Ingredients
Scale
Cheese Mixture
- 1 1/4 cups shredded Gruyère
- 1/4 cup freshly grated Parmesan
- 2 tablespoons freshly chopped parsley, plus more for garnish
- 1 tablespoon fresh thyme leaves
- 1/2 teaspoon garlic powder
Mushrooms
- 6 large portobello mushrooms, stems removed and sliced 1/2 inch thick
- Kosher salt, to taste
- Freshly ground black pepper, to taste
- 1/4 cup heavy cream
Instructions
- Preheat Oven and Prepare Cheese Mixture: Preheat your oven to 425°F (220°C). In a medium bowl, combine shredded Gruyère, grated Parmesan, chopped parsley, fresh thyme leaves, and garlic powder, tossing them together to evenly distribute the herbs and seasoning within the cheese.
- Layer Mushrooms and Cheese: Lightly season one-third of the sliced portobello mushrooms with kosher salt and freshly ground black pepper, then spread them evenly in the bottom of a 2-quart baking dish. Sprinkle one-third of the prepared cheese mixture over the mushrooms. Repeat this layering process two more times to create three layers of mushrooms and cheese.
- Add Cream and Bake Covered: Pour 1/4 cup of heavy cream evenly over the layered mushrooms and cheese. Cover the baking dish tightly with aluminum foil and bake in the preheated oven until the mushrooms are tender, about 35 minutes.
- Broil to Finish: Carefully remove the foil, then pour off any excess liquid from the bottom of the dish to prevent sogginess. Place the dish under the broiler and cook until the top is golden brown and bubbly, approximately 4 minutes. Watch closely to avoid burning.
Notes
- For a richer flavor, use freshly grated cheeses rather than pre-shredded.
- Slicing mushrooms evenly ensures uniform cooking.
- Make sure to drain excess liquid before broiling to get a perfect crispy top.
- Feel free to garnish with additional fresh parsley before serving for a pop of color and freshness.
- This dish pairs beautifully with roasted meats or can serve as a hearty vegetarian main.
