Mushroom varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common mushroom varieties compare.

Variety	Best for
White Button	Everyday sautéing, soups, and pizza: mild and tender, the standard supermarket mushroom.
Cremini (Baby Bella)	All-purpose cooking: brown-skinned, firmer, meatier white-mushroom variety with deeper flavour. Sold as Cremini, Baby Bella, or Portobellini.
Shiitake	Asian dishes and stocks: woody stems, strong umami; sold fresh or dried.
Oyster	Quick sautés and stir-fries: delicate, fan-shaped caps that cook in minutes.
Chestnut	Roasting and risotto: nutty brown caps, firmer than white button, similar to cremini.
Porcini	Risotto, sauces, and stews: deeply savoury; usually sold dried and rehydrated.

Which should I pick?

For everyday sautéing, pasta, and risotto, Cremini (Baby Bella) gives deeper, meatier flavour than White Button. No Cremini? White Button is the reliable supermarket default. For stocks and stir-fries that want strong umami, reach for Shiitake; for tender quick sautés where you don't want the mushroom to overpower, Oyster.
