Heat olive oil in a large pot or Dutch oven over medium-high heat. Add onion, leek, and garlic; cook, stirring regularly, until soft and wilted, about 10 minutes. Avoid browning.
02 -
Stir in ground coriander, ground fennel, fresh thyme, and a large pinch of salt. Cook briefly until fragrant.
03 -
Add chicken pieces and chicken stock to the pot. Bring to a boil, then reduce to a low simmer. Cover and cook until chicken is cooked through, about 30–40 minutes.
04 -
Remove chicken from the pot and set aside to cool. Shred into bite-sized pieces, discarding bones and skin.
05 -
While the chicken cooks, whisk egg and buttermilk together in a small bowl. In a large bowl, whisk together flour, baking powder, baking soda, salt, and black pepper. Add diced butter and cut into flour using your fingers or a pastry cutter until mixture resembles coarse crumbs.
06 -
Pour buttermilk mixture into the flour mixture. Add in the chopped herbs, then gently fold together until just combined; dough will be shaggy and sticky. Cover and refrigerate until ready to use.
07 -
Return shredded chicken to the pot. Add peas, asparagus, and zucchini. Taste and season with additional salt or pepper as needed. Bring the soup back to a simmer. Using two spoons or a small scoop, drop heaping spoonfuls of dumpling dough (about golf ball size) into the simmering broth.
08 -
Cover and simmer for approximately 12 minutes, until dumplings are cooked through and nearly doubled in size.
09 -
Ladle the soup and dumplings into bowls. Garnish with extra chopped parsley, chives, dill, and cracked black pepper as desired.
