How to Make Scalloped Portobello Mushrooms

Preheat your oven to 425°F. An exciting adventure awaits! Start by warming up your kitchen, creating the perfect atmosphere for the delightful aroma that will soon fill the air.
Mix the cheese mixture. In a medium bowl, combine the shredded Gruyère, grated Parmesan, chopped parsley, thyme, and garlic powder. This mix will be the essence of your dish, blending beautifully together.
Layer the mushrooms. Begin by arranging one-third of your sliced portobello mushrooms in a 2-quart baking dish. Season with a sprinkle of kosher salt and freshly ground black pepper to enhance their natural flavor.
Add the cheese mixture. Sprinkle one-third of your cheese blend over the mushroom layer. Repeat the layering process two more times, using the remaining mushrooms and cheese mixture until fully satisfied!
Pour heavy cream. Gently drizzle the heavy cream over the layered mushrooms. This will create a creamy, dreamy sauce as it bakes, coating every bit with rich flavor.
Cover the dish with foil. Place it in your preheated oven and bake for about 35 minutes, or until the mushrooms are tender and have absorbed all those delicious flavors.
Broil to perfection. Once baking is done, remove the foil and carefully pour off any excess liquid from the bottom of the dish. Broil for about 4 minutes until the top is a beautiful golden brown.

Optional: Garnish with additional parsley for a fresh pop of color.
