How Long Do Mushrooms Last in the Refrigerator? Find Out Now!

Mushrooms are delicious, versatile, and a great addition to many meals. But, like all fresh produce, they don’t last forever. If you’ve ever wondered how long mushrooms last in the refrigerator or how to store them properly, you’re in the right place! In this ultimate guide, we’ll break down everything you need to know about keeping your mushrooms fresh for as long as possible. Let’s dive into it!

The Lifespan of Fresh Mushrooms in the Refrigerator

Fresh mushrooms, whether white, brown, or cremini, are a bit of a mystery when it comes to how long they last in the fridge. If you’ve ever found a forgotten pack of mushrooms at the back of your fridge, you’ve probably wondered, “Can I still eat these?” Well, the shelf life of mushrooms depends on several factors, like their type, storage method, and whether they’ve been pre-cut. So, let’s break it down.

Fresh mushrooms generally last anywhere from 4 to 7 days in the refrigerator. However, this can vary depending on a few things:

  • Type of Mushroom: Different varieties of mushrooms have slightly different shelf lives. White mushrooms, for example, tend to spoil quicker than portobellos or shiitakes. Brown mushrooms (also called cremini) can last a little longer, but they’re all pretty similar when it comes to how fast they age.
  • Storage Method: How you store mushrooms plays a huge role in how long they last. If you leave them in their plastic packaging, they’ll likely start to spoil faster. However, if you store them properly, in a paper bag or in a container with a vent, they’ll stay fresh longer.
  • Pre-Cut vs. Whole Mushrooms: Pre-sliced mushrooms will spoil faster than whole mushrooms. This is because once the protective skin of the mushroom is broken, moisture can escape, leading to quicker deterioration. Whole mushrooms will last a bit longer since they’re still sealed.

Mushrooms are pretty sensitive to moisture, so they can spoil quickly if they aren’t stored well. When mushrooms get too soft, slimy, or discolored, it’s a sign they’ve passed their prime. At that point, it’s best to throw them out. If they’ve started to develop spots, they can still be usable if the rest of the mushroom is firm and clean.

How to Properly Store Mushrooms for Maximum Freshness

The key to making your mushrooms last as long as possible in the fridge is all about how you store them. It’s easy to make a few simple changes to your storage habits, and they can go a long way in extending the life of your mushrooms. Here’s how to do it:

1. Keep Them in a Paper Bag

Instead of leaving mushrooms in the plastic container they came in, transfer them to a paper bag. Paper is breathable and allows the mushrooms to release moisture, which prevents them from becoming slimy and moldy. If you don’t have a paper bag, you can also use a cardboard box or a container with ventilation holes to achieve the same effect.

2. Avoid Storing Mushrooms in Plastic

Plastic traps moisture, which can lead to faster spoilage. If your mushrooms are in a plastic bag or container, they may start to sweat and become slimy within a few days. So, switching to paper can make a big difference in keeping them fresh.

3. Store Whole Mushrooms, Not Pre-Cut

If you’re not planning to use all your mushrooms at once, it’s best to keep them whole. Cutting them exposes the interior of the mushroom to air, and moisture escapes, leading to faster spoilage. If you’ve already sliced your mushrooms, try to use them within a day or two.

4. Don’t Wash Mushrooms Before Storing

It’s tempting to rinse mushrooms before storing them, but you should avoid this. Mushrooms are highly absorbent, so washing them can make them soggy. Instead, just wipe them with a dry paper towel to remove any dirt before storing them in the fridge.

5. Keep Them in the Main Part of the Fridge

Store your mushrooms in the main section of the fridge, not in the crisper drawer. The crisper is meant for fruits and vegetables and can sometimes be too humid for mushrooms. The main part of the fridge is usually a bit drier and a better spot for them.

6. Check Regularly for Spoilage

Even though you’re storing mushrooms the right way, it’s still important to check them every day or so for signs of spoilage. If you notice any mushy, slimy, or discolored spots, remove those mushrooms immediately to prevent them from affecting the others.

