Place the chicken breasts in the bottom of your crockpot and season lightly with salt and pepper.
Add the sliced carrots, diced onion, and minced garlic over the chicken. Pour in the chicken broth and tuck in the bay leaves.
Cover and cook on low for about 6 hours, until the chicken is tender and shreds easily.
Remove the chicken from the crockpot and shred it into bite-sized pieces using two forks. Discard the bay leaves.
Return the shredded chicken to the crockpot and stir it into the flavorful broth with the vegetables.
Turn the crockpot to high, and cook for an additional 2 hours, until the vegetables are tender and the flavors meld together beautifully.
Add the egg noodles directly into the hot broth. Cover and cook on high for 8-10 minutes, until the noodles are al dente and springy.
Taste and adjust seasoning with salt and pepper as needed. Remove the soup from the heat.
Stir in freshly chopped parsley for a bright, fresh flavor. Serve hot, with plenty of noodles, shredded chicken, and vegetables in each bowl.
