Step 1

In a mixing bowl, combine the olive oil, Worcestershire sauce, minced garlic, black pepper, and Italian seasoning.

Step 2

Place the flank steak in a resealable bag or a shallow dish, and then pour the marinade over the steak.

Step 3

Seal the bag or cover the dish with plastic wrap and refrigerate for at least 2 hours.

Step 4

When you're ready to cook, remove the marinated steak from the fridge and let it sit at room temperature for about 30 minutes.

Step 5

Preheat your oven to 350 degrees F (175°C).

Step 6

Place a cast iron skillet or pan on the stovetop and heat it over medium-high heat.

Step 7

Add a bit of oil to the skillet and sear the steak for about 2-3 minutes on each side until a beautiful crust forms.

Step 8

Transfer the skillet with the steak to the preheated oven and continue to cook it for 10-15 minutes more or until it reaches your preferred level of doneness.

Step 9

After your steak reaches your desired temperature, remove it from the oven and let it rest for about 5-10 minutes.

Step 10

Place your rested steak on a cutting board and, using a sharp knife, slice it against the grain into thin slices and serve.

Step 11

Garnish with fresh parsley and serve your juicy London broil with your favorite side dishes and sauces, and add kosher salt, if you like, to taste.
