Step 1: Season the Chicken - Start by seasoning the chicken breasts on both sides with salt and black pepper. This is a small step, but it makes a big difference in flavor later.
Step 2: Bread the Chicken - Set up your breading station with flour, beaten eggs, and a mixture of breadcrumbs and grated Parmesan. Dredge each chicken breast in flour, dip it into the eggs, then coat it generously with the breadcrumb mixture. Press gently so everything sticks.
Step 3: Brown the Chicken - Heat the oil in a skillet over medium high heat. Brown the chicken on both sides for about two minutes per side. You are not cooking it through, just creating a golden crust that adds flavor and texture.
Step 4: Mix the Sauce - In a large bowl, combine the red pasta sauce, tomato sauce, Italian seasoning, and minced garlic. Stir until everything is well blended.
Step 5: Layer the Slow Cooker - Spread half of the sauce mixture in the bottom of the slow cooker. This prevents sticking and keeps the coating from getting soggy.
Step 6: Add the Chicken - Place the browned chicken breasts on top of the sauce, then pour the remaining sauce over them. Sprinkle the additional Italian seasoning on top.
Step 7: Slow Cook - Cover and cook on low for four hours, or until the chicken is cooked through and tender.
Step 8: Add the Cheese - During the last fifteen minutes of cooking, sprinkle the mozzarella cheese over the chicken. Cover again and let it melt into a bubbly, cheesy layer.
Step 9: Serve and Garnish - Serve the chicken over cooked spaghetti and finish with fresh parsley and basil.
