Substitutions · 28 dishes here use it

Out of mushrooms

Water first, flavor second. Crowd the pan and they steam and stay squeaky; give them room and leave them alone and they brown and go meaty. Salt only after the browning starts.

Everything below is judged against that job. A swap that covers it is a swap; one that only looks similar is not.

4 of the 28 dishes here that mention mushrooms list it as optional — 14% of them. In those, the correct substitution is nothing.

What to reach for

Instead · 1

dried mushrooms, soaked

an ounce dried per half pound fresh, and keep the soaking liquid

What it gets you
More flavor than fresh, and the soaking water is the best stock in the kitchen.
What it costs you
Texture and volume. Rehydrated mushrooms are chewy and there are fewer of them than the weight suggests.

Instead · 2

eggplant, cubed and browned hard

one medium eggplant per half pound

What it gets you
A soft, savory, sauce-absorbing chunk that browns well and reads as substantial.
What it costs you
The umami, which was the point. Add soy, miso or tomato paste to make up the gap.

Instead · 3

zucchini or celery, for bulk only

one for one

What it gets you
Vegetable volume in a stew or a filling, cooked in the same window.
What it costs you
Everything mushrooms were bringing. This is padding, and it should only be used when the mushroom was padding too.

Where you can just leave it out · 4

These dishes list mushrooms as optional. They were written to work without it, so no ratio is needed and nothing has to be bought.

Where the swap will be tasted · 7

These need it and are short enough that nothing hides: 4 required ingredients or fewer, which makes mushrooms a quarter of what is in the pan. Make the swap a decision rather than a repair.

Check what else is in the pan

The company mushrooms keeps in this library, counted off required ingredients. A swap that argues with the top two is the wrong swap, whatever a chart says.
