How to freeze mushrooms (2024)

FAQs

What is the best way to freeze fresh mushrooms? ›

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.

Insert wrapped mushrooms inside a Ziploc-type freezer bag. (4 portions will fit in a quart-size bag.) Press out as much air as possible as you seal the bag. Or, insert the wrapped mushroom portions into plastic or glass freezer container.

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.

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.

Defrost them, I use hot water, get them dry, then either pan fry them in oil using high heat or bake them. Nothing that gets cooked in water / microwave is going to be crisp.

To freeze mushrooms, briefly steam or sautee, then allow them to cool before storing in a freezer-safe container. Make sure you label the container! They will keep their peak quality up to 10-12 months.

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.

Yes. You can use regular zip-top storage bags in the freezer. However, foods stored in these bags in the freezer might not hold up as well over long periods of time, and can be more prone to punctures and rips.

Why can't you store mushrooms in plastic? ›

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.

There are two options: pan-fried or blanched. The first method is to cook frozen mushrooms the same way you would fresh, without thawing. If you want to chop them up, however, let them thaw for 15 minutes. Then, cook them in a very hot pan over high heat without fat, until all the water in the mushrooms has evaporated.

Before freezing, wash mushrooms to get rid of any dirt and debris, trim the woody parts and stems, and cut them into equal-sized pieces, so they cook or steam evenly. If freezing an exact amount for a recipe, like the mushrooms for beef stroganoff, there's no need for step 5 in the cooking method.

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.

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.

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.

Clean and Prep

Mushrooms more than one-inch across should be sliced or quartered. Freezing will change the color and texture of mushrooms, making them both darker and softer.

Move the frozen mushrooms to a freezer bag or (even better) a vacuum pack bag. Get as much air out as possible, seal, and keep them frozen until you're ready to use. 6. Only thaw mushrooms when you're ready to use them, as refreezing can damage their flavor/texture.
