Directions
Place one oven rack on lowest level and one rack on the next level above.
Heat oven to 500 degrees F.
Forty minutes before roasting the steak and mushrooms, use a fork to prick the potatoes once or twice each.
Place them directly on the sides of the upper rack of the oven, allowing enough room for the mushrooms, which will cook on the same rack.
Put the garlic in the blender or food processor with 4 tablespoons of the oil.
Blend until smooth. Scrape down the sides with a rubber spatula.
Add remaining oil and salt and pepper.
Blend until smooth. Put the mushrooms in a 12x8x1½-inch roasting pan.
Using the spatula, scrape out half the garlic mixture into the pan.
Rub the purée into both sides of each mushrooms cap.
Allow to marinate for at least 30 minutes.
Put steak in shallow container large enough to hold it.
Pour remaining garlic mixture over and rub into both sides of steak.
Let marinate on kitchen counter at least 30 minutes or until meat comes to room temperature.
Before roasting the steak and mushrooms, put a roasting pan on the lower oven rack and preheat for 10 minutes.
