How to Clean White Button Mushrooms

Before we get cooking, it’s essential to start with clean mushrooms.

  1. Gentle Brushing: Gently brush the mushrooms with a soft-bristle brush or a paper towel. This will help remove any loose dirt or debris from the mushrooms.
  2. Trim the stems: If the mushroom stems are dry or have tough ends, trim them with a knife. You want to keep the tender part of the stem while discarding any tough bits.
  3. Avoid Soaking: It’s important not to soak button mushrooms in water. Mushrooms are like sponges and can absorb excess moisture, affecting their texture and flavor. Instead, use a damp paper towel or cloth to wipe the caps and clean up any remaining dirt.

Warming up leftover mushrooms is easy!


  • Place the desired portion of the mushrooms in a microwave-safe dish.
  • Cover the dish to prevent splatters and microwave on medium heat for 1-2 minutes, stirring halfway through. Keep an eye on them to avoid overcooking, as mushrooms can become rubbery if reheated too long.


  • Heat a skillet or pan over medium heat.
  • Add some butter or oil to the pan for flavor and moisture.
  • Transfer leftover mushrooms to the pan and stir-fry for 3-5 minutes or until heated. Stir occasionally to ensure even heating.
