Oyster Mushroom

Nutrition

Oyster mushrooms contain roughly 20 kilocalories, 1.9 grams of protein, and 2.3 grams of dietary fiber per 100 grams, along with various B vitamins and minerals like potassium and phosphorus, all with very little fat — an excellent value for a low-calorie, high-fiber ingredient.

How to Choose

Fresh oyster mushrooms have intact, crack-free cap edges, a gray-brown or light-gray color, and tightly packed white gills, with a texture that feels resilient rather than sticky when touched. Caps that are overly large, yellowed, or curled and dry at the edges have usually been sitting too long, and their flavor will suffer.

Cooking

Oyster mushrooms are best hand-torn before stir-frying, dry-frying, or simmering into soup — tearing, rather than cutting, preserves the natural fiber texture and lets the mushroom absorb flavor more evenly. A quick stir-fry over high heat locks in moisture and keeps them crisp-tender, while a long simmer draws out a deep mushroom fragrance, making them a common base ingredient for vegetarian stock.

Storage

Oyster mushrooms have a high water content and shouldn’t be washed before storing. Wrap them in a paper bag or paper towels and refrigerate, using them within 2 to 3 days. Alternatively, blanch, drain, and freeze them to extend storage up to about a month.

Tips

Oyster mushrooms come in many varieties — gray, white, and black being the most common — with slightly different flavors but largely similar nutrition and uses, so feel free to choose based on what’s available locally. When hand-tearing, follow the direction of the fibers to get evenly sized strips; this helps them cook more evenly and gives a better chew. Oyster mushrooms also absorb oil readily, so keep an eye on how much you use to avoid an overly greasy dish.
