Flank Steak with Shiitake Mushroom Sauce
  • Steak:
  • teaspoon salt
  • teaspoon black pepper
  • (1-pound) flank steak, trimmed
  • Olive oil
  • Sauce:
  • 1 tbsp butter
  • 1/2 cup chopped onion
  • garlic cloves, minced
  • 1/2 pound mushrooms, sliced (I like crimini)
  • sprig of fresh thyme, or pinch of dry
  • cup beef broth
  • cup sherry
  • tablespoon balsamic vinegar
  • salt and pepper
  • (original recipe calls for green onions to be added in at the last minute but I don't like green onions
  1. Preheat broiler.
  2. To prepare steak, rub with olive oil and sprinkle salt and pepper evenly over both sides of steak. Place steak on a broiler pan; broil 5 minutes on each side or until desired degree of doneness. Remove the steak from oven; loosely cover with foil.
  3. To prepare sauce, heat a large nonstick skillet over medium-high heat. Melt butter in skillet. Add onion and a little salt; sauté 2 minutes.
  4. Add mushrooms, garlic and thyme; sauté for 4 minutes. Add a little more salt to draw out juices.
  5. Add broth, sherry, and vinegar. Bring to a boil and cook until reduced to 3/4 cup (about 8 minutes). Season to taste with salt and pepper.
  6. Slice steak diagonally across the grain into 1/4-inch slices. Serve steak with mushroom sauce
