Crock Pot Chicken Parmesan is a simple gluten free dinner that's perfect for a weeknight. Just set the chicken and marinara sauce in the slow cooker and forget about it, then add cheese and pasta just before serving. It's minimal effort, with a ton of flavor!
Place chicken breast, marinara sauce, garlic, salt, and pepper into slow cooker. Cover and cook on HIGH 4 hours, or on LOW 8 hours.
Once chicken is done, remove and cut into 1-inch pieces. Add back to slow cooker.
Cook gluten free penne until al dente. Once done, drain and add to slow cooker.
Add 1 cup mozzarella and 1 cup parmesan over pasta, then stir everything together. Top with remaining 1 cup mozzarella and place the lid back onto the slow cooker (use the WARM setting if you have it).
Once cheese on top is melted, serve.
