Preheat your oven to 190°C (375°F).
Clean the mushrooms using a damp paper towel and slice them thinly.
Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the diced onion and cook for 3-4 minutes until translucent.
Stir in the minced garlic and cook for another 30 seconds, or until fragrant.
Add the sliced mushrooms to the skillet. Cook for about 6-8 minutes, stirring occasionally, until the mushrooms release their moisture and start to brown.
Season the mushroom mixture with salt and black pepper. Stir to combine, then remove the skillet from heat.
In a mixing bowl, combine the cooked mushrooms and onions with the low-fat sour cream, shredded mozzarella cheese, and fresh parsley.
Transfer the mixture into a lightly greased casserole dish, spreading it out evenly.
In a small bowl, mix the panko breadcrumbs with the melted butter and the remaining 1 tablespoon of olive oil. Sprinkle this mixture evenly over the casserole to form a crispy topping.
Place the casserole dish in the preheated oven and bake for 20-25 minutes, or until the top is golden brown and bubbling.
Remove from the oven and let it cool for 5 minutes before serving. Garnish with a little extra parsley, if desired.
