Start by adding the lime juice and zest, olive oil, chipotle peppers, garlic, cumin, salt, pepper, and sweetener into your blender. Blend everything until smooth. The marinade should be thick and fragrant — I could already smell the magic happening at this point.
Pat your chicken thighs dry, then place them in a glass dish. Pour about two-thirds of the marinade over the chicken, turning each piece to coat it completely. Cover and refrigerate for at least 1 hour (up to 3 for deeper flavor). The longer it sits, the more intense the taste becomes.
Preheat your grill and create two heat zones — direct and indirect. I started the chicken skin-side down over direct heat to get that char. It only needs about 4–5 minutes on each side before moving it to indirect heat.
Move the chicken to indirect heat and brush the tops with the leftover marinade. Let it cook through until it hits an internal temp of 165°F. It took me about 10 more minutes, and I basted it once more for a bigger flavor punch.
Once done, remove the chicken from the grill and let it rest for a few minutes. This locks in all the juices. Then slice or serve whole — either way, it’ll be juicy and packed with flavor.
