Make the Marinade
In a large bowl, whisk together olive oil, lemon juice, soy sauce, garlic, paprika, oregano, cumin, salt, and pepper.
Marinate the Chicken
Add the cubed chicken to the marinade and toss to coat well. Cover and marinate for at least 30 minutes (up to 4 hours) in the refrigerator.
Preheat the Oven
Preheat your oven to 425°F (220°C). Line a baking sheet with foil and place a wire rack on top, or use a broiler pan.
Assemble the Skewers
Thread the marinated chicken pieces onto skewers, leaving a little space between each for even cooking.
Bake the Skewers
Arrange the skewers on the wire rack. Bake for 20–25 minutes, turning halfway through, until chicken is golden brown and cooked through (internal temp: 165°F/74°C).
Optional Broil Finish
For a crispier exterior, broil the skewers on high for 2–3 minutes at the end.
Serve
Serve hot with rice, salad, pita, or your favorite dipping sauces.
