Dry mushrooms are a practical pantry ingredient with a long shelf life, but they are much more than a substitute for fresh mushrooms. Their flavour becomes concentrated during drying, bringing deeper umami, savoury, earthy and woody notes to sauces, soups, risotto and braised dishes. Once rehydrated, they become tender again; their soaking liquid, carefully strained, becomes a richly flavoured mushroom broth.
What are dry mushrooms?
Dry mushrooms are mushrooms that have been dehydrated shortly after harvest to preserve their natural qualities and prevent spoilage. Removing their water concentrates their aroma and savoury character, so a small quantity can bring considerable depth to a dish.
Fresh mushrooms are naturally high in water. Drying reduces their weight dramatically, intensifies their flavour and allows them to be kept in the pantry for far longer. When soaked, they absorb water again and release an aromatic infusion that can be used in cooking.
Plantin expertise
Plantin carefully selects and sorts its dry mushrooms for their appearance, texture and aromatic character. As mushrooms are a natural product, they may still contain traces of dust, fine sediment or grit, particularly in folds and hollow interiors*. The mushrooms are inspected before drying, but a brief rinse and proper rehydration at home remain essential.
Some mushrooms, such as morels, are dried on racks above a wood fire. This traditional process can develop a delicate smoky aroma, while preserving the mushroom’s natural woodland character.
*As a natural product, dry mushrooms may contain fine grit. Rinse, soak and strain the soaking liquid carefully before cooking.
How to rehydrate dry mushrooms
- Rinse briefly. Place the dry mushrooms in a sieve and rinse under cool, clean water to remove surface dust or loose grit.
- Soak. Transfer them to a bowl, cover with lukewarm water and leave for 30 minutes to 1 hour, until soft and supple. Larger mushrooms may need longer.
- Lift out the mushrooms. Remove them gently with a slotted spoon or your hands, rather than pouring the bowl through a sieve. This keeps any grit at the bottom of the soaking bowl.
- Prepare the mushrooms. Gently squeeze out excess water. Rinse once more if necessary, then trim or halve large mushrooms before cooking.
- Keep the soaking liquid. Strain the remaining liquid through a fine sieve lined with a clean cloth, paper towel or coffee filter. This clear, aromatic liquid is ideal for sauces, risotto, soups and braised dishes.
Use rehydrated mushrooms promptly. If soaking them for more than two hours, keep them refrigerated rather than at room temperature.
Storage conditions
Store dry mushrooms in their original sealed packaging or in an airtight container. Keep them in a cool, dry, dark place, away from sunlight, steam, heat and humidity.
Humidity can undo the effects of drying, making mushrooms soft and reducing their keeping quality. Do not use them if they feel damp or sticky, show signs of mould, or smell musty rather than clean and earthy.
The Plantin collection
Dry morels have delicate woodland, toasted hazelnut and lightly smoky notes. They pair especially well with gentle, creamy ingredients such as chicken, veal sweetbreads, eggs, asparagus, shallot, white wine and crème fraîche. Try them in French Pan-Seared Veal Sweetbreads with Morels, Chicken with Morels and White Wine, Cream of Asparagus Soup with Morels, or Poached Eggs with Creamy Morel Sauce. Always soak morels thoroughly, as their hollow centres can retain fine grit.
Dry porcini have an earthy, nutty and deeply savoury umami profile. They work well with butter, garlic, thyme, aged cheese, pasta, polenta, beef, veal and structured red wine. Use them in Beef Ramen with Tenderloin, Porcini and Lemongrass, Creamy Chicken with Porcini Mushrooms, or Veal Blanquette with Porcini and Black Winter Truffle. Their carefully strained soaking liquid is an excellent flavour base for stock, risotto, sauces and braises.
Composed of yellow boletes, oyster mushrooms and black fungus, this mix combines rounded woodland flavour with varied textures. It is especially good with butter, olive oil, garlic, shallot, onion, cream, stock, soy sauce and slow-cooked meat. Try it in Pressure-Cooker Boeuf Bourguignon with Forest Mushrooms, or add it to pasta, soup, risotto, stuffing and sauces for easy everyday depth.
Dry black trumpets offer elegant earthy, smoky and nutty notes with delicate sweet, fruity undertones. They pair well with cream sauces, pasta, rice, seafood, poultry and game, as well as shallot, garlic, parsley, tarragon and white wine. Use them in dishes where their distinctive fragrance can remain the focus, such as a simple pasta sauce, risotto or creamy seafood dish.
Dry porcini powder brings the deep earthy, nutty and umami-rich flavour of porcini in an instantly usable form. Stir it into sauces, soups, risotto, gravy, pasta or mashed potatoes, or lightly dust it over eggs, roasted vegetables, chicken, steak or Parmesan. Use sparingly: a small amount gives a dish rich savoury depth without adding whole mushroom texture.
