Sprinkle chicken breasts with salt and pepper.

In a shallow bowl, whisk together egg and milk.

In a second shallow bowl, combine bread crumbs and parmesan cheese.

Step 4

Dip each chicken breast into the egg mixture and then into the bread crumb mixture, coating both sides well.

Spread ½ cup marinara sauce in the bottom of the slow cooker. Place coated chicken breasts in a single layer over the sauce.Sprinkle 1 cup of mozzarella cheese evenly over the chicken, then pour the remaining sauce over the top.

Step 6

Cover the crockpot and cook on LOW for 5 hours. Confirm that the chicken is cooked through by inserting a cooking thermometer into the thickest portion of chicken. The internal temperature should be 165°F.

Once the chicken is cooked, sprinkle the remaining mozzarella cheese over everything. Cover, and continue cooking for about 15 minutes longer, or until the cheese melts.
