How to Freeze Mushrooms: How It’s Done

Follow these simple steps to freeze your mushrooms and ensure they maintain their delicious flavor and texture:
Step 1: Clean the Mushrooms
Start by wiping down your mushrooms with a damp cloth to remove any dirt. Avoid washing them under running water, as mushrooms can absorb moisture, which can affect their texture during freezing.
Step 2: Slice the Mushrooms
Using a sharp knife, slice the mushrooms evenly. Aim for about 1/4-inch thickness to ensure they cook evenly when you use them later.
Step 3: Heat the Oil
In a skillet over medium heat, add 2 tablespoons of vegetable or olive oil. Allow the oil to heat up for a minute.
Step 4: Sauté the Mushrooms
Add the sliced mushrooms to the skillet and sprinkle a pinch of kosher salt over them. Sauté for about 5-7 minutes, stirring occasionally, until the mushrooms are tender and have released their moisture.
Step 5: Cool the Mushrooms
Once cooked, remove the mushrooms from the skillet and spread them out on a plate or baking sheet. Allow them to cool completely at room temperature.
Step 6: Pack for Freezing
Once cooled, transfer the mushrooms to freezer bags or airtight containers. Make sure to squeeze out as much air as possible before sealing to prevent freezer burn.
Step 7: Freeze
Label your bags or containers with the date and store them in the freezer. Your mushrooms are now ready to be used in your favorite recipes!
Budget & Availability Swaps

If you’re looking to substitute ingredients or save some money, consider the following options:
- Oil: Any neutral oil can work in place of vegetable or olive oil, such as canola or sunflower oil.
- Mushroom variety: Feel free to use any fresh mushrooms you have on hand, such as cremini, shiitake, or button mushrooms.
- Salt: If you prefer, you can use sea salt or table salt instead of kosher salt.
Flavor Logic
Freezing mushrooms while cooking them in oil not only preserves their flavor but also enhances it. The oil helps prevent freezer burn and keeps the mushrooms from becoming mushy. Additionally, sautéing the mushrooms brings out their natural umami flavor, making them even more delicious when you’re ready to use them in your dishes.
How to Store & Reheat
To ensure your mushrooms stay fresh and flavorful after freezing, follow these storage and reheating tips:
- Storage: Keep your frozen mushrooms in the freezer for up to 6 months for the best quality.
- Reheating: You can add frozen mushrooms directly to your cooking without thawing. They work great in soups, stews, and stir-fries.
- Thawing: If you prefer to thaw them first, do so in the refrigerator overnight or use the microwave on the defrost setting.
