Melt butter in a large pot over medium heat. Add onion and celery and cook until just tender, add carrots and cook a little longer.

Add chicken broth, vegetable broth, chicken, egg noodles, basil, oregano, salt, and pepper. Stir to combine and bring to a boil.

Reduce heat and simmer for 20 minutes.

Hint: No need to precook chicken, cooking process does this for you. 1 less dish to clean!
