Step 1

Put the mushrooms in a colander and shower them with water for about 20 seconds. Transfer them to a clean work surface, and wipe with a damp paper towel.

Step 2

Slice the mushrooms into ¼ inch slices.

Step 3

In a 9x13 inch baking pan, combine the mushroom jerky marinade ingredients.

Step 4

Transfer the mushrooms to the pan, and toss to fully coat in marinade. Cover the pan with cling film and refrigerate for 30 minutes to overnight.

Step 5

Preheat the oven to 250 F (125 C). Line a baking tray with parchment paper.

Step 6

Using tongs, remove the mushrooms from the marinade, allowing any excess to drip off. Space them out evenly on the baking tray.

Step 7

Bake on the middle shelf for 1 hour.

Step 8

Remove the tray from the oven, and flip the mushrooms. Rotate the tray in the oven and bake for an additional hour.
