1️⃣ Prepare the Garlic and Rosemary: Mince the garlic cloves and rosemary sprigs to make the marinade.

2️⃣ Mix the Marinade: In a bowl, combine ⅓ cup of balsamic vinegar, 2 tablespoons of soy sauce, ⅔ cup of brown sugar, and 2 tablespoons of olive oil. Stir to combine.

3️⃣ Add Seasonings: Add the minced rosemary, garlic, kosher salt, ground black pepper, and red pepper into the mixture and mix well.

4️⃣ Marinate the Steak: Pour the marinade into a zip-lock bag and shake well to combine. Add the steak to the bag, making sure it’s fully coated. Refrigerate for at least 6 hours, or overnight for even more flavor.

5️⃣ Prepare the Steak for Cooking: Once marinated, remove the steak from the bag, pat it dry with paper towels, and set it aside to come to room temperature.

6️⃣ Cook the Steak: Heat 1 tablespoon of olive oil in a skillet over medium-high heat. Once hot, add the steak to the skillet and cook to your desired level of doneness, searing it until crispy on both sides.
