Step 1: Build the sauce base - Add the chicken breasts to the bottom of your slow cooker. Pour in the Alfredo sauce and chicken broth, then add the minced garlic, Italian seasoning, and black pepper. Stir gently around the chicken so the sauce is evenly mixed.
Step 2: Slow cook the chicken - Cover and cook on low for 3 to 4 hours. The chicken should be fully cooked and very easy to shred with a fork. Your kitchen will already smell incredible at this point.
Step 3: Shred the chicken - Remove the chicken breasts and place them on a cutting board. Shred them using two forks, then return the chicken to the slow cooker and stir it into the sauce.
Step 4: Add the ravioli - Layer the frozen cheese ravioli on top of the chicken and sauce. Gently press them down so most are covered, but do not stir aggressively.
Step 5: Add the cheese - Sprinkle the mozzarella and Parmesan evenly over the top. This is where the magic happens.
Step 6: Finish cooking - Cover and cook on low for another 30 to 40 minutes, just until the ravioli are tender and the cheese is melted and bubbly.
Step 7: Serve and enjoy - Spoon into bowls and finish with fresh parsley or basil if you like. Then sit down and enjoy a quiet moment before someone asks for seconds.
