Equipment

1 baking sheet
1 large mixing bowl
1 sheet parchment paper
1 air fryer optional

Ingredients

5 ounces fresh oysters mushrooms
⅛ teaspoon kosher or fine salt and pepper
3 Tablespoons cooking oil like light olive oil, avocado, etc
2 tablespoons all purpose flour or equivalent
1 teaspoon spice mixture (optional or to taste) like blackening spice, a homemade spice blend, or a pinch of garlic powder, paprika and onion powder.

Instructions

Mix the salt and black pepper, flour, and seasoning of your choice (if using). I use blackening spice made without salt.
Preheat the oven to 400F. Clean the oyster mushrooms. generally they're very clean and may only need to be brushed with a paper towel.
Separate oyster mushrooms into bite sized pieces or small clusters, then toss with the oil. Most mushrooms I leave whole. Gently toss the mushrooms with the seasoned flour.
Lay the mushrooms out without overlapping on a baking sheet lined with parchment paper or large cast iron pan.
Oven roast the mushrooms in a preheated 400F oven for 20-25 minutes. Taste a mushroom, they should golden brown and crispy. If needed, keep them in the oven for another 5 minutes if they're large.
Remove the mushrooms and allow to cool in the pan, then remove to a container and store at room temperature for up to 2 days.
The mushrooms can be reheated gently in the oven to re-crisp them, but as long as most of the water has been cooked out and it wasn’t raining when you picked them they should keep a reasonably crisp texture.

Notes

Tips

This can also be made in an air-fryer.

Play with the seasonings and make your own blend. I use a teaspoon of homemade blackening spice without salt, but a good pinch of paprika, garlic powder and onion powder is fine too. Chopped fresh herbs like thyme, rosemary and sage work too.

Depending on your mushrooms, their moisture content and your oven, you may need to bake them a little more or less, or make a batch or two to tweak the crispness and flavors to your taste.
