Step‑by‑Step Instructions for Grilled Flank Steak Caprese
Step 1: Prep the Grill
Preheat your grill to medium-high heat, around 400°F (200°C). This optimal temperature will help create those enticing grill marks while locking in the flavors of the flank steak. Make sure to clean and oil the grates to prevent sticking, ensuring a flawless cooking experience.
Step 2: Marinate the Steak
Season the flank steak generously with salt and pepper, then marinate it with balsamic vinegar in a shallow dish or resealable bag. Allow the steak to soak for at least 30 minutes, but for deeper flavor, marinate it up to overnight. This step will enhance the grilled flank steak caprese’s taste.
Step 3: Grill the Steak
Once marinated, place the flank steak on the grill and cook for 4-6 minutes on each side. Look for a rich, brown crust to form, and use a meat thermometer to check for doneness—medium-rare is ideal at 130-135°F (54-57°C). When cooked to perfection, remove the steak from the grill and let it rest for 5 minutes.
Step 4: Prepare the Balsamic Glaze
While the steak rests, simmer balsamic vinegar with brown sugar in a saucepan over medium heat. Stir frequently as it reduces, cooking for about 10 minutes or until it thickens slightly to a syrupy consistency. This balsamic glaze adds a sweet and tangy essence to your grilled flank steak caprese.
Step 5: Assemble the Caprese
After resting, slice the flank steak against the grain to ensure tenderness. On a serving platter, layer the steak slices with fresh tomatoes, creamy mozzarella, and fragrant basil leaves. Drizzle the balsamic glaze over the top, and enjoy this vibrant grilled flank steak caprese dish that beautifully melds summer flavors.
