Step-by-Step Instructions for Perfect Grilled Flank Steak

1. Prepare the Marinade

• In a large freezer-safe ziplock bag, whisk together all marinade ingredients.

• Remove 2 tbsp and set aside for later.

• Add the flank steak to the bag, press out excess air, and seal.

• Massage the marinade into the steak through the bag for even coating.

2. Marinate the Steak

• Refrigerate for at least 2 hours, but ideally up to 12 hours for maximum flavor and tenderness.

• Pro Tip: Don’t marinate longer than 12 hours, as the meat can become mushy.

3. Preheat the Grill

• Heat your grill to medium-high (450°F) for perfect searing.

• Clean & grease the grill grates well to prevent sticking.

4. Grill the Flank Steak

• Remove steak from the fridge and let it sit at room temperature for 30-60 minutes before grilling.

• Place steak on the grill and cook for 5-6 minutes per side (for medium-rare to medium).

• Use a meat thermometer for accuracy:

  • Medium-rare: 130-135°F

  • Medium: 140°F (recommended)

  • Medium-well: 150°F

5. Rest & Slice

• Transfer steak to a cutting board and let it rest for 10 minutes to retain juices.

• Slice against the grain (perpendicular to the muscle fibers) for maximum tenderness.

• Drizzle with the reserved marinade for extra flavor.

The Best Marinade for Easy Grilled Flank Steak

One of the keys to making perfectly tender and flavorful easy grilled flank steak is the marinade. A good marinade not only enhances taste but also helps break down the muscle fibers, making the steak more tender.

Why This Marinade Works So Well

Flank steak is a lean, fibrous cut, which means it benefits greatly from marinating. The combination of acid (balsamic vinegar and lemon juice), salt (soy sauce), and sweetness (brown sugar) in this marinade helps:

• Tenderize the meat (acids break down tough fibers).

• Infuse deep flavor (herbs and spices penetrate the steak).

• Keep the steak juicy (oil and Worcestershire sauce add moisture).

Key Ingredients & Their Roles

1. Olive Oil – Helps distribute flavors and keeps the steak moist.

2. Soy Sauce – Adds umami and saltiness.

3. Balsamic Vinegar – Provides tangy sweetness and tenderizes.

4. Lemon Juice – Brightens flavors and aids in tenderizing.

5. Brown Sugar – Balances acidity and promotes caramelization.

6. Worcestershire Sauce – Deepens savory notes.

7. Dijon Mustard – Adds a slight sharpness and helps emulsify the marinade.

8. Spices (Garlic Powder, Onion Powder, Paprika, etc.) – Build layers of flavor.

Marinating Tips for Maximum Flavor

• Marinate for at least 2 hours, but up to 12 hours for best results.

• Don’t over-marinate (beyond 12 hours) or the meat can become mushy.

• Massage the marinade into the steak to ensure even coating.

• Use a ziplock bag for easy cleanup and even marinating.

Can You Reuse the Marinade?

No! Because the marinade has been in contact with raw meat, it should never be reused as a sauce. If you want extra marinade for serving, set aside a portion before adding the steak.

How to Grill Flank Steak Perfectly Every Time

Grilling flank steak is quick and easy, but a few key steps ensure juicy, tender results every time.

Prepping the Steak for the Grill

1. Let it come to room temp – Take the steak out of the fridge 30-60 minutes before grilling for even cooking.

2. Pat it dry – Excess moisture prevents a good sear.

3. Oil the grill grates – Prevents sticking and helps with grill marks.

Grilling Temperature & Time

• Preheat grill to medium-high (450°F) for a perfect sear.

• Grill for 5-6 minutes per side (for medium-rare to medium).

• Use a meat thermometer for accuracy:

  • Rare: 125°F

  • Medium-rare: 135°F

  • Medium: 140°F (recommended)

  • Medium-well: 150°F

Common Grilling Mistakes to Avoid

❌ Flipping too often – Only flip once for a good crust.
❌ Using a fork to flip – Piercing the steak releases juices.
❌ Overcooking – Flank steak is best at medium-rare to medium.
❌ Skipping the rest time – Letting it rest 10 minutes keeps it juicy.

How to Get Perfect Grill Marks

• Place steak on the grill at a 45° angle for 2-3 minutes.

• Rotate 90° (without flipping) for crosshatch marks.

• Flip and repeat.

Alternative Cooking Methods

• Oven (Broiler): 6-8 minutes per side.

• Stovetop (Cast Iron): 6-8 minutes per side in a hot skillet.
