Whether you’re prepping for a season of adventure, reducing food waste, or building a self-sufficient pantry, dehydrating mushrooms is one of the simplest projects you can start today. They add deep, savory flavor to soups, stews, gravies, eggs, and skillet meals. When you dehydrate and store them properly, mushrooms can last for years instead of days in the fridge.

Why Dehydrate Mushrooms?
Fresh mushrooms go bad fast. They get slimy, soft, and unusable in just a couple of days. If you are spending a significant amount of time off grid, (camping or living off-grid) it can be very difficult to keep mushrooms fresh.. Plus, it will also save you money because you don’t have to pay electricity to keep them in the fridge or ice for a cooler! Dehydrating mushrooms solves these problems!
Dehydrated mushrooms are:
- Lightweight (perfect for backpacking and road-tripping)
- Shelf-stable for years
- Easy to use in everyday cooking
- A great way to preserve bulk buys or foraged mushrooms
- Shockingly fast to dehydrate compared to other vegetables
If you’re building a pantry that works anywhere (RV, cabin, tent, van, or home) mushrooms should have a spot in your pantry. Want a free Pantry Starter Guide to help build your pantry the easy way? Click Here!
Best Types of Mushrooms for Dehydrating
You can dehydrate nearly any mushroom variety. These are the best performers:
- Button mushrooms
- Cremini or baby bella
- Portobello
- Shiitake (a favorite for flavor)
- Oyster mushrooms
- Morels and chanterelles
Tools & Equipment
- Dehydrator (This one and this one are the two I use)
- Mesh trays for small pieces – (This one and this one are the two I purchased)
How to Prep Mushrooms for Dehydrating
This is one of the easiest foods to prepare.
- Clean them without water (yes, really) – Mushrooms are like sponges, they absorb water instantly. Instead, wipe them with a damp towel or use a soft brush. If they’re very dirty, rinse quickly and pat dry thoroughly.
- Slice evenly – Slice mushrooms ¼ inch thick. Thin slices dry faster and more evenly. Whole mushrooms take longer and may not dry consistently.
Dehydrating Mushrooms in a Dehydrator
- Set your dehydrator to 125°F – 135°F (52°C – 57°C).
- Load Trays – Place the mushrooms on your dehydrator tray in a thin even layer. Don’t stack or overlap the mushrooms, this will cause them to take longer to dehydrate and dehydrate inconsistently.
- Drying Time: 6-12 Hours. It all depends on the dehydrator you have, the thickness of your mushrooms, and the humidity.
- How to know they’re done: They should be completely dry, brittle and snaps easily. There should be no leathery or bendy spots.

Storing Dehydrated Mushrooms for Long-Term Storage
If you want true long-term storage, these are the best containers:
- Mason jars with oxygen absorbers
- Mylar bags with 2 absorbers
- Airtight jars with gasket lids
Keep them in a cool, dark place away from humidity.
How to Use Dehydrated Mushrooms
You can leave the mushrooms as they are or blend them into a powder. You can toss the mushrooms or powder straight into:
- Soups
- Stews
- Gravy
- Rice dishes
- Pasta sauce
- Stir-fries
- Skillet meals at camp
They will rehydrate while cooking.
To rehydrate before cooking:
- Soak mushrooms in boiling hot water with a lid for 15–20 minutes.
- Use the soaking liquid as broth for incredible flavor.
Final Thoughts
Dehydrating mushrooms is one of the easiest, quickest, and most budget-friendly ways to build a lightweight, long-lasting pantry that actually works on the road or off-grid. Mushrooms add flavor to nearly everything, take almost no time to prep, and store well for years when packed correctly.
If you’re building out your own self-sufficient pantry, dehydrated mushrooms are an easy win that pays for itself over and over again.

Dehydrated Mushrooms
Whether you’re prepping for a season of adventure, reducing food waste, or building a self-sufficient pantry, dehydrating mushrooms is one of the simplest projects you can start today.
Instructions
- Clean them without water - Mushrooms are like sponges, they absorb water instantly. Instead, wipe them with a damp towel or use a soft brush. If they’re very dirty, rinse quickly and pat dry thoroughly.
- Slice evenly - Thin slices dry faster and more evenly. Whole mushrooms take longer and may not dry consistently.
- Thin even layer - Place the sliced mushrooms on the dehydrating trays in a thin even layer. If they are piled up, the one's underneath will not dry as quickly or evenly as the ones on top.
- Set your dehydrator to 125°F – 135°F (52°C – 57°C).
- Load Trays - Place the mushrooms on your dehydrator tray in a thin even layer. Don't stack or overlap the mushrooms, this will cause them to take longer to dehydrate and dehydrate inconsistently.
- Drying Time: 6-12 Hours. It all depends on the dehydrator you have, the thickness of your mushrooms, and the humidity.
- How to know they’re done: They should be completely dry, brittle and snaps easily. There should be no leathery or bendy spots.
Storing Dehydrated Mushrooms
Store them in an airtight container in a cool dark place. Here are some storing options.
- Mylar bags with 2 absorbers
- Airtight jars with gasket lids
Notes
- To make the slicing of the mushrooms so faster you can use a mandoline slicer.
- To rehydrate you will need to place the mushrooms in hot water until rehydrated. If you throw them in soup they will rehydrate while cooking the soup.
