My basic chicken soup recipe:

heat butter in a large pot, put diced celery, onion, and carrots in, then salt and season - if you have them, my chicken soup seasonings of choice are pepper, thyme, sage, and garlic powder, but some other herbs could be good too. Once the vegetables have sweated, add broth and a bay leaf if you've got it, bring to a boil. If you want to add noodles or rice, add them according to their cook time, and add chicken chunks about 7 min before it's done

You can def add or sub other things depending on what to have on hand and what sounds good to you!
