Last Updated: November 25, 2021 References

Bunashimeji mushrooms grow in bundles with long stems and rounded caps. They have a lovely nutty, slightly buttery flavor. They stay firm and a little crunchy, even when cooked, so they’re a nice option if you want some added texture in a dish. You might commonly see them marketed or listed in recipes as “beech” mushrooms, and they’re also often used as substitutes for oyster or straw mushrooms.^{[1]

This is especially important for dishes where you want to get a little bit of everything onto your form or spoon for the best tasting bite.^{[4]

Toss the mushrooms and sauce with 1 pound (0.45 kg) of cooked pasta, adding 6 tbsp (85 grams) of unsalted butter to make sure the sauce covers all the noodles evenly.

1
Choose mushrooms that look firm and dry. If they appear soggy, slimy, or limp, leave them on the shelf! Fresh bunashimeji mushrooms have firm stems and caps. They’re usually sold in plastic-wrapped packages and come in little bundles.^{[15]

Research source}
- If you can’t find this variety at your local grocery store, check out an Asian market.
- You can usually find both white and brown bunashimeji mushrooms. Brown ones tend to be a little more bitter, but that bitterness goes away once they’re cooked.
2
Leave fresh mushrooms in their package and store them in the fridge. Leaving them wrapped preserves their freshness. If you opened a package of mushrooms but didn’t cook all of them, put what’s left in a resealable plastic bag and keep it in the fridge.^{[16]

Research source}
- If you get the mushrooms into the fridge straight from the store, they'll last for a few weeks. Once the package is open, try to use them within 7 days for the freshest taste.^{[17]

- Get rid of mushrooms that are slimy or smell funky.

Chop the base off of a cluster of bunashimeji mushrooms. These mushrooms are held together at the bottom so that they look like a small clump. Trim off the base so that the mushrooms fall away in individual pieces. The stems are totally edible, and it’s common practice to cook them along with the caps.^{[18]

- Always use a clean cutting board and kitchen knife to prep your ingredients.

Expert Interview. 9 November 2021.} Most bunashimeji mushrooms are already pretty clean because of how they’re grown, but it won’t hurt to give them a quick rinse before cooking them. Just put them in a colander or hold them in your hand while running a gentle stream of water over them.^{[20]

- If the mushrooms don’t look very dirty, just spot clean them with a brush or towel. It’s best to avoid getting mushrooms too wet before cooking because it can make them slimy.^{[21]
