Ingredients
Scale
Cheese Mixture
- 1 1/4 cups shredded Gruyère cheese
- 1/4 cup freshly grated Parmesan cheese
- 2 tablespoons freshly chopped parsley, plus more for garnish
- 1 tablespoon fresh thyme leaves
- 1/2 teaspoon garlic powder
Mushrooms and Seasoning
- 6 large portobello mushrooms, stems removed and sliced 1/2 inch thick
- Kosher salt, to taste
- Freshly ground black pepper, to taste
Additional
- 1/4 cup heavy cream
Instructions
- Prepare Cheese Mixture: In a medium bowl, combine shredded Gruyère, grated Parmesan, chopped parsley, fresh thyme leaves, and garlic powder. Toss together until well mixed to create the cheese and herb mixture.
- Layer Mushrooms and Cheese: Preheat your oven to 425°F (220°C). Arrange one-third of the sliced portobello mushrooms evenly in the bottom of a 2-quart baking dish. Season with kosher salt and freshly ground black pepper to taste. Sprinkle one-third of the cheese mixture evenly over the mushrooms. Repeat the layering process two more times, ending with a cheese layer on top.
- Add Cream and Cover: Pour the 1/4 cup of heavy cream evenly over the layered mushrooms and cheese. Cover the baking dish tightly with aluminum foil to keep the moisture in during baking.
- Bake Mushrooms: Place the covered dish in the preheated oven and bake for about 35 minutes, or until the mushrooms are tender and cooked through.
- Broil for Finish: Carefully remove the foil from the dish. Pour off any excess liquid that may have accumulated at the bottom to prevent sogginess. Place the dish under the broiler and broil for about 4 minutes or until the top is golden brown and bubbly. Watch closely to avoid burning.
Notes
- Use fresh herbs for the best flavor, but dried thyme can be substituted if fresh is unavailable (use about 1 teaspoon dried thyme).
- To make this dish vegetarian, ensure the Parmesan cheese is vegetarian-friendly (some contain animal rennet).
- For a creamier texture, you can add a little more heavy cream before baking, but avoid making it too watery.
- Serve hot as a side dish or a light main course with a fresh green salad.
- Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
