Melt the butter in a Dutch oven over medium heat and cook the diced onion, carrots, and celery 5 minutes.
Add the whole chicken thighs, broth, thyme, salt, and pepper. Bring to a boil, then simmer covered 15 minutes until the chicken reaches 165°F.
Lift out the chicken, shred it with two forks, and return it to the pot.
Stir the baking mix and milk together just until a soft dough forms.
Drop heaping spoonfuls of dough onto the simmering soup, cover tightly, and cook 10-12 minutes without lifting the lid until the dumplings are fluffy and cooked in the center.
Ladle into bowls; the broth thickens as it sits, so add a splash of broth if reheating.
