Trim any excess fat from the chicken thighs and place in a large bowl.
Season the chicken with salt, pepper, paprika, Aleppo pepper/chili flakes, garlic powder, chipotle powder, coriander, and cayenne pepper.
Add the fresh cilantro, olive oil, yogurt, and lime juice, and mix well.
Thinly slice the red onion and mix it into the chicken.
Marinate the chicken for 2-4 hours if possible.
Preheat the oven to 425°F.
Pack the marinated chicken tightly into a loaf pan and bake for 50-55 minutes.
Remove the chicken from the oven, tilt the pan to pour out the excess juices, and then flip the pan over a cutting board to cut the chicken into strips or cubes.
Serve the chicken however you like, such as in a high protein bowl with low-carb rice, baby kale, avocado, and a garlic white sauce.
