1. In a bowl, combine the minced garlic, minced rosemary, balsamic vinegar, soy sauce, dark brown sugar, 2 tablespoons of olive oil, kosher salt, ground black pepper, and red pepper. Mix well to create the marinade.

2. Place the steak in a zip-lock bag and pour the marinade over it. Seal the bag and shake well to ensure the steak is coated evenly. Place the bag in the refrigerator and let the steak marinate for at least 6 hours, or overnight for even better flavor.

3. After marinating, remove the steak from the bag and pat it dry with a paper towel. Discard the marinade.

4. In a skillet, heat 1 tablespoon of olive oil over medium-high heat. Once hot, add the steak to the skillet and cook to your preferred level of doneness, about 5-7 minutes per side for medium-rare, depending on the thickness of the steak. Adjust cooking time accordingly for your desired level of doneness.

5. Once cooked, remove the steak from the skillet and let it rest for a few minutes before slicing.

6. Slice the steak against the grain into thin slices.

7. Serve the deliciously marinated steak hot and enjoy!
