This creamy and delicious pasta dish is made even easier with a slow cooker. Add chicken breasts, Alfredo sauce, chicken broth, and garlic to your crockpot. Cook on low for 6-8 hours, then add cooked pasta and Parmesan cheese to the mixture. Cook for an additional 30 minutes until the pasta is heated through. It's a comforting and satisfying meal that's perfect for a cozy night in.
