Ingredients

• 1.5 pounds Flank steak
• 0.5 cups Soy sauce
• 0.25 cups Olive oil
• 2 tablespoons Lemon juice
• 3 cloves Garlic, minced
• 1 tablespoon Brown sugar
• 1 teaspoon Ground black pepper
• 2 tablespoons Dijon mustard
• 0.5 cups Heavy cream
• 2 tablespoons Unsalted butter
• 1 teaspoon Salt
• 2 tablespoons Fresh parsley (optional, for garnish)

Directions

Step 1

In a medium bowl, whisk together soy sauce, olive oil, lemon juice, minced garlic, brown sugar, and ground black pepper to make the marinade.

Step 2

Place the flank steak in a large resealable plastic bag or shallow dish, and pour the marinade over it. Seal the bag or cover the dish with plastic wrap. Refrigerate for at least 2 hours or up to 12 hours.

Step 3

Remove the steak from the refrigerator about 30 minutes before cooking to bring it to room temperature. Discard the marinade.

Step 4

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

Step 5

Grill the flank steak for about 5-6 minutes per side for medium-rare, or adjust the cooking time depending on your desired doneness. Use a meat thermometer to ensure an internal temperature of 130°F for medium-rare.

Step 6

Transfer the steak to a cutting board, tent it with foil, and let it rest for 10 minutes before slicing.

Step 7

While the steak is resting, prepare the mustard sauce. In a small saucepan, melt the butter over medium heat. Stir in the Dijon mustard and heavy cream. Cook for 2-3 minutes, stirring constantly, until the sauce thickens slightly. Season with salt to taste.

Step 8

Slice the rested flank steak thinly against the grain and transfer to a serving platter. Drizzle the mustard sauce over the top or serve it on the side.

Step 9

Garnish with chopped fresh parsley, if desired, and serve immediately.
