Mushroom Powder Adds Umami to All Kinds of Dishes—Here's How to Use It

Mushroom powder offers a simple way to infuse umami into a variety of your home-cooked meals, from breakfast egg scrambles to late-night chocolate treats. This versatile ingredient, as convenient as the spices already in your pantry, boasts a range of flavors from mild and subtle to bold and strong.

Andrea Gentl, author of Cooking with Mushrooms, is on a mission to share that secret with home cooks everywhere. She's a fervent fungiphile, and a proponent, a zealot even, of the power of mushroom powders to improve your everyday cooking. She uses them constantly, in all manner of savory dishes, and a surprising number of sweets, and ahead, she is here to teach you how to do the same.

Mushroom Powder Is an Umami Bomb

Gentl devotes a section of her book to drying fresh mushrooms and pulverizing them into powders. Dehydrating brings out a "deep umami flavor," she says. And though you can find several varieties of cultivated mushrooms year-round in grocery stores and online, many more interesting varieties appear only seasonally, and briefly at that.

"Drying the varieties with short seasonal windows is a great way to preserve these flavor bombs," Gentl says. "And the new dishes you can dream up are endless once you have an array of them on hand."

Among the easiest ways to start experimenting with the flavor profiles of mushrooms is to dry them into powders. Gentl likes the ease of adding powdered mushrooms to dishes because they boost flavors in a concentrated way, even more so than fresh varieties do in many recipes. "I am layering in another flavor profile without adding another textural component," she says.

Why Homemade Mushroom Powder Is Best

You can, of course, buy dried mushroom powders and blends at specialty grocers, health food stores, and directly from some farmers and foragers at greenmarkets, but making your own couldn't be easier.

It's also a nice way to use up dried mushrooms you may already have in your pantry. Perhaps there's half a package of dried porcini at the back of a cabinet left over from a pasta recipe, or a few stray shiitakes that didn't make it into a miso soup.

Gentl recommends storing dried mushrooms in glass jars, then pulverizing them once you have amassed a few handfuls' worth. You can make single-variety powders, though Gentl recommends creating a few custom blends.

She combines oyster mushrooms, maitakes, and lion's mane in an all-purpose everyday powder, and tailors others to more specific uses, like a super health-boosting adaptogenic powder (with reishi, codyceps, and lion's mane) and a mix of maple-forward candy caps and earthy porcini that works especially well in chocolate desserts.

How to Make Mushroom Powder

Use a spice grinder, food processor, or blender (or a mortar and pestle if you're the patient, meditative type) to make your own mushroom powder:

1. Place the dried mushrooms in the spice grinder and pulse or grind them to a powder.
2. Sift the powder through a mesh sieve, remove any large pieces, and buzz or grind again till the powder is uniformly fine.
3. Transfer the powder to a glass jar with a tight-fitting lid, seal and label, and store in your refrigerator or freezer.

The powder should last indefinitely, but Gentl recommends putting it to use immediately.

How to Use Mushroom Powder in Your Cooking

The list of possibilities for cooking with mushroom powders is indeed endless, but here are a few ideas to get you started:

• Add a few pinches to the mix the next time you make granola, or toss with vegetables just before roasting.
• Use the powders to flavor broths, soups, stews, and curries.
• Make a dry rub for meat, poultry, or fish.
• Mix a compound butter with mushroom powder, coarse salt, and chopped herbs.
• Whisk a teaspoon or so into the dry ingredients for brownies or spice cookies.
• Sprinkle a little onto your morning eggs, however you like them (scrambled, fried, omelet, frittata).
• Use as a seasoning when making a stir fry for extra umami flavor.
• Add to any meat when cooking to enhance the flavor.

One of Gentl's favorite ways to put the powder to use is by making mushroom salt, which adds umami at the finish of nearly any savory dish. Fittingly, she uses it to salt the rims of cocktail glasses she uses for her signature mushroom cocktails, including a margarita, a Negroni, and a French 75. It's yet another way to celebrate the world of flavor to be found in a few handfuls of mushrooms.
