- 1/4 cup extra-virgin olive oil
- 1/4 cup balsamic vinegar
- 2 cloves garlic, minced
- 1 tablespoon Italian seasoning
- 1 teaspoon salt
- 1/2 teaspoon freshly ground pepper
1-1 1/4 pounds boneless, skinless chicken breast, (see Note)
Whisk oil, vinegar, garlic, Italian seasoning, salt and pepper in a bowl until well combined.
Place chicken in a shallow dish or 1-gallon sealable plastic bag. Add the marinade and refrigerate for at least 1 hour and up to 12 hours. Remove from the marinade and pat dry.
Preheat grill to medium-high or position a rack in upper third of oven and preheat broiler.
To grill: Oil the grill rack (see Tip). Grill the chicken, turning once, until an instant-read thermometer inserted into the thickest part registers 165°F, 4 to 8 minutes per side.
To broil: Line a broiler pan (or baking sheet) with foil and coat with cooking spray. Place the chicken on the foil. Broil, watching carefully and turning at least once, until an instant-read thermometer inserted into the thickest part registers 165°F, 10 to 15 minutes total.
