Preheat your oven to 375°F (190°C) and grease a baking dish lightly with olive oil or cooking spray.
Clean the mushrooms with a damp paper towel and slice them evenly into approximately 1/4-inch thick pieces.
Mince the garlic and finely chop the shallot.
In a large skillet over medium heat, melt the butter. Add the garlic and shallot, cooking until fragrant and softened, about 2 minutes.
Add the sliced mushrooms to the skillet, stirring frequently. Cook for 5-7 minutes, or until they release their liquid and become golden brown.
Stir in the heavy cream, fresh thyme, salt, and black pepper. Cook for an additional 2-3 minutes until the cream slightly thickens.
Transfer the mushroom mixture into the prepared baking dish and spread it out evenly.
In a small bowl, combine the grated Parmesan, Gruyère, and panko breadcrumbs. Drizzle in the olive oil and mix thoroughly to form a crumbly topping.
Sprinkle the cheese and breadcrumb mixture evenly over the mushrooms in the baking dish.
Place the dish in the preheated oven and bake for 15-20 minutes, or until the topping is golden and bubbling.
Optional: Garnish with freshly chopped parsley before serving.
Serve hot as a delicious side dish or pair it with crusty bread for a comforting main course.
