Ingredients

• 2/3 cup finely chopped onion
• 1/4 cup extra-virgin olive oil, plus 2 tablespoons for garnish
• 1/4 cup balsamic vinegar
• 1 teaspoon chopped fresh rosemary leaves, plus sprigs for garnish
• 1 teaspoon chopped fresh oregano leaves, plus sprigs for garnish
• 1 teaspoon chopped fresh basil leaves, plus sprigs for garnish
• 2 garlic cloves, crushed
• 1 teaspoon salt
• 1/2 teaspoon freshly ground black pepper
• 4 New York strip steaks, 1 1/2 to 2 inches thick
• 4 large portobello mushrooms
• 1 cup dry cabernet sauvignon

Instructions

1. Whisk all the marinade ingredients together in a large bowl. Set aside. Transfer half of the marinade into 1 shallow non-reactive pan or bowl and reserve the other half of the marinade for the mushrooms.
2. Trim excess fat from the steaks and make small cuts with a knife into the fat around the edge of the steaks. Marinate steaks for at least 30 minutes at room temperature, or up to 6 hours in the refrigerator.
3. Preheat a grill to high heat.
4. Place steaks on the hot grill for 3 minutes on each side to sear and create nice grill marks. Reduce the grill temperature to low and close the lid. Continue cooking steaks an additional 5 to 10 minutes for medium-rare, turning them halfway through. Let steaks rest for 5 minutes before serving.
5. Meanwhile, dip the mushrooms in the reserved marinade and place on the grill, curved side down. Put the leftover marinade from the steaks and mushrooms in a small saucepan and bring to a boil for at least 3 minutes and cook until reduced slightly. Lightly coat the serving platter with extra-virgin olive oil and whole leaves of fresh rosemary, oregano, and basil. Transfer the steaks and mushrooms to the platter and drizzle with the sauce.
