Toss in the chicken, carrots, celery, onion, garlic, and roasted red peppers. It's like a little veggie party in there!
Pour in the chicken broth and sprinkle in the Italian seasoning, salt, and pepper. Give it a quick stir. No need for a workout here; we're making soup, not butter.
Cover and let your slow cooker work its magic. Cook on LOW for 6-7 hours or HIGH for 3-4 hours. This is the perfect time to binge-watch that show everyone's been talking about.
Once time's up, carefully remove the chicken and shred it using two forks. It should be so tender it practically falls apart on its own.
Return the shredded chicken to the slow cooker. Now for the good part - stir in the heavy cream and Parmesan cheese. This is what takes this soup from "Meh" to "Marry me!"
Add the egg noodles and cook for another 30 minutes on HIGH until they're tender but still have a bit of bite. Nobody likes mushy noodles, am I right?
Stir in the fresh parsley, taste, and adjust seasoning if needed. You're the boss, applesauce!
