Preheat your oven to 425 degrees. Line your pan with parchment paper.
Quarter your mushrooms and place on your prepared pan.
Drizzle desired amount of oil on to the mushrooms. Add the seasonings and toss to coat.
Bake for 15 minutes. Remove from the oven and flip them around. Place back in the oven until they are starting to brown, about 5-7 more minutes.
