Preheat your oven to 400°F (200°C).
Place the chicken breast between two sheets of plastic wrap or parchment paper. Use a meat mallet or rolling pin to pound the chicken to an even thickness of about 1/2 inch.
In a mixing bowl, pour the milk. In another bowl, combine the panko breadcrumbs, salt, and pepper. Mix well.
Dip the chicken breast into the milk, then coat it in the panko mixture. Place in a baking dish.
Bake the chicken for about 20 minutes, or until cooked through and the internal temperature reaches 165°F (75°C).
While the chicken is baking, bring a small saucepan of salted water to a boil and cook the fettuccine noodles according to package instructions. Drain and set aside.
Once the chicken is done baking, pour the red sauce over the chicken and sprinkle the cheeses on top.
Return the baking dish to the oven and bake for an additional 10 minutes, until the cheese is melted and bubbly.
Serve the chicken over the cooked fettuccine noodles, spooning extra red sauce over if desired.
