Step 1

Preheat the oven to 400 degrees F.

Step 2

Place the sliced mushrooms on a rimmed baking sheet. It is okay if they overlap a little bit because they will shrink as they cook.

Step 3

In a mixing bowl combine the melted butter, oil, vinegar, garlic, herbs, salt and pepper. Mix well.

Step 4

Drizzle the mixture over the mushrooms and toss to coat.

Step 5

Roast the mushrooms 10 minutes, turn and bake an additional 5-10 minutes until they reach your desired tenderness.

Step 6

Garnish with parmesan and additional herbs if desired.
