Ingredients

For the Flank Steak:

• 1.5 to 2 lbs flank steak
• 2 tablespoons olive oil
• 1 teaspoon kosher salt
• 1/2 teaspoon black pepper

For the Marinade:

• 1/4 cup soy sauce (or tamari for gluten-free)
• 2 tablespoons olive oil
• 2 tablespoons balsamic vinegar
• 1 tablespoon Worcestershire sauce
• 3 cloves garlic, minced
• 1 teaspoon dried oregano
• 1/2 teaspoon red pepper flakes (optional, for a little heat)

How to Make It

1. Prepare the Marinade:

1. In a medium bowl, whisk together the soy sauce, olive oil, balsamic vinegar, Worcestershire sauce, minced garlic, dried oregano, and red pepper flakes (if using).

2. Marinate the Flank Steak:

1. Place the flank steak in a large resealable plastic bag or a shallow dish.
2. Pour the marinade over the steak, ensuring it’s evenly coated.
3. Seal the bag or cover the dish and refrigerate for at least 30 minutes, or up to 4 hours for deeper flavor.

3. Preheat the Oven and Pan:

1. Preheat your oven to 400°F (200°C).
2. While the oven preheats, place an oven-safe skillet (cast iron works wonderfully) over medium-high heat on the stovetop. Add the 2 tablespoons of olive oil to the hot skillet.

4. Sear the Steak:

1. Remove the flank steak from the marinade, letting any excess drip off. Discard the remaining marinade.
2. Season the steak generously with kosher salt and black pepper on both sides.
3. Carefully place the seasoned flank steak into the hot, oiled skillet. Sear for 2-3 minutes per side until a beautiful brown crust forms. This step is crucial for developing flavor and a lovely texture.

5. Roast in the Oven:

1. Transfer the oven-safe skillet with the seared flank steak directly into the preheated oven.
2. Roast for 8-12 minutes for medium-rare (internal temperature of 130-135°F or 54-57°C), or 12-15 minutes for medium (140-145°F or 60-63°C). The exact time will depend on the thickness of your steak and your oven. Use a meat thermometer for best results.

6. Rest and Slice:

1. Once cooked to your desired doneness, remove the skillet from the oven.
2. Transfer the flank steak to a cutting board and let it rest for at least 10 minutes. This resting period is vital for allowing the juices to redistribute throughout the meat, ensuring a tender and moist steak.
3. To serve, slice the flank steak thinly against the grain. You’ll see the direction of the muscle fibers; slice across them for optimum tenderness.

Tips for Success

Marinating Magic:

The marinade not only adds flavor but also tenderizes the meat. For flank steak, a shorter marinating time (30 minutes to 2 hours) is often sufficient. Prolonged marination, especially with acidic ingredients, could potentially break down the meat too much. If you’re short on time, even 15 minutes will impart some nice flavor.

Achieving the Sear:

A hot pan is key to getting that desirable crust. Make sure your skillet is properly preheated before adding the steak. The sizzle should be immediate and robust. Don’t overcrowd the pan if you’re cooking multiple steaks; sear them in batches if necessary.

Temperature is Key:

Flank steak is best enjoyed cooked to medium-rare or medium. Overcooking will result in a tougher, drier steak. Invest in an instant-read meat thermometer to ensure perfection. Remember the temperature will rise a few degrees as it rests.

Serving Ideas

This oven-roasted flank steak is remarkably versatile and pairs beautifully with a variety of dishes. Serve it sliced thinly over a vibrant salad with a Caesar or vinaigrette dressing. Transform it into mouthwatering fajitas by serving with sautéed bell peppers and onions, tortillas, and your favorite toppings like salsa, guacamole, and sour cream.

It’s also fantastic in steak sandwiches, nestled into a baguette with caramelized onions and provolone cheese, or simply served as a main course with classic sides such as roasted potatoes, mashed sweet potatoes, or steamed asparagus. The possibilities are truly endless!
