Mushroom Powder Seasoning Blend

Create a mushroom powder seasoning blend, similar to Trader Joe’s Umami Powder. But this one is so easy to adapt to your own tastes made from your own dehydrated mushrooms!

This blend is something that I developed based on many renditions of the Trader Joe Umami blend but made it my own. Our family LOVES this on popcorn. Even more than when we use pickle powder.

Suggested Uses

  • Use as a rub for most meaty proteins
  • Flavor popcorn – seriously – better than pickle powder, and we like that stuff, too!
  • Make a gravy
  • Make a seasoned aoli – blend with mayo and some garlic
  • Use to flavor bread or crackers
  • Use to replace mushrooms in soups, stews, casseroles, rice, etc.
  • Create a vegetable and chip dip with sour cream, garlic, and caramelized onions pieces
  • Use to elevate meals in a jar spice blends
  • Use in meatloaf or meatballs
  • Use in scrambled eggs or fritatta dishes
  • Add to vegetable dishes – our personal favorite is to roasted potatoes or green beans. But it’s also fabulous on just about anything!
  • Use in anything savory – the umami quality of mushroom powder, especially the seasoning blend – gives a different level of flavor to just about everything!

Best Mushrooms for Mushroom Powder

My personal take is whatever safe mushrooms you can get your hands on, use them. However, price plays into this in that bulk creating mushroom powder from very expensive mushrooms can be cost-prohibitive.

The more flavor a mushroom has, the better suited for mushroom powder. But even with the simple Button Mushroom, the dehydrated mushroom powder is amazing. We actually prefer it over dehydrated mushrooms in our meals.

  • Button
  • Cremini
  • Shitaki
  • Portobello
  • Oyster
  • Porcini
  • Chicken of the Wood
  • Oyster
  • Any foraged mushroom that is safe to eat

There are so many varieties to choose from and not all are listed here. My criteria are usually how much powder will get (which is why I don’t use Enoki or Beech – they are saved for drying and cooking).

I generally look for bulk alternatives since I make this once a year.
