It takes on the flavours of herbs, garlic and other ingredients, making it easy to use as a side or a meat-free addition to a meal. With just 22 calories per 100 g and some protein, it is a light, versatile choice; sauté it with a little oil for a simple accompaniment.

Frequently Asked Questions About Cultivated Mushroom

Should you wash cultivated mushrooms?

Yes, rinse cultivated mushrooms briefly under running water if they have visible dirt, then dry them well. Avoid soaking them, since they can take up water and release more liquid while cooking.

How should you store cultivated mushrooms?

Store cultivated mushrooms unwashed in the refrigerator in a breathable paper bag. Trapped moisture in a sealed plastic container can make them spoil faster; clean them just before you are ready to cook.

Can you eat cultivated mushrooms raw?

Yes, fresh cultivated mushrooms can be eaten raw; slice them thinly for salads or sandwiches. Raw mushrooms may be harder for some people to digest, so choose cooked mushrooms if they cause discomfort.

Can you freeze cultivated mushrooms?

Yes, cultivated mushrooms can be frozen, but they may become soft and watery after thawing. For a better texture, sauté them first, let them cool, and freeze them in an airtight container.

Why do cultivated mushrooms turn brown after cutting?

Cultivated mushrooms can brown when their cut surfaces react with air; this change alone does not mean they have spoiled. Cook them soon after slicing, or add a little lemon juice to slow the discoloration.

Can you eat the stems of cultivated mushrooms?

Yes, cultivated mushroom stems are edible and can be cooked along with the caps. Trim off any dried or tough ends, then slice the rest into stir-fries, soups, omelets, or other dishes.

Do cultivated mushrooms need to be peeled?

No, cultivated mushrooms do not need peeling. Their thin outer surface is edible, so simply remove any dirt and trim the dry end of the stem; peeling wastes edible mushroom without improving it.

How do you cook cultivated mushrooms without making them watery?

Cook cultivated mushrooms in a hot pan without crowding it, so moisture can evaporate instead of steaming them. Add salt near the end of cooking, since it draws water out of the mushrooms.

Are cultivated mushrooms the same as white button mushrooms?

Usually, yes: white button mushrooms are the familiar small, pale cultivated mushrooms sold whole or sliced. Brown cremini mushrooms are a closely related variety, but they have a darker cap and a deeper flavour.

How can you tell if cultivated mushrooms have gone bad?

Discard cultivated mushrooms if they have a slimy surface, a strong unpleasant smell, or widespread mold. A little darkening by itself is not a reliable sign of spoilage, so check their texture and smell too.
