To make these grilled spicy coconut chicken thighs, you'll need to first make the marinade. Add the coconut milk, olive oil, sambal oelek, ginger, garlic, coconut sugar, lime juice, and salt to a blender. Blend until the mixture is completely smooth.
Next, pat the chicken thighs dry with a paper towel.
Place them in a large bowl and pour about ¾ of the marinade over the top. Toss well so every piece is coated. Cover the bowl and let the chicken marinate in the fridge for at least 30 minutes. Be sure to save the remaining sauce; you'll use it later for dipping.
Preheat your grill to 450F. Spray the grill grates with avocado oil spray to prevent sticking.
Now, it's time to grill! Place the chicken thighs directly onto the hot grill and let them cook undisturbed for 7 minutes.
Flip each thigh and cook for another 6-7 minutes, or until the temperature reaches 165F.
Once cooked, remove the chicken from the grill and let it rest for 5 minutes.
Finally, garnish the chicken with chopped cilantro and lime wedges.
Serve with the reserved dipping sauce and chili crisp for extra heat, if desired. Enjoy!
