Ingredients

• 2 pounds flank steak
• 3 tablespoons Dijon mustard
• 2 teaspoons whole black peppercorns
• 4 cloves garlic cloves
• 2 tablespoons olive oil
• 2 tablespoons soy sauce
• 1 tablespoon red wine vinegar
• 1 teaspoon salt
• 2 tablespoons fresh parsley (optional, for garnish)

Directions

Step 1

Place the flank steak in a large resealable plastic bag or a shallow baking dish.

Step 2

Crush the peppercorns with a mortar and pestle or the bottom of a heavy skillet, ensuring they remain coarse for maximum flavor.

Step 3

In a small bowl, whisk together Dijon mustard, crushed peppercorns, minced garlic, olive oil, soy sauce, red wine vinegar, and salt until well combined.

Step 4

Pour the marinade over the flank steak, ensuring it is evenly coated. Seal the bag or cover the dish and refrigerate for at least 2 hours, preferably overnight for best flavor.

Step 5

When ready to cook, remove the steak from the refrigerator and let it come to room temperature for about 30 minutes.

Step 6

Preheat a grill or grill pan over medium-high heat. Lightly oil the grates to prevent sticking.

Step 7

Remove the steak from the marinade, allowing excess to drip off. Grill the steak for 5-6 minutes per side for medium-rare, or adjust cooking time to your desired doneness.

Step 8

Transfer the cooked steak to a cutting board and allow it to rest for 10 minutes to retain its juices.

Step 9

Slice the steak thinly against the grain for maximum tenderness.

Step 10

Garnish with freshly chopped parsley, if desired, and serve immediately. Pair with a side of roasted vegetables or a crisp green salad for a complete meal.
