In a second shallow bowl, combine bread crumbs and parmesan cheese.
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.
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.
Garnish with fresh chopped parsley and basil and serve.
Notes
Any type of breadcrumbs will work - the Italian seasoned breadcrumbs have lots of flavor added in, making this super easy to bread and season the chicken at once. You can also use panko or plain breadcrumbs and add your own seasonings.
You can use any combo of Italian cheeses to top the chicken.
Store in an airtight container in the refrigerator for 3-4 days, or cool the meal and freeze for up to 3 months.
