Melt the butter in a large Dutch oven over medium heat. Add onion, celery, carrot, and 1/2 teaspoon salt, then cook for 5-6 minutes until the onion softens.
02 -
Add chicken broth, chicken base, black pepper, and chicken. Bring to a simmer, lower the heat, and cook gently for 18-22 minutes until the chicken reaches 165 degrees F and shreds easily.
03 -
While the chicken cooks, stir flour, baking powder, and salt in a bowl. Add buttermilk and mix just until a shaggy dough forms.
04 -
Turn the dough onto a floured surface. Roll to about 1/4 inch thick, then cut into 1-inch squares. Dust lightly with flour so the pieces stay separate.
05 -
Transfer the chicken to a plate. Strain the broth into a bowl, discard the vegetables, and return the broth to the pot. Shred the chicken into bite-size pieces.
06 -
Bring the broth to a steady simmer. Add dumplings a few at a time, stirring gently between additions so they do not clump.
07 -
Return the shredded chicken to the pot. Simmer 15-18 minutes, stirring gently, until the dumplings are tender and the broth has thickened. Taste and adjust salt and pepper.
08 -
Turn off the heat and let the chicken and dumplings stand for 5 minutes before serving so the broth settles into a creamy gravy.
