Sprinkle pepper over chicken breasts and place in the bottom of the slow cooker.
Add celery, onions, carrots, minced garlic, rosemary, thyme, bay leaves, and chicken broth.
Cook on HIGH for 3 hours.
Remove chicken breasts from the soup and shred meat (or cut into chunks).
Return the chicken to the soup and add egg noodles. Continue cooking 20-30 minutes longer or until noodles are cooked to desired doneness. Do not overcook egg noodles or they will fall apart and turn to mush.
Serve, garnished with fresh parsley, if desired.
Notes
Storage: Store in an airtight container in the refrigerator for 3-4 days or freeze for up to 3 months.Use any type of noodle that you’d like - thinner and flatter noodles will cook more quickly. It’s really important to monitor the noodles cooking so that they don’t overcook. You could also cook the noodles on the stovetop separately and store in a Ziploc bag in the refrigerator while the soup is cooking. Then, just mix them into the soup when serving.You can use any type of chicken for this soup also. Dark meat like thighs or drumsticks will work great. You can use bone-in meat, but be sure you remove the chicken and take it apart from the bones before it cooks so long that it starts falling off the bone as then you might end up with bones in your soup.Use bouillon to make the broth if you don’t have broth available.
