Are mushroom stems okay to eat?

Mushrooms are a delicious and nutritious addition to many dishes. While most people eat the caps of mushrooms, the stems are often discarded. This leads many to wonder – are mushroom stems okay to eat? The short answer is yes! Not only are mushroom stems edible, but they also offer nutritional and culinary benefits. Like the caps, mushroom stems are low in calories, fat-free, cholesterol-free, and a good source of important nutrients. In this article, we’ll take an in-depth look at the reasons mushroom stems are good to eat, their nutrition facts, how to prepare them, and some delicious ways to use them in recipes.

Are Mushroom Stems Edible?

Mushroom stems are entirely edible. In fact, many professional chefs and knowledgeable home cooks make use of stems along with caps when cooking with mushrooms. The stems contain the same nutrients and have a similar texture and flavor to the caps once cooked. Sliced or chopped stems work well in any dish that calls for mushrooms. The only exceptions are woody or very thick mushroom stems that may need to be peeled and trimmed before cooking. With proper preparation, the stems of most common mushroom varieties are just as edible as the caps.

Nutrition Facts of Mushroom Stems

Mushroom stems have very similar nutritional value to mushroom caps. Here are some of the key nutrients found in both parts of mushrooms:

  • Vitamin B2 – Riboflavin is important for red blood cell production and converting food to energy.
  • Vitamin B3 – Niacin helps maintain healthy skin, nerves, and digestion.
  • Vitamin B5 – Pantothenic acid aids in producing hormones and cholesterol.
  • Phosphorous – Plays a role in bone health and energy production.
  • Potassium – Needed for water balance, nerve transmission, and muscle function.
  • Copper – Helps form red blood cells and keeps the immune system and nerves healthy.
  • Selenium – Has antioxidant properties that protect body cells from damage.

Mushrooms also contain some protein, carbohydrates, and fiber. A 1 cup serving of chopped mushroom stems contains approximately:

  • 21 calories
  • 4 grams protein
  • 4 grams carbohydrates
  • 1 gram fiber

This is quite similar to the nutritional profile of mushroom caps. So by using the stems along with caps, you get double the nutrition!

Benefits of Eating Mushroom Stems

Here are some of the top benefits of including mushroom stems in your recipes:

Extra Nutrition

As seen above, stems contain many of the same vitamins, minerals, and nutrients as caps. Using the whole mushroom gives you more nutrition per mushroom. This can help you meet the recommended daily intake levels for important nutrients like B vitamins, selenium, and copper.

More Fiber

The indigestible parts of mushrooms contain hemicellulose and chitin, both forms of dietary fiber. The stems are denser than the caps and provide extra fiber. Fiber promotes good digestion and heart health.

Additional Taste and Texture

Cooks often say the stems have the most intense mushroom flavor. Their firm, often chewy texture also gives dishes more variety. Stems hold up well when sautéed, roasted, or added to soups and stocks.

Reduce Food Waste

Throwing away mushroom stems means losing out on edible food. Making use of the entire mushroom is an easy way to reduce waste in the kitchen. Composting is another option if you don’t want to eat the stems.

Cost Savings

Since you can use up the entire mushroom, stems allow you to get more for your money from each mushroom purchased. This is perfect for stretching your grocery budget.

How to Prepare Mushroom Stems

Preparing mushroom stems for cooking or eating raw requires just a few easy steps:

Clean the Stems

Use a soft pastry brush or paper towel to clean away any dirt or debris clinging to the stem. Rinse or wipe the stems as needed. Make sure not to soak the mushrooms since excess moisture can affect texture.

Trim the End

Use a paring knife to trim away the very bottom of the stem where the mushroom was attached. Sometimes this end can be dried out or woody.

Peel If Necessary

Larger stems with tougher outer skin can be peeled. A paring knife or vegetable peeler easily removes the outer layer.

Slice, Chop, or Dice

Cut the stems into the size and shape needed for your recipe. Uniform pieces will cook evenly. Many cooks match the shape of the sliced stems to the caps.

