Can You Freeze Mushrooms? ›

If you aren't making a dish that will cook for long enough to thoroughly heat and cook the frozen mushrooms, you can thaw them first by transferring them to the refrigerator overnight to soften. You can keep mushrooms in your freezer for up to 12 months. They can be added to dishes you're going to thoroughly cook.

Scrub and brush mushrooms to remove dirt (don't wash them as they can become soggy). You can slice them or leave whole (smaller mushrooms are best for the latter). Pop them onto a tray and freeze until solid, then transfer to a labelled resealable freezer bag, expelling any excess air. Use within a couple of months.

You can certainly freeze mushrooms fresh, but cook them beforehand for the best texture and flavor. Mushrooms are full of water and when they're frozen from fresh, they can end up soggy, mushy and all around unpleasant. Cooking them beforehand, though, removes some of that moisture and results in better mushrooms.

While you certainly can take fresh mushrooms straight from the package to the freezer, it's better to freeze mushrooms cooked than raw. Why? It's all about moisture. Because mushrooms contain so much water, defrosted raw mushrooms will be mushy and can have an unpleasant consistency in soups, pastas, and other dishes.

Place chilled, well-drained mushrooms in a single layer on shallow trays or pans. Place in freezer until firm, then quickly transfer to labeled bags or containers. If using rigid containers, no headspace is necessary. If using flexible bags or wrap, remove as much air as possible.

The secret to mushroom storage is that they stay fresh longer if you take them out of their container. Wrap them in paper towels placed in open plastic bags (paper bags are even better) and keep them in the fridge.

Mushrooms can be frozen to prolong their shelf life and reduce food waste, especially if you've purchased more mushrooms than you can use at one time. While freezing mushrooms may cause some nutrient losses and texture changes, these are slight and still allow the mushrooms to be used in many ways when you're ready.

Avoid plastic bags and sealed containers when storing mushrooms as the lack of air flow will speed spoilage. Whole, raw mushrooms will keep from 4-7 days in the refrigerator, while sliced mushrooms (stored the same way), will last 1-2 days.

Add a little oil or butter to brown them. The second method is to blanche frozen mushrooms by immersing them in boiling water for 20 seconds, then enjoy them as they are or use them in your recipes.

Benefits include extended shelf life, preserved taste, and nutritional value. With frozen mushrooms at their disposal, individuals can explore a world of culinary possibilities, such as grilled delights, soups & stews, and others.

Thawing frozen mushrooms

If using them in recipes where cooking time is short, it's best to thaw them first to remove any excess moisture. Place them in the fridge overnight or on the countertop for a few hours.

Move the frozen mushrooms to a freezer bag or (even better) a vacuum pack bag. Get as much air out as possible, seal. They will keep frozen for up to 12 months. Only thaw mushrooms when you're ready to use them, as refreezing can damage their flavor/texture.

Reader: Fresh mushrooms technically can be frozen. However, when thawed, they will be very mushy and nothing like fresh mushrooms — think frozen food. If you want to freeze them, clean and saute them first. They are best used in a heated dish or soup.

You might be wondering why not use plastic produce bags to store bulk mushrooms? The answer lies in moisture control. Those rolls of plastic produce bags can trap moisture, leading to a damp environment that degrades the quality of the mushrooms very quickly.

It's easy for mushrooms to teeter between drying out and becoming overly wet, even in the fridge. To prevent a soggy fate, you'll want to toss the mushrooms in a paper bag or a basket with a paper towel to soak up the moisture. Avoid storing mushrooms in the crisper drawer, where there's more moisture.

Mushrooms can be frozen raw. But for better texture, it's recommended to blanch or sautee them first. Individually freezing them on a tray before bagging them up will prevent them from clumping together, which will allow you to thaw only what you need at a time.

Avoid plastic bags and sealed containers when storing mushrooms as the lack of air flow will speed spoilage. Whole, raw mushrooms will keep from 4-7 days in the refrigerator, while sliced mushrooms (stored the same way), will last 1-2 days. Do not wash until ready to use.

Freezing will change the color and texture of mushrooms, making them both darker and softer.
