Preheat the oven to 375°F and line a baking sheet with parchment paper. Set aside. Season chicken breasts with salt and pepper and set aside.
Prepare two bowls - larger bowl and shallow one (or a plate). In a larger bowl, add the ranch dressing.
In a shallow bowl or plate, place the bread crumbs.
Dip each breast in the ranch dressing, turning on all sides until well-coated, shaking off any excess dressing.
Next transfer the chicken to the bread crumbs bowl and turn until evenly coated.
Arrange the coated chicken on a parchment–lined baking sheet. Bake for 30 minutes at 375 F, until an internal temperature of 165°F or until juices run clear.
