How to Make The Best Grilled Chicken Fillet
Step 1: Pound the Chicken
Place chicken breasts between two sheets of plastic wrap or inside a zip-top bag. Use a meat mallet to pound them to an even thickness. This ensures they cook uniformly.
Step 2: Make the Marinade
In a resealable bag or shallow bowl, whisk together the balsamic vinegar, lemon juice, olive oil, garlic, rosemary, basil, salt, and pepper until well combined.

Add the chicken to the marinade and coat thoroughly. Seal the bag or cover the bowl and refrigerate for at least 30 minutes but not more than four hours. Before grilling, let the chicken sit at room temperature for about 20 minutes.
Step 4: Preheat the Grill
Heat your grill or grill pan to medium-high (375–450°F). Lightly oil the grates or pan to prevent sticking.
