Prep the Ingredients: Peel and slice the carrots and onion, and chop the celery and mince the garlic.
Start the Crockpot: Turn it on low or high depending on what setting you plan to cook the soup. Place the chicken breasts into the bottom of the crockpot.
Add the Vegetables and Seasonings: Add the carrots, celery, onion, and garlic over the chicken in the crockpot. Sprinkle salt and pepper over the vegetables and chicken.
Adding Soup Base: Pour the broth into the crockpot, making sure that the chicken and vegetables are covered. Next, add one can of cream of chicken soup and the bouillon cubes.
Cooking: Cover the crockpot with its lid. Cook on high heat for 3-4 hours or low heat for 6-7 hours or until the chicken is tender and cooked through. Remove the chicken and easily shred with a fork then add the shredded chicken back to the crockpot.
Add the Egg Noodles: About 30 minutes before you plan to serve the soup, add the heavy cream and egg noodles to the crockpot. Stir well, making sure the noodles are submerged in the liquid.
Continue to cook on low heat, allowing the noodles to cook until they are tender.
Final Touch: Taste the soup, and adjust the seasoning if necessary.
If the soup is too thick, you can add a bit more water to reach your desired consistency.
