Preheat oven to 350 degrees F.
Toss shiitake mushrooms, 1 tablespoon oil, smoked paprika and salt in a medium bowl.
Spread out on a large rimmed baking sheet and transfer to the oven.
Bake, stirring and turning occasionally until the mushrooms are dried out and browned, 20 to 30 minutes. Cool on the baking sheet.
