These sweet and spicy grilled chicken thighs have become my go-to for summer cookouts and family dinners. The secret lies in the perfect balance of a smoky rub that caramelizes on the grill paired with chicken thighs that stay juicy and tender every time.
I first whipped up this recipe on a whim for a backyard BBQ and everyone was asking for seconds and the recipe by the end of the night.
Ingredients
- Boneless skinless chicken thighs: Essential for juicy results Look for even pieces to ensure even cooking
- Brown sugar: This adds that gorgeous caramelization and balances the heat Choose fine brown sugar that will coat evenly
- Onion powder: Creates aromatic depth Pick a fresh jar for the best flavor
- Chili powder: Adds the classic warmth and a bit of color Try a high quality chili blend
- Smoked paprika: Brings a smoky backnote that tastes like summer every time Spanish smoked paprika gives amazing authenticity
- Granulated garlic or garlic powder: Boosts savory flavor Use a garlic powder with no added salt for better control
- Dried oregano: A touch of herby earthiness Go for dried whole leaf oregano and crush as you add
- Salt: Vital for bringing out flavor in every bite
- Red pepper flakes: Where the heat comes in Adjust based on how spicy you like it and crush slightly for even distribution
Step-by-Step Instructions
- Mix the Rub:
- Combine brown sugar onion powder chili powder smoked paprika granulated garlic dried oregano salt and red pepper flakes in a small bowl until completely uniform using a fork to break up any clumps
- Coat the Chicken:

- Marinate for Flavor:
- Cover the bowl or seal the bag and refrigerate for at least four hours For the deepest flavor marinate overnight You want to let the spices soak in
- Grill to Perfection:

- Rest and Serve:
- Transfer the chicken to a platter and let it rest for five minutes This locks in the juices and keeps every bite tender and flavorful

Smoked paprika is my favorite part of this rub Every time I open the jar it brings back memories of grilling as a kid with my family at the lake I love the way it perfumes the air while the chicken is on the grill
