These grilled BBQ boneless chicken thighs are a staple during the summer months! You'll love how juicy, sweet, tangy, and savory these grilled chicken thighs are! They come together quickly and easily, making them the perfect crowdpleaser or as a weeknight dinner.
Pat dry the chicken thighs with a paper towel if needed and transfer to a large mixing bowl. To a mixing bowl, add the oil, salt, pepper, garlic powder, onion powder, paprika, oregano, ground mustard, and brown sugar. Mix until well-coated.
Heat the grill to 400F.
Place the chicken thighs onto the grill, smooth side down.
Grill the chicken thighs on direct heat for 3 minutes, depending on their size. Keep the grill lid closed.
Open the lid and flip the chicken thighs. Brush the chicken thighs generously with BBQ sauce and close the lid, letting them cook for 3 minutes.
Open the lid and flip the chicken thighs again. Brush the other side, and cook for another minute with the lid closed.
Flip the chicken one last time to let the just-brushed side sear for a minute. Remove the chicken from the grill and rest for at least five minutes before serving. If possible, cover with foil.
