Most common grocery store mushrooms are good to eat, and several specialty varieties offer standout nutritional or health benefits. White button, cremini, portobello, shiitake, oyster, maitake, and lion’s mane are all widely available, safe, and worth adding to your meals. Each brings a slightly different mix of nutrients and flavors to the table, so the best approach is to eat a variety.
White Button, Cremini, and Portobello
These three are actually the same species harvested at different stages of growth. White buttons are picked young, creminis are a slightly more mature brown version, and portobellos are left to grow to full size. They’re the most widely sold mushrooms in the world and a solid nutritional choice: about 3 grams of protein and 2 grams of dietary fiber per 100 grams, along with 358 mg of potassium (roughly 8% of what most adults need daily).
Portobellos deserve a special mention for vitamin D. Most mushrooms contain almost none unless they’ve been exposed to ultraviolet light, but UV-treated portobellos can deliver 446 IU or more per 100 grams. That’s over twice the baseline daily recommendation for most adults. Some producers achieve even higher levels, up to 750 IU per 100 grams, depending on how long the mushrooms are exposed to UV during processing. If you see “UV-treated” or “high vitamin D” on the label, that’s what it means. You can also boost vitamin D at home by placing sliced mushrooms gill-side up in direct sunlight for 15 to 30 minutes before cooking.
Shiitake
Shiitake mushrooms have a rich, savory depth that makes them one of the most popular cooking mushrooms worldwide. They’re meatier than button mushrooms and hold up well in stir-fries, soups, and braises.
Beyond flavor, shiitake contain a compound called lentinan, a large polysaccharide that activates immune cells. Research published in Scientific Reports found that lentinan boosts the activity of macrophages (the immune cells that patrol your body for invaders) and supports T cell function. It’s one of the reasons shiitake has been used in traditional medicine for centuries, and modern research continues to confirm that regular consumption supports immune health. You get the most benefit from cooked shiitake, as heat helps break down the tough cell walls and release these compounds.
Oyster Mushrooms
Oyster mushrooms have a delicate, slightly sweet flavor and a tender texture that works beautifully sautéed or roasted. Nutritionally, they stand out in a few ways compared to white button mushrooms. They contain more iron (0.91 mg vs. 0.22 mg per 100 grams), more niacin (5.87 mg vs. 2.80 mg), more riboflavin, more thiamin, and more magnesium. They’re also slightly higher in dietary fiber at 2.7 grams per 100 grams.
Oyster mushrooms naturally contain lovastatin, the same compound used in cholesterol-lowering medications. The amounts in a typical serving are far smaller than a pharmaceutical dose, but regular consumption may contribute modestly to heart health over time, particularly as part of a diet already rich in vegetables and whole grains.
Maitake
Also called “hen of the woods” because of its layered, feathery appearance, maitake is prized in Japanese cooking and increasingly available at specialty grocers and farmers’ markets. It has an earthy, peppery flavor that intensifies when roasted or grilled.
Maitake is the vitamin D champion among mushrooms. When grown under UV light, maitake can contain a remarkable 2,242 IU of vitamin D2 per 100 grams. Even without UV treatment, some growing methods yield meaningful amounts. Like other mushrooms, maitake is also rich in beta-glucans, the fiber compounds linked to immune support and better blood sugar regulation.
Lion’s Mane
Lion’s mane looks nothing like a typical mushroom. It grows in shaggy, white, icicle-like clusters and has a flavor often compared to crab or lobster when cooked in butter. It’s increasingly available fresh at farmers’ markets and in supplement form.
What sets lion’s mane apart is its effect on the brain. It contains compounds that stimulate the production of nerve growth factor, a protein your body uses to grow, maintain, and repair neurons. These compounds are found both in the fruiting body you eat and in the root-like mycelium. A narrative review in the journal Nutrients confirmed that these bioactive compounds exhibit neuroprotective effects, acting as antioxidants and reducing inflammation in nervous tissue. While most of the research has been conducted in lab settings and animal models, the existing evidence is strong enough that lion’s mane has become one of the most studied functional mushrooms for cognitive health.
Morels
Morels are a seasonal delicacy that appears in spring and early summer, with a wild harvest window of just a few weeks. They have a hollow interior, a honeycomb-like cap, and a deeply savory, almost nutty flavor that’s unlike any other mushroom. Chefs prize them for their umami intensity, which comes from high levels of natural glutamic and aspartic acids.
Nutritionally, morels punch above their weight. They contain higher amounts of potassium, zinc, and selenium than most common mushrooms. Some varieties are especially rich in iron (up to 53 mg per 100 grams in certain species), calcium, and magnesium. They also naturally contain vitamin D2 at about 204 IU per 100 grams without any UV treatment, making them one of the few foods that provide meaningful vitamin D on their own. Morels should always be cooked before eating, as they contain compounds that can cause stomach upset when raw.
Chanterelles
Chanterelles are golden, trumpet-shaped mushrooms with a fruity, peppery aroma. They’re foraged rather than farmed, which makes them seasonal and more expensive, but their flavor is considered among the finest of any edible mushroom. Like morels, chanterelles are a natural source of vitamin D2, containing about 212 IU per 100 grams even without UV exposure. They pair well with eggs, pasta, cream sauces, and light meats.
Cooking Matters More Than You Think
Mushroom cell walls are made of chitin, the same tough material found in insect exoskeletons. Your digestive system can’t easily break it down, which means eating mushrooms raw gives you access to fewer of their nutrients. Cooking, whether sautéing, roasting, grilling, or simmering in soup, softens that chitin and makes the protein, minerals, and beneficial compounds inside more accessible to your body.
Sautéing in a small amount of oil is one of the best methods because many of mushrooms’ beneficial compounds are fat-soluble. Roasting at high heat concentrates flavor and creates caramelized edges without destroying the heat-stable B vitamins and minerals that mushrooms are known for. Boiling works for soups and broths, though some water-soluble nutrients will leach into the cooking liquid, so using that liquid in your dish helps you retain them.
A Note on Foraging
If you’re thinking about gathering wild mushrooms rather than buying them, proceed with extreme caution. Many deadly species closely resemble edible ones. The Amanita family, which includes the death cap and destroying angel, has caused the majority of fatal mushroom poisonings worldwide. These mushrooms have white spore prints, the same color produced by several edible species, so spore color alone is not enough to confirm safety.
To make a spore print, cut the stem flush with the cap, place the cap gill-side down on paper, cover it with a glass, and wait two to three hours. The color of the spore deposit helps narrow down the family a mushroom belongs to, but it’s just one piece of the identification puzzle. If you’re new to foraging, go with an experienced guide or join a local mycological society. Never eat a wild mushroom unless you are completely certain of its identity.
The FDA requires that any substance used in food meet the “generally recognized as safe” standard. In 2024, the agency specifically warned against consuming Amanita muscaria and its extracts, citing hundreds of poison control calls and reports of seizures, hallucinations, and hospitalizations. Stick to well-known edible species from reputable sources, and when in doubt, buy from a store or trusted grower.
