrooms' fleshy caps and stems undergo rapid evaporation of their moisture content. This moisture loss causes the mushrooms to shrink in size. However, by controlling the heat and cooking method, you can minimize this shrinkage. Sautéing or stir-frying mushrooms over high heat can help prevent shrinkage. The high heat sears the mushrooms, creating a barrier that locks in moisture and flavor. This technique is often used in restaurants to achieve those beautifully browned, yet plump mushroom slices. When sautéing, ensure that your pan and oil are hot before adding the mushrooms. This creates a sear that seals in the juices.
Grilling is another high-heat cooking method that can yield delicious, slightly charred mushrooms with minimal shrinkage. Similar to the searing process, the intense heat of the grill creates a flavorful exterior while retaining the mushrooms' juicy interior. Threading smaller mushrooms onto skewers or using a grill basket for larger varieties can help ensure they don't fall through the grill grates. Oven-roasting is a further option for applying high heat and avoiding shrinkage. By roasting mushrooms at a high temperature, you can concentrate their flavor and achieve a desirable texture without significant shrinkage.
It is worth noting that while high heat is effective in preventing shrinkage, it is important not to overcook mushrooms, as they can become rubbery and lose their appealing texture. Aim for a balance between heat intensity and cooking time to achieve the best results. Additionally, remember that the type of mushroom and its initial moisture content can also impact shrinkage. Varieties like button, cremini, and shiitake mushrooms tend to have higher moisture content and are more prone to shrinkage, so they may benefit the most from these high-heat cooking techniques.
To summarize, applying high heat through methods like sautéing, stir-frying, grilling, or roasting can help prevent mushroom shrinkage by evaporating moisture and creating a flavorful exterior seal. However, always be mindful of cooking time to avoid overcooking, and consider the type of mushroom you are working with to make the most informed decision about your cooking method. With these techniques in mind, you can enjoy delicious, perfectly cooked mushrooms without the disappointment of shrinkage.

Steam or eat raw to maintain moisture
Mushrooms are like sponges and will soak up any moisture. They contain a lot of liquid, and the flavour comes out when this liquid is cooked out. If you are cooking mushrooms, it is best to avoid washing them as they will get waterlogged. Instead, use a damp paper towel or a pastry brush to clean them.
When cooking, it is important not to overcrowd the pan. Mushrooms need room for their liquid to evaporate. If the pan is too crowded, the mushrooms will steam and simmer in their liquid, resulting in a rubbery texture and little flavour. To avoid this, cook mushrooms in batches if necessary, ensuring they have enough space to cook properly.
When cooking mushrooms, it is best to use a medium-high heat. This will allow the mushroom's liquid to slowly evaporate while the mushrooms caramelize, giving them a nice brown colour. Cooking at a lower temperature will result in rubbery mushrooms that have simmered in their liquid.
If you are adding salt to your mushrooms, it is best to do so at the end of cooking. Adding salt at the beginning will draw out the water from the mushrooms, making them rubbery and tough.
If you want to maintain the moisture in mushrooms, steaming them or eating them raw is the best option. However, it is important to note that raw mushrooms may have an unpleasant texture and may not be as flavourful as cooked mushrooms. Additionally, some people may be allergic to raw mushrooms.
