Preheat oven to 400.
Wipe mushrooms clean with a damp paper towel. Cut lengthwise through the stems into 1/4 inch thick slices.
Lightly spray or wipe a baking dish with about 1 tsp of the olive oil.
Heat the remaining olive oil and butter in a medium skillet. Add the bread crumbs and cook over medium heat, stirring until the crumbs are coated and begin to brown, about 5 minutes. Stir in the garlic, thyme, salt, paprika and pepper.
Stir over medium heat until the garlic is translucent, 1 to 2 minutes.
Sprinkle the crumb mixture evenly over the mushrooms.
Bake 25 minutes, or until the mushrooms are tender.
Serve hot or at room temperature.
