Ingredients:
- 1/2 cup balsamic vinegar
- 1/4 cup extra virgin olive oil
- 2 tbsp honey
- 3 cloves garlic, minced
- 1 tbsp Dijon mustard
- 1 tsp dried oregano
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 2 lbs flank steak
Instructions:
- In a small bowl, whisk together the balsamic vinegar, olive oil, honey, garlic, mustard, oregano, salt, and pepper until emulsified.
- Place the flank steak into a gallon-sized Ziploc bag, pour the marinade over the meat, seal, and massage to remove air pockets.
- Refrigerate the steak in the marinade for at least 4 hours, up to 24 hours.
- Remove the steak from the refrigerator 30 minutes before cooking to bring it to room temperature.
- Preheat a grill or cast iron skillet to medium-high heat.
- Remove steak from the marinade, discard the used liquid, and sear for 4–6 minutes per side.
- Use a meat thermometer to remove the steak from heat when it reaches an internal temperature of 130°F (54°C) for medium-rare.
- Transfer the steak to a cutting board and let it rest before slicing against the grain.
