8 Servings
Ingredients
- 3 tablespoons soy sauce
- 1 tablespoon ketchup
- 1 tablespoon vegetable oil
- 1 clove garlic minced
- 1 teaspoon salt
- ½ teaspoon ground black pepper
- ½ teaspoon dried oregano
- 4 pounds flank steak
Instructions
Prepare the Marinade
- In a small mixing bowl, combine the soy sauce, ketchup, vegetable oil, minced garlic, salt, pepper, and oregano. Stir the mixture until thoroughly blended.
Score the Steak
- Place the flank steak on a clean cutting board. Using a sharp knife, score both sides of the steak in a diamond pattern, ensuring the cuts are approximately 1/8 inch deep. This step enhances flavor absorption during marination.
Marinate the Steak
- Transfer the steak to a resealable plastic bag or a covered dish. Pour the prepared marinade over the steak, ensuring it is evenly coated. Refrigerate for a minimum of 5 hours, flipping the steak occasionally to ensure even marination. For optimal flavor, marinate overnight.
Preheat the Grill
- Heat an outdoor grill to high heat. Lightly oil the grates to prevent sticking.
Grill the Steak
- Remove the steak from the marinade and discard any excess liquid. Place the steak directly on the preheated grill. Cook for 3 to 7 minutes per side, depending on the desired level of doneness. Use a meat thermometer to ensure accurate cooking (130-135°F for medium-rare, 140-145°F for medium).
Rest and Slice
- After grilling, allow the steak to rest for 5 to 10 minutes. This resting period retains the juices, ensuring tender slices. To serve, slice the steak thinly against the grain to maximize tenderness.
