01 - In a large bowl, whisk together orange juice, lime juice, olive oil, minced garlic, oregano, cumin, salt, pepper, smoked paprika (if using), and orange zest to make the mojo marinade.
02 - Add chicken thighs to the marinade, turning to coat well. Cover and refrigerate for at least 30 minutes (up to 6 hours for best flavor).
03 - Preheat oven to 425°F. Arrange the chicken thighs skin-side up on a baking sheet or in a large roasting pan. Reserve leftover marinade.
04 - Roast for 30–35 minutes, basting once or twice with the reserved marinade, until chicken is golden brown and cooked through (internal temperature should reach 165°F).
05 - Remove from oven and let rest 5 minutes. Garnish with chopped cilantro or parsley and serve with lime wedges.