And that’s it – the stems are now ready to cook and eat! They can be used raw in salads, sautéed, baked into casseroles, and any method you’d use for the caps.

Tips for Cooking with Mushroom Stems

Here are some top tips for getting the most flavor and texture from mushroom stems:

– Sauté stems in olive oil or butter before adding other ingredients. This caramelizes their natural sugars and brings out the umami flavor.

– Roast chopped stems in the oven at 400°F for 15-20 minutes to concentrate the mushroom essence.

– Simmer stems in broth for mushroom stock, then use the softened stems in soup.

– Use diced stems in place of ground meat in Bolognese sauce, tacos, etc. Their meaty texture works perfectly.

– To reduce chewiness, cook stems longer than caps in wet recipes like risottos and gravy.

– Powder dried stems in a spice grinder to make vegetarian mushroom “powder” that adds intense flavor.

– Pickle tough stems before using them in salads or grain bowls to soften the texture.

Taking a little extra time to prep and cook the stems can really maximize their flavor and enjoyment.

These recipes and cooking techniques all maximize the use of mushroom stems. Get creative in your own kitchen to take advantage of these under-appreciated yet nutritious parts of mushrooms!

Storing Excess Mushroom Stems

If you can’t use up all your mushroom stems right away, proper storage will keep them fresh for later use:

– Place cut stems in an airtight container in the refrigerator for 3-4 days.

– Freeze cut stems in an airtight freezer bag for 2-3 months. Use frozen directly in cooked recipes.

– Dry stems in a dehydrator or low oven until completely dried out, 6-12 hours. Store in an airtight container for up to 1 year. Reconstitute by simmering in liquid before using.

– Pickle stems in a vinegar brine to extend unrefrigerated shelf life up to 1 month stored in the brine.

– Immerse stems in olive oil in an airtight container in the fridge for up to 2 weeks for infused mushroom oil.

With a little planning, you can save those stems to add flavor to multiple dishes throughout the week. No mushroom bits need to go to waste!

Common Concerns About Eating Mushroom Stems

While most mushroom stems are perfectly edible, some people have concerns. Here are answers to some frequently asked questions:

Are the stems as tasty as caps?

This depends a bit on personal taste – some stems can be fibrous or chewy. But cooked properly, many people find the stems to have the deepest and richest mushroom flavor. The key is to use the right cooking method and preparation to bring out the best in stems.

Can eating raw stems cause digestive upset?

Some people report stomach discomfort from eating raw mushroom stems. Cooking them breaks down the chitin fiber to make digestion easier. People with sensitivity may be fine handling cooked stems but should avoid raw.

Do the stems contain toxins?

The stems contain the same amount of potential toxins as caps. With commercially grown edible mushroom varieties, this is not a concern. For wild foraged mushrooms, proper identification and cooking is important for all parts.

Could stems be contaminated or spoiled?

If mushrooms were not handled properly before purchase, both the stems and caps could have bacterial contamination. This is why proper washing is always important. The stems do not spoil more quickly than caps.

Are the stems as filling as the caps?

Some find the dense, fibrous texture of stems to be extra filling compared to caps. This can be beneficial for managing hunger and portion control.

Overall there are no major causes for concern when it comes to enjoying mushroom stems as part of a varied diet. Practice good food safety as you would with the caps or any produce item.


Mushroom stems deserve a place along with the caps in your recipes. Not only are they completely edible, but consuming the stems provides extra nutrition, fiber, and affordability. With proper preparation like trimming woody ends and slicing or chopping, the stems can be an tasty addition to all types of savory dishes. Use techniques like sautéing, simmering in liquid, or roasting to bring out the best texture and mushroom essence. Keep the stems for later by refrigerating, freezing, drying, pickling, or infusing in oil. With a little creativity, the stems can shine just like the caps in your cooking. Taking full advantage of the entire mushroom is economical, environmentally-friendly, and opens up many possibilities in the kitchen.
