Preheat the broiler. Line a baking pan with foil or parchment paper and spray with nonstick cooking spray.
In a small bowl, combine the brown sugar, lemon pepper, garlic powder, salt, and cayenne. Add the melted butter and stir to combine.
Brush the chicken with the butter mixture. Broil for about 5 minutes until the top is starting to turn golden brown, then flip the chicken and broil the other side for 5 minutes, until the top is golden brown and the chicken is cooked through.
Let the chicken sit for a couple of minutes, then slice and serve.
Notes
This recipe is for boneless, skinless chicken breasts, but you can definitely use it on skin-on, bone-in pieces of chicken. Roast bone-in chicken instead of broiling it to avoid burning it. Bone-in chicken breasts or thighs will take about 40 minutes in a 400-degree oven, depending on their size.
You can also cook these chicken breasts in an air fryer. Preheat the air fryer to 350 degrees and cook them for 10 to 12 minutes, until the chicken is cooked through (165°F internal temperature). You can follow the instructions for Lemon Garlic Air Fryer Chicken Breasts.
Line the pan with oil or parchment paper before adding the chicken for easy cleanup.
