There's nothing like the taste of fresh mushrooms. Whether they're sliced raw for salads, sautéed in garlic and olive oil, or stuffed with breadcrumbs, their rich, umami flavor makes them the star of many dishes. The fact that they're nutritious makes them even better.
If you're a mushroom lover, then you know how easy it is to go overboard at the supermarket or farmer's market. While piles of porcini mushrooms and cartons of cremini in the fridge might seem like heaven, fungi typically last less than a week in the fridge.
Fortunately, there is a solution that doesn't involve eating a bowl of mushrooms instead of cereal for breakfast or tossing them in the garbage: You can freeze your mushrooms.
Chef Rhonda Plummer, owner of the San Francisco-based private chef and catering service Cater2uSF, says to cook mushrooms before freezing for the best taste and texture.
"Although you can freeze raw mushrooms, they can become mushy when thawed, given their high water content," says Plummer. "They work well in soups, casseroles, and other blended dishes, but you may not want squishy mushrooms for other things."

Plummer says she uses various methods of freezing mushrooms depending on the types of mushrooms she's currently got in her kitchen. Her go-to for most mushrooms is steam blanching, a quick-cooking process that allows the mushrooms to keep their color and flavor, as well as their meaty texture.
"How long you blanch them will depend on the size, so it's good to sort them first or cut them up into smaller chunks before steaming," she says.

Freezing mushrooms raw will cause them to take on a softer texture once thawed. It's still possible to preserve them this way, though they'll be better suited for adding to soups and sauces rather than eating them on their own. Here's how to do it:
Clean and prepare the mushrooms. You can freeze them whole or slice them, depending on how you want to use them later after they are thawed. Spread them apart on a parchment-lined baking tray and freeze. Separating the mushrooms will allow them to freeze individually rather than in a large clump.
Once they're frozen, remove them from the tray and transfer them to freezer-safe bags. Return them to the freezer until you need them.

If you plan on making mushrooms the star of your dish, it's better to cook them first before freezing. Sautéeing is another go-to method for bringing out the flavor.
Heat up some olive oil in a skillet over medium heat, then add mushrooms in an even layer. Cook them until they are golden brown on one side, about three to four minutes. Flip them over, then brown the other side for another three to four minutes.
Remove the mushrooms from the heat and let them cool to room temperature. Transfer them to freezer-safe bags or containers. If you prefer, you can freeze them first on a tray as with the raw mushrooms to keep them separated.
When you are ready to use your frozen mushrooms, Chef Rhonda says you can cook with them still frozen if they're going straight into soups or sauces. Again, mushrooms have a high water content, so the additional water from any ice that has formed won't be a problem.
If you want to enjoy the mushrooms on their own, it's better to defrost them first — just take them from the freezer and put them in the refrigerator overnight.
Frozen mushrooms can keep for 9 to 12 months. For the best taste and texture, Chef Rhonda doesn't let her frozen fungi get past the four-month mark. If you like mushrooms, you probably won't let them stay in your freezer for that long anyway.
If you've got extra mushrooms on your hands that you don't want to waste, freezing them is an excellent option to keep them around longer. Whether you freeze them raw or cook them first depends on how you want to eat them later, but this method allows you to enjoy them later, if you choose.
