Scalloped Portobello Mushrooms

Langkah-langkah

1. Preheat oven to 400°F (200°C). In a medium bowl, toss together Mozzarella, Gruyère, Parmesan, parsley, Italian seasoning, onion powder and garlic powder. Set aside.
2. Remove stems from portobello mushrooms and slice into 1/2-inch (1-cm) slices.
3. Arrange one-third of mushrooms in the bottom of a 2-quart (2-litre) baking dish. Sprinkle with one-third of the cheese mixture. Season with salt and pepper. Repeat layering two more times.
4. Mix together cream and minced garlic and pour mixture over mushrooms.
5. Cover with foil and bake until mushrooms are tender, (about 30 minutes). Remove foil and carefully pour out excess liquid from the bottom of the dish into a small pot. Set pot aside.
6. Return mushrooms to the oven and broil/grill until golden, (about 4-5 minutes).
7. Bring mushroom pan juices in the pot to a simmer over medium-high heat.
8. Mix 1 teaspoon cornstarch with 1 tablespoon water and whisk in cornstarch mixture until fully combined.
9. Continue to simmer while stirring until gravy has thickened.
10. Serve with mushrooms.