By following these simple steps, you can extend the shelf life of your mushrooms and keep them fresh for as long as possible. Now that you know how to store mushrooms, let’s talk about the different signs to look for when they start to go bad.

Signs That Your Mushrooms Are Spoiled

It’s always disappointing when your mushrooms go bad before you get a chance to use them. However, there are a few signs that indicate your mushrooms have passed their prime, and it’s time to say goodbye to them. Here are the most common signs of spoiled mushrooms:

1. They’re Slimy or Wet

One of the easiest ways to tell if mushrooms have gone bad is by feeling them. Fresh mushrooms should feel firm to the touch. If they’re slimy, wet, or mushy, it’s a sign that moisture has built up, which encourages mold growth. When mushrooms feel this way, it’s best to toss them.

2. They’ve Changed Color

Mushrooms are usually a nice white or brown color, but when they start to spoil, they can turn dark or develop spots. If you notice that your mushrooms have turned an unappealing color (like brown, black, or yellow), they’re no longer fresh. Some discoloration is normal, but once it spreads, the mushroom is no longer safe to eat.

3. They Have a Strong Odor

Mushrooms have a mild, earthy smell when fresh. However, if they start to smell sour, rotten, or overly strong, it’s a sure sign that they’ve gone bad. The smell is usually an indication of mold or bacteria growing on the mushrooms, and it’s best to throw them away.

4. They’re Wrinkled or Shrunken

Fresh mushrooms should look plump and moist. If they start to shrink, wrinkle, or dry out, they’re no longer fresh. Mushrooms that are dried out or shriveled are typically past their prime, and eating them may not taste very good.

5. They Have Mold

If you spot any mold on your mushrooms, that’s an obvious sign that they should be thrown away immediately. Mold can spread quickly on mushrooms, and even if only a small portion of the mushroom has mold, it’s better to be safe and discard the entire batch.

Now that you know what to look for, it’s time to explore how to tell if mushrooms are safe to eat and what to do with any leftovers.

Can Mushrooms Be Frozen to Last Longer?

If you’ve bought a large batch of mushrooms or simply want to save some for later, freezing them is an option. Freezing mushrooms can extend their shelf life for up to a year. However, there are a few important things to keep in mind to ensure your mushrooms freeze well and taste good once thawed:

1. Clean and Slice Before Freezing

To freeze mushrooms, you need to clean them first. Wipe off any dirt with a damp cloth or paper towel. Avoid rinsing them under water, as mushrooms can absorb moisture. After cleaning, slice the mushrooms into even pieces. This makes them easier to use later on in recipes.

2. Blanch Before Freezing

Blanching mushrooms before freezing them helps preserve their texture, flavor, and color. To blanch mushrooms, simply bring a pot of water to a boil, then drop the sliced mushrooms in for about 2 minutes. After blanching, quickly place the mushrooms in a bowl of ice water to cool them down. Drain well before freezing.

3. Freeze on a Tray First

To prevent mushrooms from clumping together, spread them in a single layer on a baking sheet or tray and freeze them for a couple of hours. Once frozen, transfer the mushrooms to a freezer-safe bag or container. This method ensures they stay separated and easy to use later.

4. Use Within a Year

Frozen mushrooms can last up to a year in the freezer. However, the texture may change slightly when thawed, so it’s best to use them in cooked dishes like soups, stews, or stir-fries.

5. Thaw Carefully

When you’re ready to use your frozen mushrooms, you can cook them directly from frozen without thawing, or you can thaw them in the fridge overnight. Thawing them at room temperature may cause them to become too mushy, so it’s best to thaw in the fridge for better texture.

Freezing mushrooms can be a great way to keep them around longer, but make sure to follow the steps above to keep them tasting fresh when you thaw them.

I hope this article helped you understand how long mushrooms last in the fridge and how to store them properly. Fresh mushrooms are a wonderful addition to many dishes, and with the right care, they can last longer than you think. Keep them dry, store them in paper bags, and make sure to check for signs of spoilage. If you have extra mushrooms, freezing them can be a great way to save them for later. Happy cooking!
