1. Preheat oven to 350°F and grease a baking sheet. Set aside.
2. Using a wet paper towel gently wipe mushrooms clean. Remove the stem and the gills from the mushrooms and finely chop the stems and gills.
3. Over medium heat add oil to a sauté pan. Once the pan is warm add diced onion, minced garlic, and finely chopped mushroom stems and gills. Sauté for 2 minutes and remove from heat.
4. Mix in the oregano, basil, thyme, cream cheese, sour cream, Mozzarella cheese, and crabmeat. Season with salt and pepper, to taste.
5. Spoon the mixture into each mushroom cap.
6. Sprinkle Parmesan cheese on top of each stuffed mushroom and bake for 30 minutes, or until golden.
7. Remove from oven and serve. Garnish with fresh parsley (optional)
