In a medium bowl, whisk together lime juice, lime zest, chopped cilantro, minced garlic, olive oil, cumin, salt, and pepper.
Place chicken thighs in a large resealable bag or shallow dish and pour the marinade over them, ensuring even coating.
Marinate the chicken in the refrigerator for at least 30 minutes or up to 4 hours.
Heat a large skillet over medium-high heat with a drizzle of oil.
Remove chicken from marinade and sear for 5-7 minutes per side until the internal temperature reaches 165 degrees Fahrenheit.
Remove from heat and let rest for 5 minutes before serving or portioning for meal prep.
