Instructions

Preheat the oven to 400 degrees fahrenheit.

In a medium bowl, combine parmesan, gruyere, mozzarella, parsley, italian seasoning, salt, pepper, and onion and garlic powder.

Cut stems off of portobello mushrooms and slice into ½ inch slices.

Layer about a third of the mushrooms in the bottom of a 2-quart baking dish. Sprinkle with roughly one third of the cheese mixture. Repeat with two more layers of each.

In a medium bowl, mix cream and garlic. Pour mixture over mushrooms in the baking dish.

Cover the baking dish with foil and bake for about 30 minutes, until mushrooms are fork tender.

Remove foil and carefully pour out excess liquid from the bottom of the dish into a small pot.

Broil mushrooms until golden, about 3-4 minutes.

While mushrooms are broiling, bring a small pot of mushroom liquids to a simmer over medium heat. Mix 1 teaspoon cornstarch with 1 tablespoon water and whisk until fully combined. Add cornstarch mixture to mushroom juices, stirring and allowing to simmer to thicken.

Notes

Keep an eye on the mushrooms while they are broiling to ensure they don’t brown.
