How to Cook Mushrooms
Six methods with real times, from a ten minute skillet of golden sautéed cremini to grilled portobello caps, plus when to salt so they brown instead of stew.
Most disappointing mushrooms come from the same two mistakes, a pan that is not hot enough and too many mushrooms in it. The result is grey, squeaky pieces sitting in liquid.
Mushrooms are around 90 percent water, so cooking them is really about driving that water off before the browning can start. Give them a wide hot pan and a few undisturbed minutes and they turn deep gold, firm, and genuinely savory. It happens fast once the liquid goes.
They are also one of the few plant foods with meaningful selenium and B vitamins, and USDA data puts a 100 gram portion at 22 calories with 3 grams of protein, which is why they work so well as a partial swap for meat. The charts below cover every common method and variety, with fixes for the usual problems.
Cooking times by method
Times assume button or cremini mushrooms, halved or sliced a quarter inch thick. Delicate varieties cook faster.
| Method | Prep | Heat | Time | Result |
|---|---|---|---|---|
| Sauté (skillet) | Halved or 1/4 inch slices | Medium high | 8–10 minutes | Deep golden edges, the everyday method |
| Roast (oven) | Halved or whole small caps, oiled | 425°F | 20–25 minutes | Concentrated flavor, chewy and meaty |
| Air fry | Halved, lightly oiled | 380°F | 10–12 minutes | Crisp outside with very little oil |
| Grill | Whole portobello caps or skewers | Medium direct | 8–12 minutes | Smoky, juicy, good as a burger swap |
| Broil | Stuffed or halved caps | Broiler, 6 inches away | 6–8 minutes | Fast browning for stuffed caps |
| Steam or simmer | Whole or halved | Simmering liquid | 5–8 minutes | Soft and mild, for soups and broths |
The 6-step sauté method
- 1.
Choose firm, dry caps
Good mushrooms feel firm and dry, with tight caps and no slick or shrivelled patches. Button and cremini are interchangeable, cremini just taste a little deeper. Shiitake need their stems removed, oyster mushrooms cook faster than either, and portobello are simply large cremini.
- 2.
Brush them clean instead of soaking
Wipe the caps with a damp cloth or give them a very quick rinse and pat them dry, in line with FDA guidance for fresh produce. Do not leave them sitting in water. Mushrooms are already about 90 percent water, and extra moisture on the surface is what stops them browning.
- 3.
Cut them thick and even
Halve small mushrooms, quarter large ones, or slice them about a quarter inch thick. Thin slices shrink to nothing and turn limp. Even pieces matter more than the exact shape, since ragged cuts mean some pieces burn while others are still raw.
- 4.
Heat the pan before the fat
Set a wide skillet over medium high and let it heat for a minute, then add a tablespoon of oil or a mix of oil and butter. A cold pan releases the water slowly and the mushrooms poach in their own liquid. Cast iron and carbon steel hold heat best here.
- 5.
Spread them out and leave them alone
Add the mushrooms in a single layer with a little space between them and let them sit for three to four minutes without stirring. They will release liquid, then reabsorb it. Cook in two batches rather than crowding one pan.
- 6.
Salt and season at the end
Once the pieces are browned on both sides, add salt, pepper, garlic, and a knob of butter or a few thyme sprigs and cook one more minute. Salting early pulls water out too soon. A splash of soy sauce, sherry, or lemon juice at the finish lifts the whole pan.
Times by mushroom variety
| Variety | Roast at 425°F | Other method | Notes |
|---|---|---|---|
| Button (white) | 20–22 minutes | Sauté 8–10 minutes | Mildest, the default for pastas and pizza |
| Cremini | 20–25 minutes | Sauté 8–10 minutes | Same shape, firmer and more savory |
| Portobello caps | 20–25 minutes | Grill 8–12 minutes | Scrape the gills if you want a cleaner sauce |
| Shiitake | 15–18 minutes | Sauté 6–8 minutes | Remove the woody stems, keep them for stock |
| Oyster | 12–15 minutes | Sauté 5–7 minutes | Crisps at the edges, tear rather than slice |
| Enoki | Not suited | Sauté 2–3 minutes | Trim the base, cook briefly so they stay springy |
Four habits that improve every batch
- Use the widest pan you own. Surface area, not heat alone, is what evaporates the water so browning can start.
- Wait through the wet stage. Every batch looks like it is boiling for a few minutes before the liquid cooks off.
- Deglaze the pan with a splash of stock, wine, or sherry once the mushrooms are browned, then pour it over whatever you are serving.
- Keep the stems. Shiitake stems and button trimmings add real depth to a stock or a soup base.
Fixing mushrooms that went wrong
Grey, rubbery, no color
Pan not hot enough or too full. Preheat properly and cook in two batches.
Swimming in liquid
Normal at first. Keep the heat up and let it evaporate before you add anything else.
Slimy texture
Washed and cooked while wet, or held too long after cooking. Dry the caps and serve soon after.
Tastes flat
Under salted or missing acid. Season at the end and add lemon, soy sauce, or a splash of wine.
Shrank to nothing
Sliced too thin. Halve or quarter instead of slicing when you want a meaty bite.
Burnt garlic
Garlic went in too early. Add it in the last minute, once the mushrooms are already browned.

Storing raw and cooked mushrooms
Keep raw mushrooms in the refrigerator in a paper bag or their original vented container. Sealed plastic traps moisture and turns them slimy within a day or two. Most varieties hold four to seven days, and slight browning is fine as long as the caps stay firm.
Cooked mushrooms keep three to four days in a covered container. Raw mushrooms freeze poorly, so sauté them first, cool them, then freeze them flat in a bag for up to three months and add them straight to pasta sauces, soups, and omelettes.
What to serve with them
A pan of browned mushrooms belongs next to anything savory. Spoon them over a seared steak, stir them into a pot of rice, or serve them beside baked chicken thighs. For a vegetable plate, add roasted asparagus or simmered lentils, and browse weekly meal plans when you want the week mapped out.
Mushroom FAQs
How long do mushrooms take to cook?
Sliced or halved mushrooms sauté in 8 to 10 minutes over medium high heat, roast in 20 to 25 minutes at 425°F, air fry in 10 to 12 minutes at 380°F, and grill in 8 to 12 minutes. Delicate types such as oyster and enoki need only 2 to 7 minutes.
How do you sauté mushrooms so they brown instead of steam?
Heat a wide skillet over medium high before adding oil, add the mushrooms in a single layer, and leave them undisturbed for three to four minutes. They release liquid first, so keep the heat up until it evaporates. Cook in two batches if the pan looks crowded, and salt only at the end.
Should you wash mushrooms before cooking?
Wipe them with a damp cloth or rinse quickly and dry them right away. Mushrooms absorb surface water, and wet caps steam instead of browning. Do not soak them and do not use soap or produce wash on them.
When do you salt mushrooms?
Salt them once they are browned, in the last minute or two. Salt draws water out of the caps, so adding it at the start floods the pan and delays browning. The same goes for garlic, which burns if it goes in early.
Do you need to peel mushrooms or remove the gills?
No peeling is needed for any common variety. Trim dry stem ends, remove the woody stems from shiitake, and only scrape the gills from large portobello caps if you want to keep a pale sauce from turning dark.
How long do cooked mushrooms keep?
Refrigerate cooked mushrooms in a covered container and use them within three to four days. Reheat them in a hot dry skillet so they firm up again rather than in the microwave. Store raw mushrooms in a paper bag in the refrigerator, not sealed plastic.
