Set your oven temperature to 375°F to get it ready.
Combine the BBQ sauce and ranch dressing together in a small bowl until smooth.
Dry the chicken breasts with paper towels and arrange them on a baking sheet lined with parchment paper or aluminum foil.
Coat each chicken breast generously with the ranch and BBQ sauce mixture on one side.
Turn the chicken over and cover the opposite side with the remaining sauce.
Place the tray in the oven and bake the chicken for 25 to 45 minutes, or until fully cooked and juices run clear.
Take the chicken out and serve hot alongside your favorite roasted veggies, potatoes, or corn muffins for a complete meal.
