Grilled chicken breasts can be the epitome of boring. Too often they're dried out or rubbery. But when soaked in a super-quick marinade — with balsamic, brown sugar, and dried thyme — you're guaranteed deliciousness.
1In a medium bowl, whisk together balsamic vinegar, olive oil, brown sugar, garlic, and dried herbs, and season generously with salt and pepper. Reserve ¼ cup.
2Add chicken to the bowl and toss to combine. Let marinate at least 20 minutes and up to overnight.
3Preheat grill to medium high. Add chicken and grill, basting with reserved marinade, until cooked through, 6 minutes per side.
