📝 Instructions

9 steps
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.

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.

3

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

4

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

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.

6

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

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.

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.

9

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