Grilled Flank Steak with Charred Onion Relish

By lorik

Spearing the onion rounds with a metal or soaked wooden skewer helps them stay together on the grill.

Ingredients

• 1 flank steak (about 1 1/2 pounds)
• Salt and pepper
• 1 red onion, peeled and cut into 1/2-inch rounds (see note)
• 2 tablespoons vegetable oil
• 1/4 cup red wine vinegar
• 1/8 teaspoon cayenne pepper
• 3 tablespoons brown sugar
• 1 tablespoon chopped fresh parsley

Preparation

Step 1

1. Pat steak dry with paper towels and season with salt and pepper. Brush onion rounds with 1 tablespoon oil and season with salt. Grill steak over hot fire until well browned and cooked to desired doneness, about 5 minutes per side for medium-rare. Grill onion until charred and soft, about 5 minutes per side. Transfer steak and onion to cutting board and tent with foil.

2. When cool enough to handle, chop onion coarsely. Heat remaining oil in small saucepan over medium heat until shimmering. Add onion, vinegar, sugar, cayenne, and any accumulated beef juices and simmer until thickened, 3 to 5 minutes. Off heat, stir in parsley. Slice steak thinly against grain. Serve steak with relish.
