Remove the chicken from the oven after 15-20 minutes.
Top each chicken breast with creamed spinach, chopped bacon, caramelized mushrooms, and a slice of Pepper Jack cheese.
Return to the oven and bake uncovered for another 15-20 minutes until the chicken is thoroughly cooked and cheese has melted.
For a golden-brown top, broil for the last 2-4 minutes, watching closely to avoid burning.
