In a small mixing bowl, combine 1 1/2 teaspoons salt, 1 teaspoon black pepper, 1 teaspoon smoked paprika, 1 teaspoon dried parsley, 1/2 teaspoon onion powder, and1/2 teaspoon garlic powder.
Pat the 4 medium boneless skinless chicken breast dry with paper towels. Drizzle 1 tablespoon olive oil over the chicken breasts and rub to coat all sides evenly.
Sprinkle the spice mixture evenly over the chicken breasts. Rub the seasoning into the meat to ensure full coverage.
Place the chicken breasts directly on the smoker rack. Close the lid and cook until the internal temperature reaches 145℉ (63℃). This will take approximately 90 minutes, depending on the thickness of the chicken breasts.
Increase the smoker temperature to 400℉ (204℃). Melt 4 tablespoons salted butter and use it to baste the chicken.
Continue to cook until the internal temperature reaches 160℉ (71℃), about 15 to 20 minutes longer.
Remove the chicken from the smoker and allow it to rest for 5 to 10 minutes before serving.
Notes
We recommend using hickory or cherry pellets, or a combination of both when smoking chicken. Feel free to experiment with your own favorites.
