Start by dicing the chicken breast into bite-sized pieces.
In a large pot or Dutch oven, heat a drizzle of olive oil over medium heat. Add the diced celery and carrots, sautéing for about 5 minutes until they begin to soften.
Stir in the diced chicken and cook for an additional 5 minutes until it’s no longer pink. Then, pour in the chicken broth along with the bay leaves and dried thyme. Bring the mixture to a gentle boil.
Once boiling, add the egg noodles to the pot. Let them cook according to package instructions, usually about 6-8 minutes, until they are al dente.
While the noodles are cooking, whisk together the egg yolks in a separate bowl. Slowly ladle a cup of the hot soup broth into the egg yolks while whisking continuously.
Once the egg yolk mixture is ready, slowly stir it back into the soup. Remove the bay leaves, and let the soup simmer for an additional 2-3 minutes to thicken slightly. Serve warm and enjoy!
