📖 Instructions

1. First, let's get the marinade ready. In a medium bowl, whisk together 1/2 cup of dry white wine (like Sauvignon Blanc or Pinot Grigio), 2 tablespoons of olive oil, 2 cloves of minced garlic, 1 tablespoon of chopped fresh tarragon, 1 tablespoon of Dijon mustard, 1/2 teaspoon of salt, and 1/4 teaspoon of black pepper. Don't skimp on the tarragon – it's the star of the show!
2. Next, place the flank steak (about 1.5 to 2 pounds) in a large resealable bag or a shallow dish. Pour the marinade over the steak, ensuring it's evenly coated. Seal the bag or cover the dish and refrigerate for at least 2 hours, or preferably overnight. The longer it marinates, the more flavorful and tender it will become. I know waiting is hard, but trust me, it's worth it! Maybe watch a movie to pass the time?
3. When you're ready to grill, remove the steak from the refrigerator and let it sit at room temperature for about 20-30 minutes. This will help it cook more evenly. While the steak is resting, preheat your grill to medium-high heat. Make sure the grates are clean and lightly oiled to prevent sticking. No one likes a steak stuck to the grill!
4. Now for the fun part: Grilling! Place the flank steak on the preheated grill and cook for about 4-6 minutes per side for medium-rare, or longer depending on your desired level of doneness. Use a meat thermometer to check the internal temperature. For medium-rare, aim for 130-135°F (54-57°C). Remember, it's always better to undercook it slightly, as it will continue to cook while resting.
5. Once the steak is cooked to your liking, remove it from the grill and place it on a cutting board. Tent it loosely with foil and let it rest for at least 10 minutes. This allows the juices to redistribute, resulting in a more tender and flavorful steak. Don't skip this step – it makes a HUGE difference!
6. Finally, slice the flank steak thinly against the grain. This is crucial for tenderness, as it shortens the muscle fibers. Serve immediately, garnished with a sprig of fresh tarragon, if desired. And maybe a side of grilled veggies or a fresh salad? Your call!
