Dried Black Trumpet Mushroom Recipes

Slofoodgroup Team December 10, 2022

Black trumpet mushrooms are so incredibly delicious—so delicious, in fact, that if you are lucky enough to have some on hand, you might have a hard time choosing just one thing to do with them. In most cases, dried black trumpet mushrooms will work in any recipe that call for a fresh version. The only difference is that you will need to rehydrate them first.

There are other instances when the dried version is actually more suitable than fresh. In today’s post, we will cover several instances where dried black trumpet mushrooms reign supreme and we will also include a recipe that uses black trumpet mushrooms not one, but two ways. 

When It’s Better to Use Dried Black Trumpet Mushrooms

  • Use dried black trumpet mushrooms for upping the umami flavor in your broth.
  • Dried trumpets are great as a rub for meats.
  • When a recipe calls for broth, dehydrate your mushrooms and save the liquid.
