Gather the ingredients. Tip: Let chicken rest at room temperature for 10 minutes so it cooks evenly.

In a bowl, whisk together lemon juice, olive oil, garlic, oregano, salt, and pepper until combined.

Place chicken in a resealable plastic bag or shallow dish and pour marinade over the top. Seal and refrigerate for 30 minutes (up to 2 hours for deeper flavor).

Preheat grill to medium-high heat (around 400°F). Brush grates with oil to prevent sticking.

Remove chicken from marinade, shaking off excess. Grill each breast for about 6–7 minutes per side, or until the internal temperature reaches 165°F.

Transfer chicken to a plate, cover loosely with foil, and let rest for 5 minutes before slicing. This locks in the juices for maximum tenderness.

Serve with fresh lemon wedges, a green salad, or your favorite side dishes. Enjoy!
