Grilled Flank Steak with Mushrooms

Ingredients

For the Steak:

  • 1 ½ – 2 lbs flank steak

  • 3 tbsp olive oil

  • 3 cloves garlic, minced

  • 2 tbsp soy sauce

  • 2 tbsp Worcestershire sauce

  • 2 tbsp balsamic vinegar

  • 1 tsp Dijon mustard

  • 1 tsp fresh rosemary or thyme (optional)

  • Salt & freshly cracked black pepper

For the Mushrooms:

  • 1 lb cremini or button mushrooms, halved or thickly sliced

  • 2 tbsp olive oil

  • 3 tbsp butter

  • 3 cloves garlic, minced

  • 1 tbsp fresh parsley, chopped

  • Salt & pepper, to taste


Instructions

  1. Marinate the Flank Steak:

    • In a bowl, whisk together olive oil, garlic, soy sauce, Worcestershire, balsamic vinegar, Dijon mustard, and herbs.

    • Place flank steak in a resealable bag or shallow dish, pour marinade over, and refrigerate for at least 2 hours (overnight for best flavor).

  2. Prepare the Mushrooms:

    • Heat olive oil and butter in a skillet over medium heat.

    • Add garlic and cook for 30 seconds until fragrant.

    • Toss in mushrooms, season with salt and pepper, and sauté until golden brown and tender (about 8–10 minutes).

    • Stir in parsley and set aside.

  3. Grill the Steak:

    • Preheat grill to medium-high heat.

    • Remove steak from marinade and pat dry (to help it sear).

    • Grill flank steak for 4–6 minutes per side for medium-rare (depending on thickness).

    • Let steak rest 5–10 minutes, then slice thinly against the grain.

  4. Serve:

    • Arrange steak slices on a platter and spoon the garlicky mushrooms over the top.

    • Optional: drizzle with pan juices or a touch of balsamic glaze.
