You will need one big stew pot with a lid (plus a circular rack for bottom - optional).
Let whole chicken sit in pot with warm water poured on top to come to room temperature. Boil water to cover a 2-3 lb. chicken in a stew pot. (4 cups of water equal a quart. Took 4 1/2 qts. for my 3.37 lb. chicken.) I added a rack in the pot bottom that came with my pressure cooker so chicken wasn’t touching direct heat from burner.
Add bouillon paste to 1 cup of boiling water and let it dissolve before adding to the stew pot. (Took 6 T. for my chicken.)
Add seasonings desired - 1 tsp. salt, 1 tsp. lemon-pepper, 1 tsp. poultry seasoning (optional). Stew for 45 minutes to an hour. In last 15 minutes add the vegetables - carrots, onion, celery. As the chicken cooks start making the dumplings.
Take the chicken out of the broth to cool on a platter for 15 minutes or longer until cool enough to handle. Can remove vegetables if you like as well. Remove bones, skin, and pull chicken apart into pieces. Drop the dumplings into lightly boiling broth. I timed the dumplings for 15 minutes of cooking time and tasted to check to see if done.
Add chicken pieces and vegetables back into the pot of chicken broth. Serve while hot. Serves six or more.
