Knowing how to clean mushrooms properly is essential for successful cooking. Like many kitchen techniques, it’s simple once you know the right method.
Mushrooms are one of my favourite vegetables. Their earthy, umami flavor enhances a wide range of dishes, and a well-cooked mushroom delivers a texture that’s hard to replicate.
Because mushrooms grow in soil, they often arrive with dirt and grit. Cleaning them correctly preserves both flavor and texture—done poorly, and delicate varieties can turn to mush.
Many people instinctively soak mushrooms in a bowl of water or rinse them under the tap when they have a large quantity to clean. Avoid this. Mushrooms are mostly water and highly porous, so they absorb liquid like a sponge. Immersing them will dilute their flavor and ruin the texture, especially for delicate wild mushrooms from a farmers’ market.
The best way to clean mushrooms is to wipe them with a damp paper towel, removing dirt and debris without soaking the flesh. For more stubborn grime or for wild mushrooms with crevices, use a soft nail brush or a clean toothbrush to gently scrub away the soil. Hearty varieties such as chestnut or portobello tolerate a firmer scrub, while delicate mushrooms need extra care.
Cooking mushrooms properly follows cleaning. Because they contain so much water, mushrooms should be cooked over high heat. If added to a cold pan, they will release their moisture and steam, leaving them soft and pale. When the pan is hot, mushrooms sear on contact. The high heat causes their released water to evaporate quickly, producing golden-brown, flavorful mushrooms that retain good texture.
After shopping, clean mushrooms as soon as you get home and store them properly. Transfer mushrooms purchased in plastic containers into a paper bag or wrap them in paper before refrigerating. Plastic traps moisture and speeds spoilage, causing mushrooms to become slimy.
I typically keep mushrooms unwrapped in a bowl in the fridge so they’re ready to use. They’ll keep best when stored dry and aired, and used within a few days. If you have favorite mushroom recipes, feel free to share them—sautéed, roasted, in soups or salads, mushrooms are versatile and delicious.
